如果app的项目在运行中出现上面的问题，可以检查一下自己获取数据方法中，是否用延展运算符；

一般是延展运算符使用出了错误，例如在一个对象前面用了延展运算符。

// 获取子组件点击了搜索/确定返回来的数据
    async handleConfirm(value) {
		console.log('搜索框返回数据',value)
      if (!value) {
        return
      }

      const { data } = await getPurWarehouse(
			JSON.stringify({
			  vouchCode: value,
			})
      )	
	  // 展示数组为默认数组,避免渲染发生卡顿.设置700 ms的防抖
	  this.SupplierInfo = [...this.detailList]
      //上面这句👆
    },
