Answer 1

I think this question is already asked.In there are also answers not using plugin.I take it from here How to allow only numeric (0-9) in HTML inputbox using jQuery?

    jQuery.fn.ForceNumericOnly =
function()
{
    return this.each(function()
    {
        $(this).keydown(function(e)
        {
            var key = e.charCode || e.keyCode || 0;
            // allow backspace, tab, delete, arrows, numbers and keypad numbers ONLY
            return (
                key == 8 || 
                key == 9 ||
                key == 46 ||
                (key >= 37 && key <= 40) ||
                (key >= 48 && key <= 57) ||
                (key >= 96 && key <= 105));
        });
    });
};

$("#yourTextBoxName").ForceNumericOnly();
