我已经扩展了FilterMetaData
类型,以添加一个动态模型,该模型对于不同的实体而言是不同的结构,但是某种程度上打字稿无法识别我的对象属性。我可能在这里错过了一些东西。
界面
export type FilterMetaData<T extends {}> = T & {
filterCriteriaID: number;
filterCriteriaName?: string;
isDefaultSelected?: boolean;
isExpanded?: boolean;
}
export interface DateRange {
data?: DateRangeData;
}
export interface DateRangeData {
min?: Date;
max?: Date;
}
export interface Range {
data?: RangeData;
}
export interface RangeData {
currency?: string;
timePeriod?: string;
min?: number;
max?: number;
step?: number;
}
export interface Select {
data?: SelectData[];
}
export interface SelectData {
id?: number;
name?: string;
isSelected?:boolean|false;
parentID?: number | null;
parentName?: string;
}
课堂实施
helper<T1 extends FilterMetaData<T2>>(filter) {
this.selectedFilterService.getAppliedFilterMasterData<T1>(filter)
.pipe(takeUntil(this.unsubscribe$))
.subscribe((filterData: T1) => {
if (filter.isDefaultSelected) {
filterData.isExpanded = false;
filterData.data.forEach((data) => data.isSelected = false);
this.selectedFilters.result.select.push(filterData);
this.loadComponent(new FilterComponentType(SelectComponent, filterData));
} else {
this.removeComponent(filter);
}
}, err => {
this.toastrService.error(err);
})
}
使用args类型调用函数,如下所示:-
this.helper<FilterMetaData<Select>>(filter);
