ECSHOP模板默认模板页面每次刷新页面都会有个powered by ecshop字符在菜单栏中，位置随机变动，原因是在/js/common.js文件中，给页面的onload事件添加了一个随机写入powered by ecshop的标识，解决方法是，编辑/js/common.js文件，找到以下代码：
onload = function()
{
    var link_arr = document.getElementsByTagName_r(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[i].href;
      if (link_str.indexOf(String.fromCharCode(e[22], 119, 119, 46, e[4], 99, e[18], e[7], e[14],

删除这段代码就行了。
唉，ECSHOP也算是知名的开源网店程序，做这种妨碍用户操作的小动作确实不应该，不过也幸好是开源产品，不需要咱们可以删除它：）
