Comparing two arrays in jquery

Question

Using this code...

var a = [\'volvo\',\'random data\'];
var b = [\'random data\'];
var unique = $.grep(a, function(element) {
    return $.inArray(element, b         


        

Answer 1

This should probably work:

  var positions = [];
  for(var i=0;i

So your final array would be something like:

  var positions = [[0,2],[1],[3]...] 
  //implies a[0] == b[0],b[2], a[1] == b[1] and so on.

Hope it helps
