我正在尝试设置一个简单的ng-for 以循环遍历 Angular 的项目列表,但被卡住了。我已经尝试了Angular2 exception: Can't bind to 'ngFor' since it isn't a known native property 中的解决方案(修复缺少#)但没有成功。

EXCEPTION: Template parse errors:
Can't bind to 'ng-forOf' since it isn't a known native property ("<div class="ui link cards">
    <div class="card" [ERROR ->]*ng-for="#project of projects">
        <div class="image">
            <img src="project.illustrat"): Projects@1:22
Property binding ng-forOf not used by any directive on an embedded template ("<div class="ui link cards">
    [ERROR ->]<div class="card" *ng-for="#project of projects">
        <div class="image">
            <img src=""): Projects@1:4

index.js

import * as stylesheet from '../assets/styles/app.scss';

import $ from 'jquery';
import jQuery from 'jquery';
// export for others scripts to use
window.$ = $;
window.jQuery = jQuery;


import 'zone.js/lib/browser/zone-microtask';
import 'reflect-metadata';
import 'babel-polyfill';

import provide from 'angular2/core';
import bootstrap from 'angular2/platform/browser';

import App from './app.component.js'
bootstrap(App, []);

app.component.js

import Component from 'angular2/core';
import Projects from '../app/projects/projects';

@Component(
    selector: 'my-app',
    template: '<projects>Loading...</projects>',
    directives: [Projects]
)

export class App 
    constructor(projects:Projects) 
        this.projects = projects;
        console.log(this.projects);
    

index.html

<html>
<body>
    <my-app>
          <ng-content></ng-content>
    </my-app>
<script src="dist/app.js"></script>
</body>
</html>

project.js

import Component, View from 'angular2/core';
import NgFor from 'angular2/common';

@Component(
    selector: 'projects, [projects]'
)
@View(
    //templateUrl: '/app/projects/projects.html',
    directives: [NgFor],
    template: "<div *ng-for='#project of projects'> <p>project.description </div>",
)
export class Projects 
    constructor() 
        this.projects = [
            
                "customer": "Matt Giampietro",
                "description": "Lorem ipsum dolor sit amet…",
                "name": "project #1"
            ,
            
                "customer": "test",
                "description": "Lorem ipsum dolor sit amet…",
                "name": "project #2"
            
        ]
    

问题

我该如何解决这个问题? 内部/外部模板均失败( templateUrl

【问题讨论】:

正如其他人所建议的,使用 *ngFor,而不是 *ng-for 【参考方案1】:

ng-for 在最近的 Angular 版本中不正确。 模板已更改为区分大小写。现在应该是ngFor

另见Can't bind to 'ng-forOf' since it isn't a known native property
