There is a javascript function indexOf
var myArray = [9, 3, 4, 7];
var index = myArray.indexOf(4);
// index is 2
index = myArray.indexOf(6);
// index is -1

It will work if you're searching for strings but I would strongly recommend you to use jQuery or some other framework because it will help you a lot when working in Javascript.
If you use jQuery, maybe this plugin will help:

You can resort to indexOf if you (the client you are serving) have javascript 1.6
https://developer.mozilla.org/en/JavaScript/Reference/Global_Objects/Array/indexOf
On the same page there is also an equivalent function if you don't have the function implemented natively into the engine.
For further references on array methods you can read
