网络营销我帮您-于海龙为您网络营销指点迷经！

ecshop乱飞的版权主要是由于一下这个随机函数导致的：
onload = function()
{
    var link_arr = document.getElementsByTagName(String.fromCharCode(65));
    var link_str;
    var link_text;
    var regg, cc;
    var rmd, rmd_s, rmd_e, link_eorr = 0;
    var e = new Array(97, 98, 99,
                      100, 101, 102, 103, 104, 105, 106, 107, 108, 109,
                      110, 111, 112, 113, 114, 115, 116, 117, 118, 119,
                      120, 121, 122
                      );

try
{
    for(var i = 0; i < link_arr.length; i++)
    { 
      link_str = link_arr.href;
      if (link_str.indexOf(String.fromCharCode(e[22], 119, 119, 46, e[4], 99, e[18], e[7], e[14], 
                                             e[15], 46, 99, 111, e[12])) != -1)
      {
        if ((link_text = link_arr.innerText) == undefined)
        {
            throw "noIE";
        }
        regg = new RegExp(String.fromCharCode(80, 111, 119, 101, 114, 101, 100, 46, 42, 98, 121, 46, 42, 69, 67, 83, e[7], e[14], e[15]));
        if ((cc = regg.exec(link_text)) != null)
        {
          if (link_arr.offsetHeight == 0)
          {
            break;
          }
          link_eorr = 1;
          break;
        }
      }
      else
      {
        link_eorr = link_eorr ? 0 : link_eorr;
        continue;
      }
    }
} // IE
catch(exc)
{
    for(var i = 0; i < link_arr.length; i++)
    {
      link_str = link_arr.href;
      if (link_str.indexOf(String.fromCharCode(e[22], 119, 119, 46, e[4], 99, 115, 104, e[14], 
                                               e[15], 46, 99, 111, e[12])) != -1)
      {
        link_text = link_arr.textContent;
        regg = new RegExp(String.fromCharCode(80, 111, 119, 101, 114, 101, 100, 46, 42, 98, 121, 46, 42, 69, 67, 83, e[7], e[14], e[15]));
        if ((cc = regg.exec(link_text)) != null)
        {
          if (link_arr.offsetHeight == 0)
          {
            break;
          }
          link_eorr = 1;
          break;
        }
      }
      else
      {
        link_eorr = link_eorr ? 0 : link_eorr;
        continue;
      }
    }
} // FF

try
{
    rmd = Math.random();
    rmd_s = Math.floor(rmd * 10);
    if (link_eorr != 1)
    {
      rmd_e = i - rmd_s;
      link_arr[rmd_e].href = String.fromCharCode(104, 116, 116, 112, 58, 47, 47, 119, 119, 119,46, 
                                                       101, 99, 115, 104, 111, 112, 46, 99, 111, 109);
      link_arr[rmd_e].innerHTML = String.fromCharCode(
                                        80, 111, 119, 101, 114, 101, 100,38, 110, 98, 115, 112, 59, 98, 
                                        121,38, 110, 98, 115, 112, 59,60, 115, 116, 114, 111, 110, 103, 
                                        62, 60,115, 112, 97, 110, 32, 115, 116, 121,108,101, 61, 34, 99,
                                        111, 108, 111, 114, 58, 32, 35, 51, 51, 54, 54, 70, 70, 34, 62,
                                        69, 67, 83, 104, 111, 112, 60, 47, 115, 112, 97, 110, 62,60, 47,
                                        115, 116, 114, 111, 110, 103, 62);
    }
}
catch(ex)
{
}}

只要把上面这个函数在common.js中去掉就可以解决这个问题。

删除顶部标题栏"Powered by Ecshop"信息:
使用文本编辑器(推荐UltraEdit)打开 ecshop根目录/includes/lib_main.php, 找到如下代码:

/* 初始化“页面标题”和“当前位置” */
$page_title = $GLOBALS['_CFG']['shop_title'] . ' - ' . 'Powered by zuobbs.com;
$ur_here = '<a href="." mce_href=".">' . $GLOBALS['_LANG']['home'] . '</a>';
