simple Below the sample code which handles Cross Domain AJAX POST requests: post.php

CORS works fine in all the latest browsers, but IE8 and IE9 don’t support this.

In order to use XDomainRequest in IE, request must be:
a). Only GET or POST
When Posting, the data will always be sent with a Content-Type of text/plain
b). Only HTTP or HTTPS
Protocol must be the same scheme as the calling page
c). Always asynchronous

Step 1). Add the script in

Step 2). You need to set contentType value text/plain in $.ajax request.

 var contentType ="application/x-www-form-urlencoded; charset=utf-8";
 
if(window.XDomainRequest) //for IE8,IE9
    contentType = "text/plain";
 
$.ajax({
     url:"https://www.pakainfo.com/php/post.php",
     data:"name=king&age=28",
     type:"POST",
     dataType:"json",   
     contentType:contentType,    
     success:function(result)
     {
        alert("here Display all the Data from Server"+JSON.stringify(result));
     },
     error:function(jqXHR,textStatus,errorThrown)
     {
        alert("Error display :You can not any data send Cross Domain AJAX simple requests: "+errorThrown);
     }
    });

Below is the sample code, works in all the browsers.
