The innerHTML property of elements in IE, is not part of the W3C DOM. Nevertheless, in response to customers' requests, Mozilla- and Gecko-based browsers (such as Netscape 6) decided to support it in builds dated May 19, 2000 or later (Mozilla M16 and later, Netscape 6 PR2 and later). Let's look at the following code sample:

<DIV ID="counter">Number of clicks = 0</DIV>
<INPUT TYPE="button" VALUE="Increment Counter" onclick="updateMessage()">
var hits = 0;
function updateMessage() {
  hits += 1;
  document.getElementById("counter").innerHTML = "Number of clicks = " + hits;
// -->

which looks like this on the Web:

Number of clicks = 0
The function updateMessage() is called every time the user clicks the button. The number of hits is incremented by one, and the content of the DIV counter is updated by the innerHTML property, via a simple assignment. Notice the usage of getElementById() which is common to both Netscape 6 and Internet Explorer.
