您如何多次使用.js id =？

Question

I have this code in functions.js

$("a#example2").fancybox({
'overlayShow' : false,
'transitionIn' : 'elastic',
transitionOut' : 'elastic'

and it works but brings up my only errors while validating as HTML5. This is because I am using six

id="example2"

instances in my gallery and it flags for multiple use. When I dug up the templates for this, it had example1, example2 etc. and I just converted all to the one I like. This is for a gallery on my website at http://www.shaneofalltrades.com . Thanks!

Answer 1

id= is intended to be an identifier unique to the whole DOM. class= allows you to group elements by a common identifier.

HTML:

<div class="someClass">Content</div>

CSS:

.someClass
{
  background:transparent;
  color:#990000;
}

.someClass div { ... }

jQuery:

$('.someClass').html()
$('.someClass div').html()

Answer 2

You can't. You should be using class="example2" instead.

So your selector will look like: $("a.example2").fancybox({...})

Answer 3

Short answer, you don't. That's what classes are for.

<a class="fancy">....

$('.fancy').fancybox(.....
