JavaScript模板引擎用法執行個體，javascript模板執行個體
本文執行個體講述了JavaScript模板引擎用法。分享給大家供大家參考。具體如下：
這裡介紹的這個模板引擎寫得短小精悍，非常值得一看
tmpl.js檔案如下：
// 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(/[\r\t\n]/g, " ") .split("<%").join("\t") .replace(/((^|%>)[^\t]*)'/g, "$1\r") .replace(/\t=(.*?)%>/g, "',$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檔案如下：
<!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> <!-- 下面是模板user_tmpl --> <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"> // 用來填充模板的資料 var users = [ { url: "http://baidu.com", name: "jxq"}, { url: "http://google.com", name: "william"} ]; $(function() { // 調用模板引擎函數將資料填充到模板獲得最終內容 $("#myUl").html(tmpl("user_tmpl", users)); }); </script> </head> <body> <div> <ul id="myUl"> </ul> </div> </body></html>
