Firebase-身份验证时动态更改记住属性

问题描述

我在html中有一个复选框输入，用户可以在关闭浏览器后检查他/她是否希望保持登录该应用程序.我想在记住:默认"和记住:"sessionOnly"之间进行切换，具体取决于用户是否选中了该框.

I have a checkbox input in my html which the user can check if he/she wishes to stay logged into the app after the browser has been closed. I would like to change between remember: "default", and remember: "sessionOnly" depending on whether the user checks the box or not.

这是我的功能，用于检查html中的框是否已选中:

This is my function to check whether the box in the html is checked or not:

function checkLoginTerm() {
    var result;
    if(document.getElementById('#loginkeeping').checked) {
        result = "sessionOnly";
    } else {
        result =  "default";
    }
    return result;
}

然后，我在登录功能中调用该功能，以在用户进行如下身份验证后执行该功能:

Then I call the function in my login function to be executed after the user authenticates like this:

function loginUser(username, password) {
    if (checkVariable(username)) {var username = document.getElementById("loginUsername").value;}
    if (checkVariable(password)) {var password = document.getElementById("loginPassword").value;}
    firebaseRef.authWithPassword({
        email    : username,
        password : password
    }, function(error, authData) {
        if (error) {
            alert("Login Failed! "+ error, error);
        } else {
            console.log("Authenticated successfully with payload:", authData);
        }

    }, {
        remember: checkLoginTerm()
    });
}

如果我这样做，登录过程将永远无法完成.但是，如果我在记住"之后直接放置适当的字符串:(例如，记住:"sessionOnly")，它将按照其提示进行操作.

If I do this, the login process will never complete. But if I put the appropriate string directly after remember: (for example remember: "sessionOnly"), it will do what its told.

推荐答案

正如罗布·迪马科(Rob DiMarco)在我的问题下方的评论中指出的那样，有两个小问题-

As pointed out by Rob DiMarco in the comments below my question, there were two minor issues -

1. 该元素的ID为登录保留，而不是#loginkeeping
2. 我在checkLoginTerm()函数中的条件语句中犯了逻辑错误
