以前写过一篇实现WordPress图片灯箱功能的文章，详见：lightgallery给你的WordPress网站快速实现图片灯箱效果。最近更新主题后发现该方式使用的js插件与主题使用的js插件存在冲突，作为半吊子的我自然是无法解决这个问题的，于是换个思路，去DUX中拿了一段代码来用，DUX是用swiper幻灯片轮播插件实现的，效果不错还能放大图片，完全和DUX主题一样，大家可以对比下本站与DUX的图片灯箱效果。

教程十分详细，但需要对自己的主题结构有了解，不要问我代码该加在哪里了！感兴趣的可以跟随本文一起实现这个功能。

使用Swiper实现图片灯箱功能

首先下载Swiper，建议去官方下载，注意，下载的压缩包里面包含Swiper的全部基础演示和未压缩的js、css文件，我们仅仅需要swiper文件夹下的swiper-bundle.min.js文件即可。

官方下载地址：https://www.swiper.com.cn/download/index.html

下载好后，我们需要在你主题中引入它，由于每个主题的构成方式不同，最简单的方式就是在WordPress中使用钩子添加一个底部JS。详见：新版WordPress需使用wp_enqueue_script管理js与css。也可以直接修改主题的footer.php文件，在HTML的</body>标签前添加如下代码即可。

<script type="text/javascript" src="你的swiper-bundle.min.js文件路径"></script>

然后需要在你的主题样式文件中添加如下样式代码，下面代码不保证在别的主题中不存在样式冲突。

以上完成后整个引入过程完成，接下来通过如下代码使用它，你可以编辑你的主题js文件，也可以直接在footer.php文件中添加。

<script>
$(function(){
var t = $(".article-content img").map(function(t, e) {
var i = $(this).parent()
, a = i.attr("href");
return "A" == i[0].tagName && a && /.(jpg|jpeg|webp|svg|bmp|png|gif)$/.test(a.toLowerCase()) ? a : $(this).attr("src")
})
, e = null;
$(".article-content img").each(function(i, a) {
var r = $(this).parent()
, n = r.attr("href")
, o = "A" == r[0].tagName && n && /.(jpg|jpeg|webp|svg|bmp|png|gif)$/.test(n.toLowerCase());
o && r.on("click", function() {
return !1
}),
$(this).on("click", function() {
if ("A" !== r[0].tagName || "A" == r[0].tagName && !n || o) {
clearTimeout(e);
for (var a = "", s = 0; s < t.length; s++)
a += '<div class="swiper-slide"><div class="swiper-zoom-container"><img src="' + t[s] + '"></div></div>';
var l = '<div class="swiper-container article-swiper-container"> <div class="swiper-wrapper">' + a + '</div> <div class="swiper-pagination"></div> <div class="swiper-button-next swiper-button-white"><i class="fa fa-chevron-right"></i></div> tttt<div class="swiper-button-prev swiper-button-white"><i class="fa fa-chevron-left"></i></div> </div>';
$("body").addClass("swiper-fixed").append(l);
var u = new Swiper(".article-swiper-container",{
initialSlide: i,
zoom: {
maxRatio: 5
},
pagination: {
el: ".swiper-pagination",
type: "fraction"
},
navigation: {
nextEl: ".swiper-button-next",
prevEl: ".swiper-button-prev"
},
on: {
click: function(t) {

t.target.className.indexOf("fa-") > -1 || t.target.className.indexOf("swiper-button") > -1 || (e = setTimeout(function() {
TBUI.bd.removeClass("swiper-fixed"),
$(".article-swiper-container").remove(),
u.destroy(!0, !0)
}, 50))
},
slideNextTransitionStart: function(t) {
$(".article-swiper-container .swiper-slide-prev img").addClass("article-swiper-no-transition")
},
slidePrevTransitionStart: function(t) {
$(".article-swiper-container .swiper-slide-next img").addClass("article-swiper-no-transition")
},
slideChange: function(t) {
$(".article-swiper-container .article-swiper-no-transition").removeClass("article-swiper-no-transition")
}
}
});
return !1
}
})
})
})
</script>

注意：请将上面代码中的article-content更改为你的主题文章内容容器元素的样式名，也可使用id等方式，参考jQuery的选择器。最后别忘了引入jQuery支持，并且jQuery需要在Swiper之前引入。

到此使用swiper实现图片灯箱功能完成，最后提醒大家在修改代码前请先备份文件！
