Exercises

Instructions:

• For each exercise, start by opening the index.html file for that challenge in your browser. (You can do this from inside Sublime Text by right clicking inside the html file and selecting "Open in Browser").
• To solve the challenge, you'll need to change each base.js file.
• Make sure to open your Chrome Developer Console so that you can check for bugs!
• SOLUTIONS: Solutions are in the solutions branch.

###1. ready

• Challenge: Can you get the page to say "Go!" (without touching the html)?

###2. submit

• Challenge: Can you stop the forms from submitting?
  • Why does one button reload the same page and the other redirect?
  • What is the "?" doing in the URL? Try removing it.
• Bonus: Instead of redirecting to youtube, let's embed the video in our page instead!
  • When the user clicks "submit", dynamically insert the embed code into the page (on youtube, click "share" under the video, then click "embed" and copy the html). HINT: The embed code belongs in your javascript, not your html!

###3. change

• Challenge: Some simple addition! Can you get the total to update whenever you update the numbers?
• Bonus: Add a "reset" button that clears all the inputs.

###4. click

• Challenge: Can you create a list of all the phrases that you click?
• Stretch: In addition to listing the phrase I clicked, can you include a timestamp?

###5. keypress

• Challenge: Stop watch. When the user hits spacebar, record their "start" time. When they hit it again, record their "end" time. Then, calculate the total time, and put it on the page.

###Wrap it up

• Recommended: Can you link all the pages together? Create a navbar at the top of every page, with links to all the other pages.
