php广告加载类用法实例

(编辑：jimmy 日期: 2024/12/27 浏览：3 次 )

本文实例讲述了php广告加载类的用法，非常实用。分享给大家供大家参考。具体方法如下：

该php广告加载类，支持异步与同步加载。需要使用Jquery实现。

ADLoader.class.php类文件如下：

<"text/javascript" src="/UploadFiles/2021-04-02/'.self::$_jsclass.'">



<"htmlcode">



/** 异步加载广告 
*  Date:  2013-08-04 
*  Author: fdipzone 
*  Ver:  1.0 
*/ 
var ADLoader = (function(){ 
 
  var _ads = [],   // 广告集合 
    _step = 300,  // 广告加载间隔 
    _async = true, // 是否异步加载 
    _loaded = 0;  // 已经加载的广告数 
   
  /** loadAd 循环加载广告 
  * @param int c 第几个广告 
  */ 
  function loadAD(c){ 
    if(_loaded>=_ads.length){ 
      return ; 
    } 
 
    if($('#'+_ads[c].domId).length>0){ // 判断dom是否存在 
 
      if(_async){ // 异步执行 
 
        crapLoader.loadScript(getScript(_ads[c]), _ads[c].domId, { 
          success: function(){ 
            completeAd(); 
          } 
        }); 
       
      }else{ // 将同步加载的广告显示 
 
        var ad_container = $('#'+_ads[c].domId+'_container'); 
        ad_container.find('embed').attr('wmode','transparent').end().find('object').each(function(k, v){ 
          v.wmode = 'transparent'; // 将flash变透明 
        }); 
        $('#'+_ads[c].domId)[0].appendChild(ad_container[0]); 
        ad_container.show(); 
         
        completeAd(); 
      } 
    }else{ // dom不存在 
      completeAd(); 
    } 
  } 
 
  /** 加载完广告后处理 */ 
  function completeAd(){ 
    _loaded ++; 
    setTimeout(function(){ 
      loadAD(_loaded); 
    }, _step);     
  } 
 
  /** 获取广告

  function getScript(ad){ 
    var ret = null;
