Waiting until method is finished-CodePudding

I have an array public trackedElements: TrackingEvent[]; in which I write data:

this.trackedElementService.trackingEventsGetTrackingEventsbyElementIdFromtimestampTotimestampElementIdGet(this.fromDate.toISOString().slice(0, 10), this.toDate.toISOString().slice(0, 10), this.trackedElement.elementId.toString()).subscribe((data: TrackingEvent[]) => {
   this.trackedElements = data;
});

I call this method the moment the component is initialized, but this.trackedElements doesn't have all the data when the next method is already called in which I want to use the data.

My goal is to figure out how to stop the next method to be called until this.trackedElements is filled completely.

CodePudding user response：

Please try calling the next method after variable has data

this.trackedElementService.trackingEventsGetTrackingEventsbyElementIdFromtimestampTotimestampElementIdGet(this.fromDate.toISOString().slice(0, 10), this.toDate.toISOString().slice(0, 10), this.trackedElement.elementId.toString()).subscribe((data: TrackingEvent[]) => {
   this.trackedElements = data;
// please call next method here like, this.nextMethod()
});
