Having issues with CORS?

Ajax and JSONP

This is how i manage to solve my CORS

$.ajax({
    	type: 'GET',
        url: 'https://example.com/filename.php',
        data:{postname:postname, postname2:postname2},
        dataType: 'jsonp',
        crossDomain: true,
    	success:function(data){
      // 		console.log(data);
    	}
 })
 
 
 
 
 
 When you go into your filename.php 
 
 
 if(issest($_GET['callback'])){
    $postname = $_GET['postname'];
    $postname2 = $_GET['postname2'];
    
    // Then do what you want with the information collected.
 
 }
