How to 'pop' or 'shift' from jQuery set

Question

In Javascript, arrays should have methods pop and shift.

However, JQuery objects seem to be missing these methods:

$('div').shift(); // Error, shift is undefined $('div').pop(); // Error, pop is undefined $('div').splice(); // Splice is OK actually 

I wonder why these functions are missing - after all, the jquery object is just an array.

What's the easiest way of performing pop and shift functions on jquery objects?

Answer 1

They're missing because a jQuery object isn't an Array.

(function( $ ) {     $.fn.pop = function() {         var top = this.get(-1);         this.splice(this.length-1,1);         return top;     };      $.fn.shift = function() {         var bottom = this.get(0);         this.splice(0,1);         return bottom;     }; })( jQuery ); 

EDIT: .slice() doesn't modify the original object. Fixed to use .splice() instead.
