We are going to take a trip from the Shire, through Rivendell, across Middle Earth, and into the heart of Mordor itself, Mount Doom. Pack up, because we're going on an adventure.
- Practice using jQuery to manipulate the DOM
- jQuery
- JavaScript
- HTML DOM
-
You will be writing your answers inside the
fellowship.js
file located in tonight'shomework/lotr/scripts/
folder -
While you're working, make sure to open the
index.html
file in your browser to test your work. It is located at:homework/lotr/index.html
- Inside the folder
lotr
folder are anindex.html
file and an astyle.css
sheet that will add some structure and style to your homework. - You will be coding in the
fellowship.js
file. - You will be doing a tiny bit of work in the CSS file once you get to Chapter 9.
- You should not touch the HTML file.
- Open the
fellowship.js
file in your text editor. - Observe the arrays of people and places and the 13 chapters that have been included.
- Note that each chapter has a button in your browser with a click handler attached in the html file, and an associated javascript function in app.js.
- Your job is to fill in the code inside the JS functions to get the application working as intended.
🐘 Remember that you can check your DOM tree in the Elements tab in the Chrome Console.
Tackle tonight's homework one function at a time in order from start to finish.
-
When you begin, write a console.log inside of the function that you are working on to check that the event listener works when you click the associated button.
-
Write the correct DOM manipulatory code inside the function and check that it works.
NOTE: Each function depends on the previous ones, so make sure your function works before moving on to the next one!
- Every time you refresh the browser, you will have to click the buttons one by one in order from the beginning to operate your application. (If really don't want the popups after you've completed a step, you can check to disable each popup and speed up the process of debugging).
Commit your work after each function is complete and working properly
If you need help remember all of the jQuery DOM commands, check out the jQuery Cheatsheet
Provided below are just some screenshots showing you what your index.html
should look like for some of the early chapters so you can be sure you're on the right track!
- All your work in the
fellowship.js
file
Your JavaScript files MUST run without syntax errors. If there are errors you can't solve, comment them out and leave a comment above explaining what is wrong.
