Assignment Title: Tic-Tac-Toe game using JavaScript

PROBLEM STATEMENT 

1. Create two variables called playerX and playerO. Set them to the DOM element with the id "x" and "o" respectively. This is the text at the top that says who's turn it is.

2. Create a named function with a meaningful name of your choosing. (This will be referred to as the "event handler" in further instructions.) In this   function add a console.log() statement to display a message in the console.

3. Create a variable that contains all of the TD elements. Use a for loop or the .forEach() method to add the function as a click event handler to each of the TD elements. Be sure to use.addEventListener() rather than older methods of adding event handlers.  Open the console and click a square. You should see the message from your console.log.

4. In your event handler, add a statement to get the id value of the element with the class "current player" and store it to a variable. Display this value using the same console.log() you already have. Try clicking a square to see the value.

5.  At the end of your event handler, add a statement to switch the "current-player" class from the playerX to playerO elements or visa-versa. (Remember you can toggle classes.) Try clicking a few squares, you  should see the player at the top of the page change as well as the output in the console.

6. In your event handler, add a statement to add the class "x" or "o" to the target element depending on who's turn it is. (the target element is the one that was clicked on. Hint: the event object has a target property.) You should see "X" or "O" appear in the square when you click on it. (The letter is displayed using CSS, refer to that file if you want to see how it is done.)

7. Add an event handler to the "New Game" button to clear all the squares.

8. Notice that if you click on a square that is taken by the other player, the marker may turn into a question mark. This is because you have added both "x" and "o" classes to the document. If you used className instead of classList you would be able to take over another player's square. Also, if you click on your own square you waste your turn. Modify the eventhandler to check to see if there is a class on the element already.(Hint: this is a good use of className but there are other ways to do it.) Don't put a marker or count the turn if the square is already taken.

9. Notice that there is a file called winner.js already referenced from the HTML file. This contains a function called checkWin(). Since it is included before the main.js file, you can call this function from your code. You can examine this function so that you understand how it works. Call the checkWin() function from the event handler. The first argument is a string identifying the player, "x" or "o". The second argument is the list of td elements you selected previously.

10. If there is a winner the checkWin() function will return an array of  the winning elements, set the background colour to yellow of the three winning squares to highlight them and open an alert box to say who the winner is. Depending on which browser you use, you may not see the last markeror the highlight color until you close the alert box. This is fine. There is a trick to fix this but don't worry about it.

11. In the event handler for the "New Game" button, add code to  remove the background colour.Play Tic Tac Toe!

Solution

In our program or design [Tic Tac Toe Game], at first, on the webpage, there is a selection box with the game title and two buttons which are labeled as “Player(X)” and “Player(O)”. Users must select one option or button to continue the game. If the user selects the X then the bot will be O and if the user selects the O then the bot will be X. Once the user selects one of them, the selection box will disappear and the playboard is visible. In the above  image we show the X player is  winer and below the image show the Player O is winer. At the center of the webpage, there is a tic tac toe play area with nine square boxes. Once you click on the particular box then there is visible a sign or icon which you have chosen on the selection box. Once you click on any box then after a couple of seconds the bot will automatically select the box which was not selected by you or the bot before, and the opposite icon is visible there means if your icon is X then the bot will have O.Once a match is won by someone, the playboard section will stop and the result box appears with the winner's sign  and change background color.

Assignment Title: An Online Car Rental System

PROBLEM STATEMENT 

• The website should be dynamic which means all the data is loaded dynamically from theJSON file. If the contents in the JSON file change (e.gThe mileage changes to 12354 forid=1), the pages should change as well.

• The vehicles available for renting can be divided into three categories: Sedan, Wagon andSUV.

Car image samples are provided on the CANVAS

You need to create a folder “images' 'that stores the pictures for the cars. Each image is named according to the model of the car and the image types are all “jpg”.

Assignment Specification

This assignment requires that you do the following steps:

• Design a JSON file “cars.json” with the structure specified in requirement 3 and store at least 10 + car data items in the JSON file. Set up the availability state to “True” for 70%of cars in the Warehouse, and a “False” state to the other 30%

• Use AJAX to load the JSON file “cars.json” and extract the data and save it as arrays in your webpage.

• Display the cars in a nice tabular format using the above arrays on your webpage for users to select.

• Provide a “button” to add the car to the reservation “shopping cart”. Use AJAX to check the availability of the car after clicking the button (the field “availability” is included in cars.json). If the availability is “True” then add the car to the reservation shopping cart and prompt success; If the availability is “False” then alert that “Sorry, the car is not available now. Please try other cars' '.

• Provide a button/link to view the reservation shopping cart. Display the cars which have been added into the reservation shopping cart (hint: use session to store the data). Users can set the “rent days' ' or delete cars in the shopping cart.

• Provide the checkout button to check if there are cars in the shopping cart. If no, then alert“No car has been reserved.” and jump to the first page. If yes, validate the “rental days” (integer, >0) using JavaScript and navigate to the next page.

• Design the checkout page which displays a purchase form asking the user to fill in their delivery details (name, email address, mailing address, city, state, post-code and payment type). All these fields must be completed for the order to go ahead. Validate the format of the email address. If all details are filled correctly, then direct the user to a page showing the delivery details and the cost.

The problem with the current system is that students take their exam manually. This outdated system will take long time utilization; the manual procedure used for conducting exams is a time consuming process. More time is being used for lecturers to bring the questions papers and answer sheets and also more time is needed for students in order to write their exam. Students are not satisfied with the current system of taking the multiple choice examination. The no accuracy with current system when students did not use a 2b pencil student are losing their mark. Using the manual procedure of conducting examinations we are not saving the environment by using more paper, we are in a world where we really need to take care of the environment.

Solution

This project is aimed at developing an online examination system for introduction to management for students and lecturers.
