//根据后台数据格式化菜单
function formatMenu(data) 
    return data.map(function (item) 
        if (!item) 
            return null;
        
        var path = item.path, name = item.menuName, id = item.id;

        var result = 
            path: path,
            name: name,
            id: id
        ;

        if (item.pid > 0) 
            result.exact = true;
        
        if (item.ch) 
            var children = formatMenu(item.ch);
            result.children = children;
        
        return result;
    ).filter(function (item) 
        return item
    );
