项目中菜单折叠问题

思路:根据访问的路径动态的设置菜单的折叠。前提是同一级菜单放大同一文件夹下面，根据文件夹的名字动态的设置菜单的class属性。

例如:

　　我的一个url:

http://localhost/Exam/view/outDepart/outdepartEmpManage.jsp

 

　　location.pathname获取到除去ip与端口的地址　　/Exam/view/outDepart/outdepartEmpManage.jsp

$(function() {
    var u = location.pathname;

    u = u.substring(11, u.length);
    var fir = u.indexOf("/");
    var filename = u.substring(0, fir)
    // 删除class
    $(".mtree-active").removeClass("mtree-active mtree-open");
    if (filename == "innerDepart") {
        // 检索内部的url
        $(".mtree a").each(
                function(i) {
                    var url = $(this).prop("href");
                    if (url.toString().indexOf(filename) > 0) {
                        $(this).parents("[class^='mtree-level']").css({
                            display : "block",
                            height : "auto"
                        });
                        $(this).parents(".mtree-node").removeClass("mtree-closed");
                        $(this).parents(".mtree-node").addClass("mtree-open");
                        $(this).parents(".mtree-level-1").children(
                                ".mtree-open").addClass("mtree-active");
                    }

                });
    } else if (filename == "outDepart") {
        // 检索内部的url
        $(".mtree a").each(
                function(i) {
                    var url = $(this).prop("href");
                    if (url.toString().indexOf(filename) > 0) {
                        $(this).parents("[class^='mtree-level']").css({
                            display : "block",
                            height : "auto"
                        });
                        $(this).parents(".mtree-node").removeClass("mtree-closed");
                        $(this).parents(".mtree-node").addClass("mtree-open");
                        $(this).parents(".mtree-level-1").children(
                                ".mtree-open").addClass("mtree-active");
                    }

                });
    }else{
        // 检索内部的url
        $(".mtree a").each(
                function(i) {
                    var url = $(this).prop("href");
                    if (url.toString().indexOf(filename) > 0) {
                        $(this).parents("[class^='mtree-level']").css({
                            display : "block",
                            height : "auto"
                        });
                        $(this).parents(".mtree-node").removeClass("mtree-closed");
                        $(this).parents(".mtree-node").addClass("mtree-open mtree-active");
                    }

                });
    }
