角仅在chrome上有效，但在Firefox边缘或IE11上有效

Question

在我的angular 8.0项目开发模式下，使用angular CLI。

仅适用于chrome，一切正常，但不适用于firefox / edge / IE11。

[当我在firefox / Edge中打开项目时，我在登录页面中存储了，我输入我的帐户/密码，然后单击login，什么都不会发生，F12中没有错误或消息。

当我在IE11中打开项目时，只有白页，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，但它也不起作用。

  },(error)=>{
    this.checkAuth=true;
    console.log(error);
  }
  );

}`

我的登录服务

`postAccountInfo（用户名，paswword）{

//AuthInfo:AuthInfo;

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

}`

您需要编辑浏览器列表文件，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，仅从最后一行删除not关键字，然后尝试。
