将AngularJS绑定升级到Angular2

将AngularJS控制器升级到Angular2

export default {
    template: html,
    bindings: {
        binding1: '<',
        binding2: '<',
        binding3: '<'
    },
    controller: [SomeService, controller]
}

function controller(SomeService) {
    // code
}

如何替换绑定

@Component({
    template: html,
    selector: 'wasnt-shown-in-ngJS-example',
})
export class TestComponent {
    @Input() binding1: number;
    @Input() binding2: string;
    @Input() binding3: Foobar | null;

    constructor(private someSrv: SomeService){
    }

}

这就是你要找的吗

我尝试执行相同的操作，但绑定值未定义。它们将在构造函数中未定义，但首先在ngOnInit（）函数中具有值。如果不是，请检查父元素及其语法。特别是烤肉串案与骆驼案的问题。

@Component({
    template: html,
    selector: 'wasnt-shown-in-ngJS-example',
})
export class TestComponent {
    @Input() binding1: number;
    @Input() binding2: string;
    @Input() binding3: Foobar | null;

    constructor(private someSrv: SomeService){
    }

}
