如何使用鍵和值將對象更新為javascript，typescript中的數組

Question

我有一個名為dropdowns的對象，具有鍵值對的對象。我想更新名為dropdowns的對象。如何更新該對象。請幫助我。

dropdowns: any = {};

dropdowns={
           clientCode: ["ALDR","NIKE"], 
           carrierCode: ["XYZ","ABC","DEF","GHI"], 
           invoiceCount: [123,456,789]
          }

我想使clientCode：[“ LMN”，“ OPQ”，“ RST”，“ UVW”]如何更新對象。

Answer 1

dropdowns.clientCode = ["LMN","OPQ","RST","UVW"];

Answer 2

您只需要使用“。”（點）運算符訪問下拉對象，然后按照您說的“ clientCode”選擇要更新的密鑰，然后執行以下操作：

//objectname.key = newvalue; -- syntax
dropdown.clientCode = ["LMN","OPQ","RST","UVW"];
