jQuery Attribute Selectors

Using attribute selectors in jQuery means you can easily find HTML web page elements without manually finding the elements inside the HTML which can often be like finding a needle in a haystack.

With jQuery attribute selectors you can manipulate HTML elements and create JavaScript variables from them, assign events to them, animate them, edit them and much more!

The beauty of these special selectors is that a simple jQuery attribute selector line can find and select several HTML elements all at the same time! Magic.

Here is how you do it:

$("[href]") //select all elements with an href attribute.

$("[href='#']") //select all elements with an href value equal to "#".

$("[href!='#']") //select all elements with an href attribute NOT equal to "#".

$("[href$='.jpg']") //select all elements with an href that ends with ".jpg".
