How do I make it so only one element is shown at once?

When the box is clicked on the insides for each of the boxes are shown, I only want one to show up at a time.
function select() {
const outside = document.querySelectorAll('.box')
const insides = document.querySelectorAll('.insides')
insides.forEach(insides => {
outside.forEach(box => {
box.addEventListener('mouseenter', (e) => {
box.setAttribute("id", "selected")
box.addEventListener('click', (e) => {
box.classList.add('hover')
if (document.getElementById('selected')) {
insides.classList.add('insidesHover')
}
})
})
box.addEventListener('mouseleave', (e) => {
box.classList.remove('hover')
box.setAttribute('id', 'testBox')
insides.classList.remove('insidesHover')
})
})
})
}
function newOption() {
var optionRow = document.createElement("div");
optionRow.setAttribute("class", "answers");
optionRow.setAttribute("id", "optionRow");
var option = document.createElement("input");
option.setAttribute("type", "radio");
option.setAttribute("name", "options");
option.setAttribute("id", "options");
var optionBox = document.createElement("div");
optionBox.setAttribute("class", "answerContainer")
optionBox.setAttribute("id", "optionBox")
var text = document.createElement("input");
text.setAttribute("type", "text");
text.setAttribute("name", "option");
text.setAttribute("id", "option");
text.setAttribute("placeholder", "Enter Option");
optionBox.append(optionRow);
optionRow.append(option);
optionRow.append(text);
document.getElementById("selected").append(optionRow);
array()
}
.testContainer {
width: 50%;
margin-left: 25%;
margin-top: 1%;
padding: 1%;
background-color: #333;
height: auto;
color: white;
}
.box {
background-color: white;
color: black;
padding: 25px;
border: 5px blue solid;
}
.hover {
border: #780119 5px solid;
}
.insides {
display: none;
}
.insidesHover {
display: flex;
}
.buttons {
display: none;
}
.buttonsHover {
display: flex;
height: 25px;
width: 25px;
border: 1px solid black;
border-radius: 100%;
}
<div class="testContainer">
<div class="box">
<div class="insides" id="testBox">
<input type="text" class="insidesHover">
<button onclick="newOption()" class="buttonsHover"> </button>
</div>
</div>
</div>
<div class="testContainer">
<div class="box">
<div class="insides" id="testBox">
<input type="text" class="insidesHover">
<button onclick="newOption()" class="buttonsHover"> </button>

</div>
</div>
<div class="testContainer">
<div class="box">
<div class="insides" id="testBox">
<input type="text" class="insidesHover">
<button onclick="newOption()" class="buttonsHover"> </button>
</div>
</div>
</div>
So the problem I am having is that I want to use a querySelectorAll() for the class of .box, which on click changes the outline to show it is being selected. Which is something that is fully functional and works. However, I also want it to show the inside pieces on click as well but only for one box at a time, which on the event listener of leave will disappear again. Once the inside of adding new options goes away, I need the options that were put in to stay. I have tried putting everything in one div class where the opacity is set to 0, but it makes it so the new options don't stay visible. I have also tried rearranging the variables so that the insides are affected first, which had no effect on the actual functionality. I believe the true issue lies in the fact that when the id, selected, is active it triggers all boxes to be active instead of individual ones. I am not entirely sure how to go about rectifying this issue and would like some advice on moving forward. If you have any questions or if something needs clarification please let me know! Thank you for your time and wish you all a good day!

After auto scroll to bottom of div, enable user to scroll back up?

There are a large number of this question floating around this site. None of them seem to help me though. I am trying to code a text based browser game using javascript and jQuery, as a base to build my knowledge of coding.
I have a javascript code:
window.setInterval(function(e) { //This function is the only way to get the scroll to bottom to work, for me.
e = document.getElementById('console'); //'console' is the area that outputs the system text, after a user answers questions.
e.scrollTop = e.scrollHeight - e.clientHeight; //It works without the '- e.clientHeight', but I read that this is proper.
});
For the scroll to bottom function, this works very well, but how in the world do I allow the user to scroll up... to review what has transpired?
I haven't found a question asked in this fashion, so I don't believe it is a duplicate. If so, I guess I'll keep searching.
-Edit-
Okay... I guess my description wasn't descriptive enough, so let me try to fix that.
Here is a snipit of the first bit of my code (I know it isn't set up the best right now, but that is why I'm learning):
Javascript/JQuery
window.setInterval(function(e) { //'#console' scrolls to bottom <-- how do I let the user scroll up to review?
e = document.getElementById('console');
e.scrollTop = e.scrollHeight - e.clientHeight;
});
onkeyup = (function(e) { //On <enter> erase data in the ("input")
if (e.keyCode == 13) {
$("input").val("");
e.preventDefault();
return false;
}
});
$(document).ready(function() {
$("#console").fadeIn(3000); //A console to output answers and scenarios to
$("form").submit(function() { //User input
var input = $("#command_line").val(); //A nifty box to put your answers in
var check = false;
function check() { //If you don't follow directions this happens
check = true;
}
//startup
var yes = false;
var no = false;
currentarea = "Start";
function start() {
while (yes != true && no != true && currentarea == "Start") {
if (input == "yes") {
yes = true;
$("<p>Great! What is your gender? Type <u><b>m</b></u> for Male or <u><b>f</b></u> for Female.</p>").hide().insertBefore("#placeholder").fadeIn(1000);
clothes = s_clths;
document.getElementById("clothes").innerHTML = clothes;
currentarea = "Gender Assignment";
check();
return currentarea;
}
}
start();
});
So, basically, after getting the scroll to bottom working, I noticed users might want to scroll up to see what previous statements said. Right now, they cannot scroll up. If I need to make another code all together that is okay, but I cannot find one that will work for me. I've tried every suggestion I could find from all the relative postings, with no success. I have been at this for about twelve hours now, and can't figure it out by myself.

The answer to my question was:
$("#console").animate({ scrollTop: "999999999px" }, 'slow'); //Scroll the console to the bottom.

Using jQuery to alternate between classes upon click event

I'm feeling awfully silly here - I can't get a simple class switching statement to work in jQuery! I can only sit in frustration as for the last 45 minutes, I've searched Stack Overflow questions and answers, to no avail.
My goal is, upon clicking an item with the colorClick id (already containing a default class of "white"), to rotate that item between being assigned the class green, yellow, orange, red, and back to white again (ad infinitum).
The CSS is simple - each class simply corresponds to a different background color.
The HTML is simple - a div tag with two CSS classes (one static, one to be changed by jQuery).
The jQuery is simple - read the class on the clicked item, and change it.
And now, you understand what vexes me. Here's what I'm working with so far:
$("#colorClick").click(function () {
if ($(this).hasClass('white')) {
$(this).removeClass("white").addClass("green");
} else if ($(this).hasClass('green')) {
$(this).removeClass('green').addClass('yellow');
} else if ($(this).hasClass('yellow')) {
$(this).removeClass('yellow').addClass('orange');
} else if ($(this).hasClass('orange')) {
$(this).removeClass('orange').addClass('red');
} else if ($(this).hasClass('red')) {
$(this).removeClass('red').addClass('white');
});
.toDoItem {
text-align: left;
padding: 3px;
margin-bottom: 5px;
border: 1px solid;
border-color: #e8e7e7;
}
.white {
background-color: #ffffff;
}
.green {
background-color: #b2d8b2;
}
.yellow {
background-color: #ffffb2;
}
.orange {
background-color: #ffe4b2;
}
.red {
background-color: #ffb2b2;
}
<div class="toDoItem white" id="colorClick">To-do list item</div>
<div class="toDoItem white" id="colorClick">To-do list item</div>
<div class="toDoItem white" id="colorClick">To-do list item</div>
Link to the fiddle:
http://jsfiddle.net/andrewcbailey89/4Lbm99v0/2/

First things first, when making a list, you should use the correct list elements. Your "To Do" list fits the definition of a description list (<dl>) so you should use that instead of <div> elements.
You can save a lot of lines of code by getting rid of the classes and creating an array of colors. Make sure that the colors are in the same order that you want them to be shown. We will use this array to set the background color based on an incremented counter.
var colors = ['#b2d8b2', '#ffffb2', '#ffe4b2', '#ffb2b2', '#fff'];
You can also greatly simplify your script by using a "factory" function which defines a scope and builds an event listener function, which it returns. This creates a "safe" scope for each listener function to reside in that we can define variables which will store information between events.
In the following snippet, we define a count variable that we increment on each click. We use the incremented variables remainder when dividing by the length of the color array using the modulo operator %. If the number is smaller than the length of the array, it will return the number, otherwise it will return the remainder when dividing by the length of the array, allowing us to loop through continuously.
function todoItemListener() {
var count = 0;
return function () {
$(this).css({ 'background-color': colors[count++ % colors.length] });
}
}
Then instead of assigning the function declaration as normal (without the parenthesis), we assign the result of the factory function, simply append the parenthesis and the function will execute and return the resulting listener function. This allows us to add as many listener functions as we want, so if you're adding new todo list items, we can simply build another listener function.
$('.todo-list dd').each(function () {
$(this).on('click', todoItemListener());
});
$('.add-item').on('click', function () {
var list = this.parentNode.parentNode;
$('<dd>To-do list item</dd>').appendTo(list).on('click', todoItemListener());
});
This method also allows you to easily change the array of colors at will. So say if an option is selected somewhere on the page, another color could become available, or not available.
Also, for some extra UX goodness, I added CSS to stop selection of the text on click (that can get annoying) and to change the cursor to a pointer to give it a more actionable feel.
Here is the full demo, I've included multiple to-do lists to show that it can be done.
var colors = ['#b2d8b2', '#ffffb2', '#ffe4b2', '#ffb2b2', '#fff'];
function todoItemListener() {
var count = 0;
return function () {
$(this).css({ 'background-color': colors[count++ % colors.length] });
}
}
$('.todo-list dd').each(function () {
$(this).on('click', todoItemListener());
});
$('.add-item').on('click', function () {
var list = this.parentNode.parentNode;
$('<dd>To-do list item</dd>').appendTo(list).on('click', todoItemListener());
});

text-align: left;

You are missing some quotes in a few places, and you didn't close the last if statement.
ex: $(this).hasClass(green) should be $(this).hasClass('green')
Additionally, you should change colorClick to a class rather than an ID, as there are multiple of these elements.
I also changed all of your quotes to single quotes for consistency's sake.
Here is a working snippet:
$(".colorClick").click(function () {
if ($(this).hasClass('white')) {
$(this).removeClass('white').addClass('green');
} else if ($(this).hasClass('green')) {
$(this).removeClass('green').addClass('yellow');
} else if ($(this).hasClass('yellow')) {
$(this).removeClass('yellow').addClass('orange');
} else if ($(this).hasClass('orange')) {
$(this).removeClass('orange').addClass('red');
} else if ($(this).hasClass('red')) {
$(this).removeClass('red').addClass('white');
}
});
.toDoItem {
text-align: left;
padding: 3px;
margin-bottom: 5px;
border: 1px solid;
border-color: #e8e7e7;
}
.white {
background-color: #ffffff;
}
.green {
background-color: #b2d8b2;
}
.yellow {
background-color: #ffffb2;
}
.orange {
background-color: #ffe4b2;
}
.red {
background-color: #ffb2b2;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="colorClick toDoItem white">To-do list item</div>
<div class="colorClick toDoItem white">To-do list item</div>
<div class="colorClick toDoItem white">To-do list item</div>

First you are using same id for multiple elements. id should be unique for each element. You can use toDoItem class instead of colorClick id to bind click event. To get rid of complex if else statement you can put all class in an array in your required sequence. Then on click of toDoItem change class according to the sequence of array. If you reached at the last item of array then go back to first.
var colors = ['white', 'green', 'yellow', 'orange', 'red'];
var total = colors.length-1;
$(".toDoItem").click(function() {
var color = $(this).attr('class').split(' ')[1];
var index = colors.indexOf(color);
index = index==total? 0 : index+1;
$(this).removeClass(color).addClass(colors[index]);
});
.toDoItem {
text-align: left;
padding: 3px;
margin-bottom: 5px;
border: 1px solid;
border-color: #e8e7e7;
}
.white {
background-color: #ffffff;
}
.green {
background-color: #b2d8b2;
}

jQuery slide animate div with toggle button works every other time instead of every time

I'm trying to get a simple side navigation bar which you can hide and unhide with a single button.
So far I have it worknig but only every other click, so click to hide works, then does nothing, next click unhides, nothing etc. Yet I have to button set to an image to change on every click, and that is working.
What I have so far is....
HTML:
<div id="navBar-control">
<a href="#" id="toggle-slide-button">
<img src="http://i.imgur.com/8BMxPsC.png" width="50px" height="50px" />
</a>
</div>
<div id="navBar">
<div class="navBtn navBtnText">
Calculator
</div>
<div class="navBtn navBtnText">
About
</div>
<div class="navBtn navBtnText">
Other Services
</div>
</div>
Script:
var state = false;
$("#toggle-slide-button").click(function () {
if (!state) {
$('#navBar').animate({width: "toggle"}, 1000);
$('#toggle-slide-button img').attr('src', 'http://i.imgur.com/K3MG7gT.png');
state = true;
}
else {
$('#mnavBar').animate({width: "toggle"}, 1000);
$('#toggle-slide-button img').attr('src', 'http://i.imgur.com/8BMxPsC.png');
state = false;
}
});
and if it matters, CSS:
#navBar{
background-color: #660000;
height: 780x;
width: 80px;
}
.navBtn{
background-color: #660000;
color: white;
width: 80px;
height: 70px;
cursor: pointer;
border-bottom: 1px solid rgba(255,255,255,.2);
opacity: 1;
font-size: 12px;
text-align: center;
}
.navBtnText {
line-height: 120px;
vertical-align: bottom;
}
.navBtn:hover{
background-color:#990000;
}
#navBar-control {
width: 50px;
height: 100%;
padding: 0 15px;
background-color: #000;
}
Fiddle of this: http://jsfiddle.net/GUjPA/91/
I have been basing this off this fiddle: http://jsfiddle.net/GUjPA/13/ This has the desired behavior only that it is on the right of the screen instead of the left. The script I'm using is exactly the same, and besides different colours and size of side bar, its essentially exactly the same.

You have a mistake here:
$('#mnavBar').animate({width: "toggle"}, 1000);
must be
$('#navBar').animate({width: "toggle"}, 1000);
http://jsfiddle.net/GUjPA/94/ here works

var state = false;
$("#toggle-slide-button").click(function () {
if (!state) {
$('#navBar').animate({width: "toggle"}, 1000);
$('#toggle-slide-button img').attr('src', 'http://i.imgur.com/K3MG7gT.png');
state = true;
}
else {
$('#navBar').animate({width: "toggle"}, 1000);
$('#toggle-slide-button img').attr('src', 'http://i.imgur.com/8BMxPsC.png');
state = false;
}
});
try this: you had added an m to the second call to #navbar

Progress bar with slide ability

I am new to JavaScript/CSS (basically the whole world of web dev) and I am really struggling to create the following widget. I created a picture of what I want to make to make it more clear.
The Play/Pause and Stop button are ready. Loop checkbox is no problem. But the progress bar is painful. The two markers are supposed to mark the point from where the file would start playing and where it would stop. The progress bar is also supposed to be click-able, so if I want to access a certain point in time, then its possible.
What I tried so far
jQuery UI slider: For a sliding progress bar and use that draggable slider to access a certain point in audio file. Works fine. But no markers and looks really ugly. Don't how to change it.
<progress> tag: not very flexible. Marker? Clicking?
<div> tag: there seems to be no way to get the point where I clicked.
So, what do you guys recommend? How should I proceed?

Canvas Alternative
You might want to use a canvas and draw your own progress bar element within it.
Here are some canvas progress bar tutorials:
How to create a progress bar with HTML5
A progress bar using HTML5 canvas
Doing it with <progress>
To access the clicked position within a DOMElement, you can proceed with the click event's properties: clientX and clientY (MDN Source), like so:
HTML
<div class="marker" id="StartMarker">^</div>
<div class="marker" id="StopMarker">^</div>
<progress id="progress" value="0" min="0" max="100">0%</progress>
<form id="choice">
<button id="marker1">Beginning marker</button>
<button id="marker2">Ending marker</button>
<input type="hidden" id="markerValue" value="0" />
</form>
JavaScript (not optimized)
document.getElementById('progress').onclick = function (event, element) {
/* Math.floor((event.offsetX / this.offsetWidth) * 100) */
var newProgress = event.offsetX;
document.getElementById('choice').style.display = "block";
document.getElementById('markerValue').setAttribute('value', newProgress);
document.getElementById('marker1').onclick = function (event) {
event.preventDefault();
var newProgress = document.getElementById('markerValue').value;
var progressBar = document.getElementById('progress');
var startMarker = document.getElementById('StartMarker');
var stopMarker = document.getElementById('StopMarker');
var marker = startMarker;
marker.style.display = "block";
startMarker.style.display = "block";
startMarker.offsetTop = (progressBar.offsetTop + progressBar.offsetHeight + 2) + "px";
startMarker.style.left = newProgress + "px";
};
document.getElementById('marker2').onclick = function (event) {
event.preventDefault();
var newProgress = document.getElementById('markerValue').value;
var progressBar = document.getElementById('progress');
var startMarker = document.getElementById('StartMarker');
var stopMarker = document.getElementById('StopMarker');
stopMarker.style.display = "block";
stopMarker.offsetTop = (progressBar.offsetTop + progressBar.offsetHeight + 2) + "px";
stopMarker.style.left = newProgress + "px";
};
};
CSS
.marker {
position:absolute;
top:24px;
left:9px;
display:none;
z-index:8;
font-weight:bold;
text-align:center;
}
#StartMarker {
color: #CF0;
}
#StopMarker {
color:#F00;
}
#choice {
display:none;
}
progress {
display: inline-block;

Using simple blocks for that is possible. Your layout would look like this (simplified):

background: green;
position: relative;
float: right;
}
.left {
background: white;
height: 100%;
}
}
}
}
The operations can be quite difficult
jQuery
$('.bar').click(function(e){
$(this).find('.progress').css('width', (e.offsetX / this.offsetWidth)*100+'%');
});
will set the Progressbar properly on clicks.
For the markers though you will need mousedown, mousemove, mouseleave events, since you got 2 of them.
