我正在使用此灯箱插件:http://s.codepen.io/schadeck/pen/gjbqr
我想知道是否有任何方法可以在我当前的代码中添加简单的描述属性。
我想要实现的是灯箱图像底部的描述文字。我找了一个解决方案,但似乎没有什么似乎适用于我正在使用的lightbox.js脚本。
以下是代码:
jQuery(document).ready(function($) {
// global variables for script
var current, size;
$('.lightboxTrigger').click(function(e) {
// prevent default click event
e.preventDefault();
// grab href from clicked element
var image_href = $(this).attr("href");
// determine the index of clicked trigger
var slideNum = $('.lightboxTrigger').index(this);
// find out if #lightbox exists
if ($('#lightbox').length > 0) {
// #lightbox exists
$('#lightbox').fadeIn(300);
// #lightbox does not exist - create and insert (runs 1st time only)
} else {
// create HTML markup for lightbox window
var lightbox =
'<div id="lightbox">' +
'<p>Clique para fechar</p>' +
'<div id="slideshow">' +
'<ul></ul>' +
'<div class="nav">' +
'<a href="#prev" class="prev slide-nav">Anterior</a>' +
'<a href="#next" class="next slide-nav">Proxima</a>' +
'</div>' +
'</div>' +
'</div>';
//insert lightbox HTML into page
$('body').append(lightbox);
// fill lightbox with .lightboxTrigger hrefs in #imageSet
$('#imageSet').find('.lightboxTrigger').each(function() {
var $href = $(this).attr('href');
$('#slideshow ul').append(
'<li>' +
'<img src="' + $href + '">' +
'</li>'
);
});
}
// setting size based on number of objects in slideshow
size = $('#slideshow ul > li').length;
// hide all slide, then show the selected slide
$('#slideshow ul > li').hide();
$('#slideshow ul > li:eq(' + slideNum + ')').show();
// set current to selected slide
current = slideNum;
});
//Click anywhere on the page to get rid of lightbox window
$('body').on('click', '#lightbox', function() { // using .on() instead of .live(). more modern, and fixes event bubbling issues
$('#lightbox').fadeOut(300);
});
// show/hide navigation when hovering over #slideshow
$('body').on(
{ mouseenter: function() {
$('.nav').fadeIn(300);
}, mouseleave: function() {
$('.nav').fadeOut(300);
}
},'#slideshow');
// navigation prev/next
$('body').on('click', '.slide-nav', function(e) {
// prevent default click event, and prevent event bubbling to prevent lightbox from closing
e.preventDefault();
e.stopPropagation();
var $this = $(this);
var dest;
// looking for .prev
if ($this.hasClass('prev')) {
dest = current - 1;
if (dest < 0) {
dest = size - 1;
}
} else {
// in absence of .prev, assume .next
dest = current + 1;
if (dest > size - 1) {
dest = 0;
}
}
// fadeOut curent slide, FadeIn next/prev slide
$('#slideshow ul > li:eq(' + current + ')').fadeOut(750);
$('#slideshow ul > li:eq(' + dest + ')').fadeIn(750);
// update current slide
current = dest;
});
});
HTML:
<ul id="imageSet">
<li><a href="" class="lightboxTrigger"><img src="" title=""></a></li>
</ul>

我没看过剧本,但你可以试试这个:
var desc = ['some description title', 'another description title', 'etc'];
$('body').append(lightbox);
// fill lightbox with .lightboxTrigger hrefs in #imageSet
$('#imageSet').find('.lightboxTrigger').each(function(index) {
var $href = $(this).attr('href');
$('#slideshow ul').append(
'<li>' +
'<img src="' + $href + '">' +
'<span>' + desc[index] + '</span>' +
'</li>'
);
});
