Create a

JavaScript

function named

display_data

that has two parameters. The first

parameter will be a

String

containing a JSON blob like the function in part 1 returns. The

second parameter will be a boolean.

Start by using the JSON library to convert the first parameter into a usable JavaScript Object.

Next get the HTML element whose

id

is

"data". This HTML element is a

div.

If the second parameter is equal to

true

​, write the value associated with the Object's

"total"

key into the

div

. If the second parameter is equal to

false

, write the value associated with the

Object's

"average"

key into the

div

Examples are also not possible for this problem. Sorry, again!

After completing this part of the lab exam you should download the repl as a ZIP file and submit

Javascripts:

function display_data(id, type) {

document.getElementById(id).innerText = type ? "total" : "average";

}

Sample program to test:

key.js

function display_data(id, type) {

document.getElementById(id).innerText = type ? "total" : "average";

}

window.onload = () => {

display_data("divTag", true)

}

HTML:

<!DOCTYPE html>

<html>

<head>

<meta charset="utf-8">

<meta http-equiv="X-UA-Compatible" content="IE=edge">

<title>Array</title>

<meta name="viewport" content="width=device-width, initial-scale=1">

<script src="key.js"></script>
