望高手解答

2个问题？
1. 我的按纽 <input id="btn_UnitSet" onclick="javascript:window.open ('UnitSet.aspx?id=<%=s_A1%>','', 'height=280, width=460, top=260, left=280, toolbar=no, menubar=no, scrollbars=no, resizable=no,location=no, status=no,_blank')" type="button" value="单位设置" /> 在点击按纽后弹出UnitSet.aspx 我希望在UnitSet.aspx没关闭前，不能操作其他页面。我在UnitSet.aspx该怎么做？2.在退出页面时，我要获取退出时间来修改数据库。 我该怎么处理（哪个事件）？

解决方案 »

  1.   

    window.open改成window.showModalDialog，就等关闭后才能操作其它的关闭那种退出处理可以在body.onunload事件里面处理
      

  2.   

    showModalDialog 只能在IE下面使用！游览器不兼容。
      

  3.   

    1.window.open改成window.showModalDialog
    2.关闭就要判断很多情况,具体很多...
      

  4.   

    貌似第一个问题除了showModalDialog ，也可以通过设置焦点来解决，不过我不知道怎么写
    据说还可以用DIV模拟出来showModalDialog ，不过我也不知道怎么写
