element-ui的el-form验证和el-dialog关闭时清除验证

在这里插入代码片
        <div class="dialog">
          <el-dialog
            @close="closeDialog('ruleForm')"
            :title="`${title}`+'字段'"
            :visible.sync="dialogFormVisible"
            :close-on-press-escape="false"
            :close-on-click-modal="false">
             <el-form
              :model="addFieldForm"
              label-width="120px"
              :rules="rules"
              ref="ruleForm">
	// 关闭弹窗
	  closeDialog (formRule) {
      this.$refs[formRule].resetFields()
    },
