Question

What is the following structure called:

$('', { })

I see it often, for instance here from appending options to select elements:

$("#items").append($('<option>', { value : "mouthForWar" , text : "Pantera" }));

In the more general sense, is there any place where the different jQuery structures, formats, and syntax is concised on a single page? If one does not know the name of the syntax he is looking for, then there is no way to google for it!

Thanks.

Answer 1

$('<option/>', { value : "hej", text : "Hopp" })

actually creates this:

<option value="hej">Hopp</option>

It’s a convenient shortform. The jQuery function (mostly called through its alias $) is very versatile. Look it up: http://api.jquery.com/jQuery/#jQuery2

It’s called jQuery( html, props )
