如果用户键为大写字母，如何自动将密码设置为小写

My goal is to set the username to lowercase if user accidentally key in uppercase letters in angular2.

我的目标是如果用户意外地在angular2中键入大写字母，则将用户名设置为小写。

For an example, i set the user name to admin , if user key in Admin. It should recognize as "admin" rather than "Admin".

例如，如果管理员中有用户密钥，我将用户名设置为admin。它应该被识别为“管理员”而不是“管理员”。

I have tried to add .toLowerCase but it is not working correctly and i am usure how should i code it..

我试图添加.toLowerCase，但它无法正常工作，我很有用，我该怎么编码呢..

This is my original code i have and it is working, Admin must key in as "admin" inside user and it will work.

这是我的原始代码，它正在工作，管理员必须在用户内部输入“admin”，它才能正常工作。

But what i am working at is. i want to make it not key sensetive. so if admin key in as "Admin" . he is able to log in as well without modifying my code.

但我正在做的是。我想让它不是关键的感觉。所以如果admin键入“Admin”。他也可以在不修改我的代码的情况下登录。

loginCallback: (params: any)=>{
        if(params.user == "admin" && params.pass == "demo")  this._router.navigate(["/App/Version/3-0-0"])
        else this._errorSvc.setErrorMsg("You have entered an invalid username or password.");
    }

As mentioned above. I tried using this, i just simply added .toLowerCase. but when i tried to log in as "admin" or "Admin" . Nothing is working. Any help will be greatly appreciated. Thanks .

正如刚才提到的。我尝试使用它，我只是添加.toLowerCase。但当我尝试以“管理员”或“管理员”身份登录时。没有什么工作。任何帮助将不胜感激。谢谢 。

loginCallback: (params: any)=>{
        if(params.user.toLowerCase == "admin" && params.pass == "demo")  this._router.navigate(["/App/Version/3-0-0"])
        else this._errorSvc.setErrorMsg("You have entered an invalid username or password.");
    }

You're missing parentheses after toLowerCase().

在toLowerCase（）之后你缺少括号。
