Vue使用Clipboard.JS在h5页面中复制内容

• 安装clipboard.js
  
  github路径:https://github.com/zenorocha/clipboard.js
  
  安装：
  
  npm install clipboard --save

• 引入clipboard.js

import ClipboardJS from "clipboard";

或

<script src="https://clipboardjs.com/dist/clipboard.min.js"></script>

• 使用：

1. 剪切

<html xmlns="http://www.w3.org/1999/xhtml">

<head>
    <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0, minimum-scale=1.0, maximum-scale=1.0, user-scalable=no" />
    <meta name="apple-mobile-web-app-capable" content="yes">
    <meta name="apple-mobile-web-app-status-bar-style" content="black">
    <meta name="format-detection" content="telephone=no">
    <title>dfsf</title>

    <script src="https://clipboardjs.com/dist/clipboard.min.js"></script>
    <script src="https://apps.bdimg.com/libs/jquery/2.1.4/jquery.min.js"></script>
    <script>
        $(function() {
            new ClipboardJS('.btn');
        })
    </script>
</head>

<body>
    <div>
        <!-- Target -->
        <textarea id="bar">Mussum ipsum cacilds...</textarea>

        <!-- Trigger -->
        <button class="btn" data-clipboard-action="cut" data-clipboard-target="#bar">
    Cut to clipboard
</button>

    </div>

</body>

</html>

1. 复制

 <button class="btn" data-clipboard-action="copy" data-clipboard-target="#bar">

3.在vue中使用并自定义复制内容，定义复制回调：

<div class="dlbtn cpkw" @click="copykeyword">复制关键词</div>

·····
copykeyword() {
      var clipboard = new ClipboardJS(".cpkw", {
        text: function(trigger) {
          //alert("ok");
          return "testvalue";
        }
      });
      clipboard.on("success", e => {
        //复制成功
        // 释放内存
        clipboard.destroy();
      });
      clipboard.on("error", e => {
        // 不支持复制
         console.log("该浏览器不支持自动复制");
        // 释放内存
        clipboard.destroy();
      });
