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 assessment you will use the previously created registration.html file to send information to a second
page (interests.html) that has another form for the user to complete. You will write a script on that form that
will save the information from both forms to a cookie and then display it on a third page.
Tips:
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.
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 (interests.html (created by you)). The information should be
stored in hidden input fields (in the interests.html page) using the same field id/name. The interests page
should ask the user to enter the following in optional fields:
Interests (list at least three using a checkbox).
Newsletter sign up (radio box with a yes/no option).
Comments (free form text area).
Referred by (text field).
When the user presses submit, all of the input fields from this form as well as the registration.html form will
be saved into a cookie. The user should then be forwarded to a third 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:
Create and integrate a script on the registration.html page that stores the input field data into hidden fields to
be used in the interests.html page once the submit button is pressed.
Create an interests.html page with a form that has the fields listed above. This interests.html page will read in
the input from the query string data from the registration.html page and store them into hidden input fields.
Write a script that runs in response to the submit event, from the interests.html page, that saves the input
from both pages to a series of cookies to store each input, and opens a third page called confirm.html that
reads and displays information from all the fields.
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 and 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
