I have two buttons on an HTML page, and I'm trying to show them once a button is pressed, but only one actually displays.
This is the HTML
<button onclick="testLeft()" class="item-description" id= "left-item-description">.</button>
<button onclick="testRight()" class="item-description" id= "right-image-description">.</button>
This is the CSS
.item-description {
display: none;
box-sizing: border-box;
position: fixed;
z-index: 4;
font-size: 35px;
font-weight: 600;
height: auto;
top: 30%;
padding: 10px 10px;
color:white;
background-color: transparent;
border-radius: 4px;
border: 3px solid black;
transition: all 0.2s ease;
}
#left-item-description {
margin-left: 10%;
margin-right: 60%;
}
#right-image-description {
margin-right: 10%;
margin-left: 60%;
}
And this is the javascript
function newGame(){
score = -1;
increaseScore();
correct = true;
for (let i = 0; i < used.length; i++){
used[i] = false;
}
indexLeft = shuffleIndex();
indexRight = shuffleIndex();
var left = document.getElementById("left-item-description");
var righ = document.getElementById("right-item-description");
left.style.display = "block";
left.innerText = items[indexLeft];
document.getElementById("left-item-image").src=images[indexLeft];
righ.style.display = "block";
righ.innerText = items[indexRight];
document.getElementById("right-item-image").src=images[indexRight];
}
The left button works perfectly how I want it to, but for some reason, the right button doesn't display
The element ID for your right button is "right-image-description" but in your Javascript you are trying to get "right-item-description".
change the id attribute from this:
var righ = document.getElementById("right-item-description");
to
var righ = document.getElementById("right-image-description");
and it should work.

I have JS code on a webpage that loads questions in from mysql db and displays the text . What happens is that it cuts off words at the end of the line and continues the word on the next line at the start. So all text across the screen starts/ends at the same point.
This seems to be the code where it displays the text.
For example the text will look like at the end of a line 'cont' and then on next line at the start 'inue'.
How do i fix this?
var questions = <?=$questions;?>;
// Initialize variables
//------------------------------------------------------------------
var tags;
var tagsClass = '';
var liTagsid = [];
var correctAns = 0;
var isscorrect = 0;
var quizPage = 1;
var currentIndex = 0;
var currentQuestion = questions[currentIndex];
var prevousQuestion;
var previousIndex = 0;
var ulTag = document.getElementsByClassName('ulclass')[0];
var button = document.getElementById('submit');
var questionTitle = document.getElementById('question');
//save class name so it can be reused easily
//if I want to change it, I have to change it one place
var classHighlight = 'selected';
// Display Answers and hightlight selected item
//------------------------------------------------------------------
function showQuestions (){
document.body.scrollTop = 0; // For Safari
document.documentElement.scrollTop = 0; // For Chrome, Firefox, IE and Opera
if (currentIndex != 0) {
// create again submit button only for next pages
ulTag.innerHTML ='';
button.innerHTML = 'Submit';
button.className = 'submit';
button.id = 'submit';
if(quizPage<=questions.length){
//update the number of questions displayed
document.getElementById('quizNumber').innerHTML = quizPage;
}
}
//Display Results in the final page
if (currentIndex == (questions.length)) {
ulTag.innerHTML = '';
document.getElementById('question').innerHTML = '';
if(button.id == 'submit'){
button.className = 'buttonload';
button.innerHTML = '<i class="fa fa-spinner fa-spin"></i>Loading';
}
showResults();
return
}
questionTitle.innerHTML = "Question No:" + quizPage + " "+currentQuestion.question.category_name +"<br/>"+ currentQuestion.question.text;
if(currentQuestion.question.filename !== ''){
var br = document.createElement('br');
questionTitle .appendChild(br);
var img = document.createElement('img');
img.src = currentQuestion.question.filename;
img.className = 'imagecenter';
img.width = 750;
img.height = 350;
questionTitle .appendChild(img);
}
// create a for loop to generate the options and display them in the page
for (var i = 0; i < currentQuestion.options.length; i++) {
// creating options
var newAns = document.createElement('li');
newAns.id = 'ans'+ (i+1);
newAns.className = "notSelected listyle";
var textAns = document.createTextNode(currentQuestion.options[i].optiontext);
newAns.appendChild(textAns);
if(currentQuestion.options[i].file !== ''){
var br = document.createElement('br');
newAns .appendChild(br);
var img1 = document.createElement('img');
img1.src = currentQuestion.options[i].file;
img1.className = 'optionimg';
img1.width = 250;
img1.height = 250;
newAns .appendChild(img1);
newAns .appendChild(br);
}
var addNewAnsHere = document.getElementById('options');
addNewAnsHere.appendChild(newAns);
}
//.click() will return the result of $('.notSelected')
var $liTags = $('.notSelected').click(function(list) {
list.preventDefault();
//run removeClass on every element
//if the elements are not static, you might want to rerun $('.notSelected')
//instead of the saved $litTags
$liTags.removeClass(classHighlight);
//add the class to the currently clicked element (this)
$(this).addClass(classHighlight);
//get id name of clicked answer
for (var i = 0; i < currentQuestion.options.length ; i++) {
// console.log(liTagsid[i]);
if($liTags[i].className == "notSelected listyle selected"){
//store information to check answer
tags = $liTags[i].id;
// tagsClass = $LiTags.className;
tagsClassName = $liTags[i];
}
}
});
//check answer once it has been submitted
button.onclick = function (){
if(button.id == 'submit'){
button.className = 'buttonload';
button.innerHTML = '<i class="fa fa-spinner fa-spin"></i>Loading';
}
setTimeout(function() { checkAnswer(); }, 100);
};
}
//self calling function
showQuestions();
The website is on my local now but i can upload a screenimage if need be and the whole code of the webpage. Or is the issue in html?
edit: here is html/css code

I'm guessing that #question{ word-break: break-all; } is probably the culprit then? –
CB..yes that fixed it:)
I am dynamically adding new div's to a div container, the problem i'm facing is that the div is probably just a few pixels too big and therefore spawns a scrollbar that is pretty much useless, but with overflow: hidden; a little bit of the div gets cut off. I'm looking to make the div little bit larger in height, applying height: 100%; didn't work. This is how I'm creating the divs
function layerCreatorX(submission) { // creator for normal layers
let unique_id = uuidv4() // created unique IDs
let wrapDiv = document.createElement("div")
wrapDiv.id = "wrapDiv" + unique_id
let activeLayerIcon = document.createElement("IMG")
activeLayerIcon.setAttribute("class", "activeLayerOff")
activeLayerIcon.setAttribute("name", "activeLayerIcon")
let invisibilityIcon = document.createElement("IMG")
invisibilityIcon.setAttribute("class", "visibilityButtonPos invisibilityButton") // filter for grey
invisibilityIcon.setAttribute("name", "invisibilityIcon")
let visibilityIcon = document.createElement("IMG")
visibilityIcon.setAttribute("class", "visibilityButtonPos visibilityButtonOff")
visibilityIcon.setAttribute("name", "visibilityIcon")
let line = document.createElement("hr")
line.setAttribute("style", "margin-top: 0px;")
line.className = "greyLine" //grey line will go underneath the div
let x = document.createElement("span")
let t = document.createTextNode(submission)
layerArray.push(unique_id)
layerNamesForComparison.push(submission) //new name comparator
x.className = "item item-layer"
x.id = unique_id
t.className = "noselect"
x.appendChild(activeLayerIcon)
x.appendChild(t)
x.appendChild(invisibilityIcon)
x.appendChild(visibilityIcon)
wrapDiv.appendChild(x)
wrapDiv.className = "LayerListDiv"
document.querySelector('.LayerList').appendChild(wrapDiv)
document.querySelector('.LayerList').appendChild(line)
}
and this is how they look when I create them:
I want to get rid of the vertical scrollbar on the right but still be able to view the whole div, if I use overflow hidden, the <hr> line from the bottom gets cut off and I can't see it anymore.
.LayerList CSS:
.LayerList {
user-select: none;
overflow: auto;
right: -15px;
width: 100%;
max-height: calc(93% - 60px); /*This height has to stay*/
}

From W3Schools (https://www.w3schools.com/howto/howto_css_hide_scrollbars.asp):
/* Hide scrollbar for Chrome, Safari and Opera */
.example::-webkit-scrollbar {
display: none;
}
/* Hide scrollbar for IE, Edge and Firefox */

Where .example is the class of the div's with no scrollbar.
I'm trying to put go-to-top button in the bottom right angle of the screen. It should appear on scroll function, a disappear when I go back to top.
The button exists, but when I scroll down, it stays with "home page", so as I scroll more, it is not visible anymore. How to fix the problem? You can see my codes down here. Thanks a lot in advance!
window.onscroll = function(){goTop()};
let goTop = function() {
var rocket = document.querySelector(".go-to-top");
var scrollExt = document.body.scrollTop;
if(document.body.scrollTop > 500 || document.documentElement.scrollTop > 500){
rocket.style.display = "block";
} else{
rocket.style.position = "none";
}
};
let rocketClick = function() {
document.documentElement.scrollTop = 0;
}
.go-to-top{
display: none;
z-index: 10;
position: fixed;
bottom: 40px;
right: 40px;
width: 40px;
height: 40px;
transform: rotate(-45deg);
color: black;
padding: 10px;
text-decoration: none;
-webkit-box-sizing: border-box;
box-sizing: border-box;
}
.go-to-top i{
font-size: 50px;
}
.go-to-top:hover{
cursor: pointer;
text-decoration: none;
}
<!--the rest of markup-->
<div class="rocket">
<a href="#" class="go-to-top">
<i class="fas fa-rocket"></i>
</a>
</div>
<script src="script.js"></script>
<!--closing markup-->
rocket.style.position:none would give your element the css style of position:none. none is not a valid value for the position property.
You can see the position values here -> CSS position
By the look of your code you would need to use display instead of position.
Also, you make a variable scrollExt and you do not use it. Plus, you make a rocketClick function but you do not call it on your element.
window.onscroll = function() {
goTop();
};
const goTop = function() {
const rocket = document.querySelector('.go-to-top');
const scrollExt = document.body.scrollTop;
if (scrollExt > 500 || document.documentElement.scrollTop > 500) {
rocket.style.display = 'block';
} else {
rocket.style.display = 'none';
}
};
const rocketClick = function() {
document.documentElement.scrollTop = 0;
};
main {
height:1500px;
background:red;
}
.go-to-top{
display: none;
z-index: 10;
position: fixed;
bottom: 40px;
right: 40px;
width: 40px;
height: 40px;
transform: rotate(-45deg);
color: black;
padding: 10px;
text-decoration: none;
-webkit-box-sizing: border-box;
box-sizing: border-box;
}
.go-to-top i{
font-size: 50px;
}
.go-to-top:hover{
cursor: pointer;
text-decoration: none;
}
<main></main>
<div class="rocket" onclick=rocketClick()>
<a href="#" class="go-to-top">
rocket icon
</a>
</div>
Suggestions :
Keep using let and const. Do not use var. Also, use const for your functions. You do not change the content of the functions anywhere so you can use const instead of let.
Add an animation(transition) to the scrollTop.
I've tried to look for a solution for this but have failed miserably. It's my first ever time using JS (I'm trying to learn) so the possibility of my just not understanding the answers in the search results properly is quite high - sorry about that.
I am wanting a JS carousel, generated from an array, with Prev/Next buttons (ideally responsive etc but that'll come at a later stage), preferably with captions underneath. I can get the carousel to work but I end up getting a text link when I click on either Prev or Next. And I've no idea how to add the caption array underneath (I've taken out the JS for the captions for now because it was messing everything else up even further).
Relevant HTML:
<body onload="changePilt()">
<span id="prev" class="arrow">❮</span>
<div class="karussell" id="karussell">
<img class="karu" name="esislaid">
</div>
<span id="next" class="arrow">❯</span>
<div class="caption">
<h3 name="esikiri"></h3>
</div>
</body>
CSS, just in case:
.karussell {
position: relative;
width: 100%;
max-height: 600px;
overflow: hidden;
}
.arrow {
cursor: pointer;
position: absolute;
top: 40%;
width: auto;
color: #00A7E0;
margin-top: -22px;
padding: 16px;
font-weight: bold;
font-size: 18px;
transition: 0.6s ease;
border-radius: 0 3px 3px 0;
}
#next {
right: 0;
border-radius: 3px 0 0 3px;
}
#prev {
left: 0;
}
.arrow:hover {
background-color: rgba(0,0,0,0.8);
}
.caption {
text-align: center;
color: #00A7E0;
padding: 2px 16px;
}
.karu {
max-width: 75%;
}
#media (max-width:767px){.karu{max-width: 95%;}}
And finally, the dreaded JS:
var i = 0;
var s = 0;
var esileht = [];
var aeg = 5000;
//Image List
esileht[0] = 'img/tooted/raamat/graafvanalinn2016.jpg';
esileht[1] = 'img/tooted/kaart/kaart_taskus_esipool.jpg';
esileht[2] = 'img/tooted/kaart/graafkaart_esikylg.jpg';
//Change Image
function changePilt (){
document.esislaid.src = esileht[i];
if(i < esileht.length -1){
i++;
} else {
i = 0;
}
setTimeout("changePilt()", aeg);
}
document.onload = function() {
}
// Left and Right arrows
//J2rgmine
function jargmine(){
s = s + 1;
s = s % esileht.length;
return esileht [s];
}
//Eelmine
function eelmine(){
if (s === 0) {
s = esileht.length;
}
s = s -1;
return esileht[s];
}
document.getElementById('prev').addEventListener('click', function (e){
document.getElementById('karussell').innerHTML = eelmine();
}
);
document.getElementById('next').addEventListener('click', function (e) {
document.getElementById('karussell').innerHTML = jargmine();
}
);
I'm sure the solution is dreadfully obvious, I just cannot seem to be able to figure it out...
instead of innerHTML change src attribute of image
document.querySelector('#karussell img').src = eelmine();
And
document.querySelector('#karussell img').src = jargmine();
I have the following function that resets a button and applies styling once it is executed:
function reset(){
var boxes = getBoxes();
for(i = 0 ; i < boxes.length; i++) {
boxes[i].innerHTML = "";
}
document.getElementById("start_button").innerHTML = "Start Game";
document.getElementById("start_button").setAttribute('onclick', 'gameStart()');
document.getElementById("start_button").style.color = "black";
document.getElementById("start_button").style.backgroundColor = "lightgreen";
}
However, as you can see, it is getting repetitive to change each style element in the function. Especially if I want this style to be applied:
#button{
text-align: center;
}
#start_button{
width: 10%;
height: 50px;
margin-top: 4%;
margin-left: auto;
margin-right: auto;
background: lightgreen;
color:black;
}
#start_button:hover {
background: green;
color: white;
}
Is there a way in JavaScript to link to an entire block of style code?
If you change the start_button to a class; which it should be because there will be more than one of them on the page; you can use the className property.
CSS:
.start_button{
width: 10%;
height: 50px;
margin-top: 4%;
margin-left: auto;
margin-right: auto;
background: lightgreen;
color:black;
}
.start_button:hover{
background:green;
color: white;
}
Look like you are creating buttons so you can grab the buttons
JS:
document.getElementsByTagName("button").className = "start_button";
