        {
            text: "系统结构",
            items: [
                { text: "指标管理", icon: "ico-struct", url: "../Sysmgr/struct/Default.aspx" },
                { text: "代码管理", icon: "ico-code", url: "../Sysmgr/code/Default.aspx" },
                { text: "人员类别", icon: "ico-pcls", url: "../Sysmgr/pcls/Default.aspx" },
                { text: "区县动态", icon: "ico-remind", url: "../Sysmgr/DistrictDynamic/Default.aspx" },
                { text: "班子指标设置", icon: "ico-oper", url: "../Sysmgr/ABZMgr/Default.aspx" },
                { text: "简单测试", icon: "ico-report", url: "../Sysmgr/TestFile/Default.aspx" }
            ]
        },
        {
            text: "机构用户",
            items: [
                { text: "机构设置", icon: "ico-org", url: "../Sysmgr/org/Default.aspx" },
                { text: "角色管理", icon: "ico-part", url: "../Sysmgr/part/Default.aspx" },
                { text: "用户管理", icon: "ico-user", url: "../Sysmgr/user/Default.aspx" },
                { text: "在线用户", icon: "ico-online", url: "../Sysmgr/online/Default.aspx" },
                { text: "用户日志", icon: "ico-log", url: "../Sysmgr/logmgr/Default.aspx" },
                { text: "员工自助", icon: "ico-personal", url: "../Sysmgr/personal/Default.aspx" }
            ]
        }

如图 和代码 我想在text:"系统结构" 里面添加数据
var data1 = { text: "简单测试2", icon: "ico-report", url: "../Sysmgr/TestFile/Default.aspx" };
怎么把data1添加进去？

前端 js？ 遍历datas,找到text == "系统结构" 然后push进去的

for(var i = 0;i < datas.length; ++i) {
    if(datas[i].text == "系统结构") {
        datas[i].items.push(data1);
        break;
    }
}
