Question

This is my code.

 function ajax() {
   var ajaxRequest;
   try {
     ajaxRequest = new XMLHttpRequest();
   }
   catch (e) {
     try {
       ajaxRequest = new ActiveXObject("Msxml2.XMLHTTP");
     }
     catch (e) {
       try {
         ajaxRequest = new ActiveXObject("Microsoft.XMLHTTP");
       }
       catch (e) {
         alert("Your browser broke!");
         return false;
       }
     }
   }

   return ajaxRequest;
 }

 var ajax = ajax();
 ajax.Message = function (method, l) {
   ajax.open(method, url, false);
   ajax.send();
   ajax.onreadystatechange = function () {
     if (ajax.readyState == 4 && ajax.status == 200) {}
   }
 }

Every time I want to send a request, I need to use this function, but when I look the code in Youtube, or Twitter, I see that they don’t work like this.

Is there a short way to send AJAX? I mean only using JavaScript, without using jQuery.

Answer 1

Other sites use more or less what you posted or jQuery which is more or less what you posted under the covers.

You want the above shorter?

function a(l,d,u){try{r = new XMLHttpRequest();}catch(e){try {r = new ActiveXObject('Msxml2.XMLHTTP');}catch(e){r = new ActiveXObject('Microsoft.XMLHTTP');}} if(r){r.onreadystatechange = function() {if (r.readyState == 4 && r.status == 200){document.getElementById(u).innerHTML = r.responseText;}} r.open('GET', l+'?'+d, true);r.send(d);}}
