Events in Firefox

[irida]

Hello all!
I have a problem. When I'm writing a script to validate maxlength in the textarea element, I use event.returnValue=false (or just return false).
But it works only in IE. How should I change it to work in Mozila\firefox or any other browser.
Thanks a lot!

"Event" is an IE-only property. To be cross-browser, you need to pick up on the event data passed implicitly into your event handler.

Can you show the code you've got (HTML & JS)? It'd be easier to retrofit that way.

thanks!

function guardMaxLength(ta)
{
//check length after each time the key is pressed
maxlength=parseInt(ta.maxlength,10);
if(ta.value.length>=maxlength)
{

event.returnValue=false;
}
ta.value=value;
}
function ensureMaxLength(ta)
{
//check length before pasting
if(window.event.propertyName=='value')
{
ta=window.event.srcElement;
if(ta.value.length>ta.maxlength) {
ta.value=ta.value.substr(0,ta.maxlength);
}

}
}

<textarea maxlength="10" onkeypress="return guardMaxLength(this)" onpropertychange="return ensureMaxLength(this)">
