Overview
In this
assignment, 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 functionality 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 on July 1st. Please respond to this
email 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
recipient’s name, and host name (Your name). Using JavaScript, replace those
elements dynamically with what the user has entered in the form.
Use the
form’s input fields (once submitted) to store the values to JavaScript
variables. Then manipulate the DOM to replace the element content dynamically.
To get you
started, in your .js file, you need to first declare the variable names such
as:
var
myRecipientName;
Then, you
would need to set the variable to the input field’s value:
myRecipientName
= document.getElementById(“recipientNameInput”).value;
Next, you
would then need to set the innerHTML of the span element of the corresponding
name like:
document.getElementById(“recipientNamePlaceholder”).innerHTML
= myRecipientName;
Note on
your submit button, a JavaScript event handler has been defined on the submit
of the form. Notice that it has a return false to prevent the form from
actually submitting.
Hint: See what
happens when you remove the “return false” from the JavaScript code.
Tip:
Variable names cannot include any special characters or spaces. They cannot
start with a number. They also cannot be any of JavaScript’s reserved words.
Remember as well that JavaScript is case sensitive.
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” subdirector. 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.
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 all
your website files to a hosting service of your choice. Two free sites to
consider are Freehosting.com or 000webhost.com. See the Suggested Resources for
links.
Submit your
work in the courseroom using a single Zip file containing the following:
Your entire
Web site (including the updated “invitation.html” file).

Unit 02 Assignment
Using
Arrays and Loops
Overview
For this
assignment, you will use the volunteer.html file to create a more effective
process for managing the volunteer list by using arrays and loops. The web
application will make use of the volunteer.js file and allow the user to add
volunteers, delete volunteers, clear the list of volunteers as well as sort the
volunteers. Some of the functionality has been created to start you off so that
you can see how it is all integrated. You will be focusing on the code to
delete the volunteer as well as alter the volunteer list to add some formatting
on the output. Functionality is also included to be able to sort based on the
volunteer’s last name.
Directions
Use the
volunteer.html file to add functionality to our form. This new functionality
should allow the user to enter in volunteers to be added as well as delete
volunteers from the list by re-entering in their name. The volunteer list
should also be altered to use a looping structure to display a running count of
volunteers beside each name (starting at 1) beside each name similar to the
following display:
1. John
Smith
2. Jane
Willow
3. Randolph
Jack
4. Jen
Stevens
Hint: Use
the splice function in order to remove a specific item from the array.
Tip: The
array index starts at 0, so when displaying the index, you will need to add 1
to the index value when it is displayed.
Make sure
to do the following:
Write
JavaScript to delete a specific volunteer by using loop.
Write
JavaScript that loops through the volunteer list to display the index value.
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.

Unit 03 Assignment
Dynamic
Images, E
vents, and
the DOM
Overview
Images,
both static and dynamic, appear on most Web sites. There are many different
features and functionalities that we can add through the use of JavaScript,
including preloading, rollovers, and cycling banner ads. In this assignment,
you will work with JavaScript, images, events, and manipulating the DOM to
create an interactive image gallery.
Hint:
Preloading your images will only work on a hosting server and not your local
drive, as there is no load time for your images locally. Once you have
preloaded those images, you should clear your cache to test your loading of the
images again.
Tip: In a
smaller JavaScript program such as this one, each function is created for a
specific purpose. However, in more complex sites, it is better to build
functions that are applicable to multiple situations. For example, rather than
specifying an element name or ID, we can use a variable that is passed into the
function.
Directions
Use the
gallery.html and index.html files from the supplied course Zip file. Create
functionality using JavaScript on the following pages:
index.html
Preload the
images (banner1.jpg, banner2.jpg, and banner3.jpg in the images folder) for the
banner at the top of the page.
Create a
cycling two-state banner that cycles every three seconds.
gallery.html
Preload the
gallery images.
Create
roll-over functionality for each of the thumbnails in your image gallery. Use
appropriate images found in the images folder.
Write
developer comments to describe the variables being declared and explain the
functions and logical blocks of JavaScript code pertaining to the gallery.
Make sure
to do the following:
Create an
onpageload function to preload all of your images.
Create a
modularized function to cycle the homepage banner.
Create a
modularized rollover function for gallery images.
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.
Note:
Modularized refers to creating components that can be repurposed without
significant changes to coding. Modularized components have no “hard
coding” of image names, URLs, and so on, in the functions. Samples of
modularized and nonmodularized JavaScript are provided in the Example Code file
linked in Resources.
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

Unit 04 Assignment
Form Field
Validation and Error Messages
Overview
You have
created a basic form and added interactivity to images using JavaScript. Now it
is time to validate information entered into your form fields. You will use the
“registration.html” file found in your Zip file. You will see that
the page has a form with the following fields to allow users to register for an
account. The items in parentheses are defined formatting instructions to be
observed for each field.
Username*
(must only contain letters and numbers)
Password*
(minimum of 8 characters)
PasswordVerify*
(minimum of 8 characters, must match password)
FirstName*
(text string)
LastName*
(text string)
Email (uses
xxx@xxx.xxx format)
PhoneNumber
(uses (xxx) xxx-xxxx format)
SignUpNewsletter
(radio box for yes/no)
Tips:
JavaScript
is case sensitive, so a variable named myVar is different from MyVar and myvar.
Perform
your form validation testing as you go rather than all at the end. It will be much
easier to fix the error if you have a smaller sequence of code to review.
Directions
Read the
assignment overview.
Use the
registration.html file to add functionality to the form found on the page. The
JavaScript that you write should validate each field and, if errors are made,
display appropriate error messages that direct the user to complete the form
properly. Once the form is completed, your script should open the confirmation
page (confirmation.php).
Note: The
input fields in the form with an asterisk are required fields.
Make sure
to do the following:
Write
JavaScript that defines that a field is required and generates an appropriate
error message if the field has not been completed.
Write
JavaScript to validate all input fields per the formatting definitions that the
field values should be checked against (found in the overview) after each
field.
Write
JavaScript that displays an appropriate error correction message (next to the
field) in the event a form entry error has been made.
Write a
JavaScript that will default the user’s cursor to the first erroneous input
field in the event that there is an input error.
Create a
submit button that executes the validation when submitted.
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.

Unit 05 Assignment
Query
Strings and Storing Persistent Information
Overview
As Web
forms get longer, we very commonly see them split across multiple pages to
collect all of the necessary information. There are different reasons for this.
A long form can be daunting for users and a large/long form can be difficult
for users to fill out on a mobile device. These forms need to be designed so
that the data entered by the user on the forms on each page will be submitted
to the Web server simultaneously. This makes more sense as they are part of the
same data set. The problem with stateless pages is that if the user moves from
one page to the next, the data entered is lost. To bypass this issue, you will
need to use query strings, hidden input fields, and cookies.
In this
assignment you will use the previously created registration.html file to send
information to a second page named confirm.html. You will write a script on
that page that will save the information from the form to a cookie and then
display it on a same page. If the user goes back to this confirm.html page, the
page should display the user form data from the registration entry that was
last entered.
Tips:
o It will help to output the array
into the browser console so that you can verify that the string is being
correctly parsed. Details on the browser console can be found in the Resources.
o To skip having to enter data into
the form each time to test, it may help to create a JavaScript function that
automatically fills in the fields for you and comment it out when completed.
Directions
Read the
Overview.
Modify the
“registration.html” page created in the prior assessment to send a
query (that has all input field information from that form) to a second page.
When the user presses submit, all of the input fields from the
registration.html form will be saved into a cookie. The user should then be
forwarded to a second page (confirm.html (created by you)) that will read the
cookie information and display it in a name/value pair using JavaScript.
Make sure
to do the following:
o Create and integrate a script on
the registration.html page passes all of the input fields from the form when
the submit button is pressed.
o Create a confirm.html page will
read in the input from the query string data from the registration.html page
and store them into variables first.
o Write a script that runs in
response to the submit event, that saves the input from the
registration.html page to a series of
cookies to store each input, and opens a second page called confirm.html that
reads and displays information from all the fields.
o 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.
