vue实现复制粘贴的两种形式

方式一：

1.安装clipboard:npm install clipboard

2.src/utils/clipboard.js

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

function clipboardSuccess() {
  console.log('success')
  Vue.prototype.$message({
    message: 'Copy successfully',
    type: 'success',
    duration: 1500
  })
}

function clipboardError() {
  console.log('error')
  Vue.prototype.$message({
    message: 'Copy failed',
    type: 'error'
  })
}

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

3.vue代码

<template>
    <div class="app-container">
      <el-tabs>
       <el-tab-pane label="直接使用剪切板">
         <div class="el-tab-pane" >
           <el-input   v-model="inputData"    style='400px;'></el-input>
           <el-button    @click="handleCopy(inputData,$event)">复制</el-button>
         </div>
       </el-tab-pane>
      </el-tabs>
    </div>
</template>
<script>
  import clip from '@/utils/clipboard'
  export default {
        name: "index",
        data(){
          return {
            inputData:""
          }
        },
      methods:{
        handleCopy(text, event) {
          clip(text, event)
          console.log('clicp')
        }
      }
    }
</script>

<style scoped>

</style>



<el-tab-pane label="使用封装的剪切指令v-directive">
  <div class="el-tab-pane" >
    <el-input     style='400px;'></el-input>
    <el-button>复制</el-button>
  </div>
</el-tab-pane>

方式二：src/directive/clipboard/clipboard.js

               src/directive/clipboard/index.js

              npm install clipboard --save

          

//index.js
import Clipboard from './clipbloard'

const install = function(Vue) {
  Vue.directive('Clipboard', Clipboard)
}

if (window.Vue) {
  window.clipboard = Clipboard
  Vue.use(install); // eslint-disable-line
}

Clipboard.install = install
export default Clipboard

//clipboard.js
// Inspired by https://github.com/Inndy/vue-clipboard2
const Clipboard = require('clipboard')
if (!Clipboard) {
  throw new Error('you shold npm install `clipboard` --save at first ')
}

export default {
  bind(el, binding) {
    if (binding.arg === 'success') {
      el._v_clipboard_success = binding.value
    } else if (binding.arg === 'error') {
      el._v_clipboard_error = binding.value
    } else {
      const clipboard = new Clipboard(el, {
        text() { return binding.value },
        action() { return binding.arg === 'cut' ? 'cut' : 'copy' }
      })
      clipboard.on('success', e => {
        const callback = el._v_clipboard_success
        callback && callback(e) // eslint-disable-line
      })
      clipboard.on('error', e => {
        const callback = el._v_clipboard_error
        callback && callback(e) // eslint-disable-line
      })
      el._v_clipboard = clipboard
    }
  },
  update(el, binding) {
    if (binding.arg === 'success') {
      el._v_clipboard_success = binding.value
    } else if (binding.arg === 'error') {
      el._v_clipboard_error = binding.value
    } else {
      el._v_clipboard.text = function() { return binding.value }
      el._v_clipboard.action = function() { return binding.arg === 'cut' ? 'cut' : 'copy' }
    }
  },
  unbind(el, binding) {
    if (binding.arg === 'success') {
      delete el._v_clipboard_success
    } else if (binding.arg === 'error') {
      delete el._v_clipboard_error
    } else {
      el._v_clipboard.destroy()
      delete el._v_clipboard
    }
  }
}
