JavaScript - Form And Ajax Call Integration
Hi,
I have a form which goes to my insert page which inserts the data into the table. Except I didn't want to do a redirect to another page so I thought I would do an Ajax call. Both pages work until I change it to an ajax call. I am pretty certain that it is because I took out the <form action="insert.php"> because otherwise the page would redirect but if that is the case I don't know my way around it and if it isn't the problem I'm not sure what is. But here is my code: Form: Code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Frameset//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-frameset.dtd">
<html><head>
<script type="text/javascript">
function loadXMLDoc(File,ID){
if (window.XMLHttpRequest) {
xmlhttp=new XMLHttpRequest();
}
else {
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp.open("POST",File,true);
xmlhttp.onreadystatechange=function(){
if (xmlhttp.readyState==4 && xmlhttp.status==200){
document.getElementById(ID).innerHTML=xmlhttp.responseText;
}
}
xmlhttp.send();
}
</script>
</head>
<body>
<div id="txtHint">
<form action="" method="post"/>
<div class="scroll">
<textarea rows="6" cols="60" class="input" name="para1" required="required" onclick="clearMe(this)">
Insert Paragraph 1
</textarea>
</div>
<br />
<br />
<div class="scroll">
<textarea rows="6" cols="60" class="input" name="para2" onclick="clearMe(this)">
Insert Paragraph 2
</textarea>
</div>
<br />
<br />
<input type="submit" value="Submit" onclick="loadXMLDOC('insert.php','txtHint')" />
</form>
</div>
</body>
And my insert.php is: Code: <?php
$con = mysql_connect("localhost","user","password");
if (!$con){
die('Could not connect: ' . mysql_error());
}
mysql_select_db("mydb", $con);
$sql="INSERT INTO abc (para1, para2, date, time)
VALUES
('{$_SESSION['para1]}', '{$_POST['para2']}',CURDATE(), CURTIME())";
mysql_query($sql) or die('Error: ' . mysql_error());
mysql_close($con)
?>
Similar TutorialsHi, 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. Right for day's i've searching for a jQuery/js/ajax script that opens like facebooks box where you can delete things update posts and so on... But i don't want that facebox thing i want a tut where i can buy things that will insert into the database and delete things and sooo on... I've made the box i just want the script for it.... I'm not good with js/jQuery/ajax.... Thanks. hihi i am doing a project regarding ajax how am i going to call the title because normally if you call start year is like var detail = eval.... then for loop it inside should be var start year="" startyear += ...[i].startyear something like this but how am i going to call the title inside the note? Code: {
"infos": {
"info": [
{
"startYear": "1900",
"endYear": "1930",
"timeZoneDesc": "daweerrewereopreproewropewredfkfdufssfsfsfsfrerewrBlahhhhh..",
"timeZoneID": "1",
"note": {
"notes": [
{
"id": "1",
"title": "Mmm"
},

I'm poking in the blind with javascript and hope that you can help with this issue. A javascript function is making a call to an external php file, which checks the compares the current time with a time stored in a mysql database. If a certain time passes, the php will send back instructions to redirect the user to a different page. The issue is that the page refreshes every time the is javascript function is executed. This resets any forms, or videos that the user is watching on the page. Here is the relevant code: Code: function checkTimer()
{
if (window.XMLHttpRequest)
{// code for IE7+, Firefox, Chrome, Opera, Safari
xmlhttp=new XMLHttpRequest();
}
else
{// code for IE6, IE5
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp.onreadystatechange=function()
{
if (xmlhttp.readyState==4 && xmlhttp.status==200)
{
window.location.href = xmlhttp.responseText;
}
}
xmlhttp.open("POST","php/5minforpage10.php",true);
xmlhttp.send();
}
window.setInterval(checkTimer,15000);
Is there a way to achieve the goal of checking the time against the server time (via the php code) without refreshing the page? Thanks kindly! OK, I've just been working with kwyl, trying to intergrate a like/dislike script to her site. There was an original script, and although bugged, it's almost the What works The user clicks the like/dislike icon. Ajax sends a request to PHP: Either the like/dislike gets inserted into the database. OR, if the user has already liked/disliked that post, an alert error gets returned. What doesn't work If you click to like/dislike a post, it won't appear (the current count is in brackets beside the icons) unless the page is refreshed. How would I use this along side Ajax for auto update? $data = mysql_fetch_object(mysql_query('SELECT `like`,`unlike` FROM posts WHERE id="'.$row['id'].'"')); It's used he Code: $data = mysql_fetch_object(mysql_query('SELECT `like`,`unlike` FROM posts WHERE id="'.$row['id'].'"'));
?>
<br />
<div class="vote">
<a href="javascript:;" onclick="doAction('<?php echo $row['id']; ?>','unlike');">
<input type="image" name="submit" src="images/down.gif" /></a>
(<span id=""><?php echo $data->unlike;?></span>)
<a href="javascript:;" onclick="doAction('<?php echo $row['id']; ?>','like');">
<input type="image" name="submit" src="images/up.gif"></a>
(<span id=""><?php echo $data->like;?></span>)
I hate javascript and this is utterly driving me up the wall. Any help would be much appreciated. If you need more informaton/code please ask. Hi there How to send data from a text feild in GET method using an AJAX call... I already have codes working Code: to = "interfaces/add_department.jsp";
parm = "name="+name.value+
"&name2="+name2.value;
alert(parm)
post(to,parm,callBackFunctionForAddDepartment);
Here the variable name may have "me&you" or "me you" like that.... so how do i encode it so that it reaches properly? i'm doing the following on a select box to load the next select box (in a td with the id) if I look at the html returned by the ajax call I get PHP Code: <select name=optionvalue /><option value='test 1'>test 1</option><option value='test 2'>test 2</option><option value='test 3'>test 3</option></select> but it's showing as the select box and then test 1test 2test 3 my javascript code is PHP Code: function Loadoptionvalueselect() { //alert("here"); urltoajax = "getoptionsvaluesselect.asp?1=1" strarea = document.getElementById('optionid').value; urltoajax = urltoajax + '&optionid=' + strarea urltoajax = urltoajax + '&rnd=' + Math.round(Math.random() * 10000) // alert(urltoajax); $.ajax({ url: urltoajax, cache: false, success: function(html) { $("#troptionvalue").html(html); } }); } any ideas what could be causing this? 0 down vote favorite I have been struggling with this for some time.. I searched around but didnt get a solution yet. This is only an issue on production server. In my development environment, everything works just fine. I am using JQuery/Ajax to update product information based on product's Color attribute. for example, a product has A and B color, the price for color A is different from color B. When user choose different color, the price information is updated as well. What I did is to first add a javascript function: function updateProductVariant() { var myval = jQuery("#<%=colorDropDownList.ClientID%>").val(); jQuery.ajax({ type: "POST", url: "/Products.aspx/GetVariantInfoById", data: "{variantId:'" + myval + "'}", contentType: "application/json; charset=utf-8", dataType: "json", success: function (response) { var obj = jQuery.parseJSON(response.d); jQuery("#<%=lblStockAvailablity.ClientID%>").text(obj.StockMessage); jQuery(".price .productPrice").text(obj.CurrentPrice); jQuery(".price .oldProductPrice").text(obj.OldPrice); } }); } Then I can register the dropdown list's 'onclick' event point to function 'updateProductVariant' GetVariantInfoById is a Web method in the codebehind, its also very straightforward： [WebMethod] public static string GetVariantInfoById(string variantId) { int id = Convert.ToInt32(variantId); ProductVariant productVariant = IoC.Resolve<IProductService>().GetProductVariantById(id); string stockMessage = productVariant.FormatStockMessage(); StringBuilder oBuilder = new StringBuilder(); oBuilder.Append("{"); oBuilder.AppendFormat(@"""{0}"":""{1}"",", "StockMessage", stockMessage); oBuilder.AppendFormat(@"""{0}"":""{1}"",", "OldPrice", PriceHelper.FormatPrice(productVariant.OldPrice)); oBuilder.AppendFormat(@"""{0}"":""{1}""", "CurrentPrice", PriceHelper.FormatPrice(productVariant.Price)); oBuilder.Append("}"); return oBuilder.ToString(); } All these works fine on my local box, but if i upload to the production server, catching the traffic using fiddler, /Products.aspx/GetVariantInfoById becomes a 302 Object moved Object moved to here. On my local box, HTTP/1.1 200 OK Server: ASP.NET Development Server/10.0.0.0 Date: Thu, 03 Mar 2011 09:00:08 GMT X-AspNet-Version: 4.0.30319 Cache-Control: private, max-age=0 Content-Type: application/json; charset=utf-8 Content-Length: 117 Connection: Close But when deployed on the host, it becomes HTTP/1.1 302 Found Proxy-Connection: Keep-Alive Connection: Keep-Alive Content-Length: 186 Via: 1.1 ADV-TMG-01 Date: Thu, 03 Mar 2011 08:59:12 GMT Location: http://www.pocomaru.com/Products.asp...d/default.aspx Server: Microsoft-IIS/7.0 X-Powered-By: ASP.NET then of course, then it returns 500 error title>Unknown web method GetVariantInfoById/default.aspx. Parameter name: methodName Can someone please take a look? I think its some configuration in the production server which automatically redirects my webservice call to some other URL, but since the product server is out of my control, i am seeking a local fix for this. Thanks for the help! I've literally tried everything. Read 26 tutorials, interchanged code, etc. My validation functions all work. My AJAX functions work (tested manually using servlet URL's). The second servlet validates the reCaptcha form that's generated on my webpage. After the form is validated, even if everything's correct, nothing happens upon clicking submit. I even have an alert pop up if with the captcha result, just for middle-layer debugging purposes. I want to do all of my validation clientside; none serverside. However, going to be tough if I can't get my god damn form to submit. I've been puzzled by this for close to 36 hours straight. I can't see, and I'm going to get some rest and hope that there is some useful insight on my problem when I return. html form: Code: <form id="f1" name="form1" onsubmit="validate_form(this); return false;" action="register" method="post">

I have two password fields on a webpage form. If the passwords don't match, I want to display a message. I could use a popup, I could redirect to a page containing the message with another redirect back to the form or, the option I'd like to use, have a hidden table cell in the form containing the message that displays should the form be submitted without matching passwords. If I use the latter, where do I call the javascript function to display the hidden table cell? So in effect, only javascript function would execute if the passwords don't match, the action page itself shouldn't load at all. Can/should this be done on the action page?
plz i want to know how i can make a form validation using AJAX??? i need a sample or an idea of how making my form validation using AJAX thnx alot in advance Hi, I currently have a form which is submitted using a html submit button.

Thanks. ****ING FORUM PIECE OF ****, just wrote a whole post about my error and got taken to login when I clicked submit and the post is gone now, great, thanks for caching the tags and the title, really needed those...................flsdkjflsdkfjsd
This form retrieves results from a mysql database. It works fine but when I click submit it shows the result only for a second. When I hold down submit the result stays there. How do I get the result to stay on the screen after I hit submit? Even better how do I get it to spit out results without having to hit a submit button or press enter? Code: <html>

Hello all, I am building a service that other developers will use. As part of this, they need to embed a form on their website. This form will be hosted on my server, be updated periodically, etc. We'd been trying to create a Javascript file that would use JQuery to load the form, but we're running into issues from the Same Origin Policy, where Ajax requests cannot be made across different domains. Does anyone have an idea of how to fix this? We thought about using an iframe, but that solution will not suffice. Thanks! I am trying to perform an AJAX lookup during form validation onsubmit. It is important that it takes place during submit, but it seems to always return true and allow the form to post even when it should not. I have tried putting the AJAX portion in its own function and having it return true or false to the validation function but also does not seem to work. Here is what the code looks like... Code: $("#companyform").submit(function() {
$.ajaxSetup({ cache: false });
$.post("ajax_v2Functions.cfm", { coNum: $("#companyNumber").val() },
function(response) {
if(response != "") {
alert("That company number is already in use by " + response);
$("#companyNumber").focus();
return false;
}
return false;
} , "html");
if($("#companyname").val() == "") {
alert("The company name cannot be left blank.");
$("#companyname").focus();
return false;
}
if($("#companyNumber").val() == "") {
alert("The company number cannot be left blank.");
$("#companyNumber").focus();
return false;
}
});
Hi, I have a problem with sending data from a form to a php script with AJAX. To test if it works, I try to send data from the form, print it in the php with "echo", and then put it back in the initial html file. My Javascript code is: Code: function registerPrivateUser()
{
xmlhttp=GetXmlHttpObject();
if (xmlhttp==null)
{
alert ("Your browser does not support AJAX!");
return;
}
var postData="firstName="+ document.getElementById("txtFirstName").value;
var url="classes/users/checkRegistration.php";
xmlhttp.onreadystatechange=stateChanged;
xmlhttp.open("POST",url,true);
//xmlHttp.setRequestHeader("Content-Type", "application/x-www-form-urlencoded; charset=UTF-8");
xmlhttp.send(postData);
}
The function stateChanged, basically says: Code: if (xmlhttp.readyState==4)
{
var strResponse;
strResponse=xmlhttp.responseText;
alert('Response:' + xmlhttp.responseText);
}
checkRegistration.php looks like this: PHP Code: <? session_start(); $firstName=$_POST['firstName']; echo($firstName); ?> The problem is that the response is empty, but I don't know why. I have checked the input data and the postData variable says "firstName="+input (e.g. "firstName=Robert"), so that's not the error. I have read several forum posts here, but still haven't figured out what I'm doing wrong. If anyone could please tell me, I would appreciate it alot. 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. he everyone please i want to know how to submit a form using ajax every 5 minutes without reloading page i have a huge form for exams and i need to submit the form without the need to wait until pressing submit because the user may wait to think about the answer a very long time.. so i want to submit the form and at the same time i cant reload the page as it is in normal submit form.. so how i can submit form in the background without letting the user knows that the form is submitted??? |
