elementui form resetFields()方法的使用

    <el-form :span="18" :model="dataForm" :rules="dataRule" ref="dataFormRef" @keyup.enter.native="dataFormSubmit()" label-width="80px">






//必须放到$nextTick() dom渲染完之后执行resetFields，否则为undefined
this.$nextTick(() => {
        this.$refs.dataFormRef.resetFields()
      })
