使用Angular typescript,我得到了一个json数组对象。我想删除我在收到的对象中指定的对象。但是它从来不删除它。
addCategorySub(categorySub: CategorySubModel, index: number) {
categorySub.id = categorySub.id.toString().trim();
this.categorySubService.postCategorySub(categorySub)
.subscribe({
next: (response: any) => {
//this.categorySubList.push(response.data);
//this.categorySubList = [...this.categorySubList];
this.categoryList[0].categorySubs.push({
categoryId: response.data.categoryId,
createdDate: response.data.createdDate,
id: response.data.id,
name: response.data.name,
totalCount: response.data.totalCount,
updatedDate: response.data.updatedDate
});
this.categoryList = [...this.categoryList]
},
complete: () => {
this.messageService.add({severity: 'success', summary: 'Success', detail: `${categorySub.name}.`, life: constants.TOAST_SUCCESS_LIFETIME});
this.messageService.clear('c');
//this.categoryList = this.categoryList.filter((p) => p.id !== categorySub.id).filter((p) => p.id !== undefined);
//this.categoryList[index] = this.categoryList[categorySub.id];
//delete this.categoryList[categorySub.id]
//this.categoryList = this.categoryList.filter((p) => p.categorySubs.filter((x) => x.id !== categorySub.id).splice(categorySub.id, 1));
console.log(this.categoryList)
},
error: (e) => {
this.messageService.add({severity: 'error', summary: 'Hata', detail: `not record \n${e}`, life: constants.TOAST_ERROR_LIFETIME});
this.messageService.clear('c');
}
})
}
例如,我想删除编号为27.
的数据
export class CategoryModel {
id: number | any;
name: string | any;
companyId: number | any;
createdDate: Date | undefined;
updatedDate: Date | undefined;
totalCount: number | any;
categorySubs: CategorySubModel[] = []; //any;
}
export class CategorySubModel {
id: number | any;
name: string | any;
categoryId: number | any;
createdDate: Date | undefined;
updatedDate: Date | undefined;
totalCount: number | any;
}
json对象指向categorySubs子对象。所以我想从这里删除
例如下面我有一个json对象,我想删除这个json对象中的一些选中的数据
