Ajax object

I think the ajax object in it must have attracted a lot of people. A large number of encapsulated ajax logic classes are of great help to us beginners using ajax.
The following is an example of my use: See here
1.
You can create it like this

Copy the codeThe code is as follows:

var url = 'http://yoursever/your/your'; 
var pars = 'id=xxx'; 
var myAjax = new ( 
                    url, 
                    {method: 'get', parameters: pars, onComplete: yourfunction} 
                    ); 

parameters represent the parameters you want to pass, such as id=xxx.
The stages of XMLHttpRequest during HTTP request are divided into: Loading, Loaded, Interactive, Complete.
Objects can call your customized methods at any stage, such as onxxxxxx:yourfunction, such as onComplete mentioned above, which is the most commonly used.
The actual code used in the example

Copy the codeThe code is as follows:

function sends(id) 
{ 
    c = $('content'); 
    o = $('old-content'); 
= "<div id='loading'>Loading...</div>";
     = ; 
     = 'none'; 
     = 'block'; 
    var myAjax = new ('content_'+ id + '.html', {method: 'get', onComplete:updates}); 
} 
function updates(response) 
{ 
    new ($('old-content')); 
    new ($('content')); 
    $('content').innerHTML = ; 
}
