Question

How should I define whats going on here from left to right. I’m perplexed with the [0].nameofsomething part. Stupid quesiton for bonus, can the [0] be any other integer too? It looks like the jquery selector is now namespaced..is that correct?

$("#someselector")[0].nameofsomething = new MyObject();

and could this also be written like this….

$("#someselector").nameofsomething = new MyObject();

and produce exactly the same results?

thanks for any insight!

Answer 1

The [0] selects the DOM object, so you are adding to the element.

$("#someselector")[0].nameofsomething  // this is same thing as document.getElementById("someselector").nameofsomething = {};

You are adding to the jQuery object

$("#someselector").nameofsomething

So they are not the same thing.
