Here is my server side code:
Here is my javascript:
When i call alert(data), it says it is "undefined". i am new to jQuery, but this appears to mean that no data is being passed to the callback function even though i know the $.post() executed properly (the server side code is executing, and the other alert() tells me that it had a successful result and the callback is being made.
I am new to all this but making good progress and having fun in the process. I have written quite a bit over recent weeks (including a few $.post / $.ajax calls) for various sites/applications but this one is really puzzling me. Here is a snippet of code that is causing me problems.
[Code]....
The problem is that execution jumps from line 2 to line 6 ... ignoring the function(data) and I am not sure why. I get the correct value of "team" arriving at the perl script .... and the perl writes the correct json back. I just can't think where else I need to look to debug this - as I said, I have done something similar 5-6 times over the last few weeks - all without a problem. So I am sure I am doing something stupid here.
I have the following in the header if index.php:
Code JavaScript:
<script type="text/javascript" src="/jquery/jqueryui/js/jquery-1.4.2.min.js"></script>
<script type="text/javascript" src="/jquery/jqueryui/js/jquery-ui-1.8.6.custom.min.js"></script>
<script type="text/javascript" src="/jquery/jqueryui/development-bundle/ui/jquery.ui.tabs.js"></script>
<script>

I then delete testFile.txt and click on 'Submit' without refreshing, and this time, it does NOT create testFile.txt - and hence, my guess is that it is not calling on functions.php, and of course, alert is empty as usual.
What I want to do is this: I want to be able to click on the Submit button - without refreshing the page - and return data from functions.php and display it within a div tag on index.php What am I doing wrong to get an empty alert?
I have an unordered list with each LI having an onclick event of "changeTabContent". When the page loads, I trigger the active LI's click. On a click, first thing I do is remove the previous results, which are a UL living under the "li.active" element. Next, I move the "active" class to the LI that was pushed and off the old one. Next, I add a loading animation to the screen. Next I append a new UL to the new "li.active" and use the load() method to insert a bunch of LI's from a different page. onSuccess, I remove the loading animation. [note 1] Next, you'll see a hack I added, more on that in a minute... Last two steps are to add a "more" link to the bottom of the returned li's, if a link was passed into the function, and finally I remove a handful of LI's (excluding more link) so there are only "x" on the screen.
My #1 problem is that the more link is not showing up at times, and the cleanList function is not removing LI's. I believe the problem is that with the load being async, sometimes those last two steps are being hit, but there is no LI's in the DOM yet. You can see I tried to run a hack so the while loop will execute when there is no "ul" yet. [note 1] - I tried to add the final two steps into the load() callback, but the LI's were NEVER loaded in the DOM when the callback function was executed.

I am trying to retrieve json data from the world bank's API, here's my code:
<html>
<head>
<script src="[URL]"></script>
<script type="text/javascript">
var theData;
$(document).ready(function(){
$("button").click(function(){
$.ajax({ url: '[URL]',
success: function(data) {
/*this alert message does not show*/
alert(data);
}, dataType: 'json' });
});
});
</script>
</head>
<body>
<p></p>
<button> Get World Bank Data </button>
</body>
The callback function is not executed but there is response when I checked it using firebug.
I am wondering why:
$.post("remote.php",
{'f':a_searchtype, 'partial':value},
function(data){
$("#result").html(data);
[Code].....
causes javascript errors in unrelated sections of code.
The second version can be used in a common routine that doesn't know what is being passed.
I've got an Ajax post that has been working fine with version 1.3.2 of jQuery, but when I tried it with version 1.4.2 it doesn't work. Specifically, the callback function is not firing when I define a variable equal to the function and then pass the post that variable.
Thus, in the following, if I call getCustList, the agent GetCustomerListSelection will run successfully on the server, but the ShowResult function will not fire. On the other hand, if I replace "ShowResult" in the post parameters with, say, "alert('You made it!')", then that works fine.

How can I check if the content type is JSON or HTML here (server can return any)?

I can't seem to get a variable declared from within a post callback, so that I could manipulate my script accordingly. I have delete.php, that deletes an id from a mysql db. If it fails, I want the script to stop and display the error. The .php script echos an "ok" if everything went fine, if not - it echos the error.var abort_error; // set the error variable
$.get("delete.php", { delete: $(this).parent().parent().parent().attr('id') },
function(data){
if(data != 'ok') {

I'm opening a new window with window.open() In the new window a file is loaded with the following post data function:
function ajaxPost(url,data){
$.post(url,data,

If I call this function form within the new window everything is fine
- If I call it from the opener window the callback function is broken
- only in safari - ff works fine.

Is there any was to prevent ampersand from splitting up the passed data? For example if my data looks like: "This is some text&blah blah" If I pass it as data it will get split up at "&": This is some text blah blah
View 5 Replies View RelatedI have some forms whose ID's are dynamically created via PHP by including a variable called "invno" as shown here:
<form name="formEditInvoice<?php echo $invno ?>" id="formEditInvoice<?php echo $invno ?>" method="post" action="javascript: SubmitEditedInvoice(<?php echo $invno ?>);" onsubmit="javascript: return ValidateForm(this);">
As you can see in the "action" attribute, I'm calling this function:
function SubmitEditedInvoice(invno) {
$.post('output.php?mode=6&invno=' + invno, $('#formEditInvoice' + invno).serialize(),
function(output){[code]....
The problem I'm having is that no data is passed to the PHP back end. I have verified that the variable invno is correctly passed to the javascript function, and have tested my .serialize() by using a hard-coded form ID, but I still get no data passed through.
The following function runs on form submit. The code appears to process correctly, the create.php file does it's job, but I'm directed to the create.php page and stay there, so the callback function never runs.. What do I have to change to get create.php to process 'behind the scene', and to stay on the original web page, instead of being redirected to create.php?

Since the massaged data are in the callback, they're not available at ***. I've tried declaring the variables outside the callback as shown, but this doesn't seem to work either. I'm thinking there must be an easier way. Is there?

how can I let the function that should check the message of the response know that 'msg' has been set?
at the end of the animation, I'm trying to run a function that relates to 'i', but every time it represents the last possible number instead of a range
for (var i = 0; i < bubbleArray.length; i++) {
var _this = bubbleArray[i]
var mLeft = parseInt($(_this.div).css('margin-left').split('px')[0]);

Is it possible to access the data arguments that are sent with the ajax function? Example:
$('#mycheckbox').click( function() {
$.get( '/ajax.php', { nr: this.id }, function( data, textStatus ) {
// Here I want to access the arguments I just sent with ajax.php
[Code]....
I could easily do $('#mycheckbox').attr('checked', 'checked'); but that is not what I want. Also I don't want to send the arguments with the response. Anyone knows a solution? I can't find it in the documentation of jQuery and not in the discussions here.
I have Javascript code that looks like this:
var data1;
$.post('save_search.php', formData, function(data) {
data1 = data;
});
jsonData = eval('(' + data1 + ')');
if (jsonData.return_status.search("successful") > -1)
$('#msg_div').html("<font color=red>Search was saved</font>");
else
$('#msg_div').html("<font color=red>Search was not saved. Try saving again.</font>");
"data1" comes up as undefined in the statement
jsonData = eval('(' + data1 + ')');
Even though "data" is a perfectly correct JSON string *inside* the callback function! I can put the eval statement inside the callback function and it will form a good JSON object, like this:
jsonData = eval('(' + data + ')');
I'm simply trying to get my Ajax response data to the outside of my callback function so I can use it in other Javascript code. I've never seen an ordinary function behave this way.
Inside of a page, there is a iFrame, which houses WYSIWYG editor.I'm trying to pass data (passedString: html, inline css, text ...) to a popup.When I pass same string to same div with id="idx" located on a page, where iFrame is located, it receives it without problems.Problem appears, when I try to pass string to popup.
