Angular 2 Hover event

If you want to perform a hover like event on any HTML element, then you can do it like this.

HTML

 <div (mouseenter) ="mouseEnter('div a') "  (mouseleave) ="mouseLeave('div A')">
        <h2>Div A</h2>
 </div> 
 <div (mouseenter) ="mouseEnter('div b')"  (mouseleave) ="mouseLeave('div B')">
        <h2>Div B</h2>
 </div>

Component

import { Component } from '@angular/core';

@Component({
    moduleId: module.id,
    selector: 'basic-detail',
    templateUrl: 'basic.component.html',
})
export class BasicComponent{

   mouseEnter(div : string){
      console.log("mouse enter : " + div);
   }

   mouseLeave(div : string){
     console.log('mouse leave :' + div);
   }
}

You should use both mouseenter and mouseleave events in order to fully implement functional hover events in angular 2.
