Schoology Assignment Spam Bot

/*************************************************************************
This script spams the comments of a schoology assignment. It's very fun (;
*************************************************************************/

var speed = 5; //How long to wait between posting (in seconds). Change this to however long you want the delay to be.
var text = "Example"; //Change the text in-between the quotes to change what the bot says


//Don't touch anything underneath this line
var a = speed * 1000; //Convert seconds to milliseconds (JavaScript uses milliseconds instead of seconds to determine time)
function spam() {
document.getElementById('edit-comment').value = text; //Change the comment box to the desired text
document.getElementById('edit-submit').disabled = null; //Make schoology think the "submit" button isn't disabled; also meaning the user typed something
document.getElementById('edit-submit').click(); //Click the submit button
}
setInterval(function(){spam();}, a); //Repeat the spam function
