Sorry i dont have any idea about it.

[ExpertsGuide]

Try checking for the presence of non-digit chars and then falsify it.

var isNonDigitPresent= /\D/g; 
if(isNonDigitPresent)
  alert('non digit present');
else
  alert('it is a number');

Try this...

{
var x=document.forms["myForm"]["fname"].value;
if (x==null || x=="")
{
alert("First name must be filled out");
return false;

You can check for numerical keystrokes:

jQuery(document).ready(function() {
	$("#id").keydown(function(event) {
var digits = [48,49,50,51,52,53,54,55,56,57,96,97,98,99,100,101,102,103,104,105];
var legalKeyCode = (!event.shiftKey) && (jQuery.inArray(event.keyCode, digits) >= 0);
if (legalKeyCode === false) {return false;**
	**);
**);

Or you can try regex:

// Expression: /^[0-9]+$/
// Replace function:
.replace(/^[0-9]+$/,"")

Honestly, I didn't expect you to respond. I thought you were a bot or something, thus I apologize for calling you retarded. We all make mistakes. Anyways the thread author never thanked us anyways so ehh.
