Good day Developers in the house.
好日子开发商在房子里。 I am new in Angular.我是 Angular 的新手。 I want to send all selected values from a Json string coming from API to my Database.我想将来自 API 的 Json 字符串中的所有选定值发送到我的数据库。 I have tried converting the Json string to Array and use ForEach to loop over the Array and equating it to the each of the models but is not working.我尝试将 Json 字符串转换为 Array 并使用 ForEach 循环遍历 Array 并将其等同于每个模型，但无法正常工作。 This is the format of my Json string这是我的 Json 字符串的格式

I want to get all the debit, Credit and Trans-Date from the Json and send to database.我想从 Json 中获取所有借方、贷方和 Trans-Date并发送到数据库。 I have tried converting to Array using Object.entries() and then loop through the Array as follows:我尝试使用Object.entries()转换为数组，然后按如下方式循环遍历数组：
this.results.forEach(a => {
let postItem: CreateDto = new CreateDto();
postItem.transactionDate = a.trans_date;
postItem.AmountCR = a.credit;
postItem.AmountDR = a.debit
});
this._Apservices.CreateItem(postItem).pipe(finalize(()=>{this.saving = false;})).subscribe();
But is not picking any values on a.trans_date, a.credit, a.debit as is saying undefined as the value on Console when i console.log it.. Please what is the better way to do this.但是没有在a.trans_date、a.credit、a.debit上选择任何值，正如我在 console.log 时所说的未定义为控制台上的值。请问有什么更好的方法来做到这一点。 I need help Developers我需要帮助开发者

Maybe you are having a problem with asynchronous calls, that code may be executed before the API's request was completed so you are getting undefined values.也许您遇到了异步调用的问题，该代码可能在 API 的请求完成之前执行，因此您得到未定义的值。 If that's the case I suggest you lookup Promises or Callbacks.如果是这种情况，我建议您查找 Promises 或 Callbacks。 Can you provide the API's call from which you get this.results您能否提供从中获取 this.results 的 API 调用
