页面跳转问题，请大家指教，谢谢，在线等~~~~
现有一个框架页面，上下2个分别为
<frame src= "first.jsp " name= "topFrame ">
<frame src= "err.jsp " name= "midFrame ">
当我执行到以下步骤时：
out.print( " <script> alert( '出错！ ');document.location= 'first.jsp </script> ");上面的topFrame框架页面能正确跳转到first.jsp；我希望下面的midFrame框架页面也能跳转到err.jsp
我写成：
out.print( " <script> alert( '出错！ ');document.location= 'first.jsp </script> ");
out.print( " <script> window.location.target=midFrame;window.location.href= 'err.jsp '; </script> ");
不能实现预期效果，谢谢指教；

JSP也来这里问啦，哈哈，NET版人气好高啊。
try:
out.print( " <script> alert( '出错！ ');document.location= 'first.jsp ';document.location= 'first.jsp ';top.midFrame.location= 'err.jsp '; </script> ");

window.location.target=midFrame？没有见过这样的写法
out.print( " <script> alert( '出错！ ');document.location= 'first.jsp </script> ");
out.print( " <script> parent.frames[ 'midFrame '].location.href= 'err.jsp '; </script> ");
