使用示例：

<?php    require_once(‘./atmjs.php‘);    $atmjs = new atmjs;    $atmjs->import(‘user/account:1.0.0/login‘);?><!doctype html><html><head>    <meta charset="UTF-8">    <title>Document</title>    <?php        $atmjs->loadCss();    ?></head><body><!--some html code-->

some code<?php$scripts= <<<EOTfunction (loginExport) {    //some code}EOT;    $atmjs->setJs($scripts);    $atmjs->loadJs();?></body></html>

3.生成的页面源代码：

<!doctype html><html><head>    <meta charset="UTF-8">    <title>Document</title>    <link type="text/css" rel="stylesheet" href="http://cn-style.gcimg.net/static/core/reset/1.0.0/reset_e5b6e95.css" />    <link type="text/css" rel="stylesheet" href="http://cn-style.gcimg.net/static/user/account/1.0.0/account_2e2d290.css" />    <link type="text/css" rel="stylesheet" href="http://cn-style.gcimg.net/static/user/account/1.0.0/css/login_9fa75f4.css" /></head><body><!--some html code-->

some code<script id="atmjsnode" data-base="http://cn-style.gcimg.net/static" type="text/javascript" src="http://cn-style.gcimg.net/static/lib/loader/1.0.0/loader_aa23401.js"></script><script type="text/javascript">atmjs.setMap({"_alias":{},"alias":{"user/account:1.0.0/other/ajax":"/user/account/1.0.0/other/ajax_49ac7f5.js"},"pkg":{},"cssDeps":{}});</script><script type="text/javascript" src="http://cn-style.gcimg.net/static/user/account/1.0.0/account_8c2acc1.js"></script><script type="text/javascript" src="http://cn-style.gcimg.net/static/user/account/1.0.0/exports/login_1074d04.js"></script><script type="text/javascript">atmjs.use(‘user/account:1.0.0/login‘ ,function (loginExport) {        //some code    })</script></body></html>
