Javascript pop up that will fade away
===

I need to have a message box like thing (but with no buttons), that would display on the screen saying `All data was saved` and then fades away in 2-3 seconds.

It's like an alert, where we are alerting the user that the records have been saved. But i need it to display in a small box on top of the screen and it should fade out. 

Can someone help me with a javascript code that would do this ?

Sorry, i have any code, and hope i made my question clear.
