Javascript validation for apostrophe

I'm looking for Javascript validation that will stop a ' (apostrophe) being entered into a HTML textbox form field.

Anyone have this?

Thanks

check out the onKeyPress event, using that you can check the character that was pressed and then if it is ' ignore it. Check out http://developer.irt.org/script/1214.htm for an example.

<input onkeyup="if (/'/.test(this.value)){this.value=this.value.replace(/'/g,'')}" onblur="this.onkeyup()">
