我們如何在打字稿中向物件陣列插入值？
我想將 1993 年的值插入到示例物件上的每個 yearRentCurrent 值中。
所以每個yearRentCurrent 值現在都是1993 年。有什么想法嗎？. 我們如何在 typescript 或 angular 中解決這個問題？謝謝。
#data 我想插入
this.transaction.propertyDto.propertyDetailDto.annualRentUsd = 1993;
#sample 物件
this.data.object = [

uj5u.com熱心網友回復：
由于您只想為陣列中的所有元素設定相同的值，您可以使用map：
this.data.object.map(o => o.annualRentCurrent = 1993);
或forEach：
this.data.object.forEach(o => o.annualRentCurrent = 1993);
它們在這種情況下基本相同，但map會回傳一個新陣列（在這種情況下也會改變原始陣列），而 forEach 只是迭代原始陣列中的每個元素。
