嘿,我对 Handlebars.js 完全陌生,对 JavaScript 本身也几乎陌生。所以我尝试通过以下 tut:http ://coenraets.org/blog/phonegap-tutorial/

我完成了第 5 部分并想在浏览器中测试应用程序。但是页面是空白的。浏览器会自己识别handlebars.js并自动渲染handlebars模板吗?或者为什么我会收到一个空白页?

我希望这些问题不是基本的,但是我不知道如何进行或我的错误在哪里。索引.html:

<html>
<body>
    <script id="home-tpl" type="text/x-handlebars-template">
        <div class='header'><h1>Home</h1></div>
        <div class='search-bar'><input class='search-key' type="text"/></div>
        <ul class='employee-list'></ul>
    </script>



    <script id="employee-li-tpl" type="text/x-handlebars-template">
        {{#.}}
        <li><a href="#employees/{{this.id}}">{{this.firstName}} {{this.lastName}}<br/>{{this.title}}</a></li>
        {{/.}}
    </script>


    <script src="lib/jquery-1.8.2.min.js"></script>
    <script src="js/storage/memory-store.js"></script>
    <script src="js/main.js"></script>
    <script src="lib/handlebars.js"></script>

</body>

主.js:

var app = {

findByName: function() {
    var self = this;
    this.store.findByName($('.search-key').val(), function(employees) {
        $('.employee-list').html(self.employeeLiTpl(employees));
    });
},

initialize: function() {
    var self = this;
    this.store = new MemoryStore(function() {
        self.renderHomeView();
    });
    this.homeTpl = Handlebars.compile($("#home-tpl").html());
    this.employeeLiTpl = Handlebars.compile($("#employee-li-tpl").html());
},

renderHomeView: function() {
    $('body').html(this.homeTpl());
    $('.search-key').on('keyup', $.proxy(this.findByName, this));
},

showAlert: function (message, title) {
    if (navigator.notification) {
        navigator.notification.alert(message, null, title, 'OK');
    } else {
        alert(title ? (title + ": " + message) : message);
    }
},

};

app.initialize();

我在 main.js 中得到以下错误:ln。15: 未捕获的 ReferenceError: Handlebars 未定义 ln 20。:Uncaught TypeError: Object # has no method 'homeTpl'

亲切的问候,斯纳夫

将您的脚本标签移到handlebars.js上方。main.js

我做了上述改变......这似乎很合乎逻辑。但是,上述解决方案不起作用。

我在下面添加了

this.homeTpl = Handlebars.compile($("#home-tpl").html());
this.employeeLiTpl = Handlebars.compile($("#employee-li-tpl").html());

在 renderHomeView 函数中......对我来说很好...... :)

renderHomeView: function()  {       
    this.homeTpl = Handlebars.compile($("#home-tpl").html());
    this.employeeLiTpl = Handlebars.compile($("#employee-li-tpl").html());
    $('body').html  ( this.homeTpl());
    $('.search-key').on('keyup', $.proxy(this.findByName, this));   
}
