IndexOf() doesn't wok in jquery with Array

If you are using an array and want to use indexOf for them, Just run this code before making any calls in indexOf()
Below code will create a function call .IndexOf if it doesn’t exists.

if (!Array.prototype.indexOf) {                   
                    Array.prototype.indexOf = function (elt /*, from*/) {
var len = this.length >>> 0;
var from = Number(arguments[1]) || 0;
                        from = (from < 0)
                         ? Math.ceil(from)
                         : Math.floor(from);
if (from < 0)
           from += len;
 
for (; from < len; from++) {
if (from inthis&&
this[from] === elt)
return from;
                                        }
return -1;
                    };
                }
