Question

Suppose I have two p tags in the document. I want to call two different effects using jQuery when onMouseOver event happens. Is it necessary that these two p tags be given Ids. Can’t it be achieved without giving Ids to these tags ?

Answer 1

You don’t have to give anything an id, however it is the best way to uniquely identify an element.

You can instead idenfity by class:

$(".myClass")

By attribute:

$("[src='image.jpg']")

By position in parent:

$("p:eq(2)")

A full list of selectors is available in the documentation
