如何在角度2组件中单击时更改布尔值

es0*_*06x 11 javascript typescript angular

如何连接按钮以更改其下方指令中[codeOnly]值的值?

我在打字稿中使用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>

在包含HTML添加的组件中

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>

  • 不太确定你的意思。`isFoo = !isFoo` 只是在每次点击事件时在 true 和 false 之间切换 isFoo。 (2认同)
