How can I find the index of an object inside a Array using underscore.js?

Question

I want to get the index of the given value inside a Array using underscore.js.

Here is my case

var array = [{\'id\': 1, \'name\': \'xxx\'},

In case you have complicated objects, and want to search one object in the collection looking for a certain property, just go with:

 _.indexOf(arrayObj, _.findWhere(arrayObj, {id: 1})  );

Where "arrayObj" is the collection with objects, "id" is the prop, and "1" is the value being in search.
