vue + element-ui + clipboard.js 实现复制、粘贴功能

// 只需要很简单的两步
npm install
npm run serve

// 0.复制选项 html 准备（参考官方文档了解配置项）
    <p>原样复制指定文本框内容</p>
    <div class="row">
      <textarea id="bar">Mussum ipsum cacilds...</textarea>
      <el-button
        class="copyBtn"
        data-clipboard-action="copy"
        data-clipboard-target="#bar"
        icon="el-icon-copy-document"
      >Copy</el-button>
    </div>
    
    <p>点击复制自定义内容到剪切板</p>
    <div class="row">
      <el-button
        class="copyBtn"
        data-test="test..."
        :data-clipboard-text="diyContent"
        icon="el-icon-copy-document"
      >Copy</el-button>
    </div>

// 1.需要用到的地方引入 Clipboard
import Clipboard from 'clipboard'

// 2.用触发操作对象实例化一个 clipboard 对象
var clipboard = new Clipboard(".copyBtn");

// 3.为其指定操作成功回调函数
var that = this
clipboard.on("success", function (e) {
    console.info("Action:", e.action);
    console.info("Text:", e.text);
    console.info("Trigger:", e.trigger);

    // 清除选中状态
    e.clearSelection();

    that.$notify({
        title: '成功',
        message: '恭喜您复制成功，赶快去粘贴吧~',
        type: 'success',
        showClose: false
    });
});

// 4.为其指定操作失败回调函数
clipboard.on("error", function (e) {
    console.error("Action:", e.action);
    console.error("Trigger:", e.trigger);

    that.$notify.error({
        title: '失败',
        message: '操作失败，请重试！',
        showClose: false
    });
