我在设置Input属性时遇到问题。我想要做的是传递app.component.ts中的值passBool并设置属性的下一个组件称为receivedBool。@Input不工作Angular 2
这里是我的代码:
app.component.ts
import { Component } from '@angular/core';
@Component({
selector: 'my-app',
template: `
<nextComponent [receivedBool]="passBool"></nextComponent>
`
})
export class AppComponent {
//Variables
passBool: Boolean = true;
constructor(){
console.log('The boolean value we are trying to pass is: ' + this.passBool)
}
}
nextComponent.component.ts
import { Component, Input } from '@angular/core';
@Component({
selector: 'nextComponent',
template: `<i> </i> `
})
export class NextComponent {
@Input() receivedBool: Boolean = false;
constructor() {
console.log('The boolen value we are receiving here is: ' + this.receivedBool)
}
}
控制台日志的结果是:
The boolean value we are trying to pass is: true
- app.component.ts
The boolean value we are receiving here is: false
- nextComponent.component.ts
我希望你能赐教。谢谢!
谢谢你,帮我想通休息了! –
角度在运行时只读取属性值只在编译时,检查此答案https://stackoverflow.com/questions/39614451/angular-2-input-binding-does-not-work/39614592#39614592 – kelgwiin
