angular - Repeat HTML element multiple times using ngFor based on a number -


how use *ngfor repeat html element multiple times?

for eg: if have member variable assigned 20. how use *ngfor directive make div repeat 20 times?

you use following:

@component({   (...)   template: `     <div *ngfor="let of arr(num).fill(1)"></div>   ` }) export class somecomponent {   arr = array; //array type captured in variable   num:number = 20; }

or implement custom pipe:

@pipe({   name: 'fill' }) export class fillpipe implements pipetransform {   transform(value) {     return (new array(value)).fill(1);   } }  @component({   (...)   template: `     <div *ngfor="let of num | fill"></div>   `,   pipes: [ fillpipe ] }) export class somecomponent {   arr:array;   num:number = 20; }
