下面的是我的测试代码。首先是主函数的。

<!DOCTYPE html>
<html>
<head>
<title>
</title>
</head>
<body>
<script type="text/javascript" src="base.js"></script>
<script type="text/javascript" src="deps.js"></script>
<script type="text/javascript">
alfred.reset("$");

$.require("alfred.dom");

$.ready(function(){
    var a = $.dom("<div id='test' style='width:200px;height:200px;background:red;'> adf</div>");
    $.dom("body").prepend(a);
})
</script>
</body>
</html>

下面是选择器的

<!DOCTYPE html>
<html>
<head>
<title>
</title>
</head>
<body>
<div>
<ul>
<li><a href="#"></a></li>
<li><a href="#"></a></li>
<li><a href="#"></a></li>
<li><a href="#"></a></li>
<li><a href="#"></a></li>
<li><a href="#"></a></li>
<li><a href="#"></a></li>
</ul>
<a>
<div>first</div>
</a>
</div>
<script type="text/javascript" src="base.js"></script>
<script type="text/javascript" src="deps.js"></script>
<script type="text/javascript">
alfred.reset("$");
$.require("alfred.dom");
$.ready(function(){
        var div = alfred.dom('<div id="a" class="b">adf</div>');
    alfred.dom("div a")
    .append("this is a test")
    .prepend(div)
    .append(div)
    .attr("id","name");            

});    
</script>
</body>
</html>

文件的路径要在数据库文件对应就可以进行require  或者自己手动setMethod

不喜欢我的全局变量 可以象上面那样

alfred.reset("xxxxx") 你想放什么自己放。

技术狠烂。求师傅指点。。。。。。。
