How to validate all fields with a certain name

I use the below IF statement to validate a single text field input box called "PhoneNum" on submit. It allows either blank, or 10 digits. I need to apply this logic to all fields with the word "PhoneNum" in the text box name. The fields are added dynamically, so I need to look for all input boxes with "Phonenum" in the name.

I'd like to keep it in an if statement, and use jQuery to do this, with something like: $("[name*=PhoneNum]").....

Could someone assist?
var PhoneNum = $("#PhoneNum").val();

	    if(/^(\d{0}|\d{10})$/.test(PhoneNum) == false) {
	    	alert("All Phone Number fields can only contain 10 digits.");
	    	$( "#PhoneNum" ).focus();
	        return false;
	    	}

try this:

$([name*="PhoneNum"]).each(function(){
var PhoneNum = $( this .val();

	    if(/^(\d{0}|\d{10})$/.test(PhoneNum) == false) {
	    	alert("All Phone Number fields can only contain 10 digits.");
	    	$(  this  ).focus();
	        return false;
	    	}
});

This doesn't seem to work. Below is what my function looks like.

<script type="text/javascript">
	window.onload = function() {
    document.getElementById("Submit").onclick = function() {
$([name*="PhoneNum"]).each(function(){
var PhoneNum = $( this .val();

	    if(/^(\d{0}|\d{10})$/.test(PhoneNum) == false) {
	    	alert("All Phone Number fields can only contain 10 digits.");
	    	$(  this  ).focus();
	        return false;
	    	}
});
</script>

looks like a missing ) on line 5, it should be:

var PhoneNum = $( this ).val() ;

Thanks but that still didn't fix it.

I ended up having to create a new function outside of the submit, and then returning the function in the submit.
