本文实例讲述了JavaScript模板引擎用法。分享给大家供大家参考。具体如下：
这里介绍的这个模板引擎写得短小精悍，非常值得一看
tmpl.js文件如下：
// Simple JavaScript Templating // John Resig - http://ejohn.org/ - MIT Licensed (function() { var cache = {}; this.tmpl = function tmpl(str, data) { // Figure out if we're getting a template, or if we need to // load the template - and be sure to cache the result. var fn = !/W/.test(str) ? cache[str] = cache[str] || tmpl(document.getElementById(str).innerHTML) : // Generate a reusable function that will serve as a template // generator (and which will be cached). new Function( "obj", "var p=[],print=function(){p.push.apply(p,arguments);};" + // Introduce the data as local variables using with(){} "with(obj){p.push('" + // Convert the template into pure JavaScript str .replace(/[rtn]/g, " ") .split("<%").join("t") .replace(/((^|%>)[^t]*)'/g, "$1r") .replace(/t=(.*"',$1,'") .split("t") .join("');") .split("%>") .join("p.push('") .split("r") .join("'") + "');}return p.join('');" ); // Function ends // Provide some basic currying to the user return data ? fn(data) : fn; }; })();
index.html文件如下：
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>JavaScript tmpl Use Demo</title> <script type="text/javascript" src="js/jquery.min.js"></script> <script src="./tmpl.js" type="text/javascript"></script> <> <script type="text/html" id="user_tmpl"> <% for ( var i = 0; i < users.length; i++ ) { %> <li><a href="<%=users[i].url%>"><%=users[i].name%></a></li> <% } %> </script> <script type="text/javascript"> // 用来填充模板的数据 var users = [ { url: "http://baidu.com", name: "jxq"}, { url: "http://google.com", name: "william"} ]; $(function() { // 调用模板引擎函数将数据填充到模板获得最终内容 $("#myUl").html(tmpl("user_tmpl", users)); }); </script> </head> <body> <div> <ul id="myUl"> </ul> </div> </body> </html>
希望本文所述对大家的javascript程序设计有所帮助。
