Answer 1

you should use cross browser JavaScript AJAX code, or better to use jQuery ajax see below sample code

    var url = "http://yourpage.com";
    var xmlhttp;

    if (window.XMLHttpRequest) {
        // code for IE7+, Firefox, Chrome, Opera, Safari
        xmlhttp = new XMLHttpRequest();
    } else {
        // code for IE6, IE5
        xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");
    }

    xmlhttp.onreadystatechange = callback;

    xmlhttp.open("GET", url, true);
    xmlhttp.send();

I suggest you use either jQuery or AngularJs for sending AJAX requests rather than creating new ActiveXObject objects.

Girish gave you answer using pure javascript. I will give you an example of jQuery usage. Please see code below:

$.get('http://yourpage.com', function(){ /*callback*/ })
