Accessing MongoDB in HTML

Question

我是Web编程的新手，我想在网站上为注册用户创建一个配置文件页面，我无法理解。基本上只是用户的名字和他选择的图片。

那是我的个人资料。Handlebars代码：

<div class="row">
    <div class="col-md-4">
        <h1><%= user.firstName + " " + user.lastName %></h1>
        <div class="thumbnail">
            <img src="<%= user.avatar %>" alt="user profile image">
            <div class="caption"><a href="mailto:<%= user.email %>"><%= user.email %></a></div>
        </div>
    </div>
</div>
    <div class="col-md-8">
        description 
    </div>

这是user.js模型：

var mongoose = require('mongoose');
var bcrypt = require('bcryptjs');
var passportLocalMongoose = require("passport-local-mongoose");
// User Schema
var UserSchema = mongoose.Schema({
    username: {
        type: String,
        index:true
    },
    password: {
        type: String
    },
    email: {
        type: String
    },
    name: {
        type: String
    },
    avatar: {
        type: String
    }
});
UserSchema.plugin(passportLocalMongoose);
var User = module.exports = mongoose.model('User', UserSchema);

发生的是profile.handlebars代码只是打印"＆lt;％=用户...."，因为它是字符串，我希望它打印现在登录的用户名称。

这些是打开个人资料时我遇到的错误。

预先感谢！

尝试使用{{user.avatar}}和{{user.email}}

＆lt;％=％>符号在JSP中用于车把您应该在变量周围使用卷曲括号{{}}。
