vue中单独封装elementui中的Dialog弹框组件

一。在components文件中新建 弹框组件

<template>
  <div>
    <el-dialog title="提示" :visible.sync="dialogVisible" width="30%" @close="handleClose">
      <span>这是一段信息</span>
      <span slot="footer" class="dialog-footer">
        <el-button @click="dialogVisible = false">取 消</el-button>
        <el-button type="primary" @click="dialogVisible = false">确 定</el-button>
      </span>
    </el-dialog>
  </div>
</template>
<script>
export default {
  props:{
    DialogFlag: {
      default: false
    }
  },
  data(){
    return{
      dialogVisible: false
    }
  },
  watch:{
    DialogFlag(){
      this.dialogVisible = this.DialogFlag
    }
  },
  methods:{
    handleClose() {
       this.$emit('update:DialogFlag',false)
    }
  },

}
</script>

二。在需要用到的组件中引入子组件

<account-inform-add :DialogFlag.sync="DialogFlag"></account-inform-add>

methods: {

    addAccountInform(){

      this.DialogFlag = true

    }

  }
