如何在打字稿中的对象数组中获取特定值

Question

我有一个对象数组，我使用 *ngfor 循环并显示在 ngdropdownmenu 中。我选择一个并返回一个包含名称和操作的对象并将其分配给字符串变量。 如何在打字稿中只获取所选对象的动作值？

//Typescript Code:
specificaction: string = "";
public finishActions = [
{ name: "blah", action: "blahblahblah" },
{ name: "blah", action: "blahblahblah" },
{ name: "blah", action: "blahblahblah" },
{ name: "blah", action: "blahblahblah" },
{ name: "blah", action: "blahblahblah" },
{ name: "", action: "" }
] 
finishAction(action: string) {
this.specificaction= action;
//I CAN NOT GET THE specification.action
console.log(this.specificaction.action);
 }

//HTML
<div ngbDropdownMenu aria-labelledby="dropdownBasic1">
  <button class="dropdown-item text-right" *ngFor="let action of 
finishActions" (click)="finishAction(action)">{{action.name}}</button>
</div>

Answer 1

我会这样做：

<div *ngFor="let finishAction of finishActions">
    <p>{{ finishAction.action }}</p>
</div>
