javascript - How to check if jQuery object exist in array?

itemprop="text">

Given an item
and an array, I would like to know if
item exist in
array.

item
is a jQuery object, e.g. $(".c"). You can assume that
item.length ==
1.

array
is an array of jQuery objects, e.g. [$(".a"), $(".b")]. Each
item in this array may represent 0, 1, or more
objects.

Here is how I thought to implement
this: (live demo
here)

function
            inArray(item, arr) {
 for (var i = 0; i < arr.length; i++) {
 var
            items = $.makeArray(arr[i]);


 for (var k = 0; k <
            items.length; k++) {
 if (items[k] == item[0]) {
 return
            true;
 }
 }
 }

 return
            false;
}

Can
you find a more elegant implementation?
