Vue使用el-dialog关闭后重置表单方式

resetForms(formName) {
   this.$refs[formName].resetFields();
}

this.$nextTick(() => {
   this.$refs.formData.clearValidate();
});

    <el-dialog :title="title" :visible.sync="open" width="500px" append-to-body>
      <el-form ref="form" :model="form" :rules="rules" label-width="80px">
        <el-form-item :label="title + '原因'" prop="reason">
          <el-input
            v-model="form.reason"
            :placeholder="'请输入' + title + '原因'"
          />
        </el-form-item>
      </el-form>
      <div slot="footer" class="dialog-footer">
        <el-button type="primary" @click="submitForm">确 定</el-button>
        <el-button @click="cancel">取 消</el-button>
      </div>
    </el-dialog>

      // 弹出层标题
      title: "",
      // 是否显示弹出层
      open: false,
      // 表单参数
      form: {},
      // 表单校验
      rules: {
        reason: [
          { required: true, message: "参数名称不能为空", trigger: "blur" }
        ],
      },

    // 表单重置
    reset() {
      this.resetForm("form");
    },
     /** 提交按钮 */
    submitForm: function () {
      this.$refs["form"].validate((valid) => {
        if (valid) {
          //提交保存
        }
      });
    },
    // 取消按钮
    cancel() {
      this.open = false;
      this.reset();
    },
