Using Arrays and Loops

Overview
In the previous assessment, you used a static set of named variables to store the data that was entered in a
form to be output in a message. For this assessment, you will use the invitation.html file that you modified in
the previous assessment to create a more effective process for entering information and creating invitations
for volunteers. Rather than having to enter each volunteer and create an invitation one at a time, you will
create a script that will prompt the user to enter in the number of volunteers, event date, organization name,
and host name. Using the number of volunteers entered (5–10), the script should loop through to ask the user
to enter the recipient name and store it in an array. Once the user has entered all of the names and pressed
submit, the page should display each of the invitations one after another at the bottom of the page.
Directions
Use the invitation.html file that you submitted in your previous assessment to add functionality to your form.
This new functionality should allow the user to enter in the number of volunteers, whereupon the form will
display the corresponding number of input fields for the user to enter information for each volunteer. Once
the form is submitted, the data should be stored in an array to be looped through to create separate invitations
for each volunteer on a new page.
Make sure to do the following:
Add an input field that allows the user to input the number of volunteers as a numeric value.
Once the number of volunteers has been entered (by pressing the enter key while the cursor is in the input
field), use JavaScript to display the volunteer input fields based upon the number of volunteers entered.
Write JavaScript that stores the form into an array of records once the form is submitted.
Write JavaScript to Loop through the array of records and then display the invitation message for each
volunteer. (Unlike a simple array that contains a single variable for each index, an array of records allows us
to store related data fields for each index in the array. If we were going to store this in simple arrays, we
would need a separate array for each data field.)
Once completed, view your pages in each of your two selected Web browsers to see if the content renders
appropriately and consistently within each. Next, verify that your code is error-free using the appropriate
browser-specific development tool found in the Resources. Take a screen capture of each of your validation
results and save it for submission.
Submission Requirements
Upload your Web site files to your Web host.
Submit your work in the courseroom using a single Zip file containing the following:
Your entire Web site, including all associated files.
A Word document with:
The url to your Web site so faculty can view your site on a live host.
A screen capture of each of your two validations that you completed using the developer tools found in the
Resources.
