Needs to be javascript.
Design and build a program that allows a user to enter a series
of names in a text box within a form on a web page. The names are
entered one at a time, with the user clicking a submit button to
process each name. Remember, the click of the submit button
is what will run your program.
The names are stored in an array as each name is entered. As new
names are entered and added to the array, display the names in an
HTML table below the form. Displayed above the table there must be
a total of how many names have been entered. This total will be
calculated from the names in the array and not with a counter.
Program modules must be used for clarity and ease of future
maintenance, although no specific number of functions is mandated
as long as there are at least two. For full credit you must display
the entire contents of the array each submit. But only the contents
of the array should be display. Do not display individual elements
in the array more then once.
