javascript - 如何在 Angular 2 组件中单击时更改 bool 值

Question

如何连接按钮以更改其下方指令中 [codeOnly] 值的值？

我在 typescript 中使用 Angular 2.4.10。

<button class="btn btn-primary">
     Click me to change all of the [codeOnly] values below to true
</button>

<app-header [codeOnly]='false'></app-header>

<app-power-bi-wrapper [codeOnly]='false'></app-power-bi-wrapper>

<app-power-bi-wrapper-mobile [codeOnly]='false'></app-power-bi-wrapper-mobile>

<app-page-title [codeOnly]='false'></app-page-title>

<app-page-title-nav [codeOnly]='false'></app-page-title-nav>

Answer 1

在包含您的 HTML 的组件中添加

isFoo:boolean = false;

然后将 HTML 更改为

<button class="btn btn-primary" (click)="isFoo = true" >
     Click me to change all of the [codeOnly] values below to true
</button>

<app-header [codeOnly]='isFoo'></app-header>

<app-power-bi-wrapper [codeOnly]='isFoo'></app-power-bi-wrapper>

<app-power-bi-wrapper-mobile [codeOnly]='isFoo'></app-power-bi-wrapper-mobile>

<app-page-title [codeOnly]='isFoo'></app-page-title>

<app-page-title-nav [codeOnly]='isFoo'></app-page-title-nav>

或切换

<button class="btn btn-primary" (click)="isFoo = !isFoo" >
     Click me to change all of the [codeOnly] values below to true
</button>
