Using ajax or what ?

You would want to do an AJAX request, somewhere along the lines of

var xmlhttp = new XMLHttpRequest();
xmlhttp.open("GET", "http://YOURSERVER/mypage.aspx", false);
xmlhttp.send();

//do something with the result
alert(xmlhttp.responseXML.text);

See the XMLHttpRequest Object for more details
