- A centered, readonly textbox with the label "Offer" and a maxsize of 7 digits. The
offer box should be initially blank.
- Underneath the offer box should be a
2x5 table with 10 buttons, labeled from 1 to 10. The buttons
represent suitcases with hidden monetary values. The 10 possible values for
each suitcase are $.01, $1, $5, $10, 100, $1000, $10000, $100000, $500000, and
$1000000. The values will be randomly assigned to the 10 suitcases. You should feel
free to devise your own algorithm for doing this, but one acceptable way is to
use the Math.random function, which returns a floating point
number between 0 and 1. Generate 10 random numbers and place them in an array.
For each random number determine its numeric position in sorted order and assign
it the corresponding value from the money array. For example suppose the random
number .506058 is the third generated random number and it is the 6th largest value
overall. Then button 3 would be assigned the value $1,000 because $1000 is the 6th
largest value in the money array.
- Next to the 2x5 table should be a vertical 1x10 table with 10 checkboxes, labeled with
the amounts from $.01 to $1000000.
- One centered buttons labeled "Deal"
Here is how the game works:
- The user presses the "Start Game" button and the gameboard is initialized by
assigning values to buttons and unchecking and enabling all checkboxes (the user
may have already played the game and is starting a new one).
- The user selects a button. This is their "suitcase" and they may either hold it
to the end of the game, in which case they receive whatever monetary value the
suitcase holds, or they may sell the suitcase to the banker at some point during
the game (how this might happen will be discussed shortly). Once selected,
the button should
be disabled, the text should be displayed in silver, and the button should be
colored blue. The offer box should remain blank.
- The user selects one suitcase button at a time and when the button is selected its value
is revealed by replacing the button's number with the value of its suitcase. The
button is disabled and its background color should be made yellow. The checkbox
associated with that amount is checked. To prevent the user from
clicking the checkboxes and inadvertently checking them, you can
have the onclick event call a function that returns false. This will
allow the user to click the checkbox but prevent the checkbox from
toggling its value (i.e., if the checkbox is not yet selected, then it
will remain unselected, and if it is selected, then it will remain
selected).
You can also try setting the
"readonly" property but Firefox inconveniently ignores this property.
- After each button is selected the banker makes an offer in the offer text box.
The offer should be computed as 90% of the expected value of the remaining unopened
suitcases, because that is what happens on Deal or No Deal--the banker always
lowballs the offer until there are only a couple of suitcases left. The offer should
be an integer.
- The user selects either the "Deal" button or another suitcase. If the user selects the "Deal" button the game ends and the value in the user's suitcase is revealed. If the user selects another suitcase the game continues with a new offer. If the user has opened all the suitcases the game automatically ends and the value in the user's suitcase is revealed. No matter how the game ends, an alert box should pop up telling the user how much the user won. If the user selects the deal, the user wins whatever the offer amount is, not what is in the suitcase.
- You will need to use javascript and jquery to implement
this front-end and you will modify the .php scripts that took
command line arguments in the previous homework assignment so that
they now can be called from your front-end. The scripts should
now take their input from the posted form data.
- You will need to transition from your login page to your
results page once the instructor is authenticated. You can do
this in one of two ways:
- Use the document.location.href to redirect the web-page's location to reservations.html.
- change your reservations.html page to a reservations.php page and have your authenticating php script output this page.
- If the user inputs a bad id or password, then use javascript to add a message to the front page saying that the authentication failed due to either a bad id or password.
