Visualforce - Beyond Basics Series 34 - Build own Alert Box

What is alert box ?

Alert box is a small container which displays user message in blocking mode that means user can't do any other action in the window.

Is there any standard way of doing it ?

As of now, there's no standard component to display the alert box in the page.

How to build a custom one ?

Traditionally, developers use window.alert function to display the box in the page. This is done different places in the project & it looks very cluttered to go through the code.

What are the alternatives ?

Some developers like to use some dialog box from javascript libraries like Jquery, Backbone in blocking mode. Though, it will give the necessary functionality, it's an additional overhead in the page.

Where is the code ?

Any screenshots ?
