JQuery :: Ajax Returned Data Format ?
Sep 23, 2009
Getting information from a php file. Basically :
MY JAVASCRIPT FILE:
In this dumb example, I'm unable to match the 'data' returned variable with the value I assigned to it in php (I can't manage to enter my 'do stuff'), yet its value is 'ok' if I display it. I have no problem to retrieve html code from php and inject it in my pages, but I can't test it as a regular javascript string.
What's wrong in this ? What have I missed about the 'data' format ? Do I have to 'cast' data to a javascript string (and if so, how ?)

I would like to get get some data which format is "XML" and it is returned from an API. However, the $.ajax() doesn't work in this case? But the same code works when the "XML format" data is from an XML file. Can anyone tell me why?

$.ajax({
So I'm loading the div#my_events by prepend(data) where "data" is another well styled div. Is there anyway to animate this returned data. Unfortunately I can't just specify a unique ID on the incoming data. So I was wondering how else I might be able to address this data I'm returning.
It is basically a topic list, with a modal that sends jquery to add a topic to the database, and returns the topic from the database, hides the modal, and displays the last added topic at the top of the topic list. Now I'd like it to do something slightly fancy like animate the color of the background to bring the user's attention to it.

I am currently using $.ajax to post to a Perl file that queries a webservice and returns XML. Running the Perl via command line confirms that XML is being returned with Content-Type: application/xml. However, regardless if I set the dataType parameter to "xml", "XML" or just use jQuery's intelligent guess, it appears that I am not getting any data returned to my function at all.
I've tried using the full $.ajax notation and the simplified $.get notation as follows:
and:
I have also tried using JQuery to perform a "GET" directly to the webservice which returns XML by default and still I get no data returned to my function.
Although I doubt it's browser-related, I have confirmed this in both Chrome (5.0.375) and Firefox (3.6.3).

I'm currently working on a form where an entire HTML page is returned via the .ajax method. I would like to display only the content of the div with the id "content" (of the page returned) in the div with the id "result" (in the calling page). Here is my current script :

I'm having a little problem with a jQuery/JS script I just wrote in IE7/8. The problem is the first 2 lines of the returned data are not being displayed (w or wo styling) but only in IE. The strange thing is though if I alert the returned data it's there.
The code can be found at [url]

Is Json considered the better file format for loadind data via Jquery AJAX? I am going to use it either way, but from a cutting edge stand point, is JSON looked at a more cutting edge since it loads faster. 2. And for that matter is anyone using css3 and E4X? All these seem to require the latest versions of all browsers. Since my goal is to be cutting edge I was thinking to do some stuff in the above listed that require only the latest browser if it is detected, if not use what works in most all browsers? What are cutting edge web app developers really doing at this time?

I am doing a few tests with javascript and oop. but one failed so i falled back to the way i usually do this but it still isnt working properly. i am using $.post() but instead of returning whatever is echoed in the php file like it does with all my other scripts it returns the content of the file:
Isnt returned in var data but the whole file is returned as a string.

Here is the code I am running:
The url is a very straightforward servlet that queries a database and returns either Y or N. That part is working fine. The first alert shows Y or N just as it is supposed to.
However, the second alert is always showing Turbo, as though the if statement is not able to compare properly. This is probably javascript rather than specific to jQuery, but can anyone see where I'm going wrong?

Here is what I'm trying to do. I will pass a directory to a PHP script, that script will then return an array of filenames back to the javascript that called it. In the javascript I want to take the filenames returned and create links to them in an unordered list.
The PHP code to get the filenames is done and when I run the script I get an array that I have formatted into json... an example of the encoded array is as follows...
{"filename:["file01.jpg","file02.jpg","file03.jpg","file04.jpg","file05.jpg","file06.jpg"]};
So here is the jquery I'm trying to use to get the filenames and create my links... But I must be missing something because my variable... data ... is empty... but status is Success.

When I use the ajax function to grab the remote content of some page, I would like to then apply jQuery selectors to that data. Does anyone know how this can be done? Let's say that I just grabbed the content from an html page. I would then like to be able to use a standard: $("#someID").val() to get the content of that page element.

I have the following javascript:
<script type="text/javascript">
$(document).ready(function(){
// autocomplete setup
[code]....
The autocomplete (I'm using this one) and the getJSON work perfectly. The problem comes when I try to do something with the returned json data. Line 14 won't work for me. Any selectors I try on the returned json data won't work. The selectors still work on items that were there before the json data was returned.

I am trying to build a table from backend data and then perform a filter on it using the picnet table filter. After much messing about I have discovered that the problem lies with the table data returned from the server. As a test, all I want to do is get jQuery to make an alert when a table cell is clicked. I added a hard coded table cell at the beginning of the table and when I clicked on it, the alert appeared. However, clicking on any other cell had no effect.

I am developing a web application in java (jsp's and servlets). For the project I am working on I will need to develop an html data entry screen and the code to load data into the screen, and then save the data back to the back-end database.
How to do the following:
Read the data out of the database (JDBC, no problem) in a servlet.
Put the data into the appropriate form for returning to the data entry screen, which will be a jsp. (Is JSON the right choice for passing the data from the servlet to the jsp?)
In the jsp, parse the returned data and populate the HTML form elements (text fields and combo boxes). When a button is clicked, pull the data out of the form elements and return to a servlet for saving back in the database.

I have a html form which produces 3 post varaibles.
I'd link to be able to call a php file when sumbitted that sends the data from my form and returns the results from my php file to a div on the oringal page.
I know that you can use .load to call a page to be diaplayed within a div $('#container').load('url #div_on_page') but dont know how to send the from data.
this is the code.
<form method="post" id="new_user_form" >
<input type="text" name="newuser" />
<br /><br />
<input type="password" name="newpassword1" />

I'm pretty new to jQuery and I'm using $.getJSON to submit some data to a PHP script which either returns 5 sets of json-formatted data or data to indicate an error condition (i.e., no data available) from the PHP database query. The callback routine handles the 5 sets of json-formatted data just fine (using $.each...) but I'm having trouble testing for either just a string with 'null' in it or a json-formatted data return of [{"error":"null"}].
My callback code for the second approach looks like this:
function handle_stores(data) {
if (data.error == "null") .....
But this test does not execute the following code for the 'true' condition, i.e., data.error == "null" never evaluates to 'true'.

I define a "click" event on "a" tags in the ready part of a page. It fires just fine when I click on any "a" tag on the page. I then have a button which sets the content of a div using ajax. This content contains a couple of "a" tags. The issue now is that the "click" event does NOT fire when clicking on these tags. I suspect it is because they did not exist when the page was initially rendered. What is the "JQuery way" of dealing with an issue like this? Of course I cannot be the only one in the world who needs to return HTML with events from my ajax calls :-)

I have a button that do appear on my page through a post with jquery:
$.post(
'more_item.php',{
NumItem: NumeroItem,
Str : $("#form-itens").serialize()
[code]....
but this has not worked. the latter showed that jquery is inserted in the index. the main page that calls the button. jquery in a home can act on an ID loaded from another file with ajax?
