在default.aspx 页面中，有一个用户控件side_menu.ascx。这是 side_menu.ascx 中代码的一部分
<script src="../library/scripts/side_menu.js" type="text/javascript"></script>
<script src="../library/scripts/side_menu_items.js" type="text/jscript"></script>
<script src="../library/scripts/side_menu_tpl.js" type="text/jscript"></script>
<script language="JavaScript" type="text/javascript">
<!--
new menu(SIDE_MENU_ITEMS, SIDE_MENU_POS, SIDE_MENU_STYLES);
// -->
</script>
功能菜单在 side_menu.js 中定义。SIDE_MENU_ITEMS 是一个包含所有菜单项和路径的数组。
var SIDE_MENU_ITEMS =[
["Administration", null,
["Report a Bug", "administration/bugs/report_bug.aspx"], // /TOrders/
["Bug Tracker", "administration/bugs/bug_tracker.aspx?fmtid=bugs"], // /TOrders/
["Feature Request", "administration/features/request_feature.aspx"], // /TOrders/
["Feature Tracker", "administration/features/feature_tracker.aspx"] // /TOrders/
]
单击菜单项时，它会加载页面/localhost/administration/bugs/whateverpage.aspx。这工作正常。但是，当第二次单击菜单项时，路径变为/localhost/administration/bugs/administration/bugs/whateverpage.aspx。路径正在附加。我只是不知道去哪里清除阵列。当我单击菜单项时，将调用 menu_onnclick() 并且 this.item[id] 已经填充了错误的路径。不知道在哪里清除它。
这是side_menu.js中的一些功能
