Question

在我的Angular 8.0项目开发模式下，使用angular CLI。

它仅适用于Chrome，一切正常，但不适用于Firefox / Edge / IE11。

在Firefox / Edge中打开项目时，我停留在登录页面上，键入帐户/密码，然后单击登录，但是F12中什么都没有发生，没有错误或消息。

当我在IE11中打开项目时，只有白色页面，也没有错误或消息。

请帮助我怎么做

我发现有人说在polyfills中导入es6-slim或reflict.js，但这也不起作用。

我的package.json

    "ts-node": "~8.4.1",
    "tslint": "~5.20.0",
    "typescript": "3.5.3"
  }
}

我的登录页面组件：

completeSetup(): void {
    //console.log(data);
    this.loginService.postAccountInfo(this.username, this.password)
      .subscribe(res => { 
        this.obj = res 
        this.store.set(INIT_FLAG, true);
        this.store.set(USERNAME, this.username);
        this.store.set(AUTHTOKEN,this.obj.authToken);
        console.log("login sucess");
        this.router.navigateByUrl('main/sc/candidate');
      },
      (error) => {
         this.checkAuth = true;
         console.log(error);
      });
  }

我的登录服务：

postAccountInfo(username, paswword) {
    //AuthInfo:AuthInfo;

    return this.http.post("/um/login", {
      observe: "response",
      userName:username,
      password:paswword,
      groupId:"1234",
      orgId:"ykdemo"
    }).pipe(
      catchError(this.handleError)
    );
  }

我发现问题与下面的拦截器有关， console.log不会显示，但是在Chrome中可以正常运行，多么奇怪！

return next.handle(authReq)
.pipe( map((event: any) => {
  this.handleData(event);
  console.log("------") //console will not show
  if (event instanceof HttpResponse && event.status === 200)
  {   
      return event;
  }

}),
catchError(
  (err: HttpErrorResponse) => this.handleData(err)
  )
)

Answer 1

您需要编辑browserlist文件，并在此配置文件中允许IE11。如果使用Angular CLI项目，则会自动创建此文件。只需打开文件，文件包含如下-

> 0.5%
last 2 versions
Firefox ESR
not dead
not IE 9-11 # For IE 9-11 support, remove 'not'.

按照上述说明，只需从最后一行删除not关键字，然后尝试。

对不起，我发现发生了什么事我的错，与浏览器或角度无关我在本地存储区出错，导致这种情况发生，感谢您的帮助，可以关闭此问题。

Angular仅适用于chrome，不适用于Firefox。 Edge或IE11
