遍历Json数组并获取嵌套对象的值Typescript

Question

我有一个数组，可以访问要设法获取这些属性值的属性列表，但是，列表中有一个嵌套的对象“ Region ”，该对象具有特定的属性我想检索该值的“ regionName ”，请检查代码并上传图像以供参考。

我希望这有道理。预先谢谢你

  export function CreateStores(xhttp: XMLHttpRequest, storeArray?: Array<PromotionClasses.Store>) {

    while (STORE_TABLE.rows.length > 1) {
        STORE_TABLE.deleteRow(1);
    }
    if (storeArray == undefined) {

        //Convert the response into an array of objects
        storeArray = JSON.parse(xhttp.responseText) as Array<any>;
    }

   CheckForDuplicateStores(storeArray);



    //Get the current row length of the table so we know where to append to 
    let tableRowLength = STORE_TABLE.rows.length as number;
    console.log("Store array is");
 //   console.log(storesInPromotionArray);
    for (let i = 0; i < storeArray.length; i++) {

        //A dictionary containing the key value pair of the stores properties
        let tableData = {};




        //Add the store's id to the storeArray
        let store = new PromotionClasses.Store(storeArray[i]["StoreName"], storeArray[i]["id"]);

        storesInPromotionArray.push(store);
        console.log(storeArray[i]["region"]);
        var check = storeArray[i]["region"];




        //let attr = new PromotionClasses.Attribute(storeArray[i].name, storeArray[i].type, storeArray[i].property);
        //Assingattributes.push(attr);

        //Create and insert a new row

        let row = STORE_TABLE.insertRow(tableRowLength);
        //row.contentEditable = 'true'

        //The first three cells will always be the row number, store number and name
        tableData["#"] = i.toString();
        tableData["Number"] = storeArray[i]["storeNumber"];
        tableData["Name"] = storeArray[i]["storeName"];
        tableData["addressLine"] = storeArray[i]["addressLine"];
        tableData["postcode"] = storeArray[i]["postcode"];
        //****NESTED OBJECT PROPERTY = regionName
        tableData["region"] = storeArray[i]["region"];
