Question

我正在尝试合并两个可观察值，比较两个值并根据结果输出宽度。我正在按照https://coryrylan.com/blog/angular-multiple-http-requests-with-rxjs#forkjoin

中的步骤进行操作

该错误实际上在此代码中

 .subscribe( (results) =>  {

我也尝试过使用此代码，但是错误仍然相同

.subscribe( ([res1, res2]) =>  {

代码如下：

 ngOnInit() {
  forkJoin([this.sidenavService.lSidenavOpenSub$, this.sidenavService.rSidnavOpenSub$])
  .subscribe( (results) =>  { 
    if (results[0] == false && results[1] == false) {
      this.width = this.widthService.width100;
      debugger;
      console.log('noneOpen');
      } else if (results[0] == true && results[1] == false) {
      this.width = this.widthService.width100 - this.leftWidth;
      debugger;
      console.log('leftOpen');
    } else if (results[0] == true && results[1] == true) {
      this.width = this.widthService.width100 - (this.rightWidth + this.leftWidth);
      debugger  
      console.log('bothOpen');
    } else if (results[0] == false && results[1] == true) {
      this.width = this.widthService.width100 - this.rightWidth;
      debugger
      console.log('rightOpen');
    }
  }
}

subscribe末尾缺少右括号

  .subscribe( (results) =>  { 
    if (results[0] == false && results[1] == false) {
      this.width = this.widthService.width100;
      debugger;
      console.log('noneOpen');
      } else if (results[0] == true && results[1] == false) {
      this.width = this.widthService.width100 - this.leftWidth;
      debugger;
      console.log('leftOpen');
    } else if (results[0] == true && results[1] == true) {
      this.width = this.widthService.width100 - (this.rightWidth + this.leftWidth);
      debugger  
      console.log('bothOpen');
    } else if (results[0] == false && results[1] == true) {
      this.width = this.widthService.width100 - this.rightWidth;
      debugger
      console.log('rightOpen');
    }
  }) // here ...................

出现错误“，”。在ForkJoin上并在ngOnInit中合并最新
