开/关开关x 2 - 适用于三种状态。 [英] On / Off Switch x 2 - for three states.

问题描述

我有一个简单的div，其中包含一个已关闭的灯泡的平面.jpg图像，我需要在此div中添加2个开/关按钮，这样当用户点击第一个时，将会有一个.png伪造的白色发光（表示灯泡已打开），当他们点击第二个按钮时，红灯（再次，假的.png效果）将显示灯泡正在充电。



有人可以推荐一种方法来做这个或一个好的代码吗？



非常感谢！

I have a simple div which contains a flattened .jpg image of a lamp that is switched off, i need to add 2 "on/off" buttons to this div so that when the user clicks the first one there will be a .png of a faked white glow (indicating the lamp being turned on), and when they click the second button the red light (again, fake .png effect) will show the lamp being charged.

Can anyone recommend a way to do this or a good code?

Many thanks!
