当我尝试在新的Class()上传递嵌套对象时,它返回空类。
我认为这是因为我传递错误的论据。
class myClass {
public selected: {
category: {
code: string
}
} = {}
}
const initialState = {
selected: {
category: {
code: ''
}
}
}
private bs: BehaviorSubject<any> = new BehaviorSubject(initialState)
这项工作很好,我给myClass带来了价值。
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: '' } } }

您需要将构造函数添加到类中,以将输入参数分配给selected
属性:
constructor(state) {
this.selected = state.selected;
}
