昨天遇到一个问题让我困惑了半天，window.open("url?param="+paramvalue)传递参数出现乱码，以前从没有遇到过这种问题，在客房端显示是正常的，可是到服务端就是乱码，不管用什么方式转码都不行，经过和同事一翻调试，最后想到了一个js在客户端转码的函数，escape(str);但是传到服务端仍然是乱码，必须在服务端进行解码。服务端执行request.setCharacterEncoding("utf-8");或GBK,这样传过来的参数就不用转码也是中文了。唉，总算功夫没有白费!
 window.open("WindowCustomerListAction?username="+encodeURIComponent(form1.name.value), "customerList", "width=550,height=250,scrollbars=yes,resizable=yes,status=yes");
服务端
public class WindowCustomerListAction extends AbstractAction{
