test.ts
import { OnInit, Output} from '@angular/core';
import { Model } from './model';
@Component({
selector: 'app-test'
})
export class Test {
constructor(
public model: Model
) { }
}
模型类model.ts
import { Input } from '@angular/core';
export class Mode
我不确定我得到的错误是否:
***ERROR**: Can't bind to 'obj.Name' since it isn't a known property of 'comp'.*
是Angular不允许这种行为的结果。其目的只是绑定到@input对象属性。代码:
// comp.component.ts
...
@Input() obj: ObjType = {
Name: ''
}
// comp2.html
...
// this HTML is passing the value from comp2.html
我创建了一个示例项目,在其中我使用了组件,一个带有注册名,另一个具有登录名,同时验证注册页面,给出下面提到的错误。
当表单验证时,错误发生。

当我尝试使用@click指令更改某个属性的值时,会收到此警告:
[Vue warn]: Avoid mutating a prop directly since the value will be overwritten whenever the parent component re-renders. Instead, use a data or computed property based on the prop's value. Prop being mutated: "name"
我的代码如下:
