//显示搜索框
function showHide(id, on)
{
var more=document.getElementById(id);
more.style.display=(on ? "inline" : "none");
}
前段时间我老是用模态窗口来弹出新页面，但其实这并不是模态窗口的使用之处，毕竟它这样用有诸多不便之处，比如容易保持状态，需要新建更多的页面。它主要用于传入模态窗口的参数到父页面。
而使用div才是正道，无论是弹出对话框，还是搜索功能，凡是需要另开窗口的地方，使用层将很方便。
Code <script language="javascript" type="text/javascript">
//显示搜索框 function showHide(id, on) 
{ var more=document.getElementById(id); more.style.display=(on ? "inline" : "none"); 
}
