jQuery / Colorbox - create a separate link to open the colorbox?

I'm trying to open a jQuery Colorbox from a link outside the rest of the colorbox images. So, all of the examples look like this:

<a href="image1.png" rel="group1"><img src="thumb1.png" /></a>
<a href="image2.png" rel="group1"><img src="thumb2.png" /></a>
<script>$("a[rel='group1']").colorbox();</script>

OK, that's fine, but I a开发者_如何学JAVAlso need to open that colorbox from a separate link:

<a href="?"> this link should also open the colorbox </a>

What do I have to put where to do that? All of the colorbox examples just show what's in the first code block, and I'm no jQuery expert.

Here's a similar thing that worked for my project.

HTML

//I "display:none" the images gallery to hide them...
<div style="display:none;">
 <a href="image1.jpg" rel="example1">Grouped Photo 1</a>
 <a href="image2.jpg" rel="example2">Grouped Photo 2</a>
 <a href="image3.jpg" rel="example3">Grouped Photo 3</a>
</div>

//...then when I click on this JPG image the group of images (above) appear in a colorbox
<img src="circle1.jpg" width="147" height="149" alt="circle" class="circle1" />

Here's the JQUERY

$(document).ready(function(){

     //when i "click" on the image with a class of "circle1" it opens the "example1" group
     $('.circle1').click(function() {
        $("a[rel='example1']").colorbox({open:true});
     });

});

Ah, figured it out! This works:

Change the first link to:

<a href="image1.png" rel="group1" id="something"><img src="thumb1.png" /></a>

Then, set up our extra link like this:

<a href="#" onclick="$('#something').colorbox({rel:\'post' . $post->ID . '\', open:true});">click here</a>

This example works, but without next and previous selections: http://jsfiddle.net/pd6JN/8/

Try this:

$(".link-to-click").click(function() {
   $("a.colorbox-link").colorbox({open:true, rel:'colorbox-class-group'});
});
