JavaScript - Ajax Select Question Inline Html
Hi,
I have what is probably a stupid issue. I have a select box that is being filled by an an ajax request to a SQL DB and returns the results in a select box. That part works fine. The second part of the request is that i also want my inline html to change results if i change my selection. that part is not working. I tried to put my onchange event into the option in php, but that doesn't return anything either. $display_string .= "<option onchange=\"getSoftwareUpdate();\"> $row[Software] </option>"; clear as mud? Any help would be much appreciated! //this section gets the results from the php script and returns back the values in the db. <script language="javascript" type="text/javascript"> <!-- //Browser Support Code function getSoftwareFunction() { var ajaxRequest; // The variable that makes Ajax possible! try{ // Opera 8.0+, Firefox, Safari ajaxRequest = new XMLHttpRequest(); } catch (e){ // Internet Explorer Browsers try{ ajaxRequest = new ActiveXObject("Msxml2.XMLHTTP"); } catch (e) { try{ ajaxRequest = new ActiveXObject("Microsoft.XMLHTTP"); } catch (e){ // Something went wrong alert("Please contact Trinity Help Desk at ext. 88817"); return false; } } } // Create a function that will receive data sent from the server ajaxRequest.onreadystatechange = function(){ if(ajaxRequest.readyState == 4){ var ajaxDisplay = document.getElementById('ajaxDiv'); ajaxDisplay.innerHTML = ajaxRequest.responseText; } } var SoftwareName = document.getElementById('results').value; var ManufacturerName = document.getElementById('results').value; var VersionName = document.getElementById('results').value; var InstallLocationName = document.getElementById('results').value; var queryString = "?Software=" + SoftwareName + "&Manufacturer=" + ManufacturerName + "&Version=" + VersionName; + "&InstallLocation=" + InstallLocationName ajaxRequest.open("POST", "getSoftwareName.php" + queryString, true); ajaxRequest.send(null); } </script> //this next part i want to return the results based on an onchange event in the select option <script language="javascript" type="text/javascript"> <!-- //Browser Support Code function getSoftwareUpdate() { var ajaxRequest1; // added try{ // Opera 8.0+, Firefox, Safari ajaxRequest1 = new XMLHttpRequest(); } catch (e){ // Internet Explorer Browsers try{ ajaxRequest1 = new ActiveXObject("Msxml2.XMLHTTP"); } catch (e) { try{ ajaxRequest1 = new ActiveXObject("Microsoft.XMLHTTP"); } catch (e){ // Something went wrong alert("Please contact Trinity Help Desk at ext. 88817"); return false; } } } //added // Create a function that will receive data sent from the server ajaxRequest1.onreadystatechange = function(){ if(ajaxRequest1.readyState == 4){ var ajaxDisplay1 = document.getElementById('ajaxDiv1'); ajaxDisplay1.innerHTML = ajaxRequest1.responseText; } } //end add var Software = document.getElementById('results').value; var SoftwareName = document.getElementById('results').value; ajaxRequest1.open("POST", "getSoftwareName1.php" + SoftwareName, true); ajaxRequest1.send(null); } </script> <html> <div id='ajaxDiv1'></div> <div id='ajaxDiv'> <select id='results' onchange="getSoftwareUpdate();" name="Software"> </select> </div> </html> </td> Similar TutorialsHi, I'm looking to add the functionality of 'inline editing' with AJAX. I have found a good piece of code from a website (http://www.yvoschaap.com/weblog/ajax...pdate_text_20/) which does it well but I want to improve it slightly. I have a span tag with text in it which turns into an input box when a user clicks on the text. The user edits the input box and then click away from the input box in order to save the change and the input box turns back into regular text. How do i make it so when the person clicks on the text the input box appears but also an 'Update' and 'Cancel' link appears to the side of it so that the user can only update or cancel that field by clicking on the links. The code that does this is as follows: HTML CODE: Code: <span id="userName" class="editText">John Doe</span> JAVASCRIPT - controls when text is clicked for input to appear: Code: //edit field created
function editBox(actual) {
//alert(actual.nodeName+' '+changing);
if(!changing){
width = widthEl(actual.id) + 20;
height =heightEl(actual.id) + 2;
if(height < 40){
if(width < 100) width = 150;
actual.innerHTML = "<input id=\""+ actual.id +"_field\" style=\"width: "+width+"px; height: "+height+"px;\" maxlength=\"254\" type=\"text\" value=\"" + actual.innerHTML + "\" onkeypress=\"return fieldEnter(this,event,'" + actual.id + "')\" onfocus=\"highLight(this);\" onblur=\"noLight(this); return fieldBlur(this,'" + actual.id + "');\" />";
}else{
if(width < 70) width = 90;
if(height < 50) height = 50;
actual.innerHTML = "<textarea name=\"textarea\" id=\""+ actual.id +"_field\" style=\"width: "+width+"px; height: "+height+"px;\" onfocus=\"highLight(this);\" onblur=\"noLight(this); return fieldBlur(this,'" + actual.id + "');\">" + actual.innerHTML + "</textarea>";
}
changing = true;
}
actual.firstChild.focus();
}
JAVASCRIPT - Initiated the update of the field. Code: function fieldBlur(campo,idfld) {
if (campo.value!="") {
elem = document.getElementById( idfld );
remotos = new datosServidor;
nt = remotos.enviar(urlBase + "?fieldname=" +escape(elem.id)+ "&content="+escape(campo.value)+"&"+formVars,"");
elem.innerHTML = nt;
changing = false;
return false;
}
}
I tried playing around to do it myself by adding an <a> link with an onclick event handler in the editBox() function ie. Code: onlick="noLight(this); return fieldBlur(this,'" + actual.id + "');" But i realise that the two values passed to the function need to be changed as i cannot use (this) if it's not within the input box? If anyone could help me with this query it would be greatly appreciated. I hope Ive given enough info and have expressed my problem clearly. If you have any questions let me know and I'll answer them ASAP. If you would like to see the whole source please go to the original website where i got it from - http://www.yvoschaap.com/weblog/ajax...pdate_text_20/ Thanks in advance Hi, I was just wondering is it possible to have an onclick() JavaScript function that would use PHP to INSERT a new row into a MySQL table? Like is it possible to put some php into a javascript function that runs when I click the button on my page? Something like that? The PHP updates the MySQL database and the JavaScript tells the PHP when to happen? Just wondering what's the best way to go about that. I have Code: var myresult;
var myresult2;
var vresult;
function validateusername(username) {
var validusername = true;
// alert(mobilenumber);
http.abort();
http.open("GET", "checkusername.asp?username=" + username, true);
//alert("here");
http.onreadystatechange = function() {
if (http.readyState == 4) {
myresult = http.responseText;
// alert(myresult);
if (myresult == "True") {
validusername = true;
}
else {
alert("username exists ");
validusername = false;
}
}
}
http.send(null);
return validusername;
}
function validatemessage(message) {
var validmessage = true;
http.abort();
http.open("GET", "checktext.asp?message=" + message, true);
http.onreadystatechange = function() {
if (http.readyState == 4) {
myresult2 = http.responseText;
// alert(myresult);
if (myresult2 == "True") {
validmessage = true;
// alert("valid message is true")
}
else {
alert("You cannot put emails or telephone numbers in any of the details fields");
validmessage = false;
}
}
}
http.send(null);
alert(validmessage);
return validmessage;
}
and then within my validation if (!validateusername(document.getElementById("x_Username").value)) { return false; } and if (!validatemessage(document.getElementById("x_On_Self").value)) { return false; } Now if I just validate one (like just the uername or must the message field then it works but if I leave the validation to both then if one returns false - it causes both to - what am I doing wrong? Hello, everyone... I have this problem that is really bugging me. I am trying to implement this script found in Javascriptkit: http://www.javascriptkit.com/script/...ltooltip.shtml It has a very unique feature of grabbing arbitrary HTML tags and attaching tooltips to them. Priceless to my site. But the problem is, the script only works with jQuery up to 1.2.6... after that version, it stops working entirely. Quite an issue, as you can imagine. It also has some issues with browsers other than Firefox that I hope updating the code might fix. I don't have any lead on this... could anybody look into the code and tell me what's wrong? Thank you, There are some VERY similar questions and answers, but I have been unable to get them to work for me. The simple situation is calculate days since a date with JS, and output it as part of a text line: create variable xxx with subtraction, or datediff() <body> <p>XYZ has been in effect for (xxx) days.</p> </body> Nothing more, & thanks.

FYI datediff() is not an official JS function. What I normally do is get the date as a UTC number (millsecs after an old date) do the math and then convert back. Code: <!DOCTYPE html>
<html lang="en">
<meta charset="utf-8" />
<head>
<title></title>
</head>
<body>
<div id="her" style="clear:both;"></div>
<script type="text/javascript">
var d1 = new Date("january 01, 2015");
var d2 = new Date();
var work = d2.getTime() - d1.getTime();
var xxx = Math.round(work/86400000);
document.getElementById("her").innerHTML = 'XYZ has been in effect for '+xxx+' days.';
</script>
</body>
</html>
The number 86400000 comes from 1000*60*60*24 to convert millisecs to days What would be the best way to get data for a mobile site. I've tried using Jquery $.ajax to bring in the data from a php file. It seems to work however it takes some time to load without a way to really give a progress meter. I was wondering what the fastest way to do this would be. For instance it loads and loads then after a long while the alert(); pops up and the data loads into the page. Ultimately i was thinking i could use the ajax request to read in the data from the mysql database server, then transfer it to localstorage, im using HTML5 primarily for the development also just for reference. Somewhat new to mobile development i was just wondering if anyone had a starting point for me to look at and go from there. Code: $(document).ready(function($){
var dataret = 0;
$.ajax({
type: 'POST',
url: 'mobile.php',
beforeSend: function(){
$('#status').show();
},
success: function(data){
//initialize localstorage here
alert('success');
// if it takes as long as it does, a few minutes, at least show a loading bar...
$('#progress').progressbar({
});
},
dataType: 'json'
});
});
Thanks in advance! First post here and its a "is this possible to do question?" html code: Move a div into an other div. Same thing as u move a file on the desktop into an other file. Im going to try to do this in this way html <- heres the divs, file divs and folder divs, all of them got uniqe ids java <- making it possible to move the divs, and handling what div i move where ajax <- calling a php script with the divid i moved and to what div i moved it to I know nothing about ajax and im kinda bad at javascript to, know how to move a div, and how to see what div i moved it to but nothing more. My questions is as follows, is it possible to do this? anyone know where to start? or got any good links i can watch, learn ajax from scratch or try with some Opensourceproject and learn from them? Thanks all for ur time. I'm make a ajax call to a processing PHP file that echos either "success" or an "error message". When the success is returning, i want Jquery to recognize this and then redirect the browsers instead of displaying the success message. Here are some snippets. I can only seem to parse to a blank or null. Jquery code: Code: $.ajax({
type: "POST",
url: "process.php",
data: wfLoginPost(),
success: function(msg){
alert(msg);
// both below are either null or blank
//var res = $(msg).find("span.response").text();
//var res = $(msg).find("span.response").html();
if(res == 'Success'){
window.location = 'http://www.google.com';
}
}
});
process.php PHP Code: if($qry[0]['pwd'] == $password){ echo "<span class='response'>Success</span>"; }else{ echo "<span class='response'>Username or password did not match</span>"; } Here is the contents of the msg response from the ajax post: Code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

Hi, what would be the best way to have a hidden array of possible text directed at a textarea and then if something is not within that array "onfocus", a certain select option is chosen within that form? Thanks Hi All, I have a select html control as below ; <SELECT > <OPTION VALUE="1"> This is option 1 </OPTION> <OPTION VALUE="2" >This is option 2 </OPTION> <OPTION VALUE="3" >This is option 3 </OPTION> </SELECT> My requirement is that when user moves pointer over the items the value of the item should be shown in a hint box. How could I show the value of the item in a hint box as user moves pointer over an item using javascript? Thanks, Dev I have a dropdown menu. the code is as below: <html:select name="data1" property="accountNumber" styleClass="formContent" > <option>Id1 </option> <option>Id2 </option> I need to give user an option to select from the list or enter a new value. how do you do this ? I can add another option say "new value" and when he choose this user should be able to add the new value/ please help !! I'm new to java script. I have a html:select tag box and I want to make it copy pastable directly from an excel sheet or notepad so as to dynamically updating its options, is it possible. Current code has html:select box separately and below this another text box is there, where i fill the numeric value, then press add button below and then it gets updated in the html:select tag box. Is it possible to copy from some list of numeric values and then directly paste into the html:select and the array list gets updated from this pasted list. Thanks in advance fro your replies. Hello, I'm trying to populate an HTML drop down list with data from an XML file but have failed miserably so far using examples I've found. Please help. Thanks, Richard hi, all... haven't found exactly the solution here, and trying to cobble something together but it's just not working. php is doing the heavy lifting in terms of generating the code, but the upshoot is i have a script: Code: <script type="text/javascript">
var values[1] = "This layout includes a 'title' and 'body' content block.";
var values[2] = "This layout features everything included in the Standard Page layout as well as a 'comments' block.";
function replaceText( var_id) {
document.getElementByID(pageLayout_replace).innerHTML = values[var_id];
}
</script>
and a select box: Code: <fieldset> <legend>Page Layouts</legend> <label for="pageLayout" class="half left">Choose a page layout<br /> <select name="pageLayout" id="pageLayout" size="5" onChange="replaceText(this.options[this.selectedIndex]);"> <option value="1">Standard Page</option> <option value="2">Standard Page w/Comments</option> </select> </label> <label class="half right"> Page Layout Description:<br /> <span id="pageLayout_replace">Click on a page layout title to the left to get a description here.</span> </label> </fieldset> however, the error console in firefox says Code: Error: missing ; before statement
Line: 14, Column: 8
Source Code:
var values[1] = "This layout includes a 'title' and 'body' content block.";
and then when i try to select one of the items, Code: Error: replaceText is not defined Line: 1 any insight? thanks in advance! Dear all, background information: I did code a timesheet management system for my company with PHP where the user has to submit time entries and has an online form with several start and end times. The start and end times are all simple HTML select option dropdowns. I want that the first End time selection will be the next start time selection. Basically a simple dependency of the dropdown. My approach was that I want to solve this with JavaScript. In my php code I am echoing the following (in this select the end times are the values): echo "<select class='normal' name='$field_id' onChange=set_time_hour(this.value,'$field_id_js')>"; When the user changes then the end time dropdown the next field (next start time entry) should be changed accordingly. The javascript looks like this function set_time_hour(hour_value,next_field){ alert (hour_value); alert (next_field); document.getElementById(next_field).value = hour_value; } The alert calls are giving me the right values. but the document.getElementById(next_field).value = hour_value; is not working. What is wrong there? Do you have an idea? How can I change the value of a select box with Javascript? The select box values are already popoluated with PHP so I just want to select the right value. Hi, I am hoping I just need to be pointed in the right direction with this. I have Page1. When Page1 body onloads it uses Ajax to call PartA Within PartA I have a message board so members can write messages which will be sent to my database in PartA[1] and immediately posted for view on to PartA[2]. As I want to have my request to the server updating regularly I want to have PartA[2] on a timed loop to refresh - I do not need the content of PartA[1] to refresh. So the order of events would look like this: Page1 | onload call | v PartA / \ V V PartA[1] PartA[2] (loads once) (constantly refreshes) What I am not sure about is that I have <body> and <head> attributes in Page1 only. I have already used my body onload to call PartA (and can't use it to call PartA[2] before PartA has loaded anyway). I do not want the user to have to click a button or do anything to call up PartA[2]. So my question is how would I get PartA[2] to automatically load within PartA? I hope I have made this clear, but if I haven't let me know and I will try again. I am very new to javascript and really can't figure out what I am doing wrong. I am trying to make a 1 page store that allows you to type in an item and select the color and size you want for that item. If you don't fill in a field, an alert message should tell you that. If all the fields are filled in, a "thank you for purchasing ____________" message should appear in a text area at the bottom of the page. This is my current code: Code: <html>
<head>
<script>
function processform()
{
if ( document.form1.item1.value == "")
{
alert("No Item Chosen")
}
else
{
chosen = ""
len = document.form1.c1.length
for (i = 0; i <len; i++) {
if (document.form1.c1[i].checked) {
chosen = document.form1.c1[i].value
}
}
if (chosen == "") {
alert("No Color Chosen")
}
}
else {
itemname = document.form1.item1.value;
itemcolor = document.form1.c1.value;
itemsize = document.form1.size.value;
document.form1.txtarea1.value = "Thank you for purchasing a " + itemsize + " " + itemcolor + " " + itemname;
}
}
</script>
</head>
<body>
<h1>Store</h1>
<br/><br/>
<form name="form1">
<h4>What item would you like to buy?</h4>
<input type="text" name="item1" value="" /><br />
<br/><br/>
<h4>Color</h4>

<input type="radio" name="c1" value="yellow" /> Yellow<br />
<br/><br/>
<h4>Size</h4>
<select name="size">
<option value="small">Small</option>
<option value="medium">Medium</option>
<option value="large">Large</option>
<option value="extra large">Extra Large</option>

<br/><br/>
<button onclick="processform()">Purchase</button>
<br/><br/>
<textarea rows="2" cols="40" name = "txtarea1"> </textarea>
</form>
</body>
</html>
When I press the purchase button, no alert message is shown, nor does anything get displayed in the textarea. What am I doing wrong? Hey chaps, hope someone can help with this: I have a PHP form, with a couple of dynamic Select menus, which are populated from two SQL tables: // tbl_main_colour: Code: ID, NAME 1, Red 2, Blue 3, Green // tbl_shade_colour: Code: ID, NAME, FK_MAIN_COLOUR_ID 1, Light Red, 1 2, Dark Red, 1 3, Light Blue, 2 4, Dark Blue, 2 5, Light Green, 3 6, Dark Green, 3 What I'm after is something to filter the second select option, after the first select option has been chosen // Select 1: Code: Red // Select 2: Code: Light Red Dark Red I'm pretty sure this is possible, but not sure how to go about it, any help would be most appreciated. I've been having problems getting my select option to change the options of another select option. I'm not much of a javacsript coder, so I'm at a lost. When I select the first option nothing appears in the second option. here's the javascript code: Code:
function createOption(OptionText, OptionValue){
var temp = document.captcha_form("option");
temp.innerHTML = OptionText;
temp.value = OptionValue;
return temp;
}
function valChange(){
var firstList = document.getElementById("emailaddress");
var secondList = document.getElementById("subject");
while(secondList.hasChildNodes())
secondList.removeChild(secondList.childNodes[0]);
switch(firstList.value){
case "1":{
secondList.appendChild(createOption("Report Site Browsing Issue", Report Site Browsing Issues));
secondList.appendChild(createOption("Report Page Errors", Report Page Errors));
secondList.appendChild(createOption("Other", Other));
break;
}
case "2":{
secondList.appendChild(createOption("Report Unauthorized Game", Report Unauthorized Game));
secondList.appendChild(createOption("Report Spam", Report Spam));
secondList.appendChild(createOption("Report Harassment", Report Harassment));
secondList.appendChild(createOption("Report Illegal Activities", Report Illegal Activities));
secondList.appendChild(createOption("Request Account Removal", Request Account Removal));
break;
}
// ....
default:{
secondList.appendChild(createOption("Please select from the first list", ""));
break;
}
}
}
window.onload = valChange;
this is the form code Code: <div class="mailto_form"> <form method="POST" id="captcha_form" name="captcha_form" action="../includes/mailform.php"> <div style="padding-bottom: 1em;">Choose Recipient: <select name="emailaddress" id="emailaddress" onchange="valChange();"> <option value=""></option> <option value="1">Webmaster</option> <option value="2">Admin</option> </select> </div> <div style="padding-bottom: 1em;">Subject: <br /><select name="subject" id="subject"> </div> <div style="padding-bottom: 1em;">From: <br /><input type="text" name="email" id="email" value=""> </div> <div style="padding-bottom: 1em;">Enter the text contained in the image into the text box: <br /><img src="../includes/captcha.php" /> <br /><input type="text" name="userpass" value=""> </div> <div style="padding-bottom: 1em;">Message: <br /><textarea name="message" id="message" rows="10" cols="60"><?php echo "</tex" .

Now, what I'm desperately trying to do since 4-5 hours is to have the search results between the <div id="searchcontrol"></div> encoded as HTML in the loaded page. Currently, when the page is loaded and I look at the source code, I have the word 'Loading...' in the <div> tags, despite in the normal view there are G results listed. I need those results encoded as HTML for SEO reasons. Researching on this matter I thought the problem could be the OnLoad command, that makes the script load after all the other HTML elements are loaded. But I tried to make it load before all the elements in the page, and the problem persists. How can I solve this? Thanks in advance for any help! |
