我对
javascript客户端开发的概念相当新.我遇到了一个问题,虽然我可能只是不明白如何用框架的混搭来完成某些事情.
我知道我想使用Knockout来为它提供丰富的客户端好东西.我也想使用Sammy.js来允许路由并将数据传递到淘汰视图(我来自MVC背景,我用数据填充模型,然后返回视图(模型),MVC绑定它对我很好) .
所以现在我正在尝试做类似的客户端…
这是我的Index.html：

</head>
<body>
<div id="main">
<h1>HELLO WORLD!</h1>
<!--Sammy should update the content of this div dynamically,creating a SPA (single page application)-->
</div>
</body>
</html>
这是我的Sammy配置.
(function ($) {
alert('Building Routes');
var app = $.sammy('#main',function () {
this.use('Tmpl','html');
this.get('#/',function (context) {
alert('Rendering Partial for Login page');
context.app.swap('Loading...');
this.render("/views/Login.html");
});
});
$(function () {
app.run('#/');
});
})(jQuery);
这是我的Login.html
<!--Model File Goes Here -->
<script type="text/javascript" charset="utf-8" src="../models/Login.js"></script>
<fieldset title="Please Login to Begin :">
<div data-role="content" style="padding: 15px">
<div data-role="fieldcontain">
<fieldset data-role="controlgroup" data-mini="true">
<label for="txtUsername">
Username
</label>
<input id="txtUsername" data-bind="value: username" placeholder="Stevie" value="" type="text" />
</fieldset>
</div>
<div data-role="fieldcontain">
<fieldset data-role="controlgroup" data-mini="true">
<label for="txtPassword">
Password
</label>
<input id="txtPassword" data-bind="value: password" placeholder="yep!" value="" type="password" />
</fieldset>
</div>
<a id="btnLogin" data-role="button" data-transition="fade" href="#page1" >
Login
</a>
</div>
<div id="errorText">
<h1></h1>
</div>
<p id="deviceProperties">Loading device properties...</p>
</fieldset>
<script type="text/javascript">
$(document).ready(function () {
ko.applyBindings(new LoginDataModel(0,"Stevie","theTV",true));
});
</script>
我还需要一些方法将数据从sammy get handler传递到knockout页面.有办法做到这一点,还是我尝试不可能？
更新1：
我真的很想能够做到这样的事情：
var app = $.sammy('#main',function () {
this.use('Tmpl','html');
this.get('#/',function (context) {
alert('Rendering Partial for Login page');
context.app.swap('Loading...');
var data = getLoginData();
this.render("/views/Login.html",data);
});
Sammy使用其他模板框架做了同样的事情,但是,我没有看到如何将Knockout视图中的$data绑定到从Sammy传递的数据.
