这是我的read.html,其中填写并提交了表单。
<form class="mt-3 text-center" (ngSubmit)="onSubmit()">
<div class="text-center">
<input type="text" name="barcode" class="form-control text-center mt-2" [(ngModel)]="barcode" placeholder="Barcode">
</div>
</form>
这是我的read.ts,在提交表单之后,在其中调用服务并返回信息。
constructor(private ticketlineservice: TicketlineService,
private activatedRoute: ActivatedRoute) {
this.activatedRoute.queryParams.subscribe(params => {
this.codEspec = params['CodEspec'];
this.DiaHoraEspecs = params['DiaHoraEspecs'];
});
}
ngOnInit() {
}
onSubmit(){
console.log(this.barcode,this.codEspec,this.DiaHoraEspecs );
this.ticketlineservice.CheckTicket(this.barcode, this.codEspec, this.DiaHoraEspecs).subscribe(reads => {
this.reads = reads[0].Tickets;
console.log(reads);
});
}
我正在调用的服务的功能。其他两个参数(codEspec和DiaHoraEspecs)来自先前的网址。
CheckTicket(barcode, codEspec, diaHoraEspec):Observable<Ticket[]>{
//get todos os eventos
return this.http.get<Ticket[]>(`${this.url_node_tickets}${this.barcode}${this.codEspec}${this.diaHoraEspec}`, httpOptions);
}
问题::控制台日志中的所有值均显示且正确,但在url中,条形码不变。
答案 0 :(得分:1)
CheckTicket(barcode, codEspec, diaHoraEspec):Observable<Ticket[]>{
//get todos os eventos
return this.http.get<Ticket[]>(`${this.url_node_tickets}${this.barcode}${this.codEspec}${this.diaHoraEspec}`, httpOptions);
}
${this.barcode}${this.codEspec}${this.diaHoraEspec}
我认为您需要删除其中的this
(类引用)并使用函数的参数吗?
${barcode}${codEspec}${diaHoraEspec}
