Accept only numbers in Textbox - jQuery

Question

I need to implement a functionality for a textbox to allow only numbers. I have written the following code, but using Ctrl + V we are able to paste text. How can we prevent this.

$('.numeric-textbox').live('keypress', function (e) {
    if ((e.keyCode < 48) || (e.keyCode > 57)) {
        return false;
    }
});

Can someone suggest some solution. :)

What version of jQuery are you using? live() is deprecated in 1.7, and removed entirely in 1.9 (replaced with on()). — David Thomas

@ASTEROID why are you using 1.6.2? any reason not to update and pull the latest /1/ version? — Roko C. Buljan

Try

$('.numeric-textbox').bind("cut copy paste",function(e) {
          e.preventDefault();
      });

This will prevent cut copy paste event on your textbox
