I tested this on Windows Mobile 7.

After LOTS of time spent to understand, I finally found this:

The Solution is simple, just set this:

<pre><code>$.support.cors = true;
</code></pre>

and Ajax cross domain requests will work!

blocks|key|657747|text|jQuery.support.cors+=+true;

$.ajax({
++crossDomain:+true,
++url:+"",
++type:+"POST",
++dataType:+"xml",
++data:+soapMessage,
});|type|code-block|depth|inlineStyleRanges|entityRanges|data|syntax|javascript|657748|您需要将跨域的值设置为true|unstyled|657749|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$B|C]]|$1|D|3|E|5|F|7|J|8|@]|9|@]|A|$]]|$1|G|3|-4|5|F|7|K|8|@]|9|@]|A|$]]]|H|$]]

<pre><code>jQuery.support.cors = true;

$.ajax({
 crossDomain: true,
 url: "",
 type: "POST",
 dataType: "xml",
 data: soapMessage,
});
</code></pre>

you need to make the cross domain value to true

blocks|key|443454|text|这个问题已经困扰我一段时间了。作为一种变通方法，我使用位于同一站点上的代理脚本。这样的脚本只是执行服务器到服务器的非ajax+HTTP请求(想想curl和WinHttp.WinHttpRequest)，并将状态和数据传回调用者。它可以工作，但显然效率不是很高，因为它必须执行两个HTTP请求。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|443455|在我的例子中，解决方案是上面描述的所有内容加上“Access-Control-Allow-Origin”头的组合。|443456|$.support.cors+=+true;+//+this+must+precede+$.ajax({})+configuration

This problem has been bugging me for some time. As a workaround I use proxy scripts located on the same site. Such scripts simply execute server-to-server non-ajax HTTP request (think of curl and WinHttp.WinHttpRequest) and pass status and data back to the caller. It works, but obviously not very efficient because it has to perform two HTTP requests.

In my case, solution is a combination of all the things described above plus 'Access-Control-Allow-Origin' header.

<pre><code>$.support.cors = true; // this must precede $.ajax({}) configuration

$.ajax({
 crossDomain: true, // added in jQuery 1.5
 headers: {
 'Access-Control-Allow-Origin': '*'
 },
 ...
});
</code></pre>

The web service that answers these calls also responds with 'Access-Control-Allow-Origin: *' header.

Try this solution: 

<a href="https://stackoverflow.com/a/14463975/237091">https://stackoverflow.com/a/14463975/237091</a>

Or, simply put this code in your HTML right after including jquery.

<pre><code>&lt;!--[if lte IE 9]&gt;
&lt;script type='text/javascript' src='//cdnjs.cloudflare.com/ajax/libs/jquery-ajaxtransport-xdomainrequest/1.0.3/jquery.xdomainrequest.min.js'&gt;&lt;/script&gt;

I just changed the jquery version and replaced the CDN link and it worked! Just do it if <code>crossDomain:true</code> and <code>$.support.cors</code> = true not work.

I need to use foursquare API to search venues. Of course it is cross-domain. 

It has no any problems in Firefox but in Internet Explorer (7, 8, 9 I've tested).

My javascript code looks like:

<pre><code>searchVenues: function(searchQuery) {
 $.ajax({
 url: 'https://api.foursquare.com/v2/venues/search',
 data: {
 sw: bound_south_west,
 ne: bound_north_east,
 query: searchQuery.query,
 oauth_token: FSQ_OAUTH_TOKEN,
 limit: 25,
 intent: 'browse',
 v: 20120206
 },
 cache: false,
 dataType: 'json',
 success: function(data) {
 displayResults(data, searchQuery.query);
 },
 error: function(xhr, status, errorThrown) {
 console.log(errorThrown+'\n'+status+'\n'+xhr.statusText);
 }
 });
}
</code></pre>

In Firefox, it perfectly displays received data.
In Internet Explorer, it logs on console:

<pre><code>No Transport
Error
Error
</code></pre>

What should I do?

'No Transport' Error w/ jQuery ajax call in IE

我需要使用foursquare API来搜索场馆。当然，它是跨域的。它在Firefox中没有任何问题，但在Internet Explorer中(我已经测试过7，8，9)。我的javascript代码看起来像这样：searchVenues: function(searchQuery) {    $.ajax({     ...
