pixar-art's Introduction

Pixart

For this assignment you'll be creating a Javascript painting app. When you're done, it should display this functionality.

Use the starter code and commit each step of the exercise.

  • Fork and clone this repo.
  • Checkout a new branch called 'YOUR-NAME-solution'
  • Work in small steps and commit frequently.
  • When you're finished, push your solution branch to your fork (git push origin <branch-name>) and issue a pull request.
  • Feel free to use jQuery.

Commit 1

  • When I click the "Set Color" button, it should change the color of the "brush" box to the color I specify in the input field.
  • Use jQuery to select the element and add an event listener

HINT: You will notice that the page refreshes whenever you click the button. You need to prevent this from happening using a method you have not used before. Google "javascript event prevent default". You can also reference this portion of the Events & Callbacks lesson plan.

Commit 2

  • The same thing should happen when I press the enter key from inside the input field

Commit 3

  • Create 20 divs of the "square" class and append them to the body
    • Hint: use .append()

Commit 4

  • Add functionality so that when I click on each "square", it changes the color of that individual square to "green"
    • Hint: either add the event listener while creating the squares, or listen for events on the body element

Commit 5

  • Modify your code so that when I click on each "square", it changes to the color I set using my input instead of "green" every time.

Commit 6

  • Modify the CSS so that the "square" class has a height and width of 10px and a margin of 0.
  • Modify your code so that you are creating 8000 divs instead of 20.
  • Change the event that changes your box colors from 'click' to 'mouseover'
  • Paint a picture!

Bonus

  • Add a color swatch. You should have 3 boxes with the most recent 3 colors used. When you click on each of those boxes, it should set the current brush color back to that color.
