Javascript Angular 4如何将innerHtml与*ngFor一起使用?
我有以下来自api的回复Javascript Angular 4如何将innerHtml与*ngFor一起使用?,javascript,angular,angular5,ngfor,Javascript,Angular,Angular5,Ngfor,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=\"fsdfsdfdsfs

html模板:
<div class="map" *ngFor="let map of cinema">
<div [innerHTML]="map.cinema_loc"></div>
</div>
但是不管用。如果我是console.log this.cinema.cinema\u loc。未定义。由于安全原因,Angular正在剥离它,因此您必须对其进行清理: 在模板中使用此选项:
<div class="map" *ngFor="let map of cinema">
<div [innerHTML]="safeCinema(map.cinema_loc)"></div>
</div>
在组件中使用此选项:
import { Component } from '@angular/core';
import { DomSanitizer } from '@angular/platform-browser';
@Component({
selector: 'my-app',
templateUrl: './app.component.html',
styleUrls: ['./app.component.css']
})
export class AppComponent {
name = 'Angular';
constructor(private sanitizer: DomSanitizer) {}
cinema = [
{
"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
}
];
safeCinema(cinemaLoc) {
return this.sanitizer.bypassSecurityTrustHtml(cinemaLoc);
}
}
从'@angular/core'导入{Component};
从“@angular/platform browser”导入{domsanizer};
@组成部分({
选择器:“我的应用程序”,
templateUrl:“./app.component.html”,
样式URL:['./app.component.css']
})
导出类AppComponent{
名称='角度';
构造函数(私有sanitizer:DomSanitizer){}
电影院=[
{
“电影名称”:“dfdsfsd,艾哈迈达巴德”,
“电影院”:“HIWB”,
“电影院”——“F&BCombo.jpg”,
“电影院地址”:“fsdfsdfr,免下车道路,380052,”,
“电影院”:“,
“电影院暴徒”:0
}
];
安全电影院(cinemaLoc){
返回此.sanitizer.bypassSecurityTrustHtml(cinemaLoc);
}
}
这是你的参考资料。我想这会有用的。
第一个解决方案是:
<ng-container *ngFor="let testString of testStrings">
<label [innerHtml]="testString"></label>
</ng-container>
由于某种原因,
map
变量在第一次传递时似乎未定义。尝试对前面的答案进行此修改:
只需执行以下检查-
DomSanitizer
。您可以通过@injectionDomSanitizer
并调用方法bypassSecurityTrustHtml
来实现这一点iframe
src
是正确的注意:在演示链接中,我将其用作iframe src。在控制台中,它的可能副本不起作用。正在获取电影院位置未定义。您是否尝试使用空运算符(?),例如:
[innerHTML]=“map?.cinema\u loc”
是。我也试过了,但不起作用。这是重复链接中的答案:@aloisdg,很抱歉。没有时间检查可能的重复项。:)我确实看到了连接到dev服务器…
标记在那里。不确定它为什么没有加载,您是否尝试过直接在div中加载它来检查iframe源是否实际工作?这是重复链接中的答案:
<div class="map" *ngFor="let map of cinema">
<div [innerHTML]="safeCinema(map.cinema_loc)"></div>
</div>
import { Component } from '@angular/core';
import { DomSanitizer } from '@angular/platform-browser';

})
