trimpath javascript的学习

TrimPath是javascript模板引擎。 

这几天有一个项目涉及到trimpath这个框架,所以就花了一点时间研究了一下,这个框架和别的javascript框架不太一样的地方就是模板的概念,就是页面中如果引入这个框架的话,就可以像jsp或着Asp那样直接在页面中混合写javascript和的代码,不用其它框架一样在javascript里首先取得页面控件的值,然后修改,然后再在javascript代码里赋值,这些是我的主要印像。 

下面先贴出来一个demo,从这个看容易入手,用这个demo前当然先要先加入像用其它框架一样加入这个框架的代码 
框架的官网主页:

从上面下一个名字叫template.js的框架文件,这个文件可以从官网上释放的最新的包中找到。例如根据我现在下的版本可以在这里找到

下面贴出demo的源码 

<html>    <head>      <script language="javascript" src="template.js"></script>    </head><body>  <div id="outputDiv">  </div>  <script language="javascript">    var data = {        products : [ { name: "mac", desc: "computer",                            price: 1000, quantity: 100, alert:null },                     { name: "ipod", desc: "music player",                       price:  200, quantity: 200, alert:"on sale now!" },                     { name: "cinema display", desc: "screen",                             price:  800, quantity: 300, alert:"best deal!" } ],        customer : { first: "John", last: "Public", level: "gold" }    };  </script><textarea id="cart_jst" style="display:none;">    Hello ${customer.first} ${customer.last}.<br/>    Your shopping cart has ${products.length} item(s):    <table>     <tr><td>Name</td><td>Description</td>         <td>Price</td><td>Quantity & Alert</td></tr>     {for p in products}         <tr><td>${p.name|capitalize}</td><td>${p.desc}</td>             <td>$${p.price}</td><td>${p.quantity} : ${p.alert|default:""|capitalize}</td>             </tr>     {forelse}         <tr><td colspan="4">No products in your cart.</tr>     {/for}    </table>    {if customer.level == "gold"}      We love you!  Please check out our Gold Customer specials!    {else}      Become a Gold Customer by buying more stuff here.    {/if}  </textarea>  <script language="javascript">    // The one line processing call...    var result = TrimPath.processDOMTemplate("cart_jst", data);    // Voila!  That‘s it -- the result variable now holds    // the output of our first rendered JST.    // Alternatively, you may also explicitly parse the template...    var myTemplateObj = TrimPath.parseDOMTemplate("cart_jst");    // Now, calls to myTemplateObj.process() won‘t have parsing costs...    var result  = myTemplateObj.process(data);    // Setting an innerHTML with the result is a common last step...    document.getElementById("outputDiv").innerHTML = result;    // You might also do a document.write() or something similar...  </script></body></html>

 

 


研究上面的demo就基本可以掌握这个框架的要点 
下面的路径是在网上搜索到的一个教程,说的挺详细的,这个教程也是从这个demo开始的,也有对个demo的详细分析,建议看看这个教程
