Which Key Event should we use for validating special characters?
Hi,
Currently I have a TEXTAREA as attached.
In the onkeyup event, it will check for special characters and stop them while entering themselves.It is working fine.
But when I tried to copy some text with special characters from a notepad and paste it in the TEXT AREA, the validation is not working. I guess it is because of the "onkeyup" event.
Could you please suggest me how to resolve this. This validation should work in both the cases ie when typing in the text area as well as when copy and paste.
Thank you for your help!

<TD><TEXTAREA rows="18" cols="32" id="ITextArea" name="ITextArea" onfocus="limitTextarea(this,9999,30)" onkeyup="valid(this)" style="{width:305px; font-family: courier, 'courier new', monospace;}"></TEXTAREA></TD>
function valid(field)
{
var re = /^[a-zA-Z0-9\n\r\f]*$/;
if (!re.test(field.value))
{
field.value = field.value.replace(/[^a-zA-Z0-9\n\r\f]/g,"");
}
}
