Here is a very simple program and the output should be JavaScript but I am only getting s.
<html>
<head>
<title></title>
<script type="text/javascript">
document.getElementById("ma").innerHTML="JavaScript";
</script>
</head>
<body>
<h1 id="ma">s</h1>
</body>
</html>
The element doesn’t exist at the time you’re attempting to set a value. You need to call this after the
<h1>has been added to the DOM.You can either move this
<script>tag down further, or add your logic to a function which ought to be called when the document has been loaded:Demo: http://jsfiddle.net/Lr2Hm/
