Exercise 1.1 - Buttons and Inputs

c) Calculate the sum

This is the console. All output created with writeLog() is shown here.

Please type a number in each input field and press "Add". I will print the sum of both to the console.

script.js

This is the JavaScript code behind the above application.

/* global writeLog, getInput */
log("Solution for exercise 1.1 c)");
function add() {
    // Get the values from both input fields
    var numberA = getInput("theNumberA");
    var numberB = getInput("theNumberB");
    writeLog("I will perform this calculation: " + numberA + " + " + numberB);
    var sum = parseFloat(numberA) + parseFloat(numberB);
    writeLog("The result is: " + sum);

	/* global writeLog, getInput */
	log("Solution for exercise 1.1 c)");

	function add() {
	// Get the values from both input fields
	var numberA = getInput("theNumberA");
	var numberB = getInput("theNumberB");

	writeLog("I will perform this calculation: " + numberA + " + " + numberB);

	var sum = parseFloat(numberA) + parseFloat(numberB);
	writeLog("The result is: " + sum);
	}
