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：
rush:js;">
// 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;
};
})();
