Why is it that document.getElementById("xxxxx") does not seem to be functioning whatsoever?

Question

Why is it that document.getElementById("xxxxx") does not seem to be functioning whatsoever?

I'm struggling to assign the value of a String Variable to a specific element in the DOM within a particular div.

Let's use an example: game=TEN

document.getElementById("game").innerHTML=game;

The issue is that it does not write to:

<div id="game"></div>

The problem lies with the following code. I have a script where, at the end of it, I can document.write(game) and everything works fine, but I'm unable to write it to the div? Perhaps I am approaching this incorrectly.

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<title>Untitled Document</title>
</head>
<body>

...

</script>

<div id="game" style="font-family:Arial, Helvetica, sans-serif; font-size:12px; line-height:16px">hello</divЮ
</body>
</html>

Answer №1

When you run the script and search for the element, it may not exist yet because it is added later.

In other words, the element has not been parsed and inserted into the DOM at that point.

To ensure the script can find the element, consider moving your scripts to the bottom of the HTML file (at least after the element).

If you are using a library like jQuery, you can easily solve this issue by placing your code inside a $(function() { ... }) block. This way, the code will only execute after the DOM is fully loaded and you can safely locate the element.

At the moment when you try to access the #game element, it may not have been created yet. To ensure that your code runs after the element has been created, you should wait for the onload event and bind your function to this event:

<script type="text/javascript">
function initialize() {
   /**your code here**/
}
</script>

<body onload="initialize()">
<div id="game"></div>
</body></html>

The Init() function won't function properly as the DOM hasn't fully loaded. To resolve this issue, you can either utilize jQuery or Dojo and implement the document ready functions, or move the javascript block to the end of your html document, just before the closing body tag.

Consider using Firebug, and modify the code as shown below:

<html>
<body>
<div id="myid"></div>
</body>
<script language="Javascript">
document.getElementByID('myid').innerHTML = ....
</html>
