JQuery property Selector

JQuery uses XPath expressions to select elements with a given attribute.

$("[href]") selects all elements with the href attribute.

$("[href=" # "]") selects all elements with a href value equal to "#".

$("[hrefraction =" # "]") selects all elements with a href value not equal to "#".

$("[href$=" .jpg "]") selects all elements whose href values end with ".jpg".
