How can I use Javascript to apply CSS to multiple buttons when one is clicked?

I have a survey page where users can click buttons on a scale from 1-5 to say how their experience was. Currently, clicking one button (say 3 out of 5) will change the background color of that one button to indicate it was clicked. What is the best way to approach this if I want to have all buttons have the updated background color up to whatever was clicked? Example: If they click "3" out of 5 then it would highlight buttons 1, 2, and 3.
Any help appreciated.

e.preventDefault();
let checkOne = false;
let checkTwo = false;
let checkThree = false;
let checkFour = false;
let checkFive = false;
CSS:
#wr-1:checked+label,
#application-rating-1:checked+label,
#goals-rating-1:checked+label,
#refer-rating-1:checked+label,
#sat-1:checked+label {
background: url('/wp-content/themes/theme52950/images/reviews-faces/1-hover.png');
height: 55px;
width: 109px;
display: inline-block;
padding: 0 0 0 0px;
background-repeat: no-repeat;
}

Native checkboxes can't be styled, so you can't easily add a checked appearance to an unchecked checkbox. You can however hide the native appearance, and do some CSS trickery to show a checkbox with round border.
With this you can use jQuery (or native JS) to add a checked appearance to round borders, here to all checkboxes preceding the current one:
$(function() {
$('.form-control input[type="radio"]').click(function(e) {
let $el = $(this);
console.log('clear all highlights');
$el.parent().find('input[type="radio"]').css({ backgroundColor: '#FF572233' });
let id = $el.attr('id');
do {
if(id) {
console.log('highlight', id);
$el.css({ backgroundColor: '#993333' });
}
$el = $el.prev().prev();
id = $el.attr('id');
} while(id);
});
});
.form-control input[type="radio"] {
height: 0.9rem;
width: 0.9rem;
margin-right: 0.5rem;
/* The native appearance is hidden */
appearance: none;
-webkit-appearance: none;
/* For a circular appearance we need a border-radius. */
border-radius: 50%;
/* The background will be the radio dot's color. */
background: #FF572233;
/* The border will be the spacing between the dot and the outer circle */
border: 3px solid #FFF;
/* And by creating a box-shadow with no offset and no blur, we have an outer circle */
box-shadow: 0 0 0 1px #FF5722;
}
.form-control input[type="radio"]:checked {
background: #993333;
}
.send-btn {
margin-top: 15px;
}
.as-console-wrapper { max-height: 85px !important; }

Issues with swipe and/or animate in JS

What it is:
I am having an issue with my swipeable form. It uses a vanilla JS method to achieve swipe recognition and .animate to cycle through each part of the form.
My problem:
When too many swipes are performed in succession or too many next buttons are clicked in succession, the .animate seems to fail and they start to pile up in the center of the visible area.
Things I've tried:
I've tried stopPropagation() and setTimeout(), but neither have helped. I've also tried removing the listeners at the start of their function and adding them back at the end of the nextPrev() function, which also didn't correct the issue.
I'm not sure where exactly it is going wrong and therefore don't know how to troubleshoot this. I've tried different things at various stages and nothing seems to correct this issue. I am looking for a way to prevent this from happening.
I apologize for not presenting an MCVE, I left everything in intentionally so someone could experience cycling through the form and reproduce the issue.

update: ariel's solution is a good one, though it did not fix my problem. This sort of flagging is important, and my code should've already been equipped with it. I am still experiencing issues, though I found something promising here: https://css-tricks.com/full-jquery-animations/
Though it does not fix my problem completely, it is getting very close to a solution and I will update when I have one.

You need to use a flag to prevent the event firing when the animation is happening:
var isSwiping = false;
function startSwipe() {
if (isSwiping) {
return false;
} else {
isSwiping = true;
$("button#back, button#next").attr("disabled", true);
return true;
}
}
function endSwipe() {
$("button#back, button#next").removeAttr("disabled");
isSwiping = false;
}
function nextPrev(n) {
if (startSwipe()) {
...
// Inside animate callback:
endSwipe();
...
}
...
document.getElementById('form').addEventListener('touchstart', handleTouchStart, false);
document.getElementById('form').addEventListener('touchmove', handleTouchMove, false);
document.getElementById('form').addEventListener('touchend', handleTouchEnd, false);
...
function handleTouchStart(evt) {
if (startSwipe()) {
...
}
};
function handleTouchMove(evt) {
if (isSwiping) {
...
}
};
function handleTouchEnd(evt) {
endSwipe();
};

You can add an eventListener for the click event. To re-activate a button set disabled to false.
document.addEventListener("DOMContentLoaded", () => {
let inputs = document.querySelectorAll(".radioBtn");
inputs.forEach(input => input.addEventListener("click", () => {document.querySelector('.activeBtn').disabled = false;}))
});
.blockRez{

Javascript border colour not changing on radio button click

Im sorry to open a question, which I am sure many will consider very basic but I don't really know javascript and am learning as my application grows
I have the following
When radio button is clicked I would like the div with class="teams" to change border colour to red.
I came up with this code
<label><input type="radio" onclick="return border()" name="picks['.$x.']" id="one" value="'.$row['team1'].'"><span>'.$team1.'</span></label><br />
<label><input type="radio" onclick=" return border()" name="picks['.$x.']" id="two" value="'.$row['team2'].'"><span>'.$team2.'</span></label><br />
<label><input type="radio" onclick="return border()" name="picks['.$x.']" id="three" value="draw"><span>Draw</span></label><br />
</center>';
function border(){
if(document.getElementById("one").checked){
document.getElementById("teams").style.borderColor="red"
}
else if( document.getElementById("two").checked){
document.getElementById("teams").style.borderColor="red"
}
}
echo'<div class="teams">';
echo'<img src="images/teams/'.$src1.'.png" id="t1" />';
echo'<img src="images/teams/'.$src2.'.png" id="t2" />';
echo'</div>';
Clearly I am doing something wrong. Any help will be greatly appreciated
Following is the error thrown.

teams is a class attribute and not ID.
Change getElementById("teams") to getElementsByClassName("teams")
Note that getElementsByClassName("teams") returns an array of matched elements; so use a loop to set the value of each or just use getElementsByClassName("teams")[0].style.borderColor
function border() {
var el = document.getElementsByClassName("teams")[0];
if (document.getElementById("one").checked || document.getElementById("two").checked) {
el.style.borderColor = "red";
el.style.borderStyle = "solid";
}
}

Try onclick="border(this.id)"
<labe><input type="radio" onclick="border(this.id)" name="picks['.$x.']" id="one" value="'.$row['team1'].'"><span>'.$team1.'</span></label><br />
<label><input type="radio" onclick=" border(this.id)" name="picks['.$x.']" id="two" value="'.$row['team2'].'"><span>'.$team2.'</span></label><br />
function border(id){
if(document.getElementById(id).checked){
document.getElementsByClassName('teams')[0].style.borderColor="red"
}
}
Working demo

In your code teams is a class name and not id.
echo'<div class="teams">';
Either you change it to id:
echo'<div id="teams">';
Or use getElementsByClassName("teams"), it will give you NodeList
document.getElementsByClassName("teams")[0].style.borderColor="red";
Apart from this, you could possibly try this solution just using css pseudo:
input[type=radio].check {
display: none;
}
input[type=radio].check + label.check {
border: 1px solid grey;
padding: 5px 7px;
cursor: pointer;
width: 150px;
display: block;
text-align: center;
margin-bottom: 2px;
}
input[type=radio].check:checked + label.check {
background: red;
}
<input type='radio' name='team' value='Team 1' class='check' id='check1' />
<label for='check1' class='check'>Team 1</label>
<input type='radio' name='team' value='Team2' class='check' id='check2' />
<label for='check2' class='check'>Team 2</label>
<input type='radio' name='team' value='Draw' class='check' id='check3' />
<label for='check3' class='check'>Draw</label>

Just a little tip I would try and get away from using the onclick events and move towards external javascript.
I've created an example of something you could try.
$(':radio').change(function ()
{
if ($(this).val() == "team1")
{
$(".row").css("border-color", "blue");
}
else if ($(this).val() == "team2")
{
$(".row").css("border-color", "red");
}
});
div.row {
border: 2px solid black;
height: 200px;
width:200px;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<div class="row">
</div>
<label for="team1">1</label>
<input id="team1" type="radio" name="team1" value="team1">
<label for="team2">2</label>
<input id="team2" type="radio" name="team2" value="team2">

Working Example

If you disable, user can't change his choice after first selection.
Here is a radio button behavior for checkbox.
$("input[type=checkbox]").on('click', function() {
$("input[type=checkbox]").not(this).attr('checked', false);
});
http://jsfiddle.net/BxF4Y/
But to doing that, the best way is to use radio buttons.

Browsing the source code of that page reveals the jQuery they used to achieve that effect. You should just be able to change the checkboxLimit to 1.
<script type="text/javascript">
jQuery(document).ready(function($) {
$.fn.checkboxLimit = function(n) {
var checkboxes = this;
this.toggleDisable = function() {
// if we have reached or exceeded the limit, disable all other checkboxes
if(this.filter(':checked').length >= n) {
var unchecked = this.not(':checked');
unchecked.prop('disabled', true);
}
// if we are below the limit, make sure all checkboxes are available
else {
this.prop('disabled', false);
}
}
// when form is rendered, toggle disable
checkboxes.bind('gform_post_render', checkboxes.toggleDisable());
// when checkbox is clicked, toggle disable
checkboxes.click(function(event) {
checkboxes.toggleDisable();
// if we are equal to or below the limit, the field should be checked
return checkboxes.filter(':checked').length <= n;
});
}
$("#field_11_1 .gfield_checkbox input:checkbox").checkboxLimit(3);
});
</script>

Yes, this is an old thread, however there is no real conclusion here. I have included a fiddle with my version of how check-boxes should work should you wish to limit the number of boxes checked by the user.
