对于dojo不是很熟的我，提个简单的问题:

<script type="text/javascript"><!--
popup_window=function()
{
  var newWindow = window.open('/TatHome/external.svc?page=admin%2FAdminViewTeacherInfo&sp=l1041', 'TeacherInfo', 'top=10,left=10,width=830,height=700,scrollbars=yes,resizable=yes');newWindow.focus();
}
;
dojo.require("tapestry.event"); //此处firebug错误提示 dojo is not defined
popup_window_0=function()
{
  var newWindow = window.open('/TatHome/external.svc?page=admin%2FAdminViewTeacherInfo&sp=l1040', 'TeacherInfo', 'top=10,left=10,width=830,height=700,scrollbars=yes,resizable=yes');newWindow.focus();
}
;

popup_window_1=function()
{
  var newWindow = window.open('/TatHome/external.svc?page=admin%2FAdminViewTeacherInfo&sp=l1039', 'TeacherInfo', 'top=10,left=10,width=830,height=700,scrollbars=yes,resizable=yes');newWindow.focus();
}
;

popup_window_2=function()
{
  var newWindow = window.open('/TatHome/external.svc?page=admin%2FAdminViewTeacherInfo&sp=l1033', 'TeacherInfo', 'top=10,left=10,width=830,height=700,scrollbars=yes,resizable=yes');newWindow.focus();
}
;

// --></script>

在页面中运行时，popup_window是可以触发的，而popup_window_1,popup_window_2确无法触发，本人感觉是这段代码导致的问题，所以去掉后，是可以触发其他两个的，所以我想了解生成该段代码的机制，为什么会在那里生成“dojo.require("tapestry.event")”，还请有遇上类似问题的兄台指点一二。

原来添加的该代码和tapestry有关，问题已得到解决
