Question

此代码来自本教程：https://waaave.com/tutorial/meteor/design-a-complete-authentication-system-with-meteor/#L11

这是步骤6.1，据我所知，没有错误但由于某种原因它不起作用，当我点击它时“忘记密码”链接什么都不做。有谁知道什么是错的？

使用Javascript：

Template.main.helpers({
    showForgotPassword: function() {
        return Session.get('showForgotPassword');
    }
});

// Sign In Template
Template.signIn.events({
    'submit #signInForm': function(e, t) {
        e.preventDefault();

        var signInForm = $(e.currentTarget),
            email = trimInput(signInForm.find('.email').val().toLowerCase()),
            password = signInForm.find('.password').val();

        if (isNotEmpty(email) && isEmail(email) && isNotEmpty(password) && isValidPassword(password)) {
            Meteor.loginWithPassword(email, password, function(err) {
                if (err) {
                    Session.set('alert', 'We\'re sorry but these credentials are not valid.');
                } else {
                    Sesson.set('alert', 'Welcome back New Meteorite!');

                }
            });
        }
        return false;
    },

      'click #showForgotPassword': function(e, t) {
        Session.set('showForgotPassword', true);
        return false;
    },

});

HTML：

            {{> signOut}}
     {{#unless resetPassword}}
         {{#unless currentUser}}
             {{#unless showForgotPassword}}
             {{else}}

Answer 1

在本教程中的那一点（6.1），您还没有为forgotPassword配置任何事件处理程序。它没有用，因为代码还没有。

在下一节6.2中，作者将引导您发送一封用于启动密码恢复的电子邮件：

Template.forgotPassword.events({
    'submit #forgotPasswordForm': function(e, t) {
        e.preventDefault();

        var forgotPasswordForm = $(e.currentTarget),
            email = trimInput(forgotPasswordForm.find('#forgotPasswordEmail').val().toLowerCase());

        if (isNotEmpty(email) && isEmail(email)) {
            Accounts.forgotPassword({email: email}, function(err) {
                if (err) {
                    if (err.message === 'User not found [403]') {
                        Session.set('alert', 'This email does not exist.');
                    } else {
                        Session.set('alert', 'We\'re sorry but something went wrong.');
                    }
                } else {
                    Session.set('alert', 'Email Sent. Please check your mailbox to reset your password.');
                }
            });
        }
        return false;
    },

    'click #returnToSignIn': function(e, t) {
        Session.set('showForgotPassword', null);
        return false;
    },
});

这是我在最近的教程中看到的常见模式。

作者不是在开始时给你一个完整的应用程序并将其分解，而是采用迭代方法并逐个构建应用程序，这是你在构建应用程序时通常会做的事情。

因此它作为教程非常有效。请耐心等到最后：）

更新：忘记密码表单没有显示，因为它应该在名为main的模板中，如下面的代码所示：

<template name="main">
    {{> alert}}
    {{#unless resetPassword}}
        {{#unless currentUser}}
            {{#unless showForgotPassword}}
                {{> signIn}}
                {{> signUp}}
            {{else}}
                {{> forgotPassword}}
            {{/unless}}
        {{else}}
            {{> signOut}}
        {{/unless}}
    {{else}}
        {{> resetPassword}}
    {{/unless}}
</template>

并且以下助手使用会话参数并将其提供给unless块：

Template.main.helpers({
    showForgotPassword: function() {
        return Session.get('showForgotPassword');
    }
});

但是您的代码没有main模板，而是将代码包装在通用div中，而且您似乎也更改了代码的其他部分。

<div id="topbar">
            {{> signOut}}
     {{#unless resetPassword}}
         {{#unless currentUser}}
             {{#unless showForgotPassword}}
             {{else}}
                  {{> forgotPassword}}
             {{/unless}}
         {{else}}
          {{/unless}}
     {{else}}
         {{> resetPassword}}
     {{/unless}}
    </div>

因此，您可以使用教程中的原始代码，或者如果您确实想要更改该代码，则可以使用原始代码中的topbar div包裹main template。< / p>

这段代码不起作用（无缘无故）？
