Earlier we could add event listener to endpoints using -
this.instance = newInstance({
container: this.wrapper.nativeElement,
});
_addEndpoints(
id: string,
sourceAnchors: Array<AnchorSpec>,
targetAnchors: Array<AnchorSpec>
) {
const endpointDOMEl = document.getElementById(`endpoint_${id}`);
for (let i = 0; i < sourceAnchors.length; i++) {
const sourceUUID = id + sourceAnchors[i];
const endpoint = this.instance.addEndpoint(
endpointDOMEl,
this.sourceEndpoint,
{
anchor: sourceAnchors[i],
uuid: sourceUUID,
}
);
this.addListenersForEndpoint(endpoint, endpointDOMEl, null);
}
}
addListenersForEndpoint() {
endpoint.canvas.removeEventListener('mouseover', addHoverListener);
endpoint.canvas.removeEventListener('mouseout', removeHoverListener);
endpoint.canvas.addEventListener('mouseover', addHoverListener.bind(null, endpoint, domCircleEl, labelId));
endpoint.canvas.addEventListener('mouseout', removeHoverListener.bind(null, endpoint, domCircleEl, labelId));
}
But, in 5.x i can't see the canvas property anymore. What alternative can i use to achieve the same?
You should bind to the endpoint mouseover and mouseout events:
https://docs.jsplumbtoolkit.com/community/lib/events
instance.bind(EVENT_ENDPOINT_MOUSEOVER, (e:Endpoint) => {
..
})
