user ajax to get data without "onClick function" in javaScript -


i've been searching example of getting data using ajax without onclick function of example found within onclick funtion.
here html data using onclick funtion

<!doctype html> <html lang="en"> <head>    <meta charset="utf-8" />    <title>new document</title>     <script type = 'text/javascript' src='js/jquery-2.2.0.js'></script>  <script type ='text/javascript' src='js/testscript.js'></script>  <?php include_once("database_conn_getoffers.php"); ?> </head> <body>    content goes here    <aside id="offer" onclick ="loaddoc('getdata.php',myfunction)">         &nbsp; click here         </aside> </body>

here script

function loaddoc(url, cfunction) {   var xhttp;   xhttp=new xmlhttprequest();   xhttp.onreadystatechange = function() {     if (this.readystate == 4 && this.status == 200) {       cfunction(this);     }   };   xhttp.open("get", url, true);   xhttp.send(); } function myfunction(xhttp) {   document.getelementbyid("offer").innerhtml =   xhttp.responsetext; }
