function showsubmenu()
{
$("#submenu_1").show();
$("#submenu_1").css("currentMenu");
$(this).css('currentMenu');
}

first

second

three

four

first_1

first_2

first_3

$("#submenu_1").css("currentMenu");
$(this).css('currentMenu');

这两行怎么不起作用?没反应
currentNenu我定义在css文件时,包含进去了

只有$("#submenu_1").show();这个起作用

回复讨论(解决方案)

$("#submenu_1").addClass("currentMenu");
$(this).addClass('currentMenu');

添加 css类名用 addClass

晕,不起作用
