有沒有其他方法添加五角星/星星圖案。
使用github octicons：
npm install octicons

  <image xlink:href="node_modules/octicons/build/svg/star.svg" />

商品星星評分：

export class StarsComponent implements OnInit {
@Input()
  private  rating: number =0;

  private staricon: string;

  constructor() {
  }

  ngOnInit() {
    this.staricon = "";
    for(let i=1;i<=5;i++){
      if(i<= this.rating) this.staricon = this.staricon + "★";
      else this.staricon = this.staricon + "☆";
   
    }
}
}
