javascript - Handlebars 代码有什么问题？

Question

嘿，所以我正在尝试从下划线切换到 Handlebars ，但模型没有渲染任何内容，但模板正在正确更改。此外，当通过单击编辑按钮显示 editTemplate 时，#{firstName} 和其他显示为未定义。

在我的布局 jade 文件中，我包含了所有合适的文件，jquery、underscore、backbone 和 handlebar。

这是我的 main.js 文件

(function () {
    window.App = {
        Models: {},
        Collections: {},
        Views: {},
       // Templates: {},
        Router: {}

    };

    // MODEL
    App.Models.User = Backbone.Model.extend({
        defaults: {
            firstName: 'first',
            lastName: 'last',
            email: 'Email',
            phone: '222',
            birthday: 'date'
        },

        validate: function (attrs) {
            if (!attrs.firstName) {
                return 'You must enter a real first name.';
            }
            if (!attrs.lastName) {
                return 'You must enter a real last name.';
            }
            if (attrs.email.length < 5) {
                return 'You must enter a real email.';
            }
            if (attrs.phone.length < 10 && attrs.phone === int) {
                return 'You must enter a real phone number, if you did please remove the dash and spaces.';
            }
            if (attrs.city.length < 2) {
                return 'You must enter a real city.';
            }
        },

        initialize: function() {
             this.on('invalid', function (model, invalid) {
                console.log(invalid);
            });
        }

    });



    //VIEW
    App.Views.User = Backbone.View.extend({
        model: App.Models.User,
        el: 'user',
        //tagName: 'div',
        //id: 'user',
        //className: 'userProfile',


        initialize: function (){

        },

        render: function() {
            var template = Handlebars.compile($("#userTemplate").html());
            var editTemplate = Handlebars.compile($("#userEditTemplate").html());

            this.$el.html(this.template(this.model.toJSON()));
            return this;
        },

        events: {
            'click button.edit': 'editProfile',
        //  'click button.save': 'saveEdits',
            'click button.cancel': 'cancelEdits'
        },

        editProfile: function () {
            this.$el.html(this.editTemplate(this.model.toJSON()));

        }, 


        cancelEdits: function() {
            this.render();
        }

    });
    //start history service
    Backbone.history.start();

    var user = new App.Views.User({model: new App.Models.User()});
    user.render();
})();

这是我的 Jade 文件

extends layout
block content   
    div.centerContent
        script(type="text/javascript", src="/js/main.js")

        h4 User goes here with equal before it no space
            div#user
                p #{firstName} #{lastName}
                p #{email}
                p #{phone}
                p #{birthday}
                button.edit Edit



        script(id="userTemplate", type ="text/template")
                p #{firstName} #{lastName}
                p #{email}
                p #{phone}
                p #{birthday}
                button.edit Edit

        script(id="userEditTemplate", type ="text/template")
            div
                form(action="#")
                    input(type="text", class="firstName", value=#{firstName}) input(type="text", class="lastName", value=#{lastName})
                    input(type="email", class="email", value=#{email})
                    input(type="number", class="phone", value=#{phone})
                    input(type="date", class="birthday", value=#{birthday})
                button.save Save
                button.cancel Cancel

Answer 1

如果有人想看答案，基本就是这样调用的错误

#{firstName}

而不是正确的用法是:

{{firstName}}
