Angular 2：更改了innerHTML属性和图像src路径

动态地，我从我的服务器以json格式获取HTML内容。Angular 2：更改了innerHTML属性和图像src路径

{ "title":"Home", "name":"ss_home", "content":"<div class=\"ExternalClass3dfsfsf204E51\"><table id=\"layoutsTable\" style=\"width&#58;100%;\"><tbody><tr style=\"vertical-align&#58;top;\"><td style=\"width&#58;100%;\"><div class=\"ms-rte-layoutszone-outer\" style=\"width&#58;100%;\"><div class=\"ms-rte-layoutszone-inner\"><div class=\"ms-rtestate-read ms-rte-embedcode ms-rtestate-notify ms-rte-embedil s4-wpActive\" unselectable=\"on\"><table border=\"1\" width=\"850\" unselectable=\"on\"><tbody unselectable=\"on\"><tr unselectable=\"on\"><td unselectable=\"on\"> \r\n    <strong unselectable=\"on\">Quality Policy&#58;</strong><br unselectable=\"on\"><strong unselectable=\"on\" style=\"line-height&#58;20px;\"><em unselectable=\"on\">“Some content”.</em> </strong></td></tr><tr unselectable=\"on\"><td unselectable=\"on\">\r\n    <strong unselectable=\"on\">Deriving Project Quality Objectives-Approach</strong><span unselectable=\"on\" style=\"line-height&#58;19px;\"> </span>\r\n    <img width=\"850\" height=\"414\" src=\"/org/Data/Home-page.png\" title=\"Home page\" class=\"alignnone size-large wp-image-34364857\" unselectable=\"on\" data-themekey=\"#\" alt=\"\" /> &#160; </td></tr></tbody></table> \r\n <span unselectable=\"on\" style=\"line-height&#58;30px;\">\r\n  <br unselectable=\"on\">\r\n  <strong unselectable=\"on\">Organization Chart</strong></span><img width=\"650\" height=\"350\" src=\"/org/Data/Org_chart.jpg\" title=\"Org chart\" class=\"alignnone size-large wp-image-34138132\" unselectable=\"on\" data-themekey=\"#\" alt=\"\" /></div><p><a class=\"link_nav\" data-action=\"project_initiation\" href=\"#\" title=\"Project Initiation\" unselectable=\"on\">Project Initiation</a> \r\n <br> </p></div></div></td></tr></tbody></table><span id=\"layoutsData\" style=\"display&#58;none;\">false,false,1</span></div>" }

component.ts

<div class="content" [innerHTML]="pq.content_QMS | safeHtml"></div>

sate.html.pipe.ts

transform(value) { 
return this.sanitized.bypassSecurityTrustHtml(value); }

没有其他选择，我要改变这种html内容。但是，对于我的应用我有实现两件事情，

更改图像路径
添加点击事件

最终输出应该是：

<img src="/org/Data/Org_chart.jpg" /> to <img src="http://example.com/org/Data/Org_chart.jpg"

和

<a class="link_nav" data-action="project_initiation" href="#" title="Project Initiation"> to  <a class="link_nav" (click)="project_initiation" href="#" title="Project Initiation">

我们如何使用任何管道regrex或其他逻辑来实现它？给我一些功能性的建议。

1.“改变图像路径”，你可以通过纯文本操作。 2.事件 - 你可以尝试在组件的hostelement上设置处理程序，并在那里处理它 –

@JuliaPassynkova我尝试了addEventListner this.elementRef.nativeElement.querySelector（'。link_nav'）。addEventListener（'click'，'but event不触发innerHTML内容 –

@Component({ 
    selector: 'my-app', 
    template: ` 
    <div> 
    <div class="content" [innerHTML]="value"></div> 
    </div> 
    `, 
    }) 
    export class App implements OnInit { 
    value; 

    constructor(private sanitized: DomSanitizer) { 
    } 

    @HostListener('click', ['$event.target']) 
    clicked(eventTarget: HTMLElement) { 
     console.log('clicked', eventTarget); 
    } 

    ngOnInit() { 
    this.value = 
    this.sanitized.bypassSecurityTrustHtml('<a href="#" 
     href="javascript:void(0)">hi link<a>'); 
    } 
}
