Hi, Trying to learn JavaScript. I was playing with the code and I'm a little confused about something seemingly simple. In the code below (from chap 5 random.js), when I comment out the line, var output = document.getElementById('output');, and save the file. When I refresh the browser window it still generates a random number. If I type "output" in the console I get <span id="output">. If I type "output.textContent" I get the random number. It seems as if this variable is not even needed. What is the reason for this?
function showNumbers() {
'use strict';
// Variable to store the lucky numbers:
var numbers = '';
// Get the numbers:
for (var i = 0; i < 6; i++) {
numbers += parseInt((Math.random() * 100), 10) + ' ';
}
// Show the numbers:
var output = document.getElementById('output');
if (output.textContent !== undefined) {
output.textContent = numbers;
} else {
output.innerText = numbers;
}
} // End of showNumbers() function.
// Initial setup:
window.onload = showNumbers;
Thanks, Jeff
