JavaScript Arrays

Does anyone now if there is a function in java script that would tell me how many times a certain string appears in an array. IE

Array[1] = 1
Array[2] = 2
Array[3] = 1

So if I searched for 1 it would tell me it appeared twice.

A bit crude and not tested - but you'll get the idea...

Code:

function countOccurences(array,item)
 {var j=0;
  for (var i=0;i<array.length;i++)
   {j+=array[i]==item?1:0;}
  return j;
 }
