demo.php示例程序如下：

  1. <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
  2. <html>
  3. <head>
  4. <meta http-equiv="content-type" content="text/html; charset=utf-8">
  5. <title> AD Loader </title>
  6. <style type="text/css">
  7. .banner1{margin:10px; border:1px solid #CCCCCC; width:728px; height:90px;}
  8. .banner2{margin:10px; border:1px solid #CCCCCC; width:300px; height:250px;}
  9. </style>
  10. <script type="text/javascript" src="http://code.jquery.com/jquery-1.10.1.min.js"></script>
  11. </head>
  12. <body>
  13. <div class="banner1" ></div>
  14. <div class="banner2" ></div>
  15. <div class="banner2" ></div>
  16. <?php
  17. function showAD($channel='', $step='', $async=''){
  18. include('ADLoader.class.php');
  19. $ad_config = include('ADConfig.php');
  20. ADLoader::setConfig($ad_config, 'ADLoader.js');
  21. return ADLoader::load($channel, $step, $async);
  22. }
  23. echo showAD('case_openx'); // 异步加载
  24. //echo showAD('case_url'); // url方式异步加载
  25. //echo showAD('case_sync_openx', 300, false); // 同步加载
  26. ?>

adurl.php文件如下：

  1. <?php

  3. if($zoneid){
  4. ?>
  5. var zoneid = <?=$zoneid ?>;
  6. var m3_u = (location.protocol=='https:'?'https://ads.nmg.com.hk/www/delivery/ajs.php':'http://ads.nmg.com.hk/www/delivery/ajs.php');
  7. var m3_r = Math.floor(Math.random()*99999999999);
  8. if (!document.MAX_used) document.MAX_used = ',';
  9. document.write ("<scr"+"ipt type='text/javascript' src='"+m3_u);
  10. document.write ("?zoneid=" + zoneid);
