Setting javascript function for all <a> - lightbox

Question

I have a lightbox script that Im using:
<a class="lb-image-link" href="images/image-1.jpg" data-lightbox="lb-set">
<img class="lb-image" src="images/thumb-image-1.jpg" width="150" height="150"/></a>
But for my clients sake to use CMS software I need to make the data-lightbox="lb-set" function work for all <a> tag on the page or to make it work as a class somehow if possible.
The page is HTML, how can I make this work? Im guessing I need to create javascript for this. Any help is greatly appreciated, thank you

Answer 1

One way would be to learn some jquery, if you are not already familiar with it
http://jquery.com/
and then you can easily attach a function to all click events on every a tag on the page with something like:
$("a").click(function(event) {
//your lighbox code goes here ...
});
EDIT
With the lightbox2 script you are using it doesn't look like there is a way to assign it to a group of links on your page based on class or tag type, so the above function is not relevant. At a quick glance, if you stick with that script the only way to have it work on multiple links on the same page is to include a unique data-lightbox="" attribute in each link, eg.
image #1
image #2
image #3
There are other lightbox scripts that allow you to set the lightbox based on tag type or class, for instance http://fancyapps.com/fancybox/ allows you to do the following:
<a class="fancybox" rel="group" href="big_image_1.jpg">image #1</a>
<a class="fancybox" rel="group" href="big_image_2.jpg">image #2</a>
and then use the script
<script type="text/javascript">
$(document).ready(function() {
$(".fancybox").fancybox();
});
</script>
the above essentially attaches the fancybox lightbox to anything that has a class="fancybox"
Not sure if that helps - there may not be much difference for you having to add a unique data-lightbox="image-3" to each link as apposed to adding a standard class to them :-)
