Here are some of the topic we will cover! I'm so excited you decided to take the initiative to improve your core Web Development skills! This application will be able to load questions from a 3rd party API, track and display high scores, and so much more!

In this video, we are going to create the home page along with a good chunk of the necessary CSS. The home page will consist of a few links for the Game and High Scores pages. We will also create helper CSS classes for Flexbox, buttons, and hiding elements.

In this video, we will create the Game Page and display static question and answer information.


Eventually, we will load questions from an API, but for now, we will hard code one question so to establish styling.

In this video, we will load questions from a hard coded array and iterate through available questions as the use answers them. We will use custom data attributes, the ES6 spread operator, and JavaScript arrow functions. In this video, we check the user's answer for correctness and display feedback to the user before loading the next question. This will display the user's score and current question number.

In this video, we will take our HUD one step further by creating a visual progress bar to track the user's progress through the questions. In this video, we will create our End page where we will display the user's achieved score. This screen will provide a form for saving the score and links for playing again or going home. In this video, we will save and maintain a high scores array in Local Storage. To do this, we will need to JSON.

In this video, we will create our High Scores page. We will have to load the high scores from Local Storage, iterate through them, and display them on the screen. In this video, we will move our sample questions from a hard coded array to an external. This will help clean up our Game. Thank you so much for going through this course. I truly hope that you enjoyed it and that you have improved your core Web Development skills!!

Home page is the landing page of the application from where a user can take any quiz by clicking on the quiz. On the home page, if the user is logged in his name is also shown and a logout link is provided to logout from the application. On starting a quiz, a user is presented with the first question of the quiz with the next and finish button.

Note that the previous button is not shown when the user is on first question and next button is not shown when the user is in the last question.

After clicking on the finish button the user is presented with exam results, showing the name of quiz; time when the quiz was started and the number of questions that the user answered correctly. Well, it works as you expect it to work. If the user is not logged in, the user will automatically be redirected to the login page, where the user can login. Now, the user will be presented with the first question of the quiz.

To move through the quiz questions, the user is provided with the next and previous buttons. The quiz can be finished at any time by clicking on the finish button. Home page is pretty straightforward. We have a menu and 8 images displayed in a table format with two rows; each row containing 4 images.

On the home page we also make a check, whether the user is logged in or not. If the user is logged in we also display the username and provide a logout link. There is nothing fancy in the registration page; just an HTML form awaiting the user to provide his name, email and password.

Once we get that, we pass this to RegistrationController servlet to create an account. Note: We are not doing any validation like password should contain 8 characters with at least one uppercase character, one number and special symbol. We will do that in upcoming posts, when we extend this application. In this application we have used MySQL database to store user credentials. To get a connection to database we have defined a static method createConnection in DatabaseConnectionFactory class, where all database specific information is stored.

If you are working with some other database like Oracle you have to change the properties of the DatabaseConnectionFactory class accordingly. Login page is very much similar to registration page where we are providing two input fields asking user to provide a username and password. Once we get the username and password entered by the user we pass it to LoginController to authenticate user.

It is the MainController where we have written the code to redirect the user to appropriate page according to the incoming request url.

Objet ' on a null object reference. Now what i understand is, that at somepoint java expects a positive figure while it's a null. Am i correct?

Live Demo. I like your approach with regards to separating display from logic. Keep thinking this way and you will end up with more re-usable and maintainable code. Since you are, in essence, building out a Quiz class, I would think you should consider implementing your various properties and methods in more "class-like" manner not necessarily ES6 type classes, but something ES5 compatible like I have shown below.

This would allow for higher level of re-use for your Quiz class i. I don't see great need to store the jqxhr reference in request here. It seems odd to have callbacks against the request jqxhr object split across different areas of your code.

If all that is happening with this request is that you retrieve the JSON for question configuration, why not just execute and store the questions on the object and then not have to maintain reference to request and pass questions around between methods? You could even unset and make that memory available to garbage collection immediately after callbacks are processed. If you take the approach noted above and store element refences on object as well as question information on object, all of your public class methods could change signature to not require parameters to be passed.

If you take suggestion of moving this to more "class-like" structure, you would need to replace references in your methods from Quiz the class to this the instance. I would consider separating the logic on grading or evaluating the question from the logic to navigate between questions. Right now both occur in handleQuestion method.

Perhaps handleQuestion should just call a method like nextQuestion which hold the logic for next question.The test is not official, it's just a nice way to see how much you know, or don't know, about JavaScript.
