textbox characters restriction 1

[ghorr]

i need a script that can set restrictions concerning the characters i can enter in a textbox ...
for example i want a NAME field that would not allow the user to enter some special characters (E.G. '%','^','&','*')
help me pls

 

[ghorr]

one more thing ... it should not allow this on keyPress ... not on 'Submit'

Here's a quick example:

<script>

function restrict( el ) {

	el.value = el.value.replace( /[^a-zA-Z-']+/i, '' );
}

</script>

<input type=&quot;text&quot; onkeyup=&quot;restrict( this );&quot; />

I've used

onkeyup

'cause that makes it a little simpler than your idea of

onkeypress

.
