"Please Wait" messages are an excellent way to let the user know that your web based application is performing some action, such as loading a page or processing data. Without such a notification, users may begin clicking other controls on the web page, or close the browser due to the excessive delays.
Pressing the button below will simulate a lengthy function or calculation. While the function is calculating, a "Please Wait" message will be displayed. This is done using a DIV area. When the function begins the DIV area is shown and when the function ends, the DIV area is hidden.
