Thanks for the reply! Actually I'm bad in English, Sorry for the inconvenience. By the way, This is what I wanted to know, see here in <img> tag, src image is "pic_bulboff.gif", only and this is normal that it refers to Turn off the light button. But where is the "pic_bulbon.gif" image source that can refer to Turn on the light button? What do you think, is it a magic or anything else that I don't know, Please? Note: I'm going to practice with same codes in Notepad++ to make something like that and yes, I got a nice result without only an issue, that, there isn't any impact by clicking on Turn off the light and Turn on the light button. I saw, it is going to show me the result by depending on the source image (such as src="images/pic_bulboff.gif") between the buttons. So, with same codes how is that possible there to turn on or turn off light in Tryit Editor ? My result from notepad++ below...

Hello friends!. This is my first time to learn Js. I'm confused to get this codes. See the attached image. I've seen there an image called pic_bulboff.gif in img html tag, that I marked with red color. Unfortunately, I didn't find any HTML tag with pic_bulbon.gif back there in this Tryit Editor , (I marked by green) Even how is it possible to show this image {pic_bulbon.gif) there by clicking on the " Turn on the light" button? Thanks in advance.

Thanks, davej. It is helpful for me.

I didn't know about Coda, This is my first time I heard like that. Mainly I'm newbie in Web Designing. Many thanks for this information.

I think you must search on Google to find many example there. I've found another one here in this tutorial.
