I am using getJSON to get results from a different domain and i wantedto get _some_ object back when calling getJSON so that i can insertsome variables into the callback scope.Basically, what i wanted to do was this:
var new_json = $.getJSON(url, function(data) {
alert
(this.variable_from_caller);
[code]....
I have this basic code following and its not returning anything at all. Even the alert is not alerting. I have checked and the select is sending the value fine But nothing happens on return. What i am missing?
$(function() {
below are my code
$.getJSON("http://mydomain.com/phptest.php?jsoncallback=?",function(data)
{
alert(data.a);
});
phptest.php echos out the following
{"a":"hello world"}
Yet, when i made the json calls(cross domain), it just return me nothing. However, under the same domain, I got the pop-up alert and return me the relevant data. But getJSON is suppose to be feasible across all domains irrespective of the same-origin policy.
I'm doing something with grails + jquery. My controller send a rendered json (which I know is sending correctly) but when the object "arrives" in the callback method it comes undefined. I can see it lenght, but not it's content.

I have a small piece of code:
$(":input").each(function(){
alert(this.name);
---->OK
[code]....
I am wondering how can I return the variable senttext from the function below?I have declared it and when I alert(senttext) below it appears as I want it but I need to return it and pass it to another function. When I change alert() to return the variable becomes undefined?
var senttext;
function getData()
{
if (window.XMLHttpRequest) {

None of my getElementById (or other) references produce anything but "undefined." This occurs in the latest versions of Fx, IE, Chrome, and Safari, so it must be something I am doing but not not seeing here. I have boiled it down to the following without success, and wonder whether there is some add on interaction. Fx 3.6.12 has the problem with this code:
<code>
<html>
<head>
<title>This is a test of getElementById</title>
</head>
<body>
<div id="area" name="area_name">xxx</div>
<script type="text/javascript">
var divs = document.getElementsByTagName('div');
var msg = '';
msg = 'Divs[0] contains ' + divs[0] + ' with width = ' + divs[0].width + "
";
msg +='Test area width by id = ' + document.getElementById('area').width + "
";
msg +='Test area width by name = ' + document.getElementsByName('area_name').width;
alert(msg);
</script>
</body>
</html>
</code>
I am working on a very simple code to determine the highest value from an array and also use parallel arrays.
The problem I am having is, when I try to invoke the parallel array namesArray it returns undefined.
I have coded the function so it can be used to find the highest value in more arrays as this is only the beginning of my code. Im not sure if this is what is causing the problems but I have a feeling it is code...
Here is a clip of code from a script project im working on. Now my document.getElementsByTagName is returning a "undefined" value.
<a href="[URL]" style="text-decoration: none; color: #EDDBAF; font-size: 16px;">
<center style="margin-left: 10px; margin-right: 10px;">
<font style="color: #EDDBAF; font-size: 16px;" id="title"></font>
</center></a>
<li id="name"><a http="[URL]" style="color: blue;">John Doe</a></li>
<script type="text/javascript">
var pname = document.getElementById('name').getElementsByTagName('a');
Now if I remove the ".getElementsByTagName('a')" it will actually work, but it also includes the <a> tag thats within the <li> tag, which I don't want.
document.getElementById('title').innerHTML=pname.innerHTML;
</script>
I have a following snippet

I could see the individual values in each index in firefox, but ie is displaying as undefined.
know whether this is not allowed in IE?. Is there any workaround for this?.
I have a function where in I call another function that assigns a value to a var. code...
For some reason my code below is returning 'undefined'. But when I place an alert(); before the 'return' it shows the correct value. However when I place an alert(); to show the var that is set to what the function returns it says 'undefined'.
Firebug throws no errors. I am using a little bit of jQuery.
I can not for the life of me get an ajax example/tutorial to work. I have tried dozens including prototype library and JQuery.
Here is my latest attempt:
As you can see I am trying to alert the variable teamH but I keep getting an undefined in the alert. I also tried a static drop down and I received the same undefined alert.
How I get that variable to contain my drop down choice?
Using jQuery v1.4.2, Firefox 3.6.6, Chrome 4.1, IE 6,7,8.
I'm using jQuery .css() function to get the value of the css attribute "background". The attribute has not previously been assigned a value (either in script or style sheet).
e.g. alert($(this).css("background"));
In Firefox and Chrome, the return value is an empty string (""). However in IE 6,7,8, the return value is "undefined".
It also makes the following statement impossible:
alert($(this).css("background").indexOf("somepic.gif"));
Because css() in IE doesn't return a blank string, doing indexOf() raises an error.
cross-browser scripting compatibility, for jQuery to return a blank string *for all browsers* if the css attribute isn't set. Otherwise we have to check for both "" or "undefined" which is the sort of pain jQuery users are trying to avoid.
in my javascript code I'm using a synchronous XMLHTTPRequest to periodically fetch a file from a server. Recently I added the "If-Modified-Since" header request (to reduce downloads if nothing is modified). Since adding the "If-Modified-Since" header request the javascript code still works with all browser (IE, FF, GC, AS) besides Opera.
The issue only happens if there is no new file to be downloaded: with the other browser I can see the 304 request status code, while with Opera (opening dragonfly) the request remains indefinitely as "in progress", the request status code returned being 0.
Trying to upgrade from JQuery 1.4.3 to 1.6.1. My getJSON queries no longer populate my SELECTs. The below code works perfectly in 1.4.3 but unsure what changes I need to make for 1.6.1.
function populateCause() {
$.getJSON(urlQueries, {sql:'list_causes'}, function(data) {
var select = $('#opencause');
var options = select.attr('options');
[Code]....
The ONLY change I made is sourcing JQuery 1.6.1 instead of 1.4.3. Evidently I need to change the method of parsing the JSON data also.
I am using the getJSON command and using firebug for debugging, if I go to this server i setup with this url: [URL] It returns json data warped with getdata({data}). I have validated the json part using jsonlint, so from firebug's net tab I get a param (callback getdata), header and response, etc. as expected. But if I use jquery's getjson, I get param, and header but the response is empty and function callback doesn't trigger (no alert). (I know that getjson uses OPTIONS instead of GETS and I can see that the request is made on the server and the json should be sent as normal).
Here is my code for this section:
<script type="application/javascript">
function getdata(data){
alert(data.name);

The problem I'm facing is as follows. I'm using a JSON call to checksome data before doing a JS redirect to a different page. The redirectworks but it's impossible to get back to the initial page using thebrowser's back button. The initial location is not being stored in thebrowser's history.This is the script simplified. If placed on[URL]browser's back button.

$('#click').click(function(){

After upgrading to jQuery 1.4.1 from jQuery 1.3.2, my getJSON requests fail.The error given to the ajax error handler, is "Invalid JSON: ..." where "..." is the text of the response.Firebug parses the JSON fine, and can display the JSON data as such in its console, and jQuery didn't have an issue with the same data with version 1.3.2.

But if I view the "contents" tab in httpfox I can actually see the data under <sourcetext> I require but there is an XML parse error.
<?xml-stylesheet
href="chrome://global/locale/intl.css" type="text/css"
?>
<parsererror>
[Code].....
The NS_ERROR_DOM_BAD_URI seems to be about cross domain issues but I'm working locally on the actual server so should I be able to access the data? Also why is there an XML parse error when I can see the exact data I want in httpfox's "Content" tab?
I have setup a little example here: [URL] It is JSONP because of cross site policy. The returned JSON is valid, you can check the response in firebug. The callback function is not fired.
Tested with jquery 1.3.2, 1.4.2 and 1.4.4. Same result.
Although i used getJSON in [url] i have not been able to connect with any of my own made up data. i tried 4, and the example at Flickr for "cats".
Only the latter worked... this is the output:
I am at that "base", as i did get the image there, but
[url]
[url]
[url]
[url]
Were all invisible==null!
How do i get "my" data into the page?
In jQuery 1.4.4 I could load a JSON file from subdomain2.website.com to subdomain1.website.com without any problems. When I upgraded to jQuery 1.5 this didn't work anymore.
Is this a jQuery bug
$.getJSON("http://subdomain2.website.com/resources/data.json", function( data ) {
console.log("data");
});
my $.getJSON method is not working, although $.get method works correctly.
I have posted my code here

I find jQuery very hard ..... if things don't work they just don't work quietly..
how to start debugging the code? how to get some error messages from jquery?
