AJAX and Callbacks Lab

Objectives

• Use Ajax's get method
• Use the success callback
• Use the error callback
• Read the API documentation

Introduction

Let's put our new Ajax skills to work by making a GitHub repository search client. This lab will test your ability to use jQuery's $.get function with callbacks and give you some more practice reading API documentation.

All of the HTML and JavaScript files have been provided. The file index.html has a basic two-column structure, and you'll add your JavaScript code to index.js. Don't forget to run the tests, and be sure to load your page up in the browser to make sure everything's working!

Instructions

We're making a GitHub repository search client. It should take a user's search terms, query the GitHub search API for repositories, and display the results in the left-hand column. The user can then click various links in each repository to get more detailed information in the right-hand column.

1. Create a "Search Repositories" link that calls a searchRepositories function on click, takes the value of a searchTerms text input, and queries the GitHub repository search API.
2. Display the collection of repositories inside the results div. Include repository name, description, and a link to the HTML URL. Also include repository owner login, repository owner avatar as an image, and a link to the owner's profile page. Hint: Pay close attention to the structure of the search results!
3. Add a "Show Commits" link to each repository result that will call a showCommits function that gets the repository's commits from the GitHub API and display them in the details div. For each commit, list the SHA, the author, the author's login, and the author's avatar as an image.
4. Handle errors on each API call. If $.get fails, call a function displayError and display "I'm sorry, there's been an error. Please try again." in the errors div. Hint: You can test your error callbacks by turning off Wi-Fi or temporarily changing the URL you use in the $.get request.
