Hey all,
Just had a need for this, wondering if it is a candidate for inclusion as it
is only a single line and I can't seem to spot any other way of acheiving
the same functionality in less code.
String.prototype.isNumeric = function() { return (this.match(/^\d+$/) !=
null); }
I used it in the context of:
Event.observe(el,'keypress',function (e) { if (!this.value.isNumeric())
Event.stop(); });
Admittedly, it doesn't cater for decimal points and other locales, but it's
a start?
The regex came from inside the selector code in prototype, so it's used once
at present formula.match(/^\d+$/)
