Can somebody PLEASE tell me what I'm doing wrong here :
I'm sorry, I feel like I'm losing my mind for 30 minutes.
getChartData() {
this.http
.get('http://localhost:3001/transactions/' + sessionStorage.getItem('id'))
.toPromise()
.then((data: any) => {
this.data = data;
});
}
<button (click)="getChartData()">click</button>
Error :
TypeError: undefined is not an object (evaluating 'this.http.get')
You have to return something from your function. With your current code example, If you hover your mouse over the function name, you'll see it says void
.
Also, I recommend using observables
rather than promises
, Angular uses heavily
getChartData() {
// return the HTTP response
return this.http.get(
'http://localhost:3001/transactions/'
+ sessionStorage.getItem('id'))
}
Then simply, subscribe to it to get the response back
someFunction() {
this.service.getChartData().subscribe((response) => console.log(response))
}
