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=(.*?)%>/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文件如下:

希望本文所述对大家的javascript程序设计有所帮助。
