I have this script that is designed to mention which section is in sight in a overflow div so for example if you see a specific section it will say section 1 is in sight if you see
more than 1 section in sight it will say something like for example section 1 is in sight and section 2 is in sight etc...
How can I do something like this? I can't figure this out I tried many things but I can not be able to do what I want :(
This is my code
document.addEventListener('DOMContentLoaded',function(){
document.querySelector('#building').addEventListener('scroll',whichSectionsAreInSight);
function whichSectionsAreInSight(){
//???
}
});
h1{
margin: 0;
text-align: center;
}
#building{
background-color: gray;
height: 200px;
width: 200px;
overflow: auto;
}
.sections{
height: 225px;
width: 100%;
}
#section-1{
background-color: dodgerblue;
}
#section-2{
background-color: gold;
}
#section-3{
background-color: red;
}
<div id='building'>
<div id='section-1' class='sections'><h1>Section 1</h1></div>
<div id='section-2' class='sections'><h1>Section 2</h1></div>
<div id='section-3' class='sections'><h1>Section 3</h1></div>
</div>
<p id='status'></p><!--------The id call status is responsible
in mentioning which section is in sight-->
Hello this is my version of Mohammad's code and your code James. All credit goes to Mohammad and any up votes should go to Mohammad here it goes with the IE fix, my version
document.addEventListener('DOMContentLoaded',function(){
document.querySelector('#building').addEventListener('scroll',whichSectionsAreInSight);
function whichSectionsAreInSight(){
var building= document.querySelector('#building');
var top = building.scrollTop;
var bottom = top+building.offsetHeight;
var arr = [];
Array.prototype.forEach.call(
building.querySelectorAll('#building .sections'),
function(sections){
if ((sections.offsetTop < top && top <sections.offsetTop+sections.offsetHeight) || (sections.offsetTop < bottom && bottom < sections.offsetTop+sections.offsetHeight)){
arr.push(sections.id);
}
}
);
document.querySelector('#status').innerHTML = arr.join(',')
}
whichSectionsAreInSight();
});
h1{
margin: 0;
text-align: center;
}
#building{
background-color: gray;
height: 200px;
width: 200px;
overflow: auto;
}
.sections{
height: 225px;
width: 100%;
}
#section-1{
background-color: dodgerblue;
}
#section-2{
background-color: gold;
}
#section-3{
background-color: red;
}
<div id='building'>
<div id='section-1' class='sections'><h1>Section 1</h1></div>
<div id='section-2' class='sections'><h1>Section 2</h1></div>
<div id='section-3' class='sections'><h1>Section 3</h1></div>
</div>
<p id='status'></p>
In scroll event of parent loop through childs and check that which one in visible and add id of it to array. Al the end print array content into page
document.querySelector('#building').addEventListener('scroll', function(){
var top = this.scrollTop;
var bottom = top+this.offsetHeight;
var arr = [];
this.querySelectorAll("div").forEach(function(div){
if (
(div.offsetTop < top && top <div.offsetTop+div.offsetHeight) ||
(div.offsetTop < bottom && bottom <div.offsetTop+div.offsetHeight)
){
arr.push(div.id);
}
});
document.getElementById("status").innerHTML = arr.join(",")
});
h1{
margin: 0;
text-align: center;
}
#building{
background-color: gray;
height: 200px;
width: 200px;
overflow: auto;
}
.sections{

}
#section-1{

I'm trying to add height to original value in CSS.
But so far I had no luck.
html,
body {
width: 100%;
height: 100vh;
margin: 0px 0px 0px 0px;
overflow: hidden;
background-color: #FFF;
}
#Header1 {
background-color: green;
width: 100vw;
height: 10vh;
margin-bottom: 0%;
z-index: 100;
}
#Header2 {
background-color: blue;
width: 100%;
height: 4vh;
margin-bottom: 0%;
z-index: 100;
}
#Main {
height: 82vh;
width: 100%;
}
if (Header1Check == 1) {
document.getElementById("Header1").style.display = "block";
} else {
document.getElementById("Header1").style.display = "none";
document.querySelector('#Main').style.height = "initial" + "10vh";
}
if (Header2Check == 1) {
document.getElementById("Header2").style.display = "block";
} else {
document.getElementById("Header2").style.display = "none";
document.querySelector('#Main').style.height = "initial" + "4vh";
}
Basicly if the check = 0 it stops showing HEADER1/Header2, but the Main content (center) does not auto size to this.
To counteract this I just tried to add that value to the CSS but it does not appear to work.
Is there a way to achieve this?
edit:
<body>
<div id="wrapper">
<div id="Header1">
</div>
<div id="Header2">
</div>
<div id="portraitContent">
</div>
<div id="landscapeContent">
</div>
<div id="Footer">
</div>
</div>
</body>
You can use display:flex on the #wrapper element, and then set the content divs with flex:1 which means they will take up the remaining space
(see more about flexbox at: https://developer.mozilla.org/en-US/docs/Learn/CSS/CSS_layout/Flexbox)
Something like
*{box-sizing:border-box;}
html,
body {
width: 100%;
height: 100vh;
margin: 0px 0px 0px 0px;
overflow: hidden;
background-color: #FFF;
}
#wrapper {
display: flex;
flex-direction: column;
height: 100vh;
}
#wrapper > * {
border: 1px solid black;
}
#Header1 {
background-color: green;
height: 10vh;
z-index: 100;
}
#Header2 {
background-color: blue;
height: 4vh;
}
#Footer {
background-color: tomato;
height: 4vh;
}
#portraitContent,
#landscapeContent {
flex: 1;
background: teal;
}
#media (orientation: landscape) {
#portraitContent {
display: none
}
}
#media (orientation: portrait) {
#landscapeContent {
display: none
}
}
<div id="wrapper">
<div id="Header1"> header 1
</div>
<div id="Header2">header 2
</div>
<div id="portraitContent">
portrait
</div>
<div id="landscapeContent">
landscape
</div>
<div id="Footer">footer
</div>
</div>
Assuming you want to change size of an image for example you can do this simple example below
Also the property you added for height is incorrect syntax
The correct property values are from
https://www.w3schools.com/jsref/prop_style_height.asp
Property Values
Value Description
auto The browser sets the height. This is default
length Defines the height in length units
% Defines the height in % of the parent element
initial Sets this property to its default value. Read about initial
inherit Inherits this property from its parent element. Read about inherit
#HaoWu comment is correct you cannot use both properties together either or
you can assign another
//Syntax : object.style.height("")
appImg.style.height = "inital";
Refernces
prop style height w3schools
js-conventions w3schools
I have prepared a simple Example answer for your question .
const appImg = document.getElementById("appImg");
//console.log(appImg);
function minimizeImage(){
const hideImgBtn = document.getElementById("hideImgBtn");
if(!hideImgBtn){
appImg.style.display = "block";
}else {
appImg.style.height = "10vh";
};
};
.app__img{
max-width: 10vw;
max-height: 150px;
width: 100%;
height: 100%;
}

document.querySelector('#Main').style.height = "initial" + "10vh";
"initial" + "10vh" is not valid. You can do it like this:
document.querySelector('#Main').style.height += "10vh";
Good luck!
I was looking to trigger different sections with a variable font based on my mouse movement.
For the first section, everything looks great, but when I tried to trigger the second section, it does not work as I expected since is connected to the first one I guess.
I would need to make the section working independently and in the correct way (to have an idea see section one how react in debug mode)
I was wondering what I have to modify in my Javascript code to make my snippet work with all the sections I want, working independently with their respective variable font interaction. Any ideas?
$('.square').on('mousemove', function(e) {
var x = e.pageX - $(this).offset().left;
var y = e.pageY;
var $tlSquare = $('.division--top.division--left');

var $blSquare = $('.division--bottom.division--left');
var $brSquare = $('.division--bottom.division--right');
var squareWidth = $(this).width(),
squareHeight = $(this).height();
$tlSquare.width(x).height(y);
$trSquare.width(squareWidth - x).height(y);
$blSquare.width(x).height(squareHeight - y);
$brSquare.width(squareWidth - x).height(squareHeight - y);
stretchLetter(false);
});
stretchLetter(false);
$('.square').on('mouseleave', function() {
$('.division').width('50%').height('50%');
$('.letter').css('transform', '');
stretchLetter(false);
});
function stretchLetter(animation) {
$('.letter').each(function() {
var parentWidth = $(this).parent().width();
var parentHeight = $(this).parent().height();
var thisWidth = $(this).width();
var thisHeight = $(this).height();
var widthPercent = parentWidth / thisWidth;
var heightPercent = parentHeight / thisHeight;
var timing = animation == true ? .5 : 0;
TweenMax.to($(this), timing, {
scaleX: widthPercent,
scaleY: heightPercent
})

See working FIDDLE
You had to change the y variable because you were calculating with the offset top of the mouse position inn the document. This is always bigger than the element, so you have to extract the offset top of the element you were scrolling on, to get the right value.
var y = e.pageY - $(this).offset().top;
I have two toggles (toggle-1 and toggle-2) with different contents in a header. I would like to prevent the user to have both toggles active simultaneously (otherwise they overlap).
In the code below I tried to use if statements to hide one of the toggles if the other is already opened but it does not work.
Ideally, what I would like to happen is that if toggle-1 is active and the user clicks on toggle-2, then toggle-1 would come back to its original state and toggle-2 would be now active. The same the other way around.
I am not familiar with JavaScript yet and I'd really appreciate if you could tell me what I have done wrong and how it should be done to have my ideal result
Here's the link to my CodePen if you find it easier:

Several issues.
Please study the code below
too many $(document.ready... and no need to store the result of such a statement
Using a data-attribute and a common class, shortens the code a lot. DRY Don't repeat yourself
I simplified the content containers CSS too
$(function() { // on page load
$('.toggle').on("click", function() { // any of the toggles
const $wrapper = $(this).closest(".wrapper");
const id = $(this).data("id");
$(this).toggleClass('active'); // toggle clicked div
const show = $(this).is(".active"); // is it active after we toggled?
$wrapper
.find(".toggle") // find all toggles
.not(this) // exclude the one we clicked
.removeClass("active"); // remove class
$wrapper.find(".content").hide(); // hide any content divs
$("#" + id).toggle(show); // show the one belonging to the clicked toggle
})
})

Working code:
$(document).ready(function() {
$('.toggle-1').click(function() {
if ($('.toggle-2').hasClass('active')) {
// remove toggle-2 active classes
$('.toggle-2').removeClass('active');
$('.toggle-2-content').removeClass('active');
}
$('.toggle-1').toggleClass('active');
$('.toggle-1-content').toggleClass('active');
});
$('.toggle-2').click(function() {
if ($('.toggle-1').hasClass('active')) {
// remove toggle-1 active classes
$('.toggle-1').removeClass('active');
$('.toggle-1-content').removeClass('active');
}
$('.toggle-2').toggleClass('active');
$('.toggle-2-content').toggleClass('active');
});
});
Here is the link to my working version.
A few things to keep in mind:
You don't need to call $(document).ready() multiple times. There's just no reason to call it multiple times on a single page as the event is only fired once.
You need to keep track of state somehow; hence the if ($('el').hasClass('classname')) syntax. Once you handle that properly, it's easy to ensure that each element is 'reset' to its original state when the other is clicked.
Hope that helps!
toggleClass accepts a second boolean parameter that forces the type of toggle, on or off. More than that you can also target multiple elements with a single jQuery call, so use that to your advantage since the classes applied have the same name.
So you could simplify your code to
$(document).ready(function() {
$('.toggle-1').click(function() {
$('.toggle-1, .toggle-1-content').toggleClass('active');
$('.toggle-2, .toggle-2-content').toggleClass('active', false)
})
$('.toggle-2').click(function() {
$('.toggle-2, .toggle-2-content').toggleClass('active');
$('.toggle-1, .toggle-1-content').toggleClass('active', false)
})
})

You can use the method "removeClass" to remove the active class from the other toggle
var oneToggle = $(document).ready(function() {
$(".toggle-1").click(function() {
$(".toggle-1").toggleClass("active")
$(".toggle-1-content").toggleClass("active")
$(".toggle-2").removeClass("active")
$(".toggle-2-content").removeClass("active")
})
})
var twoToggle = $(document).ready(function() {
$(".toggle-2").click(function() {
$(".toggle-1").removeClass("active")
$(".toggle-1-content").removeClass("active")
$(".toggle-2").toggleClass("active")
$(".toggle-2-content").toggleClass("active")
})
})
I wanted to do a cool menu effect for a website I'm working on. I'm having a div act as the the section for the main content. When the user opens the menu, the main content div will resize and move out of the way, revealing the menu. However, when I do this with the code I have written, it always loses my scrolling place on the page. Is there any way to keep my place on the page when it shrinks and also when it expands back again? Below is what I have. Thank you in advance!

Please take a look at the snippet below. Notice how the overflow property is used.
You have to scroll mock-body-container to keep its scrolling position.
You're scrolling body instead, so when you scale mock-body-container there is nothing to scroll in body and you loose the scrolling position.
function shrinkPage() {
var element = document.getElementById("mock-body");
element.classList.toggle("mock-body-on-burger");
var z = document.getElementById("mock-body-container");
z.classList.toggle("mock-body-container-on-burger");
var x = document.getElementById("body");
x.classList.toggle("body-on-burger");
};
body {
margin: 0;
background:#000;
}
.body-on-burger {
max-width: 100%;
overflow-x:hidden;
}
.mock-body-container{
height:100vh;
overflow:auto;
}
.mock-body-container-on-burger {
height:100vh;
transform: scale(0.4) translate(130%);
}
.mock-body-size-change{
overflow: scroll;
}
.mock-body {
position:relative;
background: #fff;
margin-left: 50px;
}
.container {
position: fixed;
height:50px;
width:50px;
cursor: pointer;
}
.container #icon {
width: 16px;
height: 8px;
position: relative;
margin: 0px auto 0;
top: 40%;
}
.container #icon .bars {
height: 1px;
background: #fff;
}
.myDiv {
height:500px;
}
.one {
background:red;
}
.two {
background:green;
}
.three {
background:blue;
}
<body id="body">
<div class="menu-activator" onclick="shrinkPage()">
<div class="container usd">
<div id="icon">
<div class="bars first"></div>
</div>
</div>
</div>
<div id="mock-body-container" class="mock-body-container">

Once you know the element that was in focus it should be relatively easy. If you need to find which element was last in focus, you can do that with a scroll function. If you need this as well let me know and I will update my answer.
If you know that #mock-body is the last element in focus, just scroll back to it after the resize.
In this example I've used jQuery as it makes this interaction easier, but this can be done (albeit more verbosely) with vanilla JS as well.
$('html, body').animate({
scrollTop: $('#mock-body').offset().top
}, 0); // If you want the animation to be smoother you can increase 0 to a higher number
A simple way to do it is to remember the position of the document scroll and reapply it when you getting back to "normal" view:
let savedScroll;
function shrinkPage() {
let _s = (el) => document.querySelector(el),
s_ = (d) => !d.classList.contains('body-on-burger'),
x = _s('#body'),
element = _s('#mock-body'),
z = _s('#mock-body-container');
if (s_(x)) {
savedScroll = document.documentElement.scrollTop;
}
element.classList.toggle("mock-body-on-burger");
z.classList.toggle("mock-body-container-on-burger");
x.classList.toggle("body-on-burger");
if (s_(x)) {
document.documentElement.scrollTop = savedScroll;
}
};
Check it out:
let savedScroll;
function shrinkPage() {
let _s = (el) => document.querySelector(el),
s_ = (d) => !d.classList.contains('body-on-burger'),
x = _s('#body'),
element = _s('#mock-body'),
z = _s('#mock-body-container');
if (s_(x)) {
savedScroll = document.documentElement.scrollTop;
}
element.classList.toggle("mock-body-on-burger");
z.classList.toggle("mock-body-container-on-burger");
x.classList.toggle("body-on-burger");
if (s_(x)) {
document.documentElement.scrollTop = savedScroll;
}
};
body {
margin: 0;
background: #000;
}
.body-on-burger {
max-width: 100%;
overflow-x: hidden;
}
.mock-body-container {
height: 100vh;
}
.mock-body-container-on-burger {
height: 100vh;
transform: scale(0.4) translate(130%);
overflow: hidden;
}
.mock-body-size-change {
overflow: scroll;
}
.mock-body {
position: relative;
background: #fff;
margin-left: 50px;
}
.container {
position: fixed;
height: 50px;
width: 50px;
cursor: pointer;
}
.container #icon {
width: 16px;
height: 8px;
position: relative;
margin: 0px auto 0;
top: 40%;
}
.container #icon .bars {
height: 1px;
background: #fff;
}
.myDiv {
height: 500px;
}
.one {
background: red;
}
.two {
background: green;
}
.three {
background: blue;
}
<body id="body">
<div class="menu-activator" onclick="shrinkPage()">
<div class="container usd">
<div id="icon">
<div class="bars first"></div>
</div>
</div>
</div>
<div id="mock-body-container" class="mock-body-container">
<div id="mock-body" class="mock-body">
<div class="myDiv one"></div>
<div class="myDiv two"></div>

Legend: _s(el) returns first match of el and s_(d) checks if d has class body-on-burger.
The simple way to do this is to determine the change in height during the resize, and scroll that much.
const heightChange = newHeight - initialHeight;
scrollableDiv.scrollTop = scrollableDiv.scrollTop - heightChange;
In my case I am using a resize method I wrote, so I do this work inside of a window.addEventListener("mousemove", handleResize); when I know the div in actively being resized by the user.
This will still work fine with native html resizable elements, you just need to figure out how/when to listen for resize/drag events accordingly.
I have 3 boxes: kotak1, kotak2, and kotak3.
#kotak1 has the test "COBA AKU"
CSS:
<style>
body {
margin: 0;
padding: 0;
}
#mainCont {
margin: 0 auto;
width: 1024px;
height: 768px;
background-color: #F00;
}
#kotak1{
width: 1024px;
height: 768px;
background-color: #0F9;
text-align: center;
vertical-align: middle;
}
#kotak2{
width: 240px;
height: 768px;
background-color: #666;
float: left;
}
#kotak3{
width: 240px;
height: 768px;
background-color: #03F;
float: right;
}
</style>
HTML:
<body>
<div id="mainCont">
<div id="kotak2"></div>
<div id="kotak3" onmouseout="keluarkotak()"></div>
<div id="kotak1">
COBA AKU
</div>
</div>
</body>
I want to change the text in #kotak1 to "SELESAI TIDUR" when the you mouse out from #kotak3 and enter #kotak2.
Here's a fiddle: http://jsfiddle.net/PZfwT/1
Here's the supporting code, just manage whether you've left three and then when your mouse enters 2 you can change the text of 1. I'd recommend doing this with jQuery, it's easier to manage overall if done that way.
(function() {
var mousedOutThree = false;
window.App = {
kotak2In: function() {
if (mousedOutThree) {
mousedOutThree = false;
document.getElementById("kotak1").innerHTML = "SELESAI TIDUR";
}
},
kotak3Out: function() {
mousedOutThree = true;
}
};
})();
