jQuery inArray is always returning -1

Question

I cannot figure out why I keep getting -1 for lastProductIndex when clearly the lastProductID is in the array!

var lastProductID = 6758;
var allProductIDs =          


        

Answer 1

Try this instead:

$.grep(allProductIDs, function(n) { return n == lastProductID; });

Caveat: grep returns an array.

It looks like jQuery does an === instead of == with inArray.
