Simple JQuery question - how do you add value to the title attribute?

Question

Stupid question time - how do you update the title attribute of a control? Obviously this does not work:

$("#valPageIndex").attr('title') = pageIndex;

TIA

Answer 1

$("#valPageIndex").attr({'title': pageIndex});

Answer 2

$("#valPageIndex").attr('title', pageIndex);

Basically, $("#valPageIndex").attr('title') is just for getting its value, while $("#valPageIndex").attr('title', value) is for setting it.

Here's the official doc: http://docs.jquery.com/Attributes/attr.

Answer 3

$("#valPageIndex").attr('title', pageIndex);

A common jQuery convention is to have .foo() or .foo('selector') act as a getter and .foo(value) or .foo('selector', value) act as a setter.
