输入修饰符用于从父级到子级的通信。这就是我们在父组件中编写的内容。
1. ParentComponentCode
<h1>Parent Component HTML part</h1>
<app-child [childVariable] = "parentvariable"></app-child>
//Parent.ts
export class ParentComponent implements OnInit {
parentvariable = "Hello Child";
constructor() { }
}
2. ChildComponentCode
@Component({
selector: 'app-child',
template: '<div>
<h3>I am inside child component.</h3>
</div>',
})
export class ChildComponent implements OnInit {
@Input() childVariable;
constructor() { }
}
因此,在上面的代码中,我们在父组件中使用了子组件指令。这意味着在父组件中,子模板的所有html内容都会按原样反映。这意味着父组件中的行将在父组件的控制台中显示我在子组件中。。 所以输出将是这样
父组件HTML部分
我在孩子里面 组件。
我的问题是,我们可以采取任何方式来使用此@input装饰器,以便将值从父级传递到子级。 在我的代码中,我的子组件html部分是一个非常长且复杂的代码。 所以,如果我在父组件中使用该子选择器,则整个子组件视图都将打印在父组件内部,这不是我的目标。 我只想将值从父母传递给孩子。帮帮我。
