在Angular 2中创建通用列表迭代器

Question

I want to wrap a list of items, but I want the flexibility of supplying a unique template.

<list [items]="someItems">
    <book-list-item><!-- Books, cars, dogs, whatever -->
    </book-list-item><!-- This will contain a unique template -->
</list>

ListItemComponent

import { Component, Input } from '@angular/core';

@Component({
    selector: 'list-item',
    template: `
        <div *ngFor="let item of items">
            <ng-content></ng-content><!-- Whatever book-list-item contains -->
        </div>`
})
export class ListItemComponent {
    @Input() items: Array<any>;
}

BookListItemComponent

import { Component } from '@angular/core';

@Component({
    selector: 'book-list-item',
    template: `
        <div class="row">
            <div class="col-xs-6">Books</div>
            <div class="col-xs-6">Rule</div>
        </div>`

})
export class BookListItemComponent {}

Obviously I'd be passing books as items , but this is just an example. I can get something similar to this working, but "Books Rule" only prints out in the last list-group-item (because Bootstrap).

I'm really looking to understand how to pass a generic component to parent component that will iterate over the generic component as an item in a list of items. Can someone point me in the right direction?

Take a look at this article . It does something very similar to what you need. Your main challange will be binding the values. You can also Look at Ben Nadel's article . It relates to RC1 and even he in the comments mentions that the setLocal is not there anymore and that you need to pass the context.
