May 26, 2010
Im trying to validate a form (easy) and POST it to a third party WCF service. I am able to validate and POST data to the service, but its returned data (in table format) keeps opening in a blank page with their url in the browser address bar. Can't have that, I need to grab the returned data and .append it to a div on my page. Here is what I have that FAILS
<script type="text/javascript">
$(document).click(function() {
//cancel form
[code]....

I'm building a web app that provides music information (i.e. info on artists, albums, songs, etc.) and for the info source I'm using the MusicBrainz API.
Now, I'm trying to load the data from an API call and process it, with jQuery.
This is the code I'm using:
With 'queryString' being the URL string for the request, and then I'd proceed to read the data out of the 'xml' object. Fairly simple.
However, this is where problems arise. The code works flawlessly when running locally on my computer, but does not work at all when I upload everything to my web server and try to run it there. I did some reading and have discovered that AJAX calls can't be made across different domains, due to security issues.
So I've read through numerous solutions, but almost all require either something with PHP (which I have absolutely NO knowledge of) or grabbing the data in JSON format (which apparently isn't subject to the same security restrictions). However, my main problem is that the MusicBrainz API does not return data in JSON format (in fact the only format it returns is XML).

I am doing some development using jQuery $.getJson lately and found the following weird scenario.
1. open google chrome without any argument then load a local html file.
2. the local html file will need to have $.getJson[url] .... bla bla bla and jQuery.support.cors = true.
3. data will get loaded
But if you try to load the exact same json data from other domain or localhost, it wouldn't works.

I have some DIV elements having some ID and content in it .. for example
I have submit button when I click this ... I should generate a JSON data structure like this
I need to POST this on submit button clicking.... I have seen some serializeArray() function but it works well for form based elements, I have created some string based structure in which I am printing the single quotes and double quotes like this fashion by creating a array and pushing itvar result = new Array();
Is there any short cut to create JSON with this datas ...

I use $.post like so: $.post("http://mydomain.com/some/webservice", $.toJSON({ emailAddress: emailAddress }), callback, "json"); this works great..the response of the POST is a json string and that is used in the callback..now I added https: $.post("https://mydomain.com/some/webservice", $.toJSON ({ emailAddress: emailAddress }), callback, "json"); so it is now a cross domain post...in firebug I see that instead of POST'ing like in the http case..it first is sending an OPTIONS verb..why? The webservice doesn't know how to respond to that and gives a 403 forbidden...I need it to just send the POST like it did when it was on the same domain...

I am using .ajax() to access cross-domain data using JSONP. Because I need to be able to cache the data I want to use a static name for thejsonpCallback function, so I have set the jsonpCallback option in the .ajax() request. However that appears to requires a global function whereas the auto generated function didn't (well maybe it did but that was all hidden from me).
I definitely need to be able to cache the results. Ideally I wouldn't have a global function handling the data. Is there another way to do this? If not what is the best practice way to go about using a global function these days and how do I provide it with the context of the object/module it was called from - which is where the data is needed?

The below code posts a couple of vars to a php file which sends back a json object containing (in the test case) one object called 'faves' with 2 variables (let's say called var1 and var2). I can't seem to access the variables after the ajax call. The result is always an 'undefined' error message. I've tried:
console.log(data.var1)console.log(data.faves.var1)
console.log(var1)
All to no avail. Can anyone tell me what I'm doing wrong here? I have checked with FireBug that all the data returned is good and well-formed etc.
$(function() {
$.post("<? echo base_url(); ?>test.php", {
id: "<?php echo $id; ?>",
[code]....

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 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 got this working in FireFox if I changed headers to Access-Control-Allow-Origin: * With IE7 I'm getting "Access is denied" error. And with IE7 I can't use XDomainRequest.Is there some workaround besides creating proxy? Like using another request method(PUT?)?

im sure this will be pretty simple, at the moment i have some code which sends text from a textarea to a php file, the php file then stores the data into a database.the javascript post is as follows:
var text = document.getElementById(area).value;
http.open('post', 'autosave.php?text='+text);
there is a little bit more to this(just a handle response).My issue is that when the data is passed through javascript newlines and breaks disappear, so when i call the saved data it is presented as one long string with no formatting.i tried the nl2br() function and htmlspecialchars() function in the php file that the javascript passes the data to, this made no difference. I then tried to replace /n with <br /> in the javascript before passing the text variable again this made no differnce.

I'm writing a web page, which should interact with pages on another server using an iFrame. I want to use a form on the parent page to post to the URL on the iFrame and capture the response, without reloading the parent page.
Here are the details:I have a FORM on the parent JSP page, with some session data in hidden fields. The point to note is that the whole session data is on the client side, in encrypted form. This data should be posted to the server for each request, synchronous or asynchronous.Now, I need to call an application on a server on a different domain. For this purpose, I am using an iFrame. The session data in the parent page should also be passed to the application in the iFrame.

Is there any way to resize an iframe dynamically to the height of its content that works cross browser and works when the iframe content is on another domain than the main page (I have access to both pages, so code can be put in either) Also, it must resize when links in the iframe are clicked (ie when a new page within the iframe is loaded)

I'm fairly new to javascript and JQuery so please bear with me. I've written a simple app using JQuery whose purpose is to select the fastest mirror site. To this end I use several $.ajax calls - one to each mirror site -and I don't do anything with the data I get from these, I only use the order in which they respond to sort the sites from fastest to slowest. I'd share the code, but really the only thing it does is call the $.ajax function and append a line in a table using the success: callback. This works perfectly fine for most browsers, except IE which throws the 'access is denied' error. I know about cross domain restrictions and understand the reasoning behind - my plan was to put my script in the 'trusted' zone and enable the required options to bypass the problem as this will be used in a controlled environment, but no matter what I try my code won't run in IE. Some of my mirror sites are indeed in a different domain. What I have trouble understanding is why all other browsers (FF, Chrome etc), with their default configuration, allow my code to run flawlessly? If the reasoning behind IE blocking this is correct, then why do others allow it?
Also obviously for my purpose using a server-side proxy makes no sense as I want to test the sites from the client side, not from the server. I've also read about other work arounds such as JSONP but unfortunately the sites that I'm testing cannot support this. But once again, what I'm really wondering about is why my code works flawlessly in other browsers..

I need to send XML / XML string to a web service cross domain.I have a JavaScript function that creates the XML by selecting the fields on the page and formatting the values into the required XML document. The HTML page is running on the users local machine but need to send the XML to a public secure (SSL) web service (ASMX) that has one argument of type string.I have tried to come up with a solution and the only one that is currently working is JSONP with GET. But this results in the data being send as part of the query string and is in clear view, thus beingintercept-able.
