Java Script: Using Variables in a Form

In this assessment, use the Web page called invitation.html found in the Required Resources (in the zip file called IT-FP3215.zip) to add functionality to an interactive form that generates an invitation to volunteers for an event. The file will have the following invitation message placeholder and a form below it. You will add JavaScript to the form that will allow a user to dynamically fill out the invitation.

Hello __recipientName_____!

You have been invited to volunteer for an event held by __organizationName_____ on ___eventDate_____. Please come to the following website: to sign up as a volunteer.

Thanks!

__hostName__

Hints:

The placeholders (for example the recipientName) will need to be set up as elements with an assigned id attribute. Prompt the user to enter in the recipients name, organization name, event date, and host name. Using JavaScript, replace those elements dynamically with what the user has entered in the form.

Use the forms input fields (once submitted) to store the values to JavaScript variables. Then manipulate the DOM to replace the element content dynamically.

Tip: Variable names cannot include any special characters or spaces. They cannot start with a number. They also cannot be any of JavaScripts reserved words.

Preparation

Download and unzip the IT-FP3215.zip file found in the Required Resources. It contains the initial framework for the site. All of the HTML files are located in the root directory. Images are placed in the images subdirectory; CSS files are placed under the css subdirectory. Your JavaScript external files should be placed under the js subdirectory (you will need to create it). When you submit your work, be sure to zip up the entire folder, including all of the ancillary files such as the images, CSS, and JavaScript code.

Note: This course requires you to use a text editor to complete your work. There are many free open source options on the Internet from which you may choose. See the Suggested Resources for links to free, open source text editors.

Directions

Read the Overview. Use the invitation.html file in the Resources as a template for completing this assessment.

Write JavaScript that enables the invitation to be dynamically completed using the form. Make sure to do each of the following:

Declare variables to store the input field data.

Store the input field data into the variables on form submit.

Manipulate the DOM to replace placeholder data with the variables.

Write developer comments to describe the variables being declared and explain the functions and logical blocks of JavaScript code.
