Question

我正在尝试使用typescript添加带有id的div，但它没有分配它。我只得到div

app.component.html

<div class="one" [innerHtml]="htmlToAdd">

</div>

app.component.ts

import { Component } from '@angular/core';
import { Http } from '@angular/http';
import * as shape from 'd3-shape';
import { ElementRef } from '@angular/core';
declare var $: any;

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent {
   ngOnInit() {

    this.addDiv()

  }

  addDiv(){
     this.htmlToAdd = '<div class="two" id="myId">my div</div>';
  }

}

要给它一个灵感，即使它可能不是一个最佳的解决方案。 Here is a Stackblitz

在您的组件中

trustedHtml: SafeHtml;

constructor(public s: DomSanitizer) {}

ngOnInit() {
    this.addDiv();
}

public addDiv() {
    this.trustedHtml = this.s.bypassSecurityTrustHtml("<div class='two' id='myId'>my div</div>")
}

和你的Html

<div [innerHTML]="trustedHtml"></div>

如何使用角度4中的动态Id动态创建div
