Question

这是FileObject的构建方式，我需要帮助来确定如何根据提供的日期进行迭代和查找值。

    interface MyProps{
      date: string;
      cDataFileName?: string | undefined;
      iDataFileName?: string | undefined;
    }

在开发工具中，它显示如下。

 FileObject: Array(4)
0: {date: "8/26/2020", cDataFileName: : "small_range_c-compressed.json", influenzaDataFileName: "mall_range_f-compressed.jso"}
1: {date: "8-24-2020", cDataFileName: : "small_range_c-compressed.json", iDataFileName: : "mall_range_f-compressed.jso"}
2: {date: "8-13-2020", cDataFileName: : "small_range_c-compressed.json", iDataFileName: : "mall_range_f-compressed.jso"}
3: {date: "7-15-2020", cDataFileName: : "small_range_c-compressed.json", iDataFileName: : "mall_range_f-compressed.jso"}
length: 4

我需要做的是查找FileObject数据中是否存在日期为“ 8/26/2020”的时间

并为其获取cDataFileName和IDataFileName值。

const today = "8/26/2020";
  console.log("testing" + FileObject [today as any]);  // Its coming as testingUndefined.
  if (today in FileObject ) {
    console.log("today" + today);  // Not even going there
  }

请帮助我找出一种最佳方法，以根据提供的日期“ 8/26/2020”来遍历此对象数组。

----------更新1 ---------- 这就是我将值赋给FileObject的方式。

const FileObject: MyProps[] = [];

     FileObject.push({
                date: file,
                cDataFileName: MycovidFileName,
                iDataFileName: MyinDataFileName,
              });

这与打字稿或反应无关...

只需FileObject.find(obj => obj.date === "8/26/2020");

React：遍历对象数组
