由于不带参数的fill()方法(在已接受的答案中提到过)会抛出错误，我建议这样做(对我有用，Angular 7.0.4, Typescript 3.1.6)

<div class="month" *ngFor="let item of items">
...
</div>

在组件代码中:

this.items = Array.from({length: 10}, (v, k) => k + 1);

使用自定义结构指令索引:

根据Angular文档:

createEmbeddedView Instantiates an embedded view and inserts it into this container. abstract createEmbeddedView(templateRef: TemplateRef, context?: C, index?: number): EmbeddedViewRef. Param Type Description templateRef TemplateRef the HTML template that defines the view. context C optional. Default is undefined. index number the 0-based index at which to insert the new view into this container. If not specified, appends the new view as the last entry.

当angular通过调用createEmbeddedView创建模板时，它也可以传递将在ng-template中使用的上下文。

使用context可选参数，你可以在组件中使用它， 在模板中提取它，就像你使用*ngFor一样。

app.component.html:

<p *for="number; let i=index; let c=length; let f=first; let l=last; let e=even; let o=odd">
  item : {{i}} / {{c}}
  <b>
    {{f ? "First,": ""}}
    {{l? "Last,": ""}}
    {{e? "Even." : ""}}
    {{o? "Odd." : ""}}
  </b>
</p>

for.directive.ts:

import { Directive, Input, TemplateRef, ViewContainerRef } from '@angular/core';

class Context {
  constructor(public index: number, public length: number) { }
  get even(): boolean { return this.index % 2 === 0; }
  get odd(): boolean { return this.index % 2 === 1; }
  get first(): boolean { return this.index === 0; }
  get last(): boolean { return this.index === this.length - 1; }
}

@Directive({
  selector: '[for]'
})
export class ForDirective {
  constructor(private templateRef: TemplateRef<any>, private viewContainer: ViewContainerRef) { }

  @Input('for') set loop(num: number) {
    for (var i = 0; i < num; i++)
      this.viewContainer.createEmbeddedView(this.templateRef, new Context(i, num));
  }
}

我无法忍受为组件的简单重复分配数组的想法，所以我写了一个结构指令。在最简单的形式中，这并没有使索引对模板可用，它看起来像这样:

import { Directive, Input, TemplateRef, ViewContainerRef } from '@angular/core';

@Directive({ selector: '[biRepeat]' })
export class RepeatDirective {

  constructor( private templateRef: TemplateRef<any>,
             private viewContainer: ViewContainerRef) { }

  @Input('biRepeat') set count(c:number) {
    this.viewContainer.clear();
    for(var i=0;i<c;i++) {
      this.viewContainer.createEmbeddedView(this.templateRef);
    }
  }
}

在你的组件中，你可以定义一个number (ES6)数组，如下所示:

export class SampleComponent {
  constructor() {
    this.numbers = Array(5).fill().map((x,i)=>i); // [0,1,2,3,4]
    this.numbers = Array(5).fill(4); // [4,4,4,4,4]
  }
}

查看这个链接来创建数组:用最简洁的方法从1..JavaScript 20。

然后你可以用ngFor迭代这个数组:

@Component({
  template: `
    <ul>
      <li *ngFor="let number of numbers">{{number}}</li>
    </ul>
  `
})
export class SampleComponent {
  (...)
}

或:不久

@Component({
  template: `
    <ul>
      <li *ngFor="let number of [0,1,2,3,4]">{{number}}</li>
    </ul>
  `
})
export class SampleComponent {
  (...)
}

由于不带参数的fill()方法(在已接受的答案中提到过)会抛出错误，我建议这样做(对我有用，Angular 7.0.4, Typescript 3.1.6)

<div class="month" *ngFor="let item of items">
...
</div>

在组件代码中:

this.items = Array.from({length: 10}, (v, k) => k + 1);

你也可以用like that

export class SampleComponent {
   numbers:Array<any> = [];
   constructor() {
      this.numbers = Array.from({length:10},(v,k)=>k+1);
   }
}

HTML

<p *ngFor="let i of numbers">
   {{i}}
</p>
