JQuery $(this) selector function and limitations

Question

I need help understanding $(this). Is it possible to narrow the focus of \'this\' within the parentheses or does \"this\" preclude the use of any other attributes?

Answer 1

First, you must to understand what is this, it is depend on an context. When you call $ function it will return a jQuery object.

$(this).children("div")

It means from specific object, get all children, see the below link: http://jsfiddle.net/vietean/f2Yrg/
