我目前的代码是这样的,但是第一个名字就像它的显示方式一样。我想弄清楚这是什么在玉,因为这是不对的。

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 <%=birthday1%>
            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="date", class="birthday", value="<%= birthday %>")
            button.save Save
            button.cancel Cancel

这里我将包含我的main.js文件,也许我在那里做错了。

main.js

(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();
})();

就Jade而言,"<%= firstName %>"只是一个String字面值。但是,它会对HTML进行编码:

<input type="text" class="firstName" value="&lt;%= firstName %&gt;">

要保持该值不变,请在!之前添加=以跳过编码。

input(type="text", class="firstname", value!="<%= firstName %>")
<input type="text" class="firstName" value="<%= firstName %>">

默认情况下,=缓存的代码会被转义为安全性,但要输出未使用的返回值,您可以使用!=

p!= aVarContainingMoreHTML

另请注意,if you're using an older version of Jadescript元素的内容可以整体视为文字文字。

  

Jade版本0.31.0已弃用隐式文本仅支持脚本和样式。要解决此问题,您需要在脚本或样式标记之后添加.字符。

在0.31.0之前,您的视图将呈现为(删节):

<script id="userEditTemplate" type="text/template">
    div.userProfile
        form(action="#")
        # ...
</script>
