this is how it jumps in another route:
_this.router.navigate(["/examdetail"], { queryParams: { examid: _this.examId[dataIndex]}});
when jumping to the examdetail route, only constructor,ngOnInit is triggered, not triggered:
ngOnInit() {
console.log(222);
}
oninitoninityou can listen to the params event of ActiveRoute directly
constructor(private _route: ActivatedRoute,) {
this._route.params.subscribe((params: Params) => {
//params: {examid: }
}
}
you must be jumping under the same route examdetail .
