笔记：实现类似微信朋友圈图片预览功能-五八三

效果

先看效果图，再讲解，遇到这个需求，感觉还挺有意思的，记录下来

思路

我的思路是这样，有六张或者九张图片，肯定是有很多个朋友发朋友圈的，每一个朋友是一个数组，而他发多少张图片又是一个数组，所以是可以循环的。这里我把朋友数组命名为 arr1，图片数组命名为arr2

这样的话，我在预览的时候，我就点击其中一个朋友的的图片进行预览，就个给图片加上点击事件，传两个参数，一个是this，一个是索引，这样我就可以准确的知道，我点击的是哪个朋友的图片，以及是哪张图片。

当我知道这两个东西后，就很容易去实现上面的效果了，刚开始的时候，我是想着把整个arr2做为参数传递过去的，但是后端返回的数据，这个arr2数组里面不止有图片路径还有很多其他的参数，所以我在传的时候一直在报语法错误，

后面想到一个办法，就是在这个图片单独的父容器储存起来，用的时候再取就好了，这样我就可以在点击的时候，获取到arr2里面所有的图片路径了，

然后再应用swiper轮播图插件，把获取的图片用一个轮播图存起来，进行循环，这个就实现了，上面的效果，

第一步

点击图片获取对应列表下面的所有图片，我的实现方案是这样的：
我把对应的src放到img图片容器的父级div上面，用data-img存下来


<div class="template-list" data-img="./image/pro1.webp">
    <div class='imagebox'>
        <img src="./image/pro1.webp" onclick="imgShow(this,0)" class="template-img"
            alt="FREE SHIPPING" width="70" height="70">
    </div>
</div>
<div class="template-list" data-img="./image/pro1.webp">
    <div class='imagebox'>
        <img src="./image/pro1.webp" onclick="imgShow(this,0)" class="template-img"
            alt="FREE SHIPPING" width="70" height="70">
    </div>
</div>
<div class="template-list" data-img="./image/pro1.webp">
    <div class='imagebox'>
        <img src="./image/pro1.webp" onclick="imgShow(this,0)" class="template-img"
            alt="FREE SHIPPING" width="70" height="70">
    </div>
</div>

然后循环，这样就可以获取到整个容器下面的src了

下面是获取data-img的js


var templatelist = ""
templatelist = $(that).parents(".sum-give").find(".template-list");
var imagroe = [];
for (let i = 0; i < templatelist.length; i++) {
    imagroe.push(templatelist.eq(i).attr("data-img"))
}
var templatelist = ""

templatelist = $(that).parents(".sum-give").find(".template-list");

var imagroe = [];

for (let i = 0; i < templatelist.length; i++) {

    imagroe.push(templatelist.eq(i).attr("data-img"))

}
var templatelist = ""

templatelist = $(that).parents(".sum-give").find(".template-list");

var imagroe = [];

for (let i = 0; i < templatelist.length; i++) {

    imagroe.push(templatelist.eq(i).attr("data-img"))

}

第二步

就是你点击的时候，需要创建一个容器来储存这个图片轮播图。

设置点击事件也就是onclick="imgShow(this,0)"，带入索引的目的，后面再说，这个索引很关键。

点击的时候，在body里面创建一个容器，代码如下：


var templatelist = ""
templatelist = $(that).parents(".sum-give").find(".template-list");
var imagroe = [];
for (let i = 0; i < templatelist.length; i++) {
    imagroe.push(templatelist.eq(i).attr("data-img"))
}
var html = ""
html += "<div id='back-curtain' onclick='backcurtain()' style='position:fixed;top:0;left:0;background:rgba(0,0,0,1);z-index:998;width:100%;display:none;'>";
html += "<div id='imgDiv' style='position:absolute;'>";
html += "<div class='swiper curtain-mySwiper'>";
html += "<div class='swiper-wrapper'>";
for (let i = 0; i < imagroe.length; i++) {
    html += "<div class='swiper-slide'>";
    html += "<img class='bigImg' src='' />";
    html += "</div>";
}
html += "</div>";
html += "<div class='swiper-pagination'></div>";
html += "</div>";
html += "</div>";
html += "</div>";
$("body").append(html)
var templatelist = ""

templatelist = $(that).parents(".sum-give").find(".template-list");

var imagroe = [];

for (let i = 0; i < templatelist.length; i++) {

    imagroe.push(templatelist.eq(i).attr("data-img"))

}

var html = ""
html += "<div id='back-curtain' onclick='backcurtain()' style='position:fixed;top:0;left:0;background:rgba(0,0,0,1);z-index:998;width:100%;display:none;'>";
html += "<div id='imgDiv' style='position:absolute;'>";
html += "<div class='swiper curtain-mySwiper'>";
html += "<div class='swiper-wrapper'>";
for (let i = 0; i < imagroe.length; i++) {
    html += "<div class='swiper-slide'>";
    html += "<img class='bigImg' src='' />";
    html += "</div>";
}
html += "</div>";
html += "<div class='swiper-pagination'></div>";
html += "</div>";
html += "</div>";
html += "</div>";
$("body").append(html)
var templatelist = ""

templatelist = $(that).parents(".sum-give").find(".template-list");

var imagroe = [];

for (let i = 0; i < templatelist.length; i++) {

    imagroe.push(templatelist.eq(i).attr("data-img"))

}

var html = ""
html += "<div id='back-curtain' onclick='backcurtain()' style='position:fixed;top:0;left:0;background:rgba(0,0,0,1);z-index:998;width:100%;display:none;'>";
html += "<div id='imgDiv' style='position:absolute;'>";
html += "<div class='swiper curtain-mySwiper'>";
html += "<div class='swiper-wrapper'>";
for (let i = 0; i < imagroe.length; i++) {
    html += "<div class='swiper-slide'>";
    html += "<img class='bigImg' src='' />";
    html += "</div>";
}
html += "</div>";
html += "<div class='swiper-pagination'></div>";
html += "</div>";
html += "</div>";
html += "</div>";
$("body").append(html)

这里需要注意一下，要引入两个js一个jquery.js,一个swiper.js,还有一个swiper.css,这些对应的官网都是可以下载的。
把这个空的容器添加好以后，就要放图片进去了，用jq的attr方法，代码如下：


 for (let i = 0; i < imagroe.length; i++) {
    $(".bigImg").eq(i).attr("src", imagroe[i]);
}
 for (let i = 0; i < imagroe.length; i++) {
    $(".bigImg").eq(i).attr("src", imagroe[i]);
}
 for (let i = 0; i < imagroe.length; i++) {
    $(".bigImg").eq(i).attr("src", imagroe[i]);
}

到这里基本上就已经实现了，上面的效果

重点，之前说的那个索引，我在看朋友圈的时候，有发现，你预览图片的时候，你点击的是哪一张，就会预览哪一张，然后下面的小圆点也会是在那一张的那个索引下面，所以索引的作用来了，刚好又发现swiper有一个属性initialSlide，刚好是记录索引的，然后完美解决了这个问题，代码如下：


 var swiper = new Swiper(".curtain-mySwiper", {
    pagination: {
        el: ".swiper-pagination",
    },
    initialSlide: newindex
});
 var swiper = new Swiper(".curtain-mySwiper", {
    pagination: {
        el: ".swiper-pagination",
    },
    initialSlide: newindex
});
 var swiper = new Swiper(".curtain-mySwiper", {
    pagination: {
        el: ".swiper-pagination",
    },
    initialSlide: newindex
});

第三步

不知道你们有没有发现，就是你发微信朋友圈的时候，不管你发的横图还是竖图，最后面展示出来的都是一样的大小，而不是这样，图片大小不一，这样很不好看

比如说这个：
我这里用的是放大，裁剪，给容器设置一个高度，然后超出隐藏，然后再用js来获取图片的高度来判断，图片具体是放大多少，
这里做了一下测试，就是一种很极端的情况下，也是可以的。如下图：

然后是放大，裁剪后的效果：

怎么样，是不是好看的很多

下面是完善的代码，

比如说，设置预览图片的样式，


$(".bigImg").css({ 'width': '100%', 'height': 'auto' });
            // 图片位置
$("#imgDiv").css({ 'top': '50%', 'left': '50%', 'transform': 'translate(-50%,-50%)', 'width': '96%' });
// 图片淡入
$("#back-curtain").fadeIn("fast");
// 遮罩效果
$("#back-curtain").css({
    'position': 'fixed',
    'overflow-y': 'auto',
    'width': '100%',
    'height': '100%',
    'z-index': '998'
}).show();
$(".bigImg").css({ 'width': '100%', 'height': 'auto' });
            // 图片位置
$("#imgDiv").css({ 'top': '50%', 'left': '50%', 'transform': 'translate(-50%,-50%)', 'width': '96%' });
// 图片淡入
$("#back-curtain").fadeIn("fast");
// 遮罩效果
$("#back-curtain").css({
    'position': 'fixed',
    'overflow-y': 'auto',
    'width': '100%',
    'height': '100%',
    'z-index': '998'
}).show();

$(".bigImg").css({ 'width': '100%', 'height': 'auto' });
            // 图片位置
$("#imgDiv").css({ 'top': '50%', 'left': '50%', 'transform': 'translate(-50%,-50%)', 'width': '96%' });
// 图片淡入
$("#back-curtain").fadeIn("fast");
// 遮罩效果
$("#back-curtain").css({
    'position': 'fixed',
    'overflow-y': 'auto',
    'width': '100%',
    'height': '100%',
    'z-index': '998'
}).show();

以及点击关闭这个模态框


//模态框点击事件
function backcurtain() {
    $("#back-curtain").remove()
}
//模态框点击事件
function backcurtain() {
    $("#back-curtain").remove()
}
//模态框点击事件
function backcurtain() {
    $("#back-curtain").remove()
}
