Angular 4如何使用带有*ngFor的innerHtml？

Question

我有以下来自api的回复

[  
   {  
      "Cinema_strName":"dfdsfsd, Ahmedabad",
      "Cinema_strID":"HIWB",
      "Cinema_strBannerImg":"F&BCombo.jpg",
      "cinema_addr":"fsdfsdfr,Drive-in Road, 380052, ",
      "cinema_loc":"<iframe src=\"fsdfsdfdsfsfdsfdsffsf4!2i768!4f13.1!3m3!1m2!1s0x0%3A0x6a9f5938cfed5cd2!2sCarnival+Cinemas!5e0!3m2!1sen!2sin!4v1467809324170\" width=\"600\" height=\"450\" frameborder=\"0\" style=\"border:0\" allowfullscreen></iframe>",
      "cinema_mob":0
   }
]

我想从api获取iframe并附加到div map

为此,我在TS文件中写道

  this.common.createAPIService('api/cinemas/List?CityName='+city, '').subscribe((result: any) => {
  if(result.length){
    this.cinema = result;
    console.log(this.cinema);
  }else{
      alert('Cinema not found');
  }
})

html模板:

<div class="map" *ngFor="let map of cinema">
     <div [innerHTML]="map.cinema_loc"></div>
 </div>

但是HTML并没有出现,但如果我正常绑定,就像下面那样

<div class="map" *ngFor="let map of cinema">
     <div>{{map?.cinema_loc}}</div>
  </div>

iframe以文本格式显示.

我如何附加为HTML？

请帮忙.

根据我在下面尝试过的解决方案

 this.common.createAPIService('api/cinemas/List?CityName='+city, '').subscribe((result: any) => {
  if(result.length){
    this.cinema = result;
    this.cinema = this.sanitizer.bypassSecurityTrustHtml(this.cinema);

    console.log(this.cinema);
  }else{
      alert('Cinema not found');
  }

但是不起作用.如果我console.log this.cinema.cinema_loc.未定义.

Answer 1

我认为这会奏效.第一个解决方案是

<ng-container *ngFor="let testString of testStrings">
<label [innerHtml]="testString"></label>
</ng-container>

和第二个解决方案是:

this.testString = this.sanitizer.bypassSecurityTrustHtml(this.testString);
