图片预览

mui自带有图片预览脚本，但在官网上没有明确给出相关实现代码

使用mui自带的图片预览功能首先要引入其本身的几个文件：

mui.min.css

mui.min.js mui.zoom.js mui.previewimage.js

初始化图片预览：

mui.previewImage();
1

图片标签要加上两个属性：data-preview-src="" data-preview-group="1"

<img src="../images/muwu.jpg" data-preview-src="" data-preview-group="1" />
1

上面做完发现图片预览还是不生效，在网上找到的方法是引入mui的mui.imageviewer.css文件，但实际发现引入并不起作用。

这里需要自己写一个css文件：

.mui-preview-image.mui-fullscreen {
    position: fixed;
    z-index: 20;
    background-color: #000;
}
.mui-preview-header,
.mui-preview-footer {
    position: absolute;
    width: 100%;
    left: 0;
    z-index: 10;
}
.mui-preview-header {
    height: 44px;
    top: 0;
}
.mui-preview-footer {
    height: 50px;
    bottom: 0px;
}
.mui-preview-header .mui-preview-indicator {
    display: block;
    line-height: 25px;
    color: #fff;
    text-align: center;
    margin: 15px auto 4;
    width: 70px;
    background-color: rgba(0, 0, 0, 0.4);
    border-radius: 12px;
    font-size: 16px;
}
.mui-preview-image {
    display: none;
    -webkit-animation-duration: 0.5s;
    animation-duration: 0.5s;
    -webkit-animation-fill-mode: both;
    animation-fill-mode: both;
}
.mui-preview-image.mui-preview-in {
    -webkit-animation-name: fadeIn;
    animation-name: fadeIn;
}
.mui-preview-image.mui-preview-out {
    background: none;
    -webkit-animation-name: fadeOut;
    animation-name: fadeOut;
}
.mui-preview-image.mui-preview-out .mui-preview-header,
.mui-preview-image.mui-preview-out .mui-preview-footer {
