obscure jquery syntax in supersized slider

Question

I was going through the supersized.3.2.5.js file of the full screen image slider - supersized. I can't understand the syntax of the following lines. Though I am not pasting the complete code here yet i think that is not any prob for the syntax explanation. /* Variables ----------------------------*/ var el = '#supersized', base = this; // Access to jQuery and DOM versions of element base.$el = $(el); base.el = el; I need the explanation of the last 2 lines ...

Answer 1

They just save the jQuery object and the id string in different variables The jQuery one gets prefixed with $ base.$el = jQuery Object version of el (#supersized) base.el == just the id (the string)
