how to add new function?

jkarpago

Hi,
I need to add a new function programatically.

I tried this:

var oScript = document.createElement('script');
oScript.type = 'text/javascript';
oScript.id = 'addedscript';
textNode = document.createTextNode("alert('hi');");
oScript.appendChild(textNode);
document.getElementsByTagName('head')[0].appendChild(oScript);

It works in firefox but not in ie.
Can anyone give me a solution?
thanks so much;

I guess you selected too complicated way to resolve the problem.
Addition of new function is equivalently to addition of new variable.
Example:

<html>
<head>
<script type="text/javascript">

var foo = function (){ alert('hi');};

</script>
</head>
<body>
<input type="button" onclick="foo();" value="Say 'hi'">
</body>
</html>

Maybe it helps.

Set the script elements .text property.

Or a new property, where the latter has the advantage that it can be
`delete'd after use.

<script type="text/javascript">

var foo = function (){ alert('hi');};
this.foo = function ()
{
alert('hi');
};
</script>
</head>
<body>
<input type="button" onclick="foo();" value="Say 'hi'">
