在 intanciate 上传递嵌套对象 class

Pass nested object on intanciate class

当我尝试在新 Class() 上传递嵌套对象时,它 returns 为空 class。

我想是因为我传递了错误的论点。

class myClass {
    public selected: {
        category: {
            code: string
        }
    } = {}
}

const initialState = {
    selected: {
        category: {
            code: ''
        }
    }
}

private bs: BehaviorSubject<any> = new BehaviorSubject(initialState)

这很好,我得到了我的Class值。

但是当我想在之后传递值时:

setCategory (myCategory) {
    let value = this.bs.getValue();
    let newValue = Object.assign({}, value, {
                    selected: {
                        category:{
                            code: myCategory
                        }
                    }
                });
     new myClass(newValue) // return { view: {}, selected: { category: { code: '' } } }
}

我得到{ view: {}, selected: { category: { code: '' } } }

更新

实时代码:https://stackblitz.com/edit/angular-bjlhus?file=app%2Fapp.component.ts

您需要将构造函数添加到您的 class 以将输入参数分配给 selected 属性:

constructor(state) {
    this.selected = state.selected;
}
