Why function aSuccess don't work
<?php
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 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.
On a project I got stuck on this "problem". When you make a json (ajax) call. You also need a callback function. Which means I have to call the next $.getJSON within that callback function to read the next portion of data. In my opinion this is not very readable code...What I want is a nice and readable piece of code. Where you could just write it like this:
var data1 = $.getJSON(..);
var data2 =$.getJSON(..);
I've found a solution here: [URL] (explains my problem perfectly). But it's not compatible with the getJSON story. Is there already a possibility to do this with the jquery library?
I have been trying to figure this out for a few days now and have finally come to the point where I think I got it but may just need a little push to get what I want.
Heres the situation:
I have this function that uses ajax to access a database and returns the results in the responseText. That part is working fine, I have confirmed that the responseText contains the information that I need
**************code*****************************************
//new ajax already created and assigned to the variable xmlhttp//
var response_recieved = "some data";
function get_answer(Table_Name, Field_Name, Data_Type) {
[Code]....
As evidence by my posting, this is not working correctly. The variable response_recieved is coming up undefined outside of the callback function assigned to the onreadystatechangeproperty.
Based on the information that I have gathered online from various forums, I believe this issue has to deal with a problem with closure in the callback function assigned to onreadystatechange property. I don't think it has any. Based on the fact that there is no anonymous function in that function. But my problem is that the call back function is anonymous itself... I think???
get the variable response_recieved to survive outside of this function.
I'm sure that "insert.php" works because I've tried the
<form method="POST" target="insert.php">
And it adds to the database through "insert.php". But when I remove the
'method="POST" target="insert.php"'
And replace it with $.ajax() it won't work.
Here's the code:
$(document).ready(function(){
$("#submit_wall").submit(function() {
var message_wall = $('#message_wall').attr('value');
var message_wall = message_wall.replace(/</g, '<');
var message_wall = message_wall.replace(/>/g, '>');
var message_wall = message_wall.replace(/<.*?>/g, '');
var FeedUNum = $('#FeedUNum').attr('value');
var FeedConn = $('#FeedConn').attr('value');
$.ajax({
type: "POST",
url: "insert.php",
data: "FeedUnum="+FeedUNum+"&message_wall="+message_wall+"&FeedConn="+FeedConn,
success: function(){
$("ul#wall").prepend('<li style="display: none;">'+message_wall+'</li>');
$("ul#wall li:first").fadeIn();
}});
return false;
});});
The animation works, but the callback function (alert) doesn't get called.[code]
View 2 Replies View Relatedi downloaded a slideshow script called galleria. problem is when it loads, my header image, which i have sliding in, gets really choppy. so, i want the galleria script to execute after the header animation
is done. i haven't been able to get anything to work, including attempting callback, hacks, and settimeout. here's my current code, which does not delay the beginning of the galleria script. what am i doing wrong, very curious?
[Code]...
This is my code:
I've set the animation to large numbers (1000) to make it very obvious.
The helper will show before the other fieldSets have been hidden. The show animation begins about half way through the hide animation. Since both elements are occupying the same space, this makes the container jump around in size as it breifly expands to fit one under the other.
how can i write a function that accepts a callback function?[URL].. i want myFunction to load some data via(an unordored list actually) load method end then somehow to return the wrapped elements for the callback function, exactly like load() does.

today I updated my Firefox from 3.5 to 4.0b3 and it seems that the AJAX success callback is not longer fired. Firebug shows the correct response but the function is never called. Is this a Problem of the FF Beta, or is Jquery responsible for this?
Here is my Script
$.ajax({
url: 'ajax.php',
success: function(data) {
console.log('success');

currently using jq 1.4.2
And i have gone through this forum and other forums for a simple fix ... since so many have had this problem..but i have nt found anything that seems to work hence i am posting this problem
$(".editvolunteer").fancybox({
'width' : 970,
'height' : 460,
'autoScale' : false,
[Code]....
I dont know what i am doign wrong i have used debugbar and i can seethe html content that comes back i have used fiddler and i see hte html content that comes back there....the xhr stat =200 so every thing is good..yet it doesnot replace the the content $("#updateroster").html(data).
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?

how can I let the function that should check the message of the response know that 'msg' has been set?
What I noticed is that my error callback is fired every time.
MyService.asmx:
[WebMethod]
public FileInfo[] GetFileInfo(int Id){
Proxies.ServiceRef.ServiceClient c = new Proxies.ServiceRef.ServiceClient();
return c.GetFileInfo(Id).ToArray();
}
The Jquery code where I am getting error:
$.ajax({
url: url,
data: jsonData,
type: "POST",
contentType: _I.contentType,
timeout: _I.timeout,
dataType: "serviceproxy", // custom type to avoid double parse
dataFilter: function (jsonString, type) { .....
When I debug using firebug the response is as follows.
{"d":[{"__type":"Proxies.AFARServiceRef.AssignmentInfo","ExtensionData":
{},"AssignDate":"/Date(1317748587667)

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 a web page that has a few text boxes, and a dual list control. All of these data elements are for a particular entity. The form is for creating a new instance of this entity and saving it to the database. The dual list shows available people to use, and the user can move options from the available list to the selected list. All of this works perfectly when posted. There is a button at the bottom of the page to post the form.
To make things easy, I also want to include a hidden "form" that lets the user add a new person to the dual list without leaving the page. They click an "Add New" link which shows a previously hidden div. In the div are two text boxes: "emailName" and "emailAddress", and a button to click called "Add".
When the user clicks the "Add" button I need to validate the emailName and emailAddress fields, and only those two fields. If they are valid then I will make my AJAX request and handle the return data by adding a new option to the dual list.
I would like to achieve such thing, as to load some part of other page, like this:
$("#content").load("example.com/main.htm #content > div");
but I need to do a beforeSend callback, to fade out the current content, wait until it is fully hidden, and only then fade in with the received ajax request. But doing this, for example, with .ajaxSend, the content loads much quicker, then fadeOut is complete.
I'm trying to do some animation designs. Basically where I'm stuck is I have a bunch of things I want to do, but not until the duration of the switchClass method is complete. Looking at the UI documentation site, there doesn't appear to be a callback ability. how I can make a callback on the switchClass?

It works smoothly, But when I use this in a callback function it doesn't work as follow;

I think that in jQuery 1.6 the callback function is failing in IE(8).I've reverted back to jq1.4 and all is okay. Sample code that fails in 1.6 for IE
8;$('#add_edit_contact_content').load('company/ajax/dsp_addEditContactContent.cfm', function(){
alert('loaded');
});
The error reported is; Message: Could not complete the operation due to error
