Looking to retrieve mouse coordinates in an Angular component.
This is the HTML snippet:
<div id="container" class="fullSize" style="height:100%;" (click)="onClick(ev)"></div>
And here's the corresponding function in the TypeScript file:
onClick( ev : MouseEvent ) {
console.log("x:" + ev.clientX);
}
The console shows this error:
Cannot read property 'clientX' of undefined'
How can I correctly pass the MouseEvent to my component function?
To ensure the MouseEvent object is passed to your click handler, use $event.
Simply include this:
(click)="onClick($event)"
For more information, refer to:
Current recommended approach:
<div id="wrapper" class="fullHeight" style="height:100%;" (click)=handleClickEvent($event.clientX)"></div>
handleClickEvent(clickedClientX: number) {
console.log("clicked x-coordinate: " + clickedClientX);
}
As per the latest guideline provided in this Angular documentation link, passing $event is not recommended.
