Javascript 带TS的角度2 ES6滤波器
我无法使ES6过滤器功能与Angular 2(带TypeScript)一起工作 我的筛选函数如下所示:Javascript 带TS的角度2 ES6滤波器,javascript,angular,typescript,Javascript,Angular,Typescript,我无法使ES6过滤器功能与Angular 2(带TypeScript)一起工作 我的筛选函数如下所示: getApplicableNotes(): void { this.noteService .getNotes() .then(notes => { notes.filter((note) => !note._deleted && !note._done); this.notes = notes; }) .catch((error)
getApplicableNotes(): void {
this.noteService
.getNotes()
.then(notes => {
notes.filter((note) => !note._deleted && !note._done);
this.notes = notes;
})
.catch((error) => this.error = error);
}
我的TypeScript类非常简单:
export class Note {
id: number;
title: string;
description: string;
_starred = false;
_done = false;
_deleted = false;
constructor(id: number, title: string, description: string, starred?: boolean, done?: boolean, deleted?: boolean) {
this.id = id;
this.title = title;
this.description = description;
this._starred = starred ? starred : false;
this._done = done ? done : false;
this._deleted = deleted ? deleted : false;
};
}
尽管如此,我的notes数组从未被过滤,无论我将在notes构造函数中设置什么属性。该方法不会修改数组,而是返回一个新的过滤数组。您应该将结果分配给此。注意:
.then(notes => {
this.notes = notes.filter((note) => !note._deleted && !note._done);
})
该方法不修改数组,但返回一个新的筛选数组。您应该将结果分配给此。注意:
.then(notes => {
this.notes = notes.filter((note) => !note._deleted && !note._done);
})
