JQuery :: $.post Callback Data Is Empty

Nov 10, 2010

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>

[Code]...

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?

JQuery :: $.post() Callback Executed No Data Passed

Jun 24, 2009

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.

JQuery :: Post CallBack Not Firing In 1.4.2?

Apr 20, 2010

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.

????
//////////////////////////////////////////////////////////////////////////////////////////////////////
// Define return function for AJAX
var ShowResult = function(result) {

JQuery :: Passing A Variable From A Post Callback Function?

Oct 23, 2010

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') {

$.post Not Sure If Callback Is Set Up Right

Oct 17, 2009

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?

JQuery :: Access Data Outside Ajax Callback?

Apr 2, 2011

The answer to my question is probably very simple, but I'm having trouble making this work.

I want to access a local csv file, rearrange it into an array, and use the data later in my script. The logic of this in psuedocode is [code]...

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?

JQuery :: Ajax - Access Data Arguments In Callback?

Sep 17, 2009

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.

JQuery :: How To Get Ajax Response Data To Outside Callback Function

Aug 19, 2009

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.

JQuery :: Can't Get Load() To POST Data

Jul 30, 2010

I'm a total JS/jQuery newbie, and I'm having a problem using jQuery's load() to POST data to a remote PHP script and rewrite a DIV with whatever the server sent back.

Using a proxy in between, I can see that the JS script isn't sending anything, so I guess there's something wrong in the JS code I send to the browser [code]...

Populating Mysql Data To Empty Selectlist

Dec 8, 2003

I'm trying to dynamically retrieve data from database and stuff all these data into an empty select list thru javascript. But I can't get it to work


PHP Code:

while( $row = mysql_fetch_array( $sql ) )
{
$getChildren .= 'var newCElem = document.createElement("OPTION");'
$getChildren .= 'newCElem.value = "' . $row['id'] . '";'
$getChildren .= 'newCElem.text= "' . $row['label'] . '";'
$getChildren .= 'allPaths.add(newCElem);'
}


$getChildren will be spit out to my javascript code part where I've place <%getChildren%>. When I try to manually type in the output into the javascript code, it works but not when dynamically.

JQuery :: Function(data) Not Being Executed After $.post

Mar 22, 2010

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.

JQuery :: Use .each() And Send Array As Post Data?

May 11, 2011

The script below works, but only returns one headline/url from the html list.I am coming from a procedural background and know there must be a better way to pass all the urls and headlines (the link text) to my PHP script, which populates my database, but even after reading 'Jquery in Action' I am flummoxed.how to attack this problem? The .each portion of my script does not seem to work as I expect it to. I have also tried append, which would seem to be a solution ... really all I need is the "which" value from the url, so passing a simple array of those values to PHP would suffice.
