Angular2 Learning Note (4)：How to control div style through Angular2

1. Assign backgroud image
Use [style.xxx] directly
<div class="Layout" [style.background-image]="backgroundImg">
</div>

Meet error message: something like trust issue

Add this into app.component.ts
this.backgroundImg = this.sanitizer.bypassSecurityTrustStyle('url(' + this.IndoorLayoutPath + ')');
