使用方法:

1. 下载文件

官方项目地址:https://github.com/thdoan/magnify

或者这里下载,只保留了需要的文件:码云地址
需要用到 assets 文件夹里的css和js

2. html

data-src 是大图链接 这里可以不用添加data-src属性,后面可以用jq追加

<img data-src="" src="">

3. css

  <!-- bootstrap -->
  <link href="https://cdn.bootcss.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet">
  <!-- magnify -->
  <link href="./assets/css/jquery.magnify.min.css" rel="stylesheet">
  <!-- 阿里图标 -->
  <link rel="stylesheet" href="https://at.alicdn.com/t/font_1576642_nvbefyzwm6.css">
  <style>
    .magnify-modal {
      box-shadow: 0 0 20px rgba(0, 0, 0, 0.25) !important;
      overflow: hidden;
    }

    .magnify-header .magnify-toolbar {
      background-color: rgba(0, 0, 0, 0.5) !important;
    }

    .magnify-stage {
      top: 0 !important;
      right: 0 !important;
      bottom: 0 !important;
      left: 0 !important;
      border-width: 0 !important;
    }

    .magnify-footer .magnify-toolbar {
      background-color: rgba(0, 0, 0, 0.5) !important;
      border-top-left-radius: 5px !important;
      border-top-right-radius: 5px !important;
    }

    .magnify-header,
    .magnify-footer {
      pointer-events: none !important;
    }

    .magnify-button {
      pointer-events: auto !important;
    }

    .magnify-toolbar.magnify-head-toolbar {
      background: none !important;
    }

    .magnify-toolbar.magnify-head-toolbar>button {
      border-radius: 100% !important;
      background: rgba(0, 0, 0, 0.5);
      margin: 5px 5px 0 0 !important;
    }

    .magnify-toolbar.magnify-foot-toolbar {
      border-radius: 50px !important;
    }

    .magnify-modal i {
      font-size: 20px;
    }

    .magnify-footer .magnify-toolbar {
      padding: 0 10px;
