[英]How to change boolean value on click in angular 2 component
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>
