Enter Numeric Values In Textbox

This code restricts the user from accidentally typing characters into a, say, phone number field...

The javascript goes like:

function isNumber(e)
{
    var code, num, regex;
    
    code = e.keyCode;
    num = String.fromCharCode(code);
    regex = /\d/;
    return regex.test(num);
}


The html code goes like:
