Hi experts,

I have a html called TestPage.html

When I run my page i have a textbox like this:
on page run
On page load the submit button is disabled.

Right now in my code above , the button becomes enabled when a user starts typing in the textbox (on the keyup event).

My textbox is social security number format.

social security number format is 9 digits.

So if a user doesn't type all 9 digits in the textbox they see this message:
message if user doesn't type in all 9 digits.

Anyone know a way that I can enable the button, not on the keyup event like i have it now,
but only after a user finishes typing in all 9 digits?

so then, if a user types in 123-45-6789  
at the moment after the ninth digit is typed in then enable the button at that point

>> not on the keyup event like i have it now,
Its is OK to use onkeyup to do your desired filtering.  You just need to extract the current value, and see if it has all the needed digits.

           // ****** textbox on keyup event ******
            $("#TextBox1").on("keyup", function () {
                var val=$(this).val().replace(/\D/g,'');
				if( /^\d{9}$/.test(val))
                	// enable button on keyup
                	$('#Button1').prop('disabled', false);
					//in case the user backspaces, you need to disable button again
					$('#Button1').prop('disabled', true);
