Generating a random lottery number can be easily done in Javascript. The following code generates nine two-digit random numbers and displays them in a paragraph. To change the number of digits simply change the value of “numbers” variable at the head of the javascript code. Whenever the page is loaded a new number will be generated.
Here is the html:
<!doctype html> <html lang="en"> <head> <meta charset="utf-8"> <title>Random lottery number </title> </head> <body> <p>Winning Numbers: <span id="result"></span></p> <script src="random.js"></script> </body> </html>
The javascript:
function displayNumbers() {
'use strict';
var numbers = 9; // replace 9 with your desire number
var r= '';
for (var i = 0; i < numbers; i++) {
r += parseInt((Math.random() * 100), 10) + ' ';
}
var result= document.getElementById('result');
if (result.textContent !== undefined) {
result.textContent = r;
} else {
result.innerText = r;
}
}
window.onload = displayNumbers;
