How to allow only numeric (0-9) in HTML inputbox using jQuery?

Here is the function I use:
// Numeric only control handler
jQuery.fn.ForceNumericOnly =
function()
{
return this.each(function()
{
$(this).keydown(function(e)
{
var key = e.charCode || e.keyCode || 0;
// allow backspace, tab, delete, enter, arrows, numbers and keypad numbers ONLY
// home, end, period, and numpad decimal
return (
key == 8 ||
key == 9 ||
key == 13 ||
key == 46 ||
key == 110 ||
key == 190 ||
(key >= 35 && key <= 40) ||
(key >= 48 && key <= 57) ||
(key >= 96 && key <= 105));
});
});
};
You can then attach it to your control by doing:
$("#yourTextBoxName").ForceNumericOnly();
