Code to display messagebox

Question

Normally I would use codes such as Messagebox.Show() to display message boxes. However after trying to host my website on microsoft azure I found out that I will get errors whenever there are codes involving the displaying of message boxes on the browser. Can anyone advice me on how I can go about in displaying message boxes such as when a login attempt fails?
