Dynamic HTML (DHTML) is an enhancement to HTML version 4.0, and can be used to create enhanced visual effects on a WWW page. It works with Microsoft Internet Explorer 4.0 and Netscape Navigator 4.0, and later. The simplest way to reference an element in DHTML is to use the elements id tag. For example:

DHTML example

<html><head><title>ID referencing</title></head>
<script type = "text/javascript">
function go()
{
alert(mytext.innerText);
mytext.innerText = "Goodbye";

}

</script>
<body onload="go()">
<p id="mytext">Hello, how are you?</p>
</body>
</html>

Executed code

Hello, how are you?
