<textarea> proprietary attribute

[veenuisthebest]

thanks for replying but i'm not sure how to make it work !

see this is my actual textarea:-

<!-- Text Area -->
<textarea MaxChars="1000" name="description" id="description" rows="6" cols="50" style="width:540px" onkeypress="if (this.value.length >= parseInt(this.attributes['MaxChars'].value)) return false;" onkeyup=" document.getElementById( this.id+'_charsCount' ).innerHTML = (parseInt(this.attributes['MaxChars'].value)-parseInt(this.value.length));"></textarea>
<!-- Text Area -->

As you can see all my JS is within onkeypress and onkeyup attribute of textarea. Now how do I use setattribute for MaxChars ?

Thank you
