JQuery lightbox works with multiple galleries / links
I am trying to do this code that I contributed to the library:
$.fn.boxify = function() {
var imageSliding = $('.box > .img');
$(this).click(function() {
$('.backdrop, .box').animate({
'opacity': '.50'
}, 300, 'linear');
$('.box').animate({
'opacity': '1.00'
}, 300, 'linear');
$('.backdrop, .box').css('display', 'block');
});
$('.close').click(function() {
close_box();
});
$('.backdrop').click(function() {
close_box();
});
function close_box() {
$('.backdrop, .box').animate({
'opacity': '0'
}, 300, 'linear', function() {
$('.backdrop, .box').css('display', 'none');
});
}
/* Slider */
var speed = 100;
$(".prev").click(function() {
var gallery = $(this).closest('.box').find("ul.gallery"),
now = gallery.children(":visible"),
last = gallery.children(":last"),
prev = now.prev();
prev = prev.index() == -1 ? last : prev;
now.fadeOut(speed, function() {
prev.fadeIn(speed);
});
});
$(".next").click(function() {
var gallery = $(this).closest('.box').find("ul.gallery"),
now = gallery.children(":visible"),
first = gallery.children(":first"),
next = now.next();
next = next.index() == -1 ? first : next;
now.fadeOut(speed, function() {
next.fadeIn(speed);
});
});
$(".gallery li").click(function() {
var first = $(this).parent().children(':first'),
next = $(this).next();
next = next.index() == -1 ? first : next;
$(this).fadeOut(speed, function() {
next.fadeIn(speed);
});
});
};
$( "a" ).boxify(); // Makes all the links green.

Do you see the class .box
? As a user, I want to endlessly add more boxes containing different images and titles!
When I added another one <a>
, which is the Lightbox link in the box, both windows are displayed at the same time. I know the same code is reused this way, but this is what I am trying to do:
Somehow keep the same code without adding more and more code. However, when I add more boxes, they are completely different from the others (different images)

You can change your .click function to use it:
$(this).click(function(event) {
var lightBoxes = $('a.lightbox'); //Retrieves all a.lightboxes of the page
for (var i = 0; i < lightBoxes.length; i++) {
if (lightBoxes[i] == event.target) { //Checks the clicked element position in the array
//Displays the common .backdrop div
$('.backdrop').animate({
'opacity': '.50'
}, 300, 'linear').css('display', 'block');
//Displays the 'i' .box div
$('.box').eq(i).animate({
'opacity': '1.00'
}, 300, 'linear').css('display', 'block');
break;
}
}
});
This code checks all "a" elements with class .lightbox and checks which one was clicked. Knowing that the index (i) of the "a" item was clicked, the "i" .box item is displayed.
Note that the .backdrop element must be unique in HTML and do not need to be repeated. In HTML, you just need to add a new href element and a new div.box for each a.
<a href="#" class="lightbox">Open Lightbox 2</a>
<div class="box">
<ul class="gallery" id="olympGallery">
<li><img src="http://urbanphenomena.net/imgs/trabzoni/trabzoni1.png" alt="" title="" /></li>
<li><img src="http://urbanphenomena.net/imgs/trabzoni/trabzoni2.png" alt="" title="" /></li>
<li><img src="http://urbanphenomena.net/imgs/trabzoni/trabzoni3.png" alt="" /></li>
</ul>
<div class="slideButtons">
<span class="next">Next</span>
<span class="prev">Previous</span>
</div>
<div class="caption">
<p>This thing is called 'Caption'. Let me tell you:</p>

Hope this is what you need!
