JSP页面引用JS文件无效
引用的一个树的程序，不知道为虾米无效捏？请各位大师帮看下.^_^
JSP页面:
<table width="80%" border="0" align="center" cellpadding="0" cellspacing="0"> <tr> <td><script type="text/javascript" src="../js/tree.js"></script> <script type="text/javascript"> var TREE_ITEMS = [ ['频道管理','channelManage.jsp'], ]; </script> <script type="text/javascript" src="../js/tree_tpl.js"></script> <script type="text/javascript"> new tree (TREE_ITEMS, tree_tpl); </script> </td> </tr> </table>
