为什么我在主干中的视图没有呈现？

Question

我正在尝试从我的主干视图呈现此模板，但它不起作用？任何人都知道我在这里做错了什么谢谢！我将包含用于视图的玉文件和用于主干 js 脚本的 main.js 文件。

玉文件

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

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() {
             user.on('invalid', function (model, invalid) {
                console.log(invalid);
            });
        }

    });



    //VIEW
    App.Views.User = Backbone.View.extend({
        model: App.Models.User,
        //tagName: 'div',
        //id: 'user',
        //className: 'userProfile',
        template: _.template($("#userTemplate").html());
        editTemplate: _.template($("#userEditTemplate").html());


        initialize: function (){

        }

        render: function() {
            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({el: 'div #user'});
    user.render();
})();

我发现您没有为骨干视图分配模型。

所以你可以试试这个：

      var MyModel = Backbone.Model.extend({
        defaults: {
            name: 'first',
            lastName: 'last',
            email: 'Email',
            phone: '222',
            birthday: 'date'
        }
    });

    var MyView = Backbone.View.extend({
        el: "#user",
        model: MyModel,
        template: _.template($("#test-template").html()),
        render: function(){
            this.$el.html(this.template(this.model.toJSON()));
            return this;
        }
    });

    var myView = new MyView({model:new MyModel()});
    myView.render();

而测试模板是：

<script id="test-template" type="text/template">
   <div><%=name%></div>
</script>

HTML：

<body>
<div id="user">
</div>
</body>

您可以在 Backbone 视图声明中定义主干视图的 el 属性。并记住在启动时为视图分配模型。

玉：

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

修改模板生成方式：

<script src="https://raw.github.com/weepy/jade-browser/master/jade.js"></script>
<script src="https://raw.github.com/weepy/jade-browser/master/jade-shim.js"></script>

template: jade.compile($("#userTemplate").text());

希望这对你有帮助。
