[Javascript] maxLength question

[decren at yahoo.com (DeWayne Crenshaw)]

Hello,
I am having a problem in establishing maxLength of a
textBox depending on which radioButton is checked. It
seems that IE only establishes maxLength when a page
loads and does not allow you to change it once the
page has loaded.
Although I've tried a lot of manipulations, my rough
code is as follows, 

function changeLength()
{
if (document.myForm.radioButton[1].checked) {maxLength
=5}
else {maxLength =6}
}

<INPUT TYPE=TEXT NAME="textBox" id="textBox"
onfocus="changeLength()">

I'm looking for something that will work cross-browser
and would appreciate any pointers.
