Yes, use .get(index). According to the documentation:
The
.get()method grants access to the DOM nodes underlying each jQuery object.
I tested Aaron's statements on all the browsers I have available on my box:
$('#MyObject').get(0);
vs
$('#MyObject')[0];
As far as I can tell, it is only a matter of personal preference.
Functionally, both these statements are equivalent for both existing and non-existing elements. I tested the following browsers: Chrome 27.0, FF 21.0, IE10, IE9, IE8, IE7, IE6.
In the speed tests that I ran, it was not always possible to tell which variation was faster; the outcome was not always consistent, even on the same browser. For the speed tests, I only tested existing elements. My test results are here.
