Question

I want to call AJAX on subdomain using jquery ajax() method:
I call it from http://domain.com/

$.ajax({
    crossDomain: true,
    url:'https://sub.domain.com/',
    success: function(response) {
        alert('ok');
    },
    error: function(resp) {
        console.log(resp);
    }
});

But it doesn’t work, calls error function with resp == {
status:0, readyState: 0, responseText : '', statusText: 'error'
}

Answer 1

Sub-domain ajax calls are also cross domain. This is even true if they point to the same place (like example.com and http://www.example.com). They (usually) point to the same place. We see them as the same thing. But to an Ajax call, it’s considered cross domain.

Please do a search on crossdomain ajax and you’ll find a lott to go on.
