See these images of site Cricinfo.com.

First Image, you can see when we hover our mouse pointer on News in left column 1st row (written Afridi named…), then its Image automatically changes in Right big Column.
Same like this when we hover our pointer on second row (Sehwag "fully fit"….), then its image automatically changes in right column.

So how can we do this in JS?

Second Image: When we click on Feb 12 then its schedule immidiately comes under it. Same as when we click Feb 15 thus its schedule comes differently comes under it? How this happens in JS?

Third Image: When we click on small A, then whole text in document get changes and when we click Big A then immediately Text of whole document gets bigger. How this happens in JS?

Last Image: This image is of Yahoo! home page. When we click on any of our favorite color, it immediately changes the whole page color. How it happens in JS?

Please tell me what these functions in Java Script calls? How we can do all this in JS?

If this all happens in any other language easily than JS, then I request you to tell me that language (with function name) too.

I’ll be grateful to you for this kind act.

Happpy.
