Check if a string contains a specific number in JavaScript

Question

Possible Duplicate:
JavaScript: string contains

I want to check if a string contains a specific number in JavaScript, how can I rewrite the statement s contain d in below code?

var s = '11/14/2012';
var d = '14';
if (s contain d) {
    //...
}

My case is similar to Check if a string contains a certain number, but how can I implement this action in JavaScript?

Thanks

Might want to check using slashes to bound your value so you don't get false matches on the month or year if you're looking for the day as Syuaa mentioned in the answer below. — marvin, Nov 14 '12 at 04:19
@Jack there's no need to coerce to boolean (with `!!` or otherwise) in an `if` condition. — Matt Ball, Nov 14 '12 at 04:30
@Jack: That would be the case for a `return !!~s.indexOf(d)` for example. — elclanrs, Nov 14 '12 at 04:32
@elclanrs I meant that you reversed the logic in your earlier comment. — Ja͢ck, Nov 14 '12 at 04:33

The easier way is to use index Of.

if(s.indexOf(d) > -1)

var s = '11/14/2012';
var d = '14';
if (s.match(d)) {
   alert('Found');
}
