I'm using jquery to post data to a server, the server received the data, but the chrome still shows the error :
XMLHttpRequest cannot load `myServer:63373/api/sendData`. Origin `myServer:63385` is not allowed by Access-Control-Allow-Origin.
Here is my js code:
$.ajax({
type: 'POST',
url: 'myServer:63373/api/SendData',
crossdomain: true,
async: true,
data: myData,
dataType: 'json',
success: function(){ alert('success'); }
});
The strange thing is that the 'success' shows up after the request, and the server did receive the data, but then the error message shows up in the console. Is there any way to avoid this message?

Thanks for all you answers above but I think I've found the way, before I solve this I was trying to use two ways, Setting Access-Control-Allow-Origin in ASP.Net MVC - simplest possible method with the 87 votes and 32 votes, I found the answers at two different places, and both applied them, but it didn't work. Early this week, I tried to delete the code in the web.config and just left the code in C#, it works! Can't believe these two solutions have confliction.
Anyway, hope this could help others.

if situation are
your script is hosted on another server
or subdomain
or try to hit url with another port
this is cross-domian request. jquery can not fulfill cross-domain request.
if this is your issue , then you should use jsonp for this "jsonp " allows cross domain request.
try to do this with using jsonp.
for jsonp every call has a callback means there will be a value in url and you have to send respnse with this call back in php
means try this:-
$.ajax({
type: 'POST',
url: 'myServer:63373/api/SendData',
crossdomain: true,
async: true,
data: myData,
dataType: 'jsonp',
success: function(){ alert('success'); }
});
and in php
wrap your response in $_GET['_callback']."(".$response.")"; and echo it
you will get response in json .

"not allowed by Access-Control-Allow-Origin" is the reason. Put simply, you can't normally do an XHR call to a different domain/port/protocol from those of the webpage your javascript was included into.
Modern browsers allow you work around this with permission from the server administrator.
You make your Ajax request with the XHR2 API (http://www.html5rocks.com/en/tutorials/cors/)
The on the server side, you need to emit the following headers to allow access from the domain that served the page that included your javascript:
Access-Control-Allow-Origin: http://your-page-domain.com
Access-Control-Allow-Credentials: true
