Need Form to Validate Phone Number Only

[ndwest12]

This is what I have so far, it is a template I copied from my working E-mail validation. I'm assuming I have to make it so it's just an array of numbers but I really don't know Java too well.

Essentially I just want numbers only to be accepted into the phone field.

else if(fieldType == 'phone')
				{	
					if((required == 1 && fieldObj.value=='')  ||  (fieldObj.value!=''  && !validate_phone(fieldObj.value)))
					{				
						fieldObj.setAttribute("class","mainFormError");
						fieldObj.setAttribute("className","mainFormError");
						fieldObj.focus();
						return false;					
					}

				}



				function validate_phone(phoneStr)
			{		
				apos=phoneStr.indexOf("@");
				

				if (apos<1||dotpos-apos<2) 
				{
					return false;
				}
				else
				{
					return true;
				}
			}

I wrote a function to check every phone number variation I could find. Just within the North American Numbering Plan, there are over 40 possibilities, and then multiple sub-formats. PM me if you'd like a copy of it.
