Is there any method or JavaScript library that can see if an element is really fully visible? As an example, suppose you need some UI button shown between certain elements and not take up more space on the page, as on this example:
https://jsfiddle.net/akyh7e5f/
html:
<div style="width:50%; display:inline-block">
<div class="a">
<div>
Some content here.
</div>
<div class="inserter">
insertme
</div>
</div>
<div class="b">
<div>
some other content
</div>
</div>
</div>
<div style="width:49%; display:inline-block">
<div class="a" style="z-index:1">
<div>
Some content here.
</div>
<div class="inserter">
insertme
</div>
</div>
<div class="b" style="z-index:2">
<div>
some other content
</div>
</div>
</div>
css:
.a {
height:80%;
background: blue;
position:relative;
}
.b {
padding:30px;
background:green;
position:relative;
}
.inserter {
position:absolute; z-index:9999;
left:50%; margin-left:-20px;
background: red;
}
In one case the element is inside and shows, in the other case it is under because some other element has more zindex than a container of the insertme element. I could make it body > element direct child, but then EVERY change to the height of the element would required a change to the position.
You could move the red element up one dom element until it is after the element and visible, then do some calculations for top/left,
or, perhaps more performant, change it from absolute to relative and make it take up space, in the second case it will not show (which is not as great from a design perspective).
In either of these two cases, I need to know whether the element (red element in this fiddle) is actually visible and clickable with no element above it. Is there any library that can find this?
Please do not reply with a specific suggestion for the jsfiddle - this is a minimal test case, assume many different styles may theme the page in any way, not to mention user-added styles. Also please do not mention Selenium as this has to be a browser-only dynamic app.
Can use elementFromPoint() to test if the element you want is the top element at it's offset coordinates.
This is not a full test for your issue but should help give you part of it
$('.inserter').each(function(){
var offset= $(this).offset();
var topEl = document.elementFromPoint(offset.left, offset.top);
console.log(topEl == this)
})
Note I only checked the top left corner, you would probably want to see if more of it is displayed than just that corner.
DEMO
For puppeteer I needed this and used #charlietfl answer to do it but with more checks
await page.waitForFunction(
(browserSelector) => {
const browserElement = document.querySelector(browserSelector);
if (!browserElement) {
console.log(`Cannot find element "${browserSelector}"`); // eslint-disable-line no-console
return false;
}
const boundingBox = browserElement.getBoundingClientRect();
if (boundingBox.width === 0) {
console.log(`Element "${browserSelector}" has no width`); // eslint-disable-line no-console
return false;
}
if (boundingBox.height === 0) {
console.log(`Element "${browserSelector}" has no height`); // eslint-disable-line no-console
return false;
}
const clickTarget = document.elementFromPoint(
boundingBox.left + boundingBox.width / 2, // Horizontal center
boundingBox.top + boundingBox.height / 2, // Vertical center
);
if (!browserElement.contains(clickTarget)) {
console.log(`Element "${browserSelector}" is obstructed`); // eslint-disable-line no-console
return false;
}
return true;
},
{}, // No options for waitForFunction
selector,
);

I have two issues that I was hoping to address
Problem-1: I have a website called dirieahmed. ml (the same as the code sandbox) I have a night mode / light mode toggle, however when I click on night mode my logo (the image which is called hello.jpg and is above the face picture) will stay the same which makes sense but looks terrible because it looks like an imperfect white square. As a result, I wanted to change this. Therefore when I click on night mode I want the image to change into the night mode version of the logo I have made (it will be called hello-dark.jpg) Is there a way i can do that? I will link the appropriate code down below but if you would like to see the CSS you can view the sandbox
<div class="image1">
<img src="img/hello.jpg" alt="something" width="400" height="300">
</div>
<script async>
<--!This is my dark theme toggle-->
document.querySelector('.theme-toggle-button').addEventListener('click', () => {
document.body.classList.toggle('dark')
})
Problem-2: On my sandbox, you can view an About me, Education and Achievements and Other content elements, these elements are buttons when clicked they will drop down a content, if I click on about me then Education about me will open then close and allow Education to open. Pretty Normal and similarly for the button called "Other" but when i click on Other again to reset all the views and make it clean like when it was originally where no dropdowns exsisted that wont happen. Is there a way for me to make a javascript that will close all content from that div when clicked on it twice. (the code of CSS is in the sandbox but Html and JS will be here)
<div class="container">
<button id="one" class="click one" title="click me">About Me</button>
<div class="list-1 sec">
<h1 class="content-header-one content">Dummy text header</h1>
<p class="content-paragraph-one">Dummy text</p>
</div>
<button class="click two" title="click me">Education and Achivements</button>
<div class="list-2 sec">
<p class="content-paragraph2 content">Dummy text</p>
<ul class="content-list content">
<li>- Achivement #1</li>
<li>- Achivement #2</li>
<li>- Achivement #3</li>
</ul>
</div>
<button class="click three" title="click me" >Other</button>
<div class="list-3 sec">
<h1 class="content-header-two content">Dummy text header</h1>
<p class="content-paragraph3 content">Dummy text</p>
</div>
<script async>
// Instanciate List div's
let list1 = document.querySelector(".list-1");
let list2 = document.querySelector(".list-2");
let list3 = document.querySelector(".list-3");
// Reset's all views to the default without .newlist
const resetAllViews = () => {
list1.classList.remove("newlist");
list2.classList.remove("newlist");
list3.classList.remove("newlist");
};
// Checks to see what button is clicked and shows correct list based on input
document.addEventListener(
"click",
function (e) {
e = e || window.event;
var target = e.target;
if (target.classList.contains("one")) {
resetAllViews();
list1.classList.add("newlist");
}
if (target.classList.contains("two")) {
resetAllViews();
list2.classList.add("newlist");
}
if (target.classList.contains("three")) {
resetAllViews();
list3.classList.add("newlist");
}
}, false);
</script>
</div>
Again you can view the result I have in the sandbox (latest) and on the most recent website dirieahmed.ml for real life view
Sorry if I repeated myself a lot and any help would be appreciated though I prefer if you can show me the code as a runner snippet as I am fairly new so its a bit difficult for me to understand all vocabulary but again any help is appreciated
As for the 1st point, i think you have 2 possibilities:
Add the image as a background image with css, so you can easily toggle. Normally you show the "light" image, and if the body has the dark class then you can show the "dark" image.
The second idea is to add two <img> elements to the page and hide / show accordingly, something like:
.image-light {
display: block;
}
body.dark .image-light {
display: none;
}
.image-dark {
display: none;
}
body.dark .image-dark {
display: block;
}
As to the 2nd point i think you should to it like this:
you have a variable to hold the current open element
when you click a button you get the "value" vor that button
If the value if the same as the current open variable, then you reset the variable (maybe to null), otherwise you set the current open variable to the value of that button
Then you can have an update function. On this function you go through all the of "target" elements. If the element corresponds to the currently open variable, you open it, otherwise you close it.
Something like:
let currentlyOpen = null;
let buttons = document.querySelectorAll(".your-buttons");
let targets = document.querySelectorAll('.your-targets');
button.forEach((button) => {
button.addEventListener('click', (event) => {
const newTarget = event.target.getAttribute('your-identifier-attribute');
currentlyOpen = currentlyOpen === newTarget ? null : newTarget;
updateUI();
});
})
function updateUI() {
targets.forEach((target) => {
targetIdentifier = target.getAttribute('the-identifier-attribute');
targetIdentifier === currentlyOpen
? target.classList.add('your-class-for-open-list')
: target.classList.remove('your-class-for-open-list');
})
}
I have created an example for you:
let openContent = null;
const buttons = document.querySelectorAll('button');
const contents = document.querySelectorAll('.content');
buttons.forEach((button) => {
button.addEventListener('click', (event) => {
const newTargetId = event.target.getAttribute('target-id');
openContent = newTargetId === openContent ? null : newTargetId;
updateUI();
});
});
function updateUI() {
contents.forEach((content) => {
const contentId = content.getAttribute('id');
contentId === openContent
? content.classList.add('visible')
: content.classList.remove('visible');
});
}
.content {
display: none;
}
.content.visible {
display: block;
}
<p> click one of the buttons to show more content</p>
<button target-id="one">One</button>
<button target-id="two">Two</button>
<button target-id="three">three</button>
<p class="content" id="one">Content one</p>
<p class="content" id="two">Content two</p>
<p class="content" id="three">Content three</p>
Here is an example of doing this using two elements where one is hidden based on theme. You could make it a photo that you want to change. This way both images are loaded and you don't have to have the client wait for an image to load when themes change.
The way I accomplished this was mainly in css. The only javascript is to toggle the dark class on the page. The dark page has css variables which represent whether or not elements on the page have a display of none or block. On the actual elements which toggle, I feed those css variables into them. It is also possible to add animations or transitions to make it feel fancy, but hopefully this small demonstration satisfies your need for modifications to your own project.
const $ = str => document.querySelector(str);
const page = $(".page");
$(".theme-toggle").addEventListener("click", () => {
page.classList.toggle("dark");
});
body {
display: grid;
place-items: center;
}
.page {
--light-logo: block;
--dark-logo: none;
display: flex;
flex-direction: column;
text-align: center;
}
.page.dark {
--light-logo: none;
--dark-logo: block;
background-color: black;
color: white;
}
.logo-container {
font-size: 5rem;
}
.logo-container .dark {
display: var(--dark-logo);
}
.logo-container .light {
display: var(--light-logo);
}
<div class="page">
Hello World
<div class="logo-container">
<div class="light">🌞</div>
<div class="dark">🌑</div>
</div>
<button class="theme-toggle">🌞 / 🌑</button>
</div>
Answer 1: It is possible to simple solve by CSS, but this is not good idea for the SEO optimization. Better and most simple solution is to use 2 images and add class "hidden", where you will set for this class {display:none} in css file. Next you must modify your script to set/remove "hidden" class by the selected light/dark mode.
<div class="image1">
<img src="img/hello.jpg" alt="something" width="400" height="300">
</div>
Another better solution is modify the DOM, replace img element when mode is changed, or change the src attribute, e.g.:
document.getElementById("myImageId").src="img/hello-dark.jpg";
Is there an easy way to highlight a top with id (apply css-class with specific color f.e.) after user scrolls to it? I have a scrollspy on page, but it seems that plugin will not help me, so I can't make to ends meet.
P.S. I didn't find alike info in Google or StackOverflow, so please, don't get me wrong.
There is a rough example of page
https://jsfiddle.net/masyurik/kdnzdeb2/#&togetherjs=DeaMiBADpp
HTML
<div id="secA" class="section">
Hello it's secA
<div>
<br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br>
</div>
</div>
<div id="secB" class="section">
Hello it's secB
<div>
<br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br>
</div>
</div>
<div id="secC" class="section">
Hello it's secC
<div>
<br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br>
</div>
</div>
CSS
.section {
background-color: red;
}
.active {
background-color: yellow;
}
You need to use scrollevent and change the class accordingly... kindly check https://jsfiddle.net/77v3329y/1/
jQuery
$(document).ready(function() {
var a = +$('#secA').height();
var b = $('#secB').height();
var c = $('#secC').height();
console.log(a);
console.log(b);
console.log(c);
$(window).on('scroll', function() {
$('#secA, #secB, #secC').removeClass('active');
var st = $(document).scrollTop();
if (st < a) {
$('#secA').addClass('active');
}
if (st > a) {
$('#secB').addClass('active');
}
if (st > a + b) {
$('#secC').addClass('active');
}
})
});
You can use jquery-waypoints to know which element has reached at top of the viewport. The plugin will give you the callback which will help you to change the css of the active element.
Here is the solutions to detect the scroll to top event.
Fire event when div is visible to visitor with jQuery?
Simply use jQuery to change the css of the element when scroll to top: $("#secA").css("background-color", "yellow");
Well, i am stucked and can't find the answer myself. Hopefully someone can give me a hint.
I try to fullfill the following requirements:
There should be a Newsblock within a HTML Page with a fixed width and
height.
In this Newsblock only the title of the news are visible.
Those news are "collapsed" by default and should "expand" if the Mouse is over it.
Due the fact that the 'Newsblock' is limited by its height, there should be a Scrollbar visible. But only if the currently expanded news makes it necessary, so the user can Scroll down.
Newstitle and Newstext should never leave the Newsblock.
so far so good, i was able to fullfill all those demands except the one with the Scrollbar. If i try to reach the Scrollbar out of the currently expanded news it collapses again and the Scrollbar disappears. I understand that my .hover is configured that it always SlideUp if i leave the newsentry and the Scrollbar isn't a part of the newsentry div. But i have no idea what to change to still have an overall Scrollbar for the Newsblock, but won't disappear if i try to 'reach' it.
P.s.: A Scrollbar only per Newsentry looks weird. Thats why i want 'bind' the scrollbar to the parent container :S
HTML
<div id="newsblock">
<div> // some auto generated div's i have to life with, so the news entries are not 'direct' children of the newsblock.
<div class="newsentry">
<div class="newstitle">...</div>
<div class="newstext">...</div>
</div>
... another 9 'newsentry' divs.
</div>
</div>
JS
$(".newsentry").hover(
function() {
$(this).children(".newstext").stop(true,true).slideDown();
},
function() {
$(this).children(".newstext").stop(true,true).slideUp();
}
);
CSS
.newsblock {
height: 200px;
overflow-y: auto;
}
Instead of closing a .newsentry when the cursor goes out of it, a solution can be to close it only when it enters another .newsentry or when it leaves #newsblock.
The scrollbar being part of #newsblock, the entry isn't closed anymore when you go on it.
EDIT: Following our discussion about the scroll issue, I added a step callback to the closing animation to make sure that the top of the .newsentry getting opened remains visible when the other entries are getting closed.
Here is a working example:
var $newsblock = $("#newsblock");
function closeAllNews(slideUpArgs){
return $(".newstext").stop(true).slideUp(slideUpArgs);
}
function openNews(news, slideDownArgs){
$(news).find(".newstext").stop(true).slideDown(slideDownArgs);
}
function ensureNewsTopVisible(news){
// Check if the top of the newsentry is visible...
var top = $(news).position().top;
if(top < 0){
// ...and if not, scroll newsblock accordingly.
$newsblock.scrollTop($newsblock.scrollTop() + top);
}
}
$(".newsentry").each(function(){
var $this = $(this);
// When the mouse enter a news entry...
$this.on("mouseenter", function(){
// ...close all opened entries (normally there is at most one)...
closeAllNews({
// (while making sure that the top of this entry remains visible
// at each step)
step: ensureNewsTopVisible.bind(null, $this)
});
// ...open this newsentry.
openNews($this);
});
});
// When the mouse get out of the newsblock, close all news.
$newsblock.on("mouseleave", closeAllNews);
.newstitle {
font-size: 2em;
}
.newstext {
display: none;
}
#newsblock {
max-height: 150px;
overflow: scroll;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="newsblock">
<div>
<div class="newsentry">
<div class="newstitle">News 1</div>
<div class="newstext"></div>
</div>
<div class="newsentry">
<div class="newstitle">News 2</div>
<div class="newstext"></div>
</div>
<div class="newsentry">
<div class="newstitle">News 3</div>
<div class="newstext"></div>
</div>
<!-- Etc. -->
</div>
</div>
<!-- Ignore the script below. It is just filling in the news' text. -->
<script>
$(".newstext").each(function(i, newstext){
$.get("http://baconipsum.com/api/?type=meat-and-filler&format=html¶s=5&num=" + i)
.then(function(ipsumHtml){
$(newstext).html(ipsumHtml);
});
});
</script>
Try this:
$(".newsentry, .newsblock").hover( // <-- changed
function() {
$(this).children(".newstext").stop(true,true).slideDown();
},
function() {
$(this).children(".newstext").stop(true,true).slideUp();
}
);
This makes sure the block stays open when you hover either over the header or the block itself.
Is that what you mean?
There would be a joke , if i am wrong .. what i thing just change your css as
/* not .newsblock **/
#newsblock {
height: 200px;
overflow-y: scroll;/* not auto*/
}
It will be a lot better if you use click operation instead of hover to slide down news text block because the user can accidentally hover over any of the news entry in order to reach for the scroll bar. I think you need a accordion like functionality. You can use the below code if you are fine with click instead of hover.
$(".newsentry").click(
function() {
$(".newstext").stop(true,true).slideUp();
$(this).children(".newstext").stop(true,true).slideDown();
}
);
Or use the below one to go with hover.
$(".newsentry").hover(
function() {
$(".newstext").stop(true,true).slideUp();
$(this).children(".newstext").stop(true,true).slideDown();
},
function(){}
);
This will not close the news text block until you accidentally hover over another news entry.
I have 5 divs that contain copy.
I have a back and next button, to display each div.
Back | Next
<div class="vote-result first">
this is example copy
</div>
<div class="vote-result">
this is some more copy
</div>
<div class="vote-result">
some more copy
</div>
<div class="vote-result">
this is the last div
</div>
// hide the divs, except the first one.
.vote-result { display: none; }
.vote-result.first { display: block; }
The first time the next button link is clicked, I want to remove the off class, to show it as clickable, I probably should disable the link initially too and re-enable it too.
$(".back-btn").removeClass("off");
Once I display the last div, I need to add the off class to the next-btn and disable it.
I thought about using a carousel js plugin to accomplish this, but it is overkill for now.
I know of a way to do this, but it would involve assigning subclasses to the links based on what next or back button was clicked, so it will know what div to show next, as well as removing or adding the off class to the links.
I am hoping to find a solution that allows me to add more div's to display without modifying the code. Any help is appreciated, thank you.
Here is solution for you. I have created Fiddle for your requirement.
HTML code:
<a class="back-btn off">Back</a> | <a class="next-btn">Next</a>
<div class="vote-result first selectedDiv">
this is example copy
</div>
<div class="vote-result">
this is some more copy
</div>
<div class="vote-result">
some more copy
</div>
<div class="vote-result last">
this is the last div
</div>
JS/JQuery Code:
$(".back-btn").click(function(){debugger;
var prevElement=$('.selectedDiv').prev();
prevElement.show();
$(".selectedDiv").hide();
$(".selectedDiv").removeClass("selectedDiv");
prevElement.addClass("selectedDiv");
if($('.first').css('display')=="block"){
$(".back-btn").addClass("off");
}
else{
$(".next-btn").removeClass("off");
}
});
$(".next-btn").click(function(){debugger;
var nextElement= $('.selectedDiv').next();
nextElement.show();
$(".selectedDiv").hide();
$(".selectedDiv").removeClass("selectedDiv");
nextElement.addClass("selectedDiv");
if($('.last').css('display')=="block"){
$(".next-btn").addClass("off");
}
else{
$(".back-btn").removeClass("off");
}
});
CSS code:
.vote-result { display: none; }
.vote-result.first { display: block; }
.off{display:none;}
Your HTML file:
<html>
<head>
<style>
.vote-result { display: none; }
.vote-result.first { display: block; }
.off {
color: Red;
}
a {
color: blue;
}
</style>
<script src="//code.jquery.com/jquery-1.11.0.min.js"></script>
<script src="code.js"></script>
</head>
<body>
Back | Next
<div class="vote-result first">
this is example copy
</div>
<div class="vote-result">
this is some more copy
</div>
<div class="vote-result">
some more copy
</div>
<div class="vote-result">
this is the last div
</div>
</body>
</html>
Your new "code.js" file in the same directory:
/**
* The zero-based index of the <div class="vote-result"> element that is currently being shown
* #var {Number}
*/
var activeIndex = 0;
function getNumberOfItems() {
return $('.vote-result').length;
}
function synchronizeInterface() {
var numberOfItems = getNumberOfItems(),
lastIndex = numberOfItems - 1;
$('.vote-result').removeClass('first');
$('.vote-result').each(function(index) {
if (index == activeIndex) {
$(this).addClass('first');
}
})
$('.back-btn').toggleClass('off', activeIndex == 0);
$('.next-btn').toggleClass('off', activeIndex == lastIndex);
}
$(function() {
$('.back-btn,.next-btn').on('click', function() {
// If the button clicked is not deactivated
if (!$(this).hasClass('off')) {
// Determine whether the "Next" button was clicked (otherwise "Back" was clicked)
var clickedNext = $(this).hasClass('next-btn');
// Move the active index in the appropriate direction while not allowing it to fall outside the boundaries of appropriate indices
activeIndex = clickedNext
? Math.min(activeIndex + 1, getNumberOfItems() - 1)
: activeIndex = Math.max(0, activeIndex - 1);
// Make sure the interface now reflects the updated JavaScript variables
synchronizeInterface();
}
return false;
});
});
Some notes: You had an unclosed double-quote for one of your class attributes in your provided HTML. Also, I added some additional styling -- you may want to rename the ".first" CSS class to ".active" instead.
take a look at jquerys .next() function for navigating - jQuery - Next(). you can also check for the last item like this.
if($(this).is(':last-child'))
{
$('.next-btn').removeClass('off');
}else{
$('.next-btn').addClass('off');
}
check everytime a navigation button is clicked and do the same for the first button
I have a slider that's in place on my website.
The basic way that it works is depicted in this jsfiddle -
http://jsfiddle.net/6h7q9/15/
I've written code to set the parent's height to the height of the content div. This worked fine, until I introduced some content that did not have a fixed height and whose height might increase while it was being shown on the page. Is there a way, I can dynamically change the height of this parent div whenever content inside it increases or decreases it's height.
HTML -
<div id="slider_container">
<div id="slider">
<div id="slide1">
Has content that might increase the height of the div....
</div>
<div id="slide2">
Has content that might increase the height of the div....
</div>
<div id="slide3">
Has content that might increase the height of the div....
</div>
</div>
</div>
<input type="button" value="Next" id="btnNext">
<input type="button" value="Previous" id="btnPrev">
<input type="button" value="Add text" id="btnAddText">
<div class="footer">
I appear after the largest container, irrespective of which one is present....
</div>
JavaScript -
var currSlider = 1;
$('#btnNext').click(function(){
debugger;
var margin = $('#slider').css('margin-left');
if(parseInt(margin) <= -400) {
return;
}
currSlider++;
// Moving the slider
$('#slider').css('margin-left', parseInt(margin) - 200 + 'px');
// Resetting the height...
$('#slider').height($('#slide' + currSlider).height());
});
$('#btnPrev').click(function(){
debugger;
var margin = $('#slider').css('margin-left');
if(parseInt(margin) >= 0) {
return;
}
currSlider--;
// Moving to the previous slider
$('#slider').css('margin-left', parseInt(margin) + 200 + 'px');
// Resetting the height...
$('#slider').height($('#slide' + currSlider).height());
});
$('#btnAddText').click(function() {
$('#slide' + currSlider).text('Hello World'.repeat(100));
});
String.prototype.repeat = function(times) {
return (new Array(times + 1)).join(this);
};

An example on how to use: (DOMSubtreeModified didn't work in IE from what i read. Therefor the propertchange event)
$('#slide1').on('DOMSubtreeModified propertychange', function() {
console.log('test',this);
});
Another option is by using the MutationObserver:

Since i totally misread the original post, this answer was useless to say the best. But since the problem is actually really easy to solve (or... at least i hope i understand the problem this time), i thought i'd post an answer that worked for the situation: a slider with content of different heights.
What was the problem with the original slider? You moved the content out of the container, which made it hidden. However, the container would still pick up the height of it, since it only had a fixed width. The fixed height on the '#slider' did not prevent the container of picking up the height from the '#slide-*'. Had you set the height for the container... all would be fine :-)
Here's the outline of the hidden slide, moved 'off canvas': http://i.gyazo.com/f2404e85263a7209907fdbc8f9d8e34e.png
I did not fix your fiddle by completing your code. I just rewrote it to provide you with an easier to maintain slider. Here's a fiddle with a working slider where you can add and remove stuff in the slides: http://jsfiddle.net/3JL2x/3/
Just remove the height properties in the .slide1, 2 and 3 and add min-height instead.
Like that :
#slider > div {
min-height:200px;
float:left;
width : 200px;
}
#slide1 {
background-color : red;
}
#slide2 {
background-color: green;
}
#slide3 {
background-color: blue;
}
