我已经搜索了Lightbox_me的关闭按钮的脚本，但是我能找到的只是用于裸机灯箱的脚本。

This is the jsfiddle with the script for Lightbox_me.
我尝试将裸机灯箱的关键按钮合并到Lightbox_me中，但我根本不知道从哪里开始。我是否必须单独将一个关闭按钮格式化到每个灯箱div上并简单地绑定closeLightbox();？或者是否有更优雅的方式来处理仅涉及脚本？
答案 0 :(得分：1)
默认情况下，脚本具有以下定义：
$.fn.lightbox_me.defaults = {
// animation
appearEffect: "fadeIn",
appearEase: "",
overlaySpeed: 250,
lightboxSpeed: 300,
// close
closeSelector: ".close",
closeClick: true,
closeEsc: true,
// behavior
destroyOnClose: false,
showOverlay: true,
parentLightbox: false,
preventScroll: false,
// callbacks
onLoad: function () {},
onClose: function () {},
// style
classPrefix: 'lb',
zIndex: 999,
centered: true,
modalCSS: {
top: '100px'
},
overlayCSS: {
background: 'black',
opacity: .3
}
}
您会在关闭部分注意到它默认使用类＆＃34;关闭＆＃34;来查找元素。
因此，如果您在灯箱内贴上该类的div，请按照您的方式设置，然后触发关闭操作。
基于脚本关闭的逻辑：
if (opts.closeClick) {
$overlay.click(function (e) {
closeLightbox();
e.preventDefault;
});
}
$self.delegate(opts.closeSelector, "click", function (e) {
closeLightbox();
e.preventDefault();
});
逻辑的这一部分告知lightbox_me，如果closeClick在传递给它的选项列表中为真，那么它将设置覆盖图上的点击以关闭灯箱。
它还会将当前和未来元素与opts.closeSelector中定义的值绑定，以便在单击时启动closeLightbox函数。
