WEB222 Assignment4–DOM Manipulation

Grade value: 5% of your final course grade

Objective

Practise DOM/JavaScript coding, dynamically adding image and populating HTML table using DOM (rather than innerHTML property), and updating the text in HTML element using the innerHTML property.

Specifications

To begin, download assign4-template.zip file from My.Seneca/Blackboardand unpack the zip file. In this assignment, you’ll build up a front-end web app which queries data from a given array of Country objects, named countries, and show the results on a web page using HTML DOM API.The array of Country objects is provided in the js/a4-country-data.js file and all countries’ flag images are stored under the flags folder. And your tasks are to update JavaScript code in themyscript.js file according to the instructions below.

Open the assignment4.html file in a browser, a 2-level menu will show up on the page,

Your tasks are that when the menu items are clicked, appropriate country data should be populated into the HTML table as specified.

BASIC REQUIREMENTS

You should not change the given files assignment4.html, a4-country-data.js or image files under flags folder. The myscript.js and honesty.html are the two files that you are allowed to update. Note: you should create event handlers to the menu items (the assignment4.html document’s unorder list <li id=”menu_??”> items) using JavaScript code inside the myscript.js file. When one of these items is clicked, a corresponding function should be called to change the subtitle and populate the country table.

You must not use the DOM/NodeinnerHTML property to populate HTML
tables, including adding images. However, using innerHTML property to update the text of the “subtitle” (<h4 id=”subtitle”>List of Countries and Dependencies</h4>) on the page is appropriate.

When running your web app on a browser, no errors should occur on the browser web console.
