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:
HTML code
<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>

调用的两个JS文件:
tree.js
JScript code
function tree (a_items, a_template) {    this.a_tpl      = a_template;    this.a_config   = a_items;    this.o_root     = this;    this.a_index    = [];    this.o_selected = null;    this.n_depth    = -1;        var o_icone = new Image(),        o_iconl = new Image();    o_icone.src = a_template['icon_e'];    o_iconl.src = a_template['icon_l'];    a_template['im_e'] = o_icone;    a_template['im_l'] = o_iconl;    for (var i = 0; i < 64; i++)        if (a_template['icon_' + i]) {            var o_icon = new Image();            a_template['im_' + i] = o_icon;            o_icon.src = a_template['icon_' + i];        }        this.toggle = function (n_id) {    var o_item = this.a_index[n_id]; o_item.open(o_item.b_opened) };    this.select = function (n_id) { return this.a_index[n_id].select(); };    this.mout   = function (n_id) { this.a_index[n_id].upstatus(true) };    this.mover  = function (n_id) { this.a_index[n_id].upstatus() };    this.a_children = [];    for (var i = 0; i < a_items.length; i++)        new tree_item(this, i);    this.n_id = trees.length;    trees[this.n_id] = this;        for (var i = 0; i < this.a_children.length; i++) {        document.write(this.a_children[i].init());        this.a_children[i].open();    }}function tree_item (o_parent, n_order) {    this.n_depth  = o_parent.n_depth + 1;    this.a_config = o_parent.a_config[n_order + (this.n_depth ? 2 : 0)];    if (!this.a_config) return;    this.o_root    = o_parent.o_root;    this.o_parent  = o_parent;    this.n_order   = n_order;    this.b_opened  = !this.n_depth;    this.n_id = this.o_root.a_index.length;    this.o_root.a_index[this.n_id] = this;    o_parent.a_children[n_order] = this;    this.a_children = [];    for (var i = 0; i < this.a_config.length - 2; i++)        new tree_item(this, i);    this.get_icon = item_get_icon;    this.open     = item_open;    this.select   = item_select;    this.init     = item_init;    this.upstatus = item_upstatus;    this.is_last  = function () { return this.n_order == this.o_parent.a_children.length - 1 };}function item_open (b_close) {    var o_idiv = get_element('i_div' + this.n_id);    if (!o_idiv) return;        if (!o_idiv.innerHTML) {        var a_children = [];        for (var i = 0; i < this.a_children.length; i++)            a_children[i]= this.a_children[i].init();        o_idiv.innerHTML = a_children.join('');    }    o_idiv.style.display = (b_close ?
