JavaScript - Ajax Not Working With Dynamically Loaded Textbox When Used With Keyup
Can somebody help me to find the problem with the below given code, its not working.
$(document).on('keyup', ".add_commi", function() { typingTimer = setTimeout(doneTyping, doneTypingInterval); var pro = $(this).attr('id'); var selectvalue = $(this).html(); var id = pro.slice(-2); var amount = $('#amount'+id).html(); var rate = $('#v_rate'+id).html(); //alert('working'); var data = 'cur_amount='+cur_amount +'&cur_rate='+cur_rate+'&commision='+selectvalue; $.ajax({ type: "POST", dataType: "json", url: "http://localhost/agent/buy-currency-calculations/", data: data, success: function(output){ var cus_rate = output.cus_rate; var total = output.total; var tot_commision = output.commision; alert(cus_rate, total, tot_commision); $('#curr_rate'+id).html(cus_rate); $('#tot'+id).html(total); $('#tot_commi'+id).html(tot_commision); } }); return false; }); Reply With Quote 01-09-2015, 02:53 PM #2 Dormilich View Profile View Forum Posts Senior Coder Join Date Jan 2010 Location Behind the Wall Posts 3,532 Thanks 13 Thanked 372 Times in 368 Posts cur_amount, cur_rate and selectvalue are supposedly primitive values (like numbers) but you fetch them as HTML code which the interpreting server script certainly can’t process. (if it should be indeed primitives, you should rather consider using form elements for that). despite that jQuery has a method to fetch values off a form, which might be easier to implement, but that depends on the used HTML code. additionally, in your browser’s dev tools you can check the network pane for what values are sent/received in the AJAX call. Similar TutorialsI currently found a script that loads an ASX playlist dinamically, allowing the user to choose the item that he wants to watch in Windows media player embedded. The trouble is that once the user click on the link in the playlist it wont work. Take a look here http://tv.mghospedagem.com/wmp-pl3.html Works only on IE. Code: <head>
<script language="javascript1.2">
playListLoaded=false;
function loadPlayItems() {
df=document.getElementById("playItem");
dp=document.getElementById("playlist");
WMP9=document.getElementById("MediaPlayer1");
WMP9.url="http://tv.mghospedagem.com/play.asx";
WMP9.controls.play();
}
function showPlayItems() {
WMP9=document.getElementById("MediaPlayer1");
playlistItems=WMP9.currentPlaylist.count;
for (i=0; i<playlistItems; i++) {
playitem=document.createElement("a");
playnext=document.createElement("br");
playitem.setAttribute("href","#");
playitem.setAttribute("onclick","playItem("+i+")");
playitem.innerText=WMP9.currentPlaylist.item(i).name;
dp.appendChild(playitem);
dp.appendChild(playnext);
}
playListLoaded=true;
WMP9.controls.play();
}
function setPlayItem(index) {
WMP9=document.getElementById("MediaPlayer1");
playlistItems=WMP9.currentPlaylist.count;
if (playlistItems > 0) {
WMP9.controls.currentItem=WMP9.currentPlaylist.item(index);
WMP9.controls.play();
}
}

I'm trying to write a progressively enhanced web application. I have an index page and a form with some select boxes and some radio buttons on a different php page. Before enhancement occurs, the form is accessible via regular links and everything works as expected. No issues. In the enhanced version of the application, the form is AJAXed into the index page. When this occurs, the select boxes in the form work perfectly. The radio buttons are initially unchecked and I can check one option as usual. However, once one is checked, clicking the other radio options does nothing. I am unable to check a different option. Anybody got a clue what the problem is? Using Chrome by the way. Firefox is the same as Chrome. In IE I can't even check a radio button the first time. Here's the code that's ajaxed in: Code: <label>First Time Buyer Status <!--These values can't be 1/0 because 0 stands for not set--> <input type="radio" name="FTB" id="FTBYes" value="1" <?php $M->checkFTBValue(1); ?> title=""/>First Time Buyer <input type="radio" name="FTB" id="FTBNo" value="2" <?php $M->checkFTBValue(2); ?> title=""/>Not First Time Buyer </label> The PHP script you see there checks if the value on the server matches the value of the radio button and echo's checked="checked" if true. I thought this could be causing the problem initially but the exact same code is used in the non-enhanced version and it works fine. I tried commenting it out anyway but it makes no difference. The only thing I can think of is that some javascript is preventing me from selecting a different radio option. That would explain why it works ok in the non-enhanced version because there is no JS there. I can't find anything that I've written that might cause this effect I'm using jQuerys form plugin on my pages. I'm going to try writing it out and see if that fixes anything. Any body ever experience a similar problem with this? In the mean time, is there a way I can check if any JS functions when I click on the radio button? Sorry if this is in the wrong forum, there's so many different languages involved, I hadn't a clue where to put it. hi this is santosh first off all thanks in advance to all who r reading my question im in prblm in my project in 1 file i have to first display textbox in html statically which will hav + & - button preceding it , & on click of + button one more textbox should appear dynamically & first textbox + button should disapper & it should hav only - button & the textbox which was dynamically generated now on click of first textbox + button should hav + & - button & it should go on. & on click of - button textbox which is in front of it should get deleted. here i tried alot but my code is showing + & - button to every textbox that is dynamically generated which is not the requirement plz help me im in great need. earlier also i hav submitted my queries & got a fully satisfied result bcoz of that now im having great hopes from u & this site plz reply as early as possible waiting for ur reply again thanks in advance Hello, I'm very new to javascript and am probably dabbling in stuff that I shouldn't if I am new to it. Nonetheless I've exhausted my resources and am seeking some answers from people who know what they're talking about. I've got this XML file: Quote: <?xml version="1.0" encoding="utf-8"?> <Menu> <Section> <Title>Product Information</Title> <Topic url="howto.html">How to use This Product</Topic> <Topic url="product.html">Product Overview</Topic> <Topic url="sysreq.html">System Requirements</Topic> </Section> ..... </Menu> There's more data than that but for brevity that's the way it's constructed and repeats with several Titles and Topics. Here's the JS i'm using to build a dynamic menu. The goal is to pick up the data and build an Accordion menu out of it: Quote: if (window.XMLHttpRequest) { xhttp=new XMLHttpRequest(); //create ajax var } else { xhttp=new ActiveXObject("Microsoft.XMLHTTP"); //IE } xhttp.open("GET","menu.xml",false); xhttp.send(""); xmlDoc=xhttp.responseXML; document.write("<div class='acc'>"); var x=xmlDoc.getElementsByTagName("Section"); for (i=0;i<x.length;i++) { document.write("<dt>"); document.write("<a href='#'>" + x[i].getElementsByTagName("Title")[0].childNodes[0].nodeValue + "</a></dt>"); document.write("<dd><ul>"); var y=xmlDoc.getElementsByTagName("Topic")[0].childNodes[0]; for (foo=0;foo<x.length;foo++) { document.write("<li class='acc_item'><a href='#'>" + x[i].getElementsByTagName("Topic")[0].childNodes[0].nodeValue + "</a></li>"); } document.write("</ul></dd>"); } document.write("</div>"); It creates the menu correctly... to a point. It has the correct styling, the accordion works perfectly, it has the correct Titles in the correct places, but when I "expand" one of the Titles it lists the first topic only, and lists it 5 times (the same amount of Titles I have). It then repeats this for every section. Example: Product Information How to Use This Product How to Use This Product How to Use This Product How to Use This Product How to Use This Product I'm not very confident in the syntax, or what it is exactly doing. Any guidance would be very appreciated. Please keep in mind I'm very new. Thanks! I've been fooling around with developing an IETMs interface (Interactive Electronic Technical Manual - like an interactive parts catalogue) to display the data live from an existing Access database. The idea is to be able to run this interface on a network hosted intranet with straight HTML, plain Javascript, VBScript & ActiveX objects, so that it doesn't require IIS etc to run ASP or PHP etc (I don't want to involve corporate IT for the IIS). All is going pretty well, & I'm impressed with the setup except for a few minor things - checking if a frame is loaded, & global variables. My setup is a HTML page hosting 5 frames with each containing an empty <DIV> (which gets the page written to it dynamically), but I need to ensure all frames are loaded before getting into the heavy stuff (which Javascript is handling brilliantly!). But I'm finding that Javascript sux at truly detecting if a frame is loaded (someone please prove me wrong!). I have all 5 frames call a function fnInitialiseIfReady(), then if I could either successfully test if all frames are loaded, or if I could globally count if this function has been called 5 times, I can proceed with confidence & call my function fnInitialise(). But unfortunately neither is working for me. From tireless internet searches, I've tried the 'frames always load in order' theory, & that is simply not correct. I have set up a test with the frames calling a function passing their name as a parameter, & each time the frames load in a different order every time. It is totally random. Note: I proved this by having the first 4 frames call a certain function(which contains an alert() line showing the frame name parameter passed), & having the last frame call a different function (which contains an alert("all are loaded!") line). The "all are loaded!" does not always appear last. I've also tried the '.frames["FrameName"].document.loaded' approach, & it ALWAYS returns 'undefined' for every frame. Am I doing something wrong here? I've also tried the '.frames["FrameName"].window.location.href' approach & it ALWAYS returns the html filename regardless of whether that page has loaded or not, so it is not an indicator of loading completion. I've also tried the '.frames["FrameName"].document.location' approach & it's ALWAYS the same as the '.window.location.href' approach. Also, I'm finding Javascript will not hold global variables for me at all. I don't know if it's a combination of multiple frames & using Javascript & VBScript together, but global variables just do not hold a value at all. Local variables (within functions) are fine. Any ideas? I don't have many globals, so I'm thinking of using a cookie. A valid Solution? BTW, the reason for also using VBScript is that it accesses the ActiveX controls by default, & being a corporate intranet app I can guarantee MSIE usage. It's frustrating because if I can solve these 2 relatively minor issues, then I'm super impressed with the robustness of this Javascript/VBScript approach. By leveraging each of their strengths, it's crunching the data just as quickly as the VB, C#, & C++ programs I've written for this particular dataset. I'm impressed! Thanks in advance, Dave Lock. Hi, While i am binding a value to a text box using java script. It will properly in all browsers other than IE. In IE the value bind as 'undefined' in the text box . so please provide solution for this one. The code sample is given below. In this "Flight Search " is the text box id . I have to bind that value from the previous page selected value. function SelectAirport(val) { var id = val + "_lnkCity"; var lnk = document.getElementById(id); window.opener.document.getElementById("FlightSearch").value = lnk.text; window.opener.document.getElementById("destinationSearch").value = lnk.text; window.close(); } Good day! I have a question regarding textbox properties. In my textbox username I want to happen is when I input a letter for example is "l" all the letter started in "l" in my field username was appear, so that the user can choose what she want to type to lessen the time in typing like in the google search. Is it possible?How can I do that? Thank you in advance Code: function addEvent(elem,type,func) {

I am also trying to emplement some of the codes in a small application I had built strictly with server side code. What it does is: two input fields for user defined values. Once the user inputs the two values, they are passed to the action page, some simple math is performed on these 2 values, and then 4 different resluts are displayed back on the action page. What I wanted was of course to make this asynchronous and display the results without a page reload. So, when I reworked the book code for my own use, and try to run the application, I get an error saying my url variable is undefined. The value of the first input seems to be passed though. One thing of note to mention is the application was written in coldfusion. The form values are passed using cf. Not sure if that matters. I mean cf works well with js and ajax, but maybe my original procedure doesnt work with my js code as it is now. Here is the javascript/ajax code: PHP Code: <script type="text/javascript" language="javascript"> var request = null; try { request = new XMLHttpRequest(); } catch (trymicrosoft) { try { request = new ActiveXObject("Msxm12.XMLHTTP"); } catch (othermicrosoft) { try { request = new ActiveXObject("Microsoft.XMLHTTP"); } catch (failed) { request = null; } } if(request == null) alert("Error creating request object!"); } function getLampVolts() { var lamp = document.getElementById("lampVoltage").value; var url = "calculatorAction.cfm?lamp = " + escape(lampVolts); request.open("GET", url, true); request.onreadystatechange = updatePage; request.send(null); } function updatePage() { if(request.readyState == 4) { if(request.status == 200) { var lumens = request.responseText; document.getElementById("lumens").value = lumens; } else alert("Error! Request Status is " + request.status); } } </script> Here is the form: Code: <form action="calculatorAction.cfm">
<table>
<tr>
<th>Lamp Voltage</th>
<td><input name="lampVoltage" id="lampVoltage" type="text" /></td>
</tr>
<tr>
<th>Socket Voltage</th>
<td><input name="socketVoltage" id="socketVoltage" type="text" /></td>
</tr>
<tr>
<td><input type="button" value="Submit" onClick="getLampVolts();" /></td>
<td><input type="reset" value="Reset" /></td>
</tr>
</table>
and here is my action page calculatorAction.cfm: Code: <cfparam name="bulbCalculator.cfm" type="any" default="0">

<cfset lampVolts = FORM.lampVoltage>

Again, the url variable says it is undefined. But the variable "lamp" contains the form field value. Thanks for any help and tips in advance! ** sorry for posting this here. Kinda rushed on time, hoping for some clues. Hello, I am using this code: using prototype too. Code: Code: var haveData = false;
[xmllink1, xmllink2, xmllink3].each(function(xmlURL){
if(haveData == false){
new Ajax.Request( xmlURL, {
method: 'get',
contentType: "application/xml",
onSuccess: function( transport ) {
var titles = transport.responseXML.getElementsByTagName( 'titles' );
DO SOME WORK HERE
haveData = true;
throw $break;
}
},
onFailu function() {
return;
},
onException: function(request,error) {
return;
}
}
What I am trying to do is if my first item "xmllink1" has some data, we break out and end it and now we can 'build some structures' ie.. onSuccess If xmllink1 doesn't have any valid data, we go to xmllink2 etc.. and so forth. Basically, when I get some valid returns.. I want to then exit out of the loop and then act on my data. But I need it in order so I know that my xmllink1 is not being in a race conditiona with xmllink2 etc.. But what is happening is I have simulataneous things going on and I get an onException (because one of the links doesn't resolve or has bad data) and that ends up killing my javascript. How can I test in order.. if link1 is good, great.. exit the "each method" and act on that data.. if xmllink1 is bad (onfairlure or onexception) lets go to xmllink2 etc.... any ideas? Hi. Just started fooling around with Ajax a bit back. So far, it's been fine. Today, though, I'm hitting some error I can't figure out. It *should* work, but it doesn't, and I have no idea why. Simple HTML form page with a bit of css. No big deal. Code: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<script type="text/javascript" src="livesearch.js"></script>
<style type="text/css">
#livesearch
{
margin:0px;
width:194px;
}

{
margin:0px;
}
</style>
</head>
<body>
<form>
<input type="text" id="txt1" size="30" onkeyup="showResult(this.value)" />
<div id="livesearch"></div>
</form>type
</body>
</html>
Problem area below in bold. Code: function showResult(str){
if (str.length == 0)
{
document.getElementById("livesearch").innerHTML = "";
document.getElementById("livesearch").style.border = "0px";
}
var xmlhttp = getXMLHttpObject();
if (xmlhttp == null){
alert("Your browser does not support XML HTTP requests!");
return;
}
var url = "livesearch.php";
url = url + "?q=" + str;
url = url + "&sid="+Math.random();
xmlhttp.onreadystatechange=stateChanged ;
xmlhttp.open("GET", url, true);
xmlhttp.send(null);
}
function stateChanged(){
if (xmlhttp.readyState == 4){
alert("Never seems to hit a readystate==4");
document.getElementById("livesearch").innerhtml = xmlhttp.responseText;
document.getElementById("livesearch").style.border="1px solid #A5ACB2";
}
}
function getXMLHttpObject(){
//Current browsers
if (window.XMLHttpRequest){
return new XMLHttpRequest();
}
//For IE 5/6
if(window.ActiveXObject){
return new ActiveXObject("Microsoft.XMLHTTP");
}
else
{
return null;
}
}
My PHP file is just a simple echo statement to see that it works to that point. It doesn't. For whatever reason, it never seems to hit readyState ==4. It enters the function (I've checked with alerts), but the if statement never comes out to be true. I have no idea why. I've combed over the code for errors for a while now and I can't find anything. Any ideas? Would be much obliged. Could somebody help me please to explain what I'm doing wrong.... a have this html file with references to some javascripts (datagrid from http://www.datatables.net) and this html file work ok..I mean javascripts a css styling works with table... but when I call this page by ajax and callback (this html page) is forward back into another div , table doesn't work ....just data from page but now functionality from javascript and css styling... how should I force callback result to use javascript and css?

hi, When I navigate to a page with Ajax on my iphone or ipad, it doesn't show up, page is just blank, I have checked for errors and there is no errors?! here is my Ajax code Code: function datecheckFunction(){
var datecheckRequest; // The variable that makes Ajax possible!
try{
// Opera 8.0+, Firefox, Safari
datecheckRequest = new XMLHttpRequest();
} catch (e){
// Internet Explorer Browsers
try{
datecheckRequest = new ActiveXObject("Msxml2.XMLHTTP");
} catch (e) {
try{
datecheckRequest = new ActiveXObject("Microsoft.XMLHTTP");
} catch (e){
// Something went wrong
alert("Your browser broke!");
return false;
}
}
}
// Create a function that will receive data sent from the server
datecheckRequest.onreadystatechange = function(){
if(datecheckRequest.readyState == 4){
var ajaxDisplay = document.getElementById('ajaxDiv');
ajaxDisplay.innerHTML = datecheckRequest.responseText;
}
}
var datepicker = document.getElementById('datepicker').value;
var queryString = "?datepicker=" + datepicker;
//Add the following line
datecheckRequest.open("GET", "http://www.affordableappliancerepairs.co.uk/admin/checkdate.php" + queryString, true);
datecheckRequest.send(null);
}
Hi.. I have form and i want to input data using barcode and it will display on textbox and after input on the first textbox the focus will go to next textbox untill it will go on the last textbox and on the last textbox it will automatically save the data's on the database. How is it possible? here is my sample code: Code: <?php
error_reporting(0);
date_default_timezone_set("Asia/Singapore"); //set the time zone
$con = mysql_connect('localhost', 'root','');
if (!$con) {
echo 'failed';
die();
}
mysql_select_db("mes", $con);
?>
<html>
<head>
<script type="text/javascript">
function ini()
{
// Retrieve the code
var code =document.getElementById ("code_read_box1").value;
var code =document.getElementById ("code_read_box2").value;
var code =document.getElementById ("code_read_box3").value;
var code =document.getElementById ("code_read_box4").value;
var code =document.getElementById ("code_read_box5").value;
var code =document.getElementById ("code_read_box6").value;
// Return false to prevent the form to submit
return false;
}
</script>
</head>
<body onLoad="document.barcode.code_read_box1.focus()">
<form name=barcode onsubmit = "return ini()">
<input type="text" id="code_read_box1" value="" /><br/>
<input type="text" id="code_read_box2" value="" /><br/>
<input type="text" id="code_read_box3" value="" /><br/>
<input type="text" id="code_read_box4" value="" /><br/>
<input type="text" id="code_read_box5" value="" /><br/>
<input type="text" id="code_read_box6" value="" /><br/>
</form>

It works in Google Chrome but not Firefox and Internet Explorer. My computer has blocked Opera and I don't know how to change that. Too much energy to investigate now, I'll do so later. Are there any pros that can tell me why this is happening? I'm assuming GoogleChrome is fixing a syntax error that FF and IE don't. Code: var request;
request=false;
try {
request = new XMLHttpRequest();
} catch (trymicrosoft) {
try {
request = new ActiveXObject("Msxml2.XMLHTTP");
} catch (othermicrosoft) {
try {
request = new ActiveXObject("Microsoft.XMLHTTP");
} catch (failed) {
request = false;
}
}
}
function isAlNum(str){
return /^[a-z0-9]+$/i.test(str);
}
var preUsername;
var same;
function updatePage() {
if (username.value.length>0){
if ( request.responseText.indexOf("0") == -1 )
{userNameErrorBox.innerHTML=username.value + " has already been taken";
usernameSuccessBox.innerHTML="";}
else
{userNameErrorBox.innerHTML="";
usernameSuccessBox.innerHTML=username.value + " is available";}}
}
function nameTest()
{
if (username.value==preUsername)
{same=1;}
else
{same=0;}
if (!isAlNum(username.value))
{if (username.value.length>0)
{username.value=preUsername;}}
else
{preUsername=username.value;}
if (username.value.length>0 && username.focus && same===0)
{
userNameErrorBox.innerHTML="";usernameSuccessBox.innerHTML="";
request.abort();
var url = "/unseen/checkIfUserNameExist.php?name=" + username.value;
request.open("GET", url, true);
request.onreadystatechange = updatePage;
request.send(null);
}
if (username.value.length===0)
{ userNameErrorBox.innerHTML="";usernameSuccessBox.innerHTML="";preUsername=""; }
}
I back tracked what i did and it appears that this code Code: var url = "/unseen/checkIfUserNameExist.php?name=" + username.value;
request.open("GET", url, true);
request.onreadystatechange = updatePage;
request.send(null);
has the problem. When I set up alerts to see what works and what doesn't, this code seems to be causing the FF and IE to not work, but I can't tell what it is that's causing them to fail. This is javascript that is suppose to check if a name has been taken by another user. I'm working on a fairly large project that I wish to be the new formspring, (size wise) I procrastinated for 2 weeks of my 12 week break and now that I'm just getting started on it I'm running into an ishness load of problems... Very de-motivating Hello. I've been teaching myself HTML and CSS for a while, and now I've moved into the world of Javascript (but I'm still very much a beginner). For practice, I've been building a sample sign up form for a mock website, and I'm having problems with the birthdate section. The idea I had was to have MM, DD, and YYYY be the default values of my 3 textboxes (as an example for users), then set the value to nothing when the box gained focus. That all works fine, but I ran into problems when I tried to write an if statement to set the value back to MM, DD, or YYYY if the value was still nothing when the user clicked away. As it is now it just replaces the text inputted into the textbox (which of course is not good). Any ideas for what the problem might be? Code: <form name="signup" action="javascript:void(0);" method="post">
<table>
<tr>
<td>Date Of Birth:</td>
<td>
<input name="DOBmonth" type="text" value="MM" size="2" style="color: #555555;" onFocus="clearDOBmonth()" onBlur="restoreDOBmonth()" />
<input name="DOBday" type="text" value="DD" size="2" style="color: #555555;" onFocus="clearDOBday()" />
<input name="DOByear" type="text" value="YYYY" size="4" style="color: #555555;" onFocus="clearDOByear()" /></td>
</tr>
<tr>
<td></td>
<td><button name="Submit" type="submit" style="font-size: 1em;">Sign Up</button></td>
</tr>
</table>
</form>
<script type="text/javascript" language="javascript">
<!--
document.signup.DOBmonth.value="MM";
document.signup.DOBday.value="DD";
document.signup.DOByear.value="YYYY";
function clearDOBmonth() { document.signup.DOBmonth.value="";}
function clearDOBday() { document.signup.DOBday.value="";}
function clearDOByear() { document.signup.DOByear.value="";}
function restoreDOBmonth()
{
if ('document.signup.DOBmonth.value = ""')
{
document.signup.DOBmonth.value = "MM";
// alert(document.signup.DOBmonth.value);
}
}
//-->
</script>
Another side question, if I set a variable equal to the value of a textbox, then change the value of the variable, does that also change the value of the textbox? or is the variable no longer associated with the textbox. Example: Code: var a = document.form.textbox.value; a = blue; does document.form.textbox.value = blue? or is var a now completely independent of the textbox value? Thanks! I'm building a t-shirt shop whose interface includes a gallery of designs in an IFrame. When the user clicks on a design, a dedicated page is loaded into the IFrame which shows all the available products associated with the design the user clicked. I've put each design's image and associated page as the first and second elements of a nested array, and am using a for loop to then load all the images into the page that's shown in the IFrame when the web-site loads. It's looking beautiful, but here's the rub I've been stuck on for two days now with no solution in sight... The array, "designImages", has 37 elements (ie. designImages[0]... designImages[36]). When I click on a design image on the page, any design image, the browser (all browsers, so I can't blame Microsoft for this one ), loads the page for design #36. I've tried all sorts of things, but still cannot tell if the issue is because the dynamically generated divs are being reassigned the value [36] after the for loop's executed, or if the div id's are okay but somehow the code is rooting for [36], the last element of the array anyway. I need someone's help in enabling a click on #4 to load the page for #4, etc, etc. Here's the code below. Thanks. Code:
/* designImages[x][0] = the image source on the page;
* designImages[x][1] = the destination url on clicking the image;
*/
