How to get the blackberry uuid using javascript and web works

I am trying to find the device UUID using javascript with web works for devices with OS 7 and less.
The code I am using:
function getIdentityData(){
$.ajax({
type: "get",
url: "http://localhost:8472/blackberry/identity/get",
success: function(msg){
alert(msg);
}
});
}
as found in their documentation is not working, I never get the alert? https://developer.blackberry.com/html5/apis/blackberry.identity.phone.html
I have the following in my config file
<rim:permit>read_device_identifying_information</rim:permit>
<feature id="blackberry.identity.phone" />

Have you tried just blackberry.identity.PIN as documented here - https://developer.blackberry.com/html5/apis/blackberry.identity.html#.PIN

$.ajax async:false doesn't work in IE and Firefox, works in Chrome/Safari

I am trying to measure download speed with ajax call.
Here is the my code
var start = new Date();
$.ajax ({
url: 'https://www.example.com/perftest/dummyFile1024',
cache: false,
success : function() {
var total = (new Date() - start)
alert(total)
},
error : function(jqxhr, status, ex) {}
})
It doesn't wait until whole file loaded. When I add async: false, it waits for loading whole file and I am able to measure bandwidth at chrome and safari however internet explorer and firefox still works the same as async: true, they don't wait until whole file loaded. Do you have any idea how I can manage it works for I.E. and firefox as well? Thanks.

IE 8/9 cross domain requests require jQuery to use a different transport method which uses a XDomainRequest instead of the default XmlHttpRequest.
I believe the question has been answered already here: [question]: CORS with jQuery and XDomainRequest in IE8/9
For FireFox try setting the "dataType" of the content returned by the $.ajax request.

Google Chrome - Failed GET ajax request

I am developing a website which loads html from a template page then loads content from XML. for instance these are called in the document.ready function
$.ajax({
type : "GET",
url : "template.html",
dataType : "html",
success : function(html) {
var ndoc = document.createElement('html');
ndoc.innerHTML = html;
page = $('body', ndoc);
$('body').html(page.html());
$.ajax({
type : "GET",
url : "XML/content.xml",
dataType : "xml",
success : function(xml) {
page = $(xml).find('chisiamo').find('dialogue')[0];
setupPage(page);
}
});
}
});
This works well in Firefox and Safari. But in Chrome i get a 'Origin null is not allowed by Access-Control-Allow-Origin' when it tries to load template.html. How can I solve this problem? thank you very much.

Try to start Google Chrome with this arguments :
google-chrome --disable-web-security --allow-file-access-from-files

You should be able to create a Chrome Web App and set the permissions in the manifest to allow it access to read files from the file:// scheme.
http://code.google.com/chrome/extensions/manifest.html

You have to add permissions to the page you are requesting in the manifest. Also try using $.getJSON instead ;)

Access denied to jQuery script on IE

I have an iframe using the jQuery 1.4.2 script. The same iframe is injected into both http and https sites. The jQuery script is included in the main HTML file as a relative path (e.g., /scripts/jquery-1.4.2.min.js).
When an AJAX call is made, Internet Explorer denies access. The AJAX is calling on another subdomain, but it's using the right protocol. All other browsers work but Internet Explorer gives the following error:
SCRIPT5: Access is denied.
jquery-1.4.2.min.js, line 127 character 344
I heard this error is from cross-domain AJAX calls. But why is IE the only one giving me crap? Is there an IE solution?
Also, this is my AJAX:
$.ajax({
url: thisURL,
dataType: "json",
data: {cmd : 'getMessage', uurl: urlVar, t: Math.random()},
success: function(ret){
callback(ret)
}
});

IE requires you to use XDomainRequest instead of XHR for cross site, you can try something like...
if ($.browser.msie && window.XDomainRequest) {
// Use Microsoft XDR
var xdr = new XDomainRequest();
xdr.open("get", url);
xdr.onload = function() {
// XDomainRequest doesn't provide responseXml, so if you need it:
var dom = new ActiveXObject("Microsoft.XMLDOM");
dom.async = false;
dom.loadXML(xdr.responseText);
};
xdr.send();
} else {
// your ajax request here
$$.ajax({
url: thisURL,
dataType: "json",
data: {cmd : 'getMessage', uurl: urlVar, t: Math.random()},
success: function(ret){
callback(ret)
}
});
}
Reference
http://forum.jquery.com/topic/cross-domain-ajax-and-ie
not sure whether it fits your scenario
xdr = new XDomainRequest();
xdr.onload=function()
{
alert(xdr.responseText);
}
xdr.open("GET", thisUrl); //thisURl ->your cross domain request URL
//pass your data here
xdr.send([data]);
you can find some more guidance here

This solved the issue gracefully for me:

Just install/compile after jQuery and before your script and use the $.ajax method as you normally would, the rest is handled behind the automatically.

Have you try to use the lastest of JQuery(> jquery-1.8.0)? Since the version 1.8.0, they solved some IE9's bugs. Perhaps this one too.

I had a similar problem and the solution for me was to use jsonp instead of json. That way I didn't have to break out a customer version for IE.
You can only do this if the json server host supports the callback request variable or you have access to the server and can add support. Here is a page that helped me understand the process. Its .net mvc focused, but it gives a good over view of the diffrence between json and jsonp.

Check the domain you are accessing, following response headers should be there
"Access-Control-Allow-Methods" : "POST, GET, OPTIONS"
"Access-Control-Allow-Origin" : "http://www.mydomain.com" or "*"
the other domain should allow your script request. One more header to be added to your response is P3P header.
"p3p" : "CP=IDC DSP COR ADM DEVi TAIi PSA PSD IVAi IVDi CONi HIS OUR IND CNT"
it should help you out.

I was facing similar issue.
I was using file upload control but it was hidden and I had another element trying to control the file upload and events to upload file in ajax way
try using the file upload control directly. this solved issue in my application.

I get this bug (and thus google here) but the reason was very different. So if you don't have cross site and still get this access denied error: double check the value sent
let's say that you affect one of you variable with the bad following expression:
urlVar = $("theID").val // without () this was the error!
[...]ajax call:
data: {cmd : 'getMessage', uurl: urlVar, t: Math.random()},
Google/FF have no problem with this (check what is receive server side...) BUT IE refuse to send this!

I changed my JQuery from version 1.10.1 to 1.10.2 and it seems to have solved this problem for me.

It seems that MS is finding its own way of doing things, rather than adopting industry recommendations. I found the solution here:
https://github.com/MoonScript/jQuery-ajaxTransport-XDomainRequest/blob/master/jQuery.XDomainRequest.js

Simply add 'callback=?' on your ajax URL request like here:

Jquery ajax() call fails in IE8

I have the following code for submitting data using ajax from forms of class ajax. this works perfectly in Firefox, Safari and Chrome but fails in IE.
ajax: function() {
$('form.ajax').live('submit', function() {
var form_ajax = $(this);
$.ajax({
url: form_ajax.attr('action'),
data: form_ajax.serialize(),
type: form_ajax.attr('method'),
dataType: 'script',
beforeSend: function(xhr) {
$('#ajax-bid-new .ajax-form-error, #ajax-bid-new .ajax-form-success').remove();
form_ajax.slideUp();
}
});
return false;
});
Please help - I am stuck here for past 2 days. I am returning a Javascript file from server to be evaluated inside browser. This works as expected in Firefox, Chrome and Safari, but IE receives it as a file and opens up the file download dialog.
What can I do in IE to make this work? I tried by dropping the following code in my application.js file (I'm doing a rails project btw)
// public/javascripts/application.js
jQuery.ajaxSetup({
'beforeSend': function(xhr) {xhr.setRequestHeader("Accept", "text/javascript")}
})
I get the same behavior from IE even after writing the ajaxSetup block like above.

Looks like live doesn't work with submit in IE. Have you tried using a normal submit instead:
$('form.ajax').submit(function() {

To catch live form submit events in IE, instead of:
$("form").live("submit", function() { ... });
to
var submitHandler = function() { ... };
$("body").children().each(function() {
$("form", this).live("submit", submitHandler);
})
Point to be noted
IE caches AJAX requests really aggressively (more so than Firefox, anyway). You need to set the Cache-Control headers in the response appropriately if this is not right for your site.
change your content type, last time i fixed similar problem by changing content-type from application/json; charset=utf8 to just plain application/json
jQueries' bind and live behaviours along with the liveQuery plugin

LiveQuery plugin solved the problem http://github.com/brandonaaron/livequery
