vue在移动端实现复制数值到剪贴版

实现按键指定内容复制到设备的剪贴版

引入clipboard.js

npm install clipboard --save

封装JS

import Vue from 'vue';
import Clipboard from 'clipboard';

function clipboardSuccess() {
  Vue.prototype.$message({
    message: '复制成功',
    type: 'success',
    duration: 1500,
  });
}

function clipboardError() {
  Vue.prototype.$message({
    message: '复制失败',
    type: 'error',
  });
}

export function handleClipboard(text, event, onSuccess, onError) {
  event = event || {};
  const clipboard = new Clipboard(event.target, {
    text: () => text,
  });
  clipboard.on('success', () => {
    onSuccess ? onSuccess() : clipboardSuccess();
    clipboard.off('error');
    clipboard.off('success');
    clipboard.destroy();
  });
  clipboard.on('error', () => {
    onError ? onError() : clipboardError();
    clipboard.off('error');
    clipboard.off('success');
    clipboard.destroy();
  });
  clipboard.onClick(event);
}

HTML

<span class="coinHttp">
    <span>{{name}}</span>
    <img   src="..//XXXX.png"   @click="copy" />
 </span>

JS

import {handleClipboard} from '../js/clipboard';
methods: {
  copy() { 
      handleClipboard(this.express.number, event, () => {
        alert('单号已经复制在剪贴版')
      }, () => {
        alert('单号复制失败！')
      })
  },
}

注:还有更简单的方法,可自行研究
