I have svg items that highlights their corresponding path when user click on them or hover them.
I'm using Directives to detect onEnter onLeave and Click events.
Its working fine when I hover ( I highlight ) then when I leave the element (I Play down )
Then When I click also the path is highlighted (
Actually what's happen is when I click elsewhere the Highlight stays.
What I can't do so is when I click on the rest of the screen I would like that the Highlight disappear.
Here's my directive logic
export class HighlightDirective {
constructor(private renderer:Renderer2 , private el: ElementRef) {}
clicked=false
@HostListener('mouseenter') onMouseEnter() {
this.changeOpacity(1);
}
@HostListener('mouseleave') onMouseLeave() {
if (!this.clicked) {
this.changeOpacity(0);
}
}
@HostListener('click') click() {
this.changeOpacity(1);
this.clicked = true;
}
changeOpacity(opacity: number) {
this.renderer.setStyle(this.el.nativeElement.nextSibling, 'opacity', opacity);
}
}
And here's a part of the SVG with the Highlight attribute tag
<g id="b1" transform="translate(-885 -562)">
<g id="b1select">
<ellipse id="Ellipse_1" data-name="Ellipse 1" cx="5.3" cy="5.3" rx="5.3" ry="5.3" transform="translate(1309.17 932.12)" fill="none" stroke="#b18802" stroke-width="1"/>

</g>
<rect appHighlight (click)="openDialog($event)" id="container" width="12" height="11" transform="translate(1308.67 931.62)" fill="rgba(255,255,255,0)"/>

</g>
