I'm having trouble making the questions random. If you could help, it would be awesome!
(If you have spear time; I've been given the task to mark correct answer with a green feather and wrong answers with red feather, for instance, if you get 3 correct and 2 wrong. It will show 3 green feathers and 2 red feathers as score.) Thank you!
<script type="text/javascript">
var questions = [
['firstcar.gif','0'],
['secondcar.gif','1'],
['thirdcar.gif','2'],
['firstcar.gif','0'],
['secondcar.gif','1'],
['thirdcar.gif','2'] // Note: no comma after last entry
];
var qNo = 0;
var correct = 0;
var cnt = 0;
function NextQuestion(response) {
if ((qNo < questions.length) && (response == questions[qNo][1])) {
correct++;
}
document.getElementById('score').innerHTML = 'Correct ' + correct + ' of 6 questions';
qNo++;
if (qNo < questions.length) {
document.getElementById('Pic').src = questions[qNo][0];
cnt++;
}else{
alert('Quiz is done. You got ' + correct + ' points!');
}
}
onload = function() {
document.getElementById('Pic').src = questions[0][0];
}

Well, your questions are in an array. So what you should be researching is how to randomise the order of an array.
questions.sort(function() { return Math.floor(Math.random() * 2); });

template strings ${variable}
In JavaScript you can use template strings
The usage is
` ${variable} `
document.getElementById('btn').addEventListener('click', press)
function press() {
for (var i = 0; i < 4; i++) {
if (!document.getElementById(`ip${i}`).value) {
alert("error");
break;
}
}
}
<input id="ip0"/>
<input id="ip1"/>
<input id="ip2"/>
<input id="ip3"/>
<button id="btn">Click</button>

I have a slot machine that I made recently, but I would like to make it look a bit better.
https://codesandbox.io/s/slot-machine-xip7x?file=/index.html:0-1480 (I apologize, I was having issues copy and pasting the code into a code sample :( I am new to this site.)
Here is the result of that code: https://xip7x.csb.app/
Every time you roll, a bullet point show up at the left side of your screen with the result in the middle. When you roll multiple times, the new results are just added to what is already there. Can anybody make it so that there are no bullet points, and every time you roll it replaces your previous roll and only shows the new one, so you only have one roll on the page at all times. I am new to coding and would love to complete this project. If anybody could help me out and explain what they did, I would love that. Thanks!
is this what u want?
var firstx = ["X", "O", "L", "L"];
var secondx = ["X", "O", "L", "L"];
var thirdx = ["X", "O", "L", "L"];
function randIndex() {
var randIndex1 = Math.floor(Math.random() * 4);
var randIndex2 = Math.floor(Math.random() * 4);
var randIndex3 = Math.floor(Math.random() * 4);
var first = firstx[randIndex1];
var second = secondx[randIndex2];
var third = thirdx[randIndex3];
var btn = document.getElementById("btn");
var sent = document.getElementById("sent");
var result = first + " " + second + " " + third;
if (result == "X X X") {
alert("CONGRATULATIONS! YOU WIN!");
}
sent.innerHTML ="<li>" + result + "</li>";
btn.innerText = "Roll Again";

I am trying to make this script auto change between the four after 30 seconds, I am not to good at jquery but I wanted to give it a try. This is all on a .php page I am using to bring up the javascript from my other folders.
<div id="subnavi">
<div id="subnavi-user">
<div style="margin-top:7px"><b>Fact:</b> <script language="JavaScript">
var r_text = new Array ();
r_text[0] = "{hotelName} was founded in 2011 by Kyle";
r_text[1] = "{hotelName} strives to remain as professional as possible.";
r_text[2] = "{hotelName} will only keep on growing if you vote daily!";
r_text[3] = "Purchasing VIP in the forums helps with the monthly server costs.";
r_text[4] = "{hotelName} Is a new and developing RP!";
window.setInterval(function(){
var i = Math.floor(4 * Math.random())
document.write(r_text[i]);
var random = r_text[1];
}, 5000);
</script>
</div>

I am not sure if this is what you are looking for but here it is:
This script will run every time you reload the page. IF you need it to work in a different way just update your question and i will update my script.
<script src="//code.jquery.com/jquery-1.11.0.min.js"></script>
<script>
var r_text = new Array();
r_text[0] = "Hello";
r_text[1] = "Test";
r_text[2] = "We are the lions";
r_text[3] = "Fight";
r_text[4] = "Switch!";
window.setInterval(function(){
var i = Math.floor(5 * Math.random())
var random = r_text[i];
$('#r_text').html(random);
}, 5000); // you can change the interval here
The HTML part
<div id="r_text"></div>
Check this out here
Update
Change your Math.floor to count to 5 because your array has 5 elements in it not 4
Update 2 Your file should look like something like this
<!Document html>
<head>
<script src="//code.jquery.com/jquery-1.11.0.min.js"></script>
<script>
var r_text = new Array();
r_text[0] = "Hello";
r_text[1] = "Test";
r_text[2] = "We are the lions";
r_text[3] = "Fight";
r_text[4] = "Switch!";
window.setInterval(function(){
var i = Math.floor(5 * Math.random())
var random = r_text[i];
$('#r_text').html(random);
}, 5000); // you can change the interval here
</script>
</head>
<body>
//Add your html/php code here and pick a place where to show the response of your function. Something like <div id="r_text"></div>
</body>

<script type='text/javascript'>
function replaceNewlines(e) {
var element = document.getElementById('myTextarea');
if (e.keyCode == 13) {
element.value = element.value.replace("\r", "<br />");
element.value += "___NEWLINE___\n";
element.value = element.value.replace("___NEWLINE___\n", "<br />");
}
}
</script>
This code works fine but when I press enter, <br /> appears in the textarea and I don't want to appear this in my textarea.
Can somebody help me?
So, how about replacing <br /> with a new line?
<script type='text/javascript'>
function replaceNewlines(e) {
var element = document.getElementById('myTextarea');
element.value = element.value.replace(/<br\s*\/?>/g, '\n');
}
</script>

<script>
var dot = ".";
var counter = 0;
var message = "Loading Page";
function writeLoadingMessage(){
if (counter > 6) return;
setTimeout('writeMessage();',1000);
}
function writeMessage(){
document.getElementById('loadingMessageSpan').innerHTML = message + dot;
message += dot
counter++
writeLoadingMessage();
}
</script>
<BODY>
<span style="font-weight:bold;" id="loadingMessageSpan"></span>
<SCRIPT>writeLoadingMessage();</SCRIPT>
</BODY>
(function(){var i=6,a=setInterval(function(){document.getElementById('loadingMessageSpan').innerHTML+=".";!i--&&clearInterval(a);},1E3)})()
You will need to have Loading already in your span tag. As a note it is pointless to worry about getting it this small though. Also, the page will will have to be already loaded.
If you want it shorter: http://jsfiddle.net/pimvdb/wBFSy/.
<script>
var counter = 0;
function writeMessage() {
document.getElementById('loadingMessageSpan').innerHTML += ".";
if(++counter < 7) {
setTimeout(writeMessage, 1000);
}
}
window.onload = writeMessage;
</script>
<body>
<span style="font-weight:bold;" id="loadingMessageSpan">Loading Page</span>
</body>
Minifying also helps :)
var a=0;function b(){document.getElementById("loadingMessageSpan").innerHTML+=".";++a<7&&setTimeout(b,1E3)}window.onload=b
1) User setInterval instead.
2) Just set the message once and append . to end
3) Put all the js at the bottom
<body>
<span style="font-weight:bold;" id="loadingMessageSpan">Loading Page</span>
<script type="text/javascript">
var counter = 0;
var id = setInterval(function(){
document.getElementById('loadingMessageSpan').innerHTML += ".";
if(++counter>6) {
clearInterval(id);
}
}, 1000);
</script>
</body>
If you really want it short you can go this route:
<BODY>
<span style="font-weight:bold;" id="loadingMessageSpan">Loading Page</span>
<script>
var counter = 0;
var interval = setInterval(function(){
document.getElementById('loadingMessageSpan').innerHTML += ".";
if(++counter > 6)
clearInterval(interval);
},1000)
</script>
</BODY>
