you need create new xmlhttprequest, oopen it, , send request. create callback function handle result. example below:

var xmlhttp = new xmlhttprequest(); function callwebservice(){     xmlhttp.open('get', 'http://yourwebserviceurlhere', true);     xmlhttp.onreadystatechange = callbackfunction;     xmlhttp.send(); }  function callbackfunction(){     if (xmlhttp.readystate != 4)      return;  var result = xmlhttp.responsetext; alert(result);   }
