jq 基础

JScript code

    <script type="text/javascript">        $(function () {            $("#tabs").tabs({ event: 'mouseover' });            $("#categoryTree").treeview({ collapsed: true });        });</script>

问题：
1.("#tabs") 是一个DIV ，.tabs({ event: 'mouseover' }) 这一段是什么意思？
2.treeview({ collapsed: true }); 这一段是什么意思？

谢谢

HTML code

        <div id="navbar">            <div class="banner">                <div class="tabbar">                    <div class="tabs">                        @{var ctrl = ViewContext.Controller;                          string action = (string)ViewContext.RouteData.Values["Action"];}                        @Html.ActionLink("首页", "Index", "Home", null, (ctrl is HomeController) ? new { @class = "actived" } : null)                        @Html.ActionLink("栏目1", "Index", "Video", new { id = "pubdate" }, (ctrl is VideoController && (!new[] { "HotVideos", "Search", "Upload" }.Contains(action))) ? new { @class = "actived" } : null)                        @Html.RouteLink("栏目2", "Paging", new { action = "Index", controller = "Album", id = "0" }, (ctrl is AlbumController) ? new { @class = "actived" } : null)                        @Html.ActionLink("栏目3", "HotVideos", "Video", new { id = "" }, (ctrl is VideoController && action == "HotVideos") ? new { @class = "actived" } : null)                        @Html.ActionLink("栏目4", "Search", "Video", null, (ctrl is VideoController && action == "Search") ? new { @class = "actived" } : null)                        @Html.ActionLink("栏目5", "Index", "Admin", null, (ctrl is AccountController || ctrl is AdminController) ? new { @class = "actived" } : null)                    </div>                </div>                <div id="dvAccountInfo">                </div>            </div>            <div class="bar">            </div>        </div>

[解决办法]
1，给每个tab绑定onmouseover事件，鼠标滑过切换选项卡
2，设置categoryTree的treeview折叠状态为关闭
[解决办法]
应该倒入了easyui或者其他基于jq的插件了，自己找这个插件的api来看
