通用指令(directives)

1、clipboard 粘贴指令

<template>
    <div>
    <el-input v-model="inputData" placeholder="Please input" style="width:400px;max-width:100%;" />
 <el-button v-clipboard:copy="inputData" v-clipboard:success="clipboardSuccess" type="primary" icon="el-icon-document">
          copy
        </el-button>
    </div>
</template>

<script>
import clipboard from '@/directive/clipboard/index.js' // use clipboard by v-directive
export default {
  name: 'ClipboardDemo',
  directives: {
    clipboard
  },
  data() {
    return {
      inputData: 'https://www.baidu.com'
    }
  },
  methods: {
    clipboardSuccess() {
      this.$message({
        message: 'Copy successfully',
        type: 'success',
        duration: 1500
      })
    }
  }
}
</script>

2、el-drag-dialog 拖动弹窗

封装了一个指令拖动弹窗,能简单快速的实现弹窗的拖动。 v-el-drag-dialog

<template>
  <div class="components-container">
    <el-button type="primary" @click="dialogTableVisible = true">
      open a Drag Dialog
    </el-button>
    <el-dialog v-el-drag-dialog :visible.sync="dialogTableVisible" title="Shipping address" @dragDialog="handleDrag">
      <el-select ref="select" v-model="value" placeholder="请选择">
        <el-option v-for="item in options" :key="item.value" :label="item.label" :value="item.value" />
      </el-select>
      <el-table :data="gridData">
        <el-table-column property="date" label="Date" width="150" />
        <el-table-column property="name" label="Name" width="200" />
        <el-table-column property="address" label="Address" />
      </el-table>
    </el-dialog>
  </div>
</template>

<script>
import elDragDialog from '@/directive/el-drag-dialog' // base on element-ui
export default {
  name: 'DragDialogDemo',
  directives: { elDragDialog },
  data() {
    return {
      dialogTableVisible: false,
      options: [
        { value: '选项1', label: '黄金糕' },
        { value: '选项2', label: '双皮奶' },
        { value: '选项3', label: '蚵仔煎' },
        { value: '选项4', label: '龙须面' }
      ],
      value: '',
      gridData: [{
        date: '2016-05-02',
        name: 'John Smith',
        address: 'No.1518,  Jinshajiang Road, Putuo District'
      }, {
        date: '2016-05-04',
        name: 'John Smith',
        address: 'No.1518,  Jinshajiang Road, Putuo District'
      }, {
        date: '2016-05-01',
        name: 'John Smith',
        address: 'No.1518,  Jinshajiang Road, Putuo District'
      }, {
        date: '2016-05-03',
        name: 'John Smith',
        address: 'No.1518,  Jinshajiang Road, Putuo District'
      }]
    }
  },
  methods: {
    // v-el-drag-dialog onDrag callback function
    handleDrag() {
      this.$refs.select.blur()
    }
  }
}

3、permission 权限指令

封装了一个指令权限,能简单快速的实现按钮级别的权限判断。 v-permission

<template>
  <!-- Admin can see this -->
  <el-tag v-permission="['admin']">admin</el-tag>

  <!-- Editor can see this -->
  <el-tag v-permission="['editor']">editor</el-tag>

  <!-- Editor can see this -->
  <el-tag v-permission="['admin','editor']">Both admin or editor can see this</el-tag>
</template>

<script>
// 当然你也可以为了方便使用,将它注册到全局
import permission from '@/directive/permission/index.js' // 权限判断指令
export default{
  directives: { permission }
}
</script>

4、pinyin 汉字转拼音

5、repeat-click 重复点击指令
