I am trying to create a div resizer and due to some restrictions, I cannot use jQuery and I am forced to use pure JavaScript for that. In the current state, it works, but it breaks if the div that will have the slider does not have the position set to absolute. Is there a way to solve that issue? Thank you very much.
I am a student learning to write JavaScript/CSS/HTML code and so I am relatively new to this.
const BORDER_SIZE = 4;
const panel = document.getElementById("left_panel");
const StationaryPanel = document.getElementById("right_panel");
const parent = document.getElementById("parent");
const label1 = document.getElementById("lb1");
const label2 = document.getElementById("lb2");
const label3 = document.getElementById("lb3");
let m_pos;
function resize(e) {
const dx = m_pos - e.x;
m_pos = e.x;
lb1.innerHTML = panel.offsetWidth;
lb2.innerHTML = StationaryPanel.offsetWidth;
lb3.innerHTML = parent.offsetWidth;
//lb3.innerHTML = document.body.clientWidth;
panel.style.width = (parseInt(getComputedStyle(panel, '').width) + dx) + "px";
StationaryPanel.style.width = (parent.offsetWidth - panel.offsetWidth) + "px";
//StationaryPanel.style.width = (document.body.clientWidth - panel.offsetWidth) + "px";
}
panel.addEventListener("mousedown", function(e) {
if (e.offsetX < BORDER_SIZE) {
m_pos = e.x;
if (panel.style.width < panel.minWidth || panel.style.width > panel.maxWidth) {
return;
}
document.addEventListener("mousemove", resize, false);
}
}, false);
document.addEventListener("mouseup", function() {
document.removeEventListener("mousemove", resize, false);
}, false);
#left_panel {
position: absolute;
width: 96px;
min-width: 50px;
max-width: 500px;
padding-left: 4px;
height: 100%;

Here is the simplest way you can do it using CSS if that is not an issue here no need to use JS for this feature, it is just an example but it definitely help you on your way.
#MainDiv {
display: flex;
flex-direction: row;
height: 200px;
width: 400px;
border: 1px solid red;
position: relative;
}
#leftDiv {
width: 200px;
border: 1px solid yellow;
}
#rightDiv {
border: 2px solid;
padding: 20px;
width: 300px;
/* you can make this vertical/auto to make resize both ways */
resize: horizontal;
overflow: auto;
}
<div id="MainDiv">
<div id="leftDiv">
Left Div
</div>
<div id="rightDiv">
Right Div
</div>
</div>
Here is it in Javascript:
var h = $('#handle'),
l = $('#left'),
r = $('#right'),
w = $('body').width() - 18;
var isDragging = false;
h.mousedown(function(e) {
isDragging = true;
e.preventDefault();
});
$(document).mouseup(function() {
isDragging = false;
}).mousemove(function(e) {
if (isDragging) {
l.css('width', e.pageX);
r.css('width', w - e.pageX);
}
});
#left,
#right {
border: 1px solid #aaa;
float: left;
height: 100px;
width: 48%;
}
#handle {
background: #000;
float: left;
height: 100px;
margin: 1px;
/* Slider width */
width: 10px;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div id="left"> Left</div>
<div id="handle"></div>
<div id="right">Right</div>

I did a div that is moveable but unfortunetaly the function that let user move the div also block the highlight of the text in the text area behind.
I would like to keep the possibility to move the div and to highlight the text in textarea like I want.
Ps: I already tried to put the addEventListener on varMoveButtonNotesWindow but it's really ncomfortable to use it like that (we need to keep the cursor in the little box, and I dont want the box to be bigger it wouldn't look good).
Here's the code:
var mousePosition;
var offset = [0,0];
var isDown = false;
var varMoveButtonNotesWindow = document.getElementById('moveButtonNotesWindow');
var varNotesWindow = document.getElementById('notesWindow');
varMoveButtonNotesWindow.addEventListener('mousedown', function(e) {
isDown = true;
offset = [
varNotesWindow.offsetLeft - e.clientX,
varNotesWindow.offsetTop - e.clientY
];
}, true);
document.addEventListener('mouseup', function() {
isDown = false;
}, true);
//The bug occurs here
document.addEventListener('mousemove', function(event) {
event.preventDefault();
if (isDown) {
mousePosition = {
x : event.clientX,
y : event.clientY
};
varNotesWindow.style.left = (mousePosition.x + offset[0]) + 'px';
varNotesWindow.style.top = (mousePosition.y + offset[1]) + 'px';
}
}, true);
//so far
function closeNotesWindow() {
varNotesWindow.classList.remove('show');
}
function openNotesWindow() {
windowsModalContainer.classList.remove('show');
varNotesWindow.classList.add('show');
};
.firstTextarea {
height: 300px;
width: 300px;
}
#notesWindow {
display: block;

This can do like but not perfact：
RollBack selection when focus back it.
var mousePosition;
var offset = [0,0];
var isDown = false;
var varMoveButtonNotesWindow = document.getElementById('moveButtonNotesWindow');
var varNotesWindow = document.getElementById('notesWindow');
varMoveButtonNotesWindow.addEventListener('mousedown', function(e) {
isDown = true;
offset = [
varNotesWindow.offsetLeft - e.clientX,
varNotesWindow.offsetTop - e.clientY
];
}, true);
document.addEventListener('mouseup', function() {
isDown = false;
}, true);
//The bug occurs here
document.addEventListener('mousemove', function(event) {
event.preventDefault();
if (isDown) {
mousePosition = {
x : event.clientX,
y : event.clientY
};
varNotesWindow.style.left = (mousePosition.x + offset[0]) + 'px';
varNotesWindow.style.top = (mousePosition.y + offset[1]) + 'px';
}
}, true);
//so far
window.addEventListener('load',function(){

if((lastSelectionStart !== lastSelectionEnd)){
tgItem.focus();
tgItem.setSelectionRange(lastSelectionStart,lastSelectionEnd);
}
}
var docTextareas = document.getElementsByTagName('textarea');
for (var i = 0; i < docTextareas.length; i++) {
docTextareas[i].addEventListener('select', logTextSelection, true);

OK I found it, i just created a div that replace document for the addeventListener.
Ps I set the color to rgba(0, 175, 0, 0.3) just for you to see how it react and work you can obviously change it to 0.
function start() {
varNotesWindow.classList.add('show');
}
var mousePosition;
var offset = [0,0];
var isDown = false;
var varMoveButtonNotesWindow = document.getElementById('moveButtonNotesWindow');
var varNotesWindow = document.getElementById('notesWindow');
const constAlternativeDocumentForMoveButtonsWindow = document.getElementById('alternativeDocumentForMoveButtonsWindowId');
//Start Move Notes Window
varMoveButtonNotesWindow.addEventListener('mousedown', function(e) {
isDown = true;
offset = [
varNotesWindow.offsetLeft - e.clientX,
varNotesWindow.offsetTop - e.clientY
];
constAlternativeDocumentForMoveButtonsWindow.classList.add('use');
}, true);
constAlternativeDocumentForMoveButtonsWindow.addEventListener('mousemove', function(event) {
event.preventDefault();
if (isDown) {
mousePosition = {

};
varNotesWindow.style.left = (mousePosition.x + offset[0]) + 'px';
varNotesWindow.style.top = (mousePosition.y + offset[1]) + 'px';
}
}, true);
constAlternativeDocumentForMoveButtonsWindow.addEventListener('mouseup', function() {

I am new to Javascript and CSS. I have a div that will contain an image. The below code, I pieced it together after watching some YouTube videos and going over some documentation, however I am sure that this is not the right code.
https://jsfiddle.net/0hp97a6k/
* {
margin: 0;
padding: 0;
}
body {
background-color: powderblue;
height: 2000px;
padding: 0 0;
}
div {
margin: 0;
}
.headerspace {
width: 100%;
height: 20px;
background-color: white;
}
.header {
width: 100%;
height: 300px;
background-color: maroon;
display: flex;
}
.logo {
width: 200px;
height: 200px;
background-color: red;
margin-top: 50px;
margin-left: 50px;
}
<!DOCTYPE html>
<html>
<head>
<link rel="stylesheet" href="styles.css">
</head>
<body>
<div class="headerspace"></div>
<div class="header">
<div class="logo" id="logoid">
</div>
</div>
<script type="text/javascript">
let logo = document.getElementById("logoid");
window.addEventListener('scroll', function() {
var value = window.scrollY;
logo.style.marginleft = value * 0.5 + 'px';
})
</script>
</body>
</html>
How do I set the left margin based on scroll?
Also can scroll based properties be applied to two margins, say top and right at the same time?
marginleft should be marginLeft in your javascript
<script type="text/javascript">
let logo = document.getElementById("logoid");
window.addEventListener('scroll', function(){
var value = window.scrollY;
logo.style.marginLeft = value * 0.5 + 'px';
})
</script>
And then if you want to edit the left and top you can do the following
<script type="text/javascript">
let logo = document.getElementById("logoid");
window.addEventListener('scroll', function(){
var value = window.scrollY;
logo.style.marginLeft = value * 0.5 + 'px';
logo.style.marginTop = value * 0.5 + 'px';
})
</script>
To make sure the logo element goes back where it started you should edit the css like this
* {
margin: 0;
padding: 0;
}
body {
background-color: powderblue;
height: 2000px;
padding: 0 0;
}
div{
margin: 0;
}
.headerspace{
width: 100%;
height: 20px;
background-color: white;
}
.header{
width: 100%;
height: 300px;
background-color: maroon;
display: flex;
padding-top: 50px;
padding-left: 50px;
}
.logo{
width: 200px;
height: 200px;
background-color: red;
}
I have removed the margin from .logo because that will be overwritten and added those values as padding to the parent (.header)
I'm having a hard time figuring out why the code below doesn't work as expected.
What I'm trying to achieve is same functionality with position:sticky whereas when the scrolled reaches the top of the #second-header then fixes its position below the #header which is also fixed, however, the height of the #header is unknown which is I believe can be calculated using the function outerHeight(true) on JQuery.
Then after reaching out to the bottom of the #second-header-container, remove the fixed position of #second-header turning it back to normal position.
Due to browser compatibility issues and other customization, I cannot simply use the position:sticky of css.
It looks like my logic is wrong, and I need help.
jQuery(document).ready(function(){
var $document = jQuery(document);
var header = jQuery('#header');
var second_header = jQuery('#second-header-container').find('#second-header');
var second_header_container = jQuery('#second-header-container');
var second_header_offset = second_header.offset().top;
var second_header_container_offset = second_header_container.offset().top;
jQuery(window).scroll(function(){
var top_margin = header.outerHeight(true);
var second_header_height = second_header.outerHeight(true);
var second_header_container_height = second_header_container.outerHeight(true);
if( jQuery(window).scrollTop() > (second_header_offset - second_header_height) && jQuery(window).scrollTop() < second_header_container_height) {
second_header.addClass('fixer');
second_header.css({position:'fixed', top:top_margin, 'z-index':'999999'});
} else {
second_header.removeClass('fixer');
second_header.css({position:'relative', top:'0px', 'z-index':'0'});
}
});
});
*{

padding: 0;
margin: 0;

To achieve this you need first check if the scroll height is near the second div header and within the height of the second div. Then add a class that make it stick below the main header. I have created a sticky class and added it while scrolling conditions are met.
Please check below code
jQuery(document).ready(function() {
var headerHeight = $('#header').outerHeight(true);
var secondHeaderContainer = $('#second-header-container');
const secondHeaderTopPos = secondHeaderContainer.offset().top;
const secondHeaderContainerHeight = $(secondHeaderContainer).height();
$(window).scroll(function() {
const scrollTop = $(this).scrollTop();
const secondContainerHeightEnd = secondHeaderContainerHeight + secondHeaderTopPos - $('#second-header').height() - headerHeight;
if (((secondHeaderTopPos - headerHeight) <= scrollTop) && (secondContainerHeightEnd >= scrollTop)) {
$('#second-header').addClass('sticky').css('top', headerHeight);
} else {
$('#second-header').removeClass('sticky');
}
});
});

My Code:
window.addEventListener('scroll', scrollWhere);
function scrollWhere(e) {
var windowScroll = $(window).scrollTop();
var idScroll = $('.me').offset().top;
var height = $("#half-who").height();
if (windowScroll > idScroll) {
$('.me').addClass('me-fixed');
} else {
$('.me').removeClass('me-fixed');
}
}
I want to add a class when the scroll is past a certain point and remove it when is smaller than that certain point.
Get your idScroll value outside scrollWhere function as because it re-initiate calculation again and again and returns different values each time as because it has a fixed position. check below snippet for reference.
window.addEventListener('scroll', scrollWhere);
var idScroll = $('.me').offset().top;
function scrollWhere(e) {
var windowScroll = $(window).scrollTop();
//var height = $("#half-who").height();
if (windowScroll > idScroll) {
$('.me').addClass('me-fixed');
} else {
$('.me').removeClass('me-fixed');
}
}
.container {
height: 300vh;
width: 100%;
background-color: grey;
padding: 0;
margin: 0;
}
.content {
height: 100px;
width: 100%;
background-color: cyan;
}
.me {
height: 50px;
width: 100%;
background-color: red;
}
.me-fixed {
position: fixed;
top: 0;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="container">
<div class="content"></div>
<div class="me"></div>
</div>
Here's a simple example to add a class when scroll passing a certain point. Hope you can get an idea. >>> JSFiddle
$(window).scroll(function(){
var winH = $(window).scrollTop();
var ruler = $('.ruler').position().top;
if(ruler < winH){
$('.nav').addClass('me-fixed');
}
else{
$('.nav').removeClass('me-fixed');
}
});
body{
height: 1500px;
}
.nav{
height: 50px;
background: #a1bfbe;
color: #000;
width: 100%;
position: relative;
top: 250px;
text-align: center;
}
.nav.me-fixed{
background: #c2debf;
}
p{
font-size: 20px;
display: none;
}
.me-fixed p{
display: block;
}
.ruler{
position: fixed;
top: 150px;
border-bottom: 1px solid red;
width: 100%;
}

Also if you can provide the html and css structure, it will be easy to identify the issue.
I want to make a draggle splitter between 2 panels. The following is a working version.
Now, I want to make the width of handle as thin as possible (less than 0.1px?), so there is no way to make the width (appear) smaller than 1px?
Additionally, when the splitter is thin, it is hard to select by the mouse. Is there a way to make a splitter easy to grab?
Taking JSBin as example, how did they manage to realise the splitters among the panels?
(function($) {
$.fn.drags = function(opt) {
opt = $.extend({
handle: "",
cursor: "ew-resize",
min: 10
}, opt);
if (opt.handle === "") {

If you'd like the handle to appear thinner try applying a negative value to the right "col" e.g. margin-left: -2px; so it overlaps the left "col" border on the left of it. I don't think you can make the width "appear" as 0.1px. Firefox is the only browser that renders such value. (https://css-tricks.com/forums/topic/0-1px-borders/)
.flex-box .col:last-child {
margin-left: -2px;
}
//raise handle layer to top
.handle {
.....
z-index: 9999;
}
Hope this helps...
*Edit:
This is the closest I could get to your request:
.flex-box {
display: flex;
width: 100%;
margin: 0;
height: 300px;
}
.flex-box .col {
border: 1px solid grey;
flex: 0.33;
padding: 12px;
overflow-y: auto;
overflow-x: hide;
}
.flex-box .col:last-child {
margin-left: -6px;
}
.handle {
width: 5px;
text-align: center;
transition: all ease-in 0.1s;
z-index: 999;
overflow: visible;
}
.handle-inner{
width: 5px;
height: 100%;
position: relative;
margin-left: -10px;
}
.draggable {
background: grey;
}
