I'm doing an assignment for a class, where it says I need to modify jquery.altrow.js to create a plugin that uses the getElementsByTagName method to get all of an element’s “tr” child elements. They provide the following HTML and JavaScript:
<!DOCTYPE html><html><head> <meta charset="UTF-8"> <title>Alternating Row Plugin</title> <link rel="stylesheet" href="altrow.css"> <script src="http://code.jquery.com/jquery-2.1.4.min.js"></script> <script src="jquery.altrow.js"></script> <script src="altrow.js"></script></head><body> <main> <h1>Important People in Computer Science</h1> <table id="important"> <tr> <th>First Name</th><th>Last Name</th><th>Date of Birth</th><th>Accomplishment</th> </tr> <tr> <td>Charles</td><td>Babbage</td><td>12/26/1791</td> <td>Originated the concept of a programmable computer, invented the first mechanical computer.</td> </tr> <tr> <td>Ada</td><td>Lovelace</td><td>12/10/1815</td> <td>First computer programmer.
