vue+element ui 重置表單

<el-dialog :title="addForm.title" :visible.sync="dialogFormVisible" width="900px" @close="closeDialog">
    <el-form :model="addForm" :rules="rules" ref="addForm" label-width="100px" class="demo-ruleForm">
　　 </ el-form>   
</el-dialog> 

methods:{
  closeDialog(){
        //關閉時表單重置表單
        this.$refs.addForm.resetFields();
      }      
}

form 表單里 model和addForm的值一定要一致！！來自小白的...
