Copy this code and paste it in your HTML

/* this will work in all browsers(no jQuery needed) */
if (!Array.indexOf) {
  Array.prototype.indexOf = function (obj, start) {
    for (var i = (start || 0); i < this.length; i++) {
      if (this[i] == obj) {
        return i;
      }
    }
    return -1;
  }
}
 
//call
var i = haystack_array.indexOf("needle")
 
 
 
 
/* or you can use jquery instead */
 
//call
var i = jQuery.inArray("needle", haystack_array)
