Category: Javascript

JavaScript is a high-level, interpreted programming language used for making dynamic and interactive websites. It was developed basically to fulfill the purpose of providing interactivity to the HTML pages, form validation, dynamic content updating, and even animation effects. Today, it has grown into a full-fledged language applied in both client-side and server-side development.
### Some Key Features of JavaScript:
1. **Event-Driven**: Developers, using JavaScript, can respond to the very least end-user actions like clicks, keyboard input, and so on to socialize a webpage.
2. **Dynamic Typing**: JavaScript is dynamically typed. You need not declare the data types explicitly. The type will be decided at runtime for a variable.
3. **Object-Oriented**: Though this is not a purely classical object-oriented language, with the help of prototypes, JavaScript allows concepts of OOP, such as inheritance and encapsulation.
4. **Asynchronous Programming**: JavaScript has support for asynchronous programming through callbacks, promises, and async/await. The latter is quite essential, especially in handling I/O operations that don’t block the main thread.
5. **Cross-platform**: JavaScript does run on almost all modern web browsers and works in multiple operating systems. It is also used at the server-side, equipped with a Node.js environment.
6. **Versatility**: Besides web development, JavaScript is used for game development, mobile app development—with frameworks like React Native—and even desktop applications—with tools such as Electron.
The flexibility of JavaScript and the diverse fields it can be applied to have made it a core technology in the sphere of web development and much more.

Hello 👋 ,
check the file attachment and please read and follow the assignment rules and use APA style for reference if it was required.
Thank you 😀

In this assignment we will simulate the kind ofprocessing you will do next semester when you retrieve
records from databases using PHP. From our point of view, we don’t care how the JSON string was
created, we only need to work with it once it arrives in our client-side system.
We haven’t done an exact example of this together, but it has a lot in common with printing variables
from an array in a loop that we did in first semester. What does “

” mean? Nothing in a
Python program, and not much to JavaScript either, it’s a string. When it becomes part of the DOM, the
browser turns it into a cell in a table. This is the idea we’ve discussed a few times: syntax versus
semantics – the structure versus the meaning.
You are going to be doing exactly that: turning a string into HTML. Except where noted you may create
empty HTML elements and change the innerHTML to achieve your goals but top marks are reserved for
using CreateElement and manipulating the DOM directly. You may still need to modify attributes on
those elements, those details are up to your ingenuity.
Create a page with 3 buttons labelled “First”, “Second”, “Third”, and an input element on it. You can pick
the type of input element you feel best solves the problem.
When any button is pressed you will be sending an AJAX request to
https://csunix.mohawkcollege.ca/~adams/10259/a6_responder.php below you will find the details of
what each request should do. To work correctly with CSUNIX the request must originate on CSUNIX. If
you try to test your work from your local computer you will see a CORS error, a cross site scripting error,
will happen. To develop your solution, I suggest putting the URLs for GET requests into your brower’s
URL bar and putting the returned strings into a variable. This way you can test your code without
uploading it. For the POST request you can use a similar technique or simply test immediately on
CSUNIX.
When the first button is pressed send the AJAX request with no parameters. You should expect the
response to be text. Create a h1 element with this text and your student number. Make the text
centered in a container that fits across the entire width of the page.
When the second button is pressed send an AJAX request along with the value of the input element as a
GET parameter named “choice”. The valid values allowed by the server script are “mario” or “starwars”.
For example:
https://csunix.mohawkcollege.ca/~adams/10259/a6_re…?choice=mario You
should expect the response to a JSON string. The string will encode an array of objects. You will receive
at least 1 and at most 3 elements in the array. For each element in the JSON array create a div to hold
the content. Each attribute of the object will be a string, to keep things simple: a name, a url, and a
series. At the top of the div put the series string in an h2 tag inside the div. Below that show the image
that is linked in the url. Finally, below that put the name. The divs should fill 100% of the width of the
screen: if there are 2 elements then the divs will be 50% each, if there’s 3, 33% each. Be warned you
may have to provide height and width parameters to force the images to resize. Do not leave a blank
div, fill the entire area. It should resemble (but does not have to be the same as) these examples:When thethird buttonis pressed send an AJAX request with the value of the input element as a POST
parameter. The valid values allowed by the server script are “mario” or “star wars”. You should expect
the response to be a JSON string. The string will encode an array of objects. You will receive at least 1
and at most 15 elements. Put the elements returned in a table below the pictures, each object
containing the values for 1 row. The table tag may be hard coded in your html, but the table rows and
cells may not be hard coded and must be dynamically generated by your JavaScript code.
Below the table there should be a copyright notice that matches the content.
Place an appropriate copyright notice below the images depending on whether the input was for Star
Wars or for Mario.The copyright notice for “mario” content is:
Game trademarks and copyrights are properties of their respective owners. Nintendo properties are trademarks of Nintendo.
© 2019 Nintendo.
The copyright notice for “starwars” is:
Star Wars © & TM 2022 Lucasfilm Ltd. All rights reserved. Visual material © 2022 Electronic Arts Inc.
NOTES: that there is no guarantee the user will not change the input between button presses, so how
will you make the two pieces of content match one another? To simplify the overall situation, you may
choose to disable the input tag once one of the 2nd or 3rd buttons is pressed to avoid tracking state and
managing a more complicated situation.
The use of Bootstrap to make things look nicer is recommended, indeed, you might find it simplifies the
layout dramatically.
Responsive design is not required for this assignment but is always welcome.
NOTE: This is a college-level project DO NOT use any AI tools to write the code. It should be hand-written. DO NOT use high-level programming techniques. Please read and follow all the instructions properly and carefully.

In this assignment you are being asked to createa simplegraphical application or a game. Since we have
no back-end support, we will need to work 100% client side. You are not expected to retain any
information between page loads – high scores, etc. will reset every new page load.
Do not over complicate the program itself, it can be as simple as a heads/tails coin flipping game, a dice
game1, memory matching puzzles2, a typing tutorial, HTML tutorial (remember Super Markup Man?) or
some other simple game that you wish to create. Perhaps there’s even a Happy Chicken assignment in
your Java course that can serve as inspiration. The goal here is to practice programming, not to create a
AAA multi-million dollar hit game. The artistic standard is “good enough” not “gallery ready”. A demo
video is available at Required Elements
• Your program must meaningfully make use of SVG elements.
o These elements must be interactive using at least 2 types of JavaScript mouse events
(your choice of specific events). You may change 1 mouse event to a keyboard event if
you wish.
o These elements must have the ability to be removed: they must disappear from the
screen and be removed from memory.
o These elements must be creatable by some mechanism. Suggestions include an add
button or a timer that “spawns” them. After creation they should appear on the screen.
o You may have an initial layout of hard coded elements if desired, but all other adding
and removing of elements must be dynamic using JavaScript.
• Style your SVG elements using CSS in addition to the basic XML parameters available.
1 See http://www.activityvillage.co.uk/dice-games for some inspiration.
2 See https://www.mindgames.com/game/Memory+Trainer for some inspiration.
• Animate at least 1 SVG element using JavaScript. The animation must be obvious and
noticeable. Do not use JavaScript to add a CSS animation to an element, nor use an animated
GIFs, etc., to fulfil this requirement.
• Use standard HTML elements to establish user inputs and criteria for the program. Use at least 1
input element without a form to accomplish this requirement, in addition to any other elements
you wish. For example: change the colour of all the circles, make all the squares twice as large,
make the dice 8 sided instead of 6, make the animation move twice as quickly, etc. The specifics
will depend on what kind of program you’re creating.
• Track the state in some meaningful way – for example, a score, number of tries remaining, count
of circles created; something that is connected to your application.
• Continue to use good HTML structure by creating a header and footer around your main
content. The header or footer must contain your name and a copyright notice for 2023. The
page should be titled and appear neat and complete.
You may use Bootstrap 5 or multimedia elements, including CSS animations to make your project
visually appealing and interesting. You may not use jQuery.
• The app must run from beginning to end with no bugs or errors in the Console.
• All JavaScript and CSS code must be in separate, external files.
• The page should look ok on a phone (i.e. maximum width 320px) and on desktops as well.
• All files must be documented according to “Documenting JavaScript Programs” on the LMS.
NOTE: This a college-level assignment DO NOT use any high-level programming to write the code. DO NOT use any AI tools to write the code should be hand-written. Please read and follow all the instructions carefully. For your help and additional information I have provided Youtube video and 2 websites.

PSY-535 – Assignment 1
Identify an article from a peer reviewed journal that has been published within the past five
years. You need to have access to the full text of this article. The article should focus on any
area of psychological research and include in the content of the article information about the
author’s research hypotheses and theories on which they are based. The first paragraph should
be a very concise summary of the article, and the remainder of the paper should include your
evaluation of how well the research hypotheses are presented and justified, as well as how well
the article describes the background of the theories they used (i.e., for a reader who might be
unfamiliar with the specific theory, is the theory understandable?).
Instructions:
Your assignment must be formatted using APA Style (7th ed)–student research paper template.
Your paper should be no more than 2 pages (not including the title page or references page),
and include at least three peer-reviewed academic references. You are also required to submit

Display the output on the screen and work with variables
TIME TO COMPLETE
One week (16 weeks classes) – 1 period about 3 days (short term classes)
HOW TO DO EACH PART
Do the lab with the following:
STEP1: CREATE THE PSEUDO-CODE AND LEARN JAVA SYNTAX
1. Read the lab requirement then figuring out: -What does the requirement ask for? -Then, figure out and list step by step in English what do you need to do to come up the final solution (in a word document)that must be qualified to the requirement. This document is called as the pseudo-code.
2. Learn the Java syntax to translate each English step in the pseudo-code to Java language (that means write the java code). If you need help on this step, read the topics relating to the action of each step in HOW TOT DO LAB to learn the java syntax. For example, the lab requirement asks you to display something on the screen, then you can read the topic “How to display output on the screen” in the HOW TO DO LAB.
3. When you are ready with java syntax that needs for the lab, you bring up the eclipse or other editor to start writing java program.
STEP2: CREATE THE JAVA PROJECT AND WRITE THE JAVA CODE
*From now and on yourLastName will be changed to your last name
*Your program should change Martinez to your last name
*Change LUIZ MARTINEZ to your full name
*write the file name as the first comment line at the top of program. The java comment line starting with // as the comment line in java
*After running your program successfully, take the picture of the output window and paste the picture at the bottom of the document having pseudo-code to turn in
1. Start editor eclipse, create the project à write the project name Project name of the Part 1: SP2024_LAB1PART1_yourLastName Project name of the Part 2: SP2024_LAB1PART2_yourLastName
2. Add the driver class that includes the function main(). Class name will be the file name.
Part1: add the driver class with the name as SP2024_DisplayOnScreen_yourLastName
Part2: add the driver class with the name asSP2024_ProgramWithVariables_yourLastName
⇨ An empty window is coming up that is ready for you to write java code
3. In the empty class, type the following template of a java program in:
For example with the Part1 (yourLastName should be changed to your last name
//File name: SP2024_DisplayOnScreen_yourLastName.java
public class SP2024_DisplayOnScreen_yourLastName {
public static void main(String[ ] args)
{
//add the code here below this line
…..
}
}
STEP3: COMPILE THE CODE AND FIX THE ERRORS STEP4: RUN THE PROGRAM
*With eclipse, the project will be automatically compiled, creates the object file .class then run to provide the output on the Console window if the code with no syntax errors.
LAB1 PART1 REQUIREMENT
Using java to provide the application to display the following output in 12 lines:
LAB1 PART2 REQUIREMENT
Provide the pseudo-code and a java program to allow users to enter their own required information from the keyboard. (That means the program should read input from the keyboard)
-The users should be asked to enter from the keyboard to provide two words, and 3 decimal numbers to the application.
-After reading the above input, the application will display the output on the screen with the following information and in the following format:
For example, If users provide input from the keyboard:
-2 words: Test and Hello
-3 numbers: 87.6, 76.5, 65.4
Then the output will be in 11 lines as below:
HOW TO TURN IN THE LAB
ATTENTION: Compress each project folder into a file .zip or a file .rar. that includes source files and class files.
-If you do not have the source file and class file, your lab gets 0 points
-If you do not provide file .class of the part, you only have half of the max score of the part
You should turn in the following files:
1.Lab1_pseudoCode_yourLastName.docx(includingPseudo-code and the output pictures of both parts)
2.SP2024_LAB1PART1_yourLastName.zip (including file SP2024_displayOnScreen_yourLastName.java and file SP2024_displayOnScreen_yourLastName.class)
3.SP2024_LAB1PART2_yourLastName.zip (including file SP2024_ProgramWithVariables_yourLastName.java
and file SP2024_ProgramWithVariables_yourLastName.class)
