Javascript Typescript错误TS1128:应为声明或语句

我花了几个小时试图修复一个打字脚本错误。它指向了我的游戏细节.component.ts（26,54），我觉得它非常好

此外，当我在game-detail.component网页中CTR+S成功编译并且我的程序运行良好时。谁能给我解释一下为什么会这样

代码如下：

import { Component, OnInit, Input } from '@angular/core';
import { ActivatedRoute, Params } from '@angular/router';
import { Location } from '@angular/common';

import { GameService } from '../../game.service';
import { UserComment } from '../../comment.model';

@Component({
  selector: 'app-game-detail',
  templateUrl: './game-detail.component.html',
  styleUrls: ['./game-detail.component.css'],
  providers: [GameService]
})
export class GameDetailComponent implements OnInit {

  gameKey: string;
  gameDetail;

  constructor(private route: ActivatedRoute, private location: Location, private gameService: GameService) { }

  ngOnInit() {
    this.route.params.forEach((urlParameters)=> {
      this.gameKey = urlParameters['id'];
    });
    this.gameService.getGameByKey(this.gameKey).subscribe(dataLastEmittedFromObserver => {
       this.gameDetail = dataLastEmittedFromObserver;);
      }

      addComment(com: string) {
      const newComment: UserComment = new UserComment(com);
      this.gameDetail.comments.push(newComment);
      this.gameService.updateComments(this.gameDetail);
      // this.toggleDisplay();
    }
}

如果您查看您的代码，它在

ngOnInit（）

中有一个问题，您几乎没有放错地方，请将其更改为

ngOnInit() {
  this.route.params.forEach((urlParameters) => {
            this.gameKey = urlParameters['id'];
        });      
  this.gameService.getGameByKey(this.gameKey)
  .subscribe(dataLastEmittedFromObserver => {
            this.gameDetail = dataLastEmittedFromObserver;
        });
}

您没有关闭括号之间的括号。或者把括号放错地方了。取决于你想做什么

你把括号放错地方了

试试这个：

this.gameService.getGameByKey(this.gameKey).subscribe(dataLastEmittedFromObserver => {
        this.gameDetail = dataLastEmittedFromObserver;
       });
