jQuery filter :contains for a link (a href="#")

I have a link that is currently:

a href="#" 

but soon the client will change the link to

a href="something"

When the link becomes somethi开发者_Python百科ng I would like to use jQuery to change the css, but I am not sure how to write a filter for an attribute (href="")...

Here are two options that you can use to compare your href attribute:

Href is empty:

$('a[href=""]') or $('a[href="#"]')

Href isn't empty:

$('a[href!=""]') or $('a[href!="#"]')

When comparing attributes, jQuery offers several operators for comparisions:

 = Is Equal
!= Is Not Equal
^= Starts With
$= Ends With
*= Contains

Here's a selector for an anchor with an href not equal to hash:

$('a[href!="#"]')

A quick read on jQuery selectors should do the trick (as mentioned by Rionmonster above). I'd just like to note that you can also check for elements with a specific attribute (which I expect you'll actually need?) by doing something like

$('a[href]')

This finds <a> elements that have a defined href attribute, whether that be a hash or anything else. Good for filtering out clickable anchors.
