I was trying to move the divs (here it's question number) based on the prev and next button. So that the selected question is always visible on screen.
Here is the demo : http://jsfiddle.net/arunslb123/trxe4n3u/12/
Screen :
click and question number and click prev or next button to understand my issue.
My code :
$("#next")
.click(function () {
$(".c.current-question")
.each(function () {
var divIdx = $(this)
.attr('id');
var scrollTo = $('#' + divIdx)
.position()
.left;
$("#scrollquestion")
.animate({
'scrollLeft': scrollTo
}, 800);
});
});
$("#prev")
.click(function () {
$(".c.current-question")
.each(function () {
var divIdx = $(this)
.attr('id');
var scrollTo = $('#' + divIdx)
.position()
.left;
$("#scrollquestion")
.animate({
'scrollLeft': -scrollTo
}, 800);
});
});
Using scrollLeft is a bit tricky. I did a small redo of your use-case based on positioning and then moving it based on left of the container. The tricky part is to reliably calculate the negative position when scrolled to the extreme right. Also, need to take into account the widths and margins.
Check the below snippet:
var $wrap = $("#numWrap"), $strip = $("#strip"),
$leftArrow = $(".wrapper > .arrows").first(),
wrapWidth = $wrap.width() + $leftArrow.width(),
margin = 10;
fill(20); select($(".numberItem").first());
$strip.on("click", ".numberItem", function() { select($(this)); });
function select($elem) {
$(".numberItem").removeClass("selected");
$elem.addClass("visited").addClass("selected");
focus($elem[0]);
}
function focus(elem) {
var stripPos = $strip.position(),
numPos = $(elem).offset(),
elemWidth = $(elem).width() + margin,
numRight = numPos.left + elemWidth;
if (numRight > wrapWidth) {
$strip.css({"left": stripPos.left - elemWidth});
}
if (numPos.left < (margin + $leftArrow.width())) {
$strip.css({"left": stripPos.left + elemWidth});
}
}
$(".wrapper").on("click", "a.arrow", function() {
var stripPos = $strip.position();
if (this.id == "lft") {
$strip.css({"left": stripPos.left + (wrapWidth / 2)});
} else {
$strip.css({"left": stripPos.left - (wrapWidth / 2)});
}
});
$(".controls").on("click", "a.arrow", function() {
var $sel = $(".selected"), numPos, $sel, elemWidth;
$elem = $sel.length > 0 ? $sel.first() : $(".numberItem").first();
if (this.id == "lft") {
$sel = $elem.prev().length > 0 ? $elem.prev() : $elem;
select($sel);
} else {
$sel = $elem.next().length > 0 ? $elem.next() : $elem;
select($sel);
}
numPos = $sel.offset(); elemWidth = $sel.width() + margin;
numRight = numPos.left + elemWidth;
if (numPos.left > wrapWidth) {
$strip.css({"left": -($sel.text()) * $sel.width() });
}
if (numRight < 0) {
$strip.css({"left": +($sel.text()) * $sel.width() });
}
});
function fill(num){
for (var i = 1; i <= num; i++) {
var $d = $("<a href='#' class='numberItem'>" + i + "</a>");
$strip.append($d);
}
}

Explanation:
Using absolute positioning on the number container, which is nested to get 100% width.
Markup:
<div class="wrapper">
<div class="arrows"><a id="lft" class="arrow" href="#">〈</a></div>
<div id="numWrap" class="numWrap">
<div id="strip" class="strip"></div> <!-- nesting here -->
</div>
<div class="arrows"><a id="rgt" class="arrow" href="#">〉</a></div>
</div>
CSS:
div.wrapper {
background-color: #ddd; width: 100vw; height: 64px;
clear: both; overflow: hidden; margin-top: 16px;
}
div.arrows {
float: left; width: 10%; min-width: 24px; height: 64px; line-height: 64px;
text-align: center; vertical-align: middle; overflow: hidden;
}
div.numWrap {
float: left; height: 64px; line-height: 64px;
width: 80%; vertical-align: middle;
overflow: hidden; position: relative; /* relatively positioned */
}
div.strip {
position: absolute; left: 0px; /* absolutely positioned */
width: auto; white-space: nowrap;
transition: left 1s; /* instead of jquery animate */
}
With this structure, we can now use left to control the scrolling.
For partially obscured numbers, try to gently focus-in (nudge into view) a number which is partially obscured. This can be done by checking the position relative to parent and adding the width/margin to it and also accounting for width of the left arrow (it might peep thru).
Javascript:
function focus(elem) {
var stripPos = $strip.position(),
numPos = $(elem).offset(),
elemWidth = $(elem).width() + margin,
numRight = numPos.left + elemWidth;
// if it is towards right side, nudge it back inside
if (numRight > wrapWidth) {
$strip.css({"left": stripPos.left - elemWidth});
}
// if it is towards left side, nudge it back inside
if (numPos.left < (margin + $leftArrow.width())) {
$strip.css({"left": stripPos.left + elemWidth});
}
}
Once the user has scrolled the list too far and then tries to click on previous / next buttons to select a question, then we need to move the entire container upto the selected number. We can easily do this by multiplying the question number with element width and then changing the left in positive (if towards right) or in negative (if towards left).
Javascript:
// if left of element is more than the width of parent
if (numPos.left > wrapWidth) {
$strip.css({"left": -($sel.text()) * $sel.width() });
}
// if right of element is less than 0 i.e. starting position
if (numRight < 0) {
$strip.css({"left": +($sel.text()) * $sel.width() });
}
Here is a fiddle to play with: http://jsfiddle.net/abhitalks/aw166qhx/
You will need to further adapt it to your use-case, but you get the idea.

I am using the following HTML/Javascipt code to make the classic percentage bar.
function update() {
var element = document.getElementById("myprogressBar");
var width = 1;
var identity = setInterval(scene, 10);
function scene() {
if (width >= 70) {
clearInterval(identity);
} else {
width++;
element.style.width = width + '%';
element.innerHTML = width * 1 + '%';
}
}
}
#Progress_Status {
width: 50%;
background-color: #ddd;
}
#myprogressBar {
width: 1%;
height: 35px;
background-color: #4CAF50;

line-height: 32px;

What I would like to obtain and I am trying to achieve with .innerHTML is the following situation
The vertical line has to appear at the same level of the specified percentage.
For the vertical bar I used an added div nested inside the #Progress_Status container. It's styled to be absolute positioned and to change its offset in % in sync with the progress bar width.
For it to work, its container was set to position:relative as the reference frame.
function update() {
//fetches the vertical bar elements
var vbar = document.querySelector("#Progress_Status .percverticalbar");
var element = document.getElementById("myprogressBar");
var width = 1;
var identity = setInterval(scene, 10);
function scene() {
if (width >= 70) {
clearInterval(identity);
} else {
width++;
//updates the left offset of the vertical bar
vbar.style.left = `${width}%`;
element.style.width = width + '%';
element.innerHTML = width * 1 + '%';
}
}
}

You could just add an :after pseudo element and add the following styles to it. Keep in mind that the parent, in the case #myprogressBar should be relatively positioned.
#myprogressBar {
width: 1%;
height: 35px;
background-color: #4CAF50;
text-align: center;
line-height: 32px;
color: black;
position: relative;
}
#myprogressBar:after {
width: 5px;
height: 80px;
background: #333;
content: '';
position: absolute;
right: -5px;
top: 50%;
transform: translateY(-50%);
border-radius: 5px;
}
I am resizing and positioning a box using the mousemove event. Those. i change transform translate and width (height) with pageX (pageY). But due to the fact that the mouse event mousemove does not always have time to be processed (for example, if you move the mouse quickly) or does not have time to read conditions, the block goes out of bounds.
Question: what do I need to do in this case so that the block does not go beyond the boundaries?
This is how it looks roughly. Those. in this example, the second_block is outside the first_block (500px), i.e. it does not have time to read the condition. How should this issue be resolved? Also for convenience https://jsfiddle.net/ManuOP/t1r4szdx/3/

let point = document.getElementById('point');
function change_second_block() {
if(second_block.clientWidth < 500) {
second_block.style.width = `${start_x + event.pageX}px`;
}
}
point.addEventListener('mousedown', (event) => {
window.start_x = second_block.clientWidth - event.pageX;
document.addEventListener('mousemove', change_second_block);
});
You could just test the new width and if it's too large then constrain it to be no more than the maximum.
This snippet does this for the x direction and forces it to remain at or below 500px.
"use strict";
let second_block = document.getElementById('second_block');
let point = document.getElementById('point');
function change_second_block() {
if (second_block.clientWidth < 500) {
second_block.style.width = (start_x + event.pageX) < 500 ? `${start_x + event.pageX}px` : '500px';
}
}
point.addEventListener('mousedown', (event) => {
window.start_x = second_block.clientWidth - event.pageX;
document.addEventListener('mousemove', change_second_block);
});

You can work around this issue if the size of the change in the item is above a certain limit, or by checking the limit and stopping the update. I prevented the overflow caused by rapid mouse movement by updating its code as follows:
function change_second_block()
{
console.log("Event.PageX: " + event.pageX);
if(event.pageX < 500 )
{
if(second_block.clientWidth < 500)
{
second_block.style.width = `${start_x + event.pageX}px`;
}
}
}

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'});

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');
}
});
});

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 === "") {
var $el = this;
} else {
var $el = this.find(opt.handle);
}
var priorCursor = $('body').css('cursor');
return $el.css('cursor', opt.cursor).on("mousedown", function(e) {
priorCursor = $('body').css('cursor');
$('body').css('cursor', opt.cursor);
if (opt.handle === "") {
var $drag = $(this).addClass('draggable');
} else {
var $drag = $(this).addClass('active-handle').parent().addClass('draggable');
}
var z_idx = $drag.css('z-index'),
drg_h = $drag.outerHeight(),
drg_w = $drag.outerWidth(),
pos_y = $drag.offset().top + drg_h - e.pageY,
pos_x = $drag.offset().left + drg_w - e.pageX;
var mouseMove = function(e) {
var prev = $('.draggable').prev();
var next = $('.draggable').next();
var total = prev.outerWidth() + next.outerWidth();
var totalPercentage = parseFloat(prev.css('flex')) + parseFloat(next.css('flex'));
var offset = prev.offset();
if(offset){
var leftPercentage = ((e.pageX - offset.left - drg_w / 2) / total) * totalPercentage;
var rightPercentage = totalPercentage - leftPercentage;
if (leftPercentage * 100 < opt.min || rightPercentage * 100 < opt.min) {
return;
}
prev.css('flex', leftPercentage.toString());
next.css('flex', rightPercentage.toString());
}
}
$drag.css('z-index', 1000).parent().on("mousemove", mouseMove).on("mouseup", function() {
$(this).off("mousemove", mouseMove).off("mouseup");
$('body').css('cursor', priorCursor);
$('.draggable').removeClass('draggable').css('z-index', z_idx);
});
e.preventDefault(); // disable selection
});
}
})(jQuery);

<div class="handle"></div>
<div class="col">

</div>
</div>
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...

z-index: 0;
}
#box {
margin: 0 auto;
height: 100px;
width: 100px;
background-color: red;
display: none;
border-radius: 50px;
position: relative;
z-index: 1;
}
h1 {
margin: 15px 0 0 0;
}
#directions {
margin: 0;
padding: 5px;
font-size: 0.8em;
}
#scoreT, #scoreC {
font-weight: bold;
margin: 10px 50px 0 0;
}
#tScore, #cScore {
font-weight: normal;
}
h1, #directions, #scoreT, #scoreC {
width: 100%;
text-align: center;
}
And lastly, the javascript function for random position:
//Get random position
function getRandomPos() {
var pos = Math.floor((Math.random() * 500) + 1);
console.log("POS: " + pos + "px");
return pos + "px";
}
Which I call within a timeout method:
setTimeout(function() {
createdTime = Date.now();
console.log("make box: " + createdTime);
document.getElementById("box").style.top=getRandomPos();
document.getElementById("box").style.left=getRandomPos();
document.getElementById("box").style.backgroundColor=getRandomColor();
document.getElementById("box").style.borderRadius=getRandomShape();
document.getElementById("box").style.display="block";
}, rTime);
I'm not very skilled in positioning and I can't seem to get these two divs to align so that the #box div can recognize the size of the #boxBorder div and stay within those limits. Any help would be appreciated!
Couple things wrong here:
You need the box div nested inside the borderBox div if you want to use the relative positioning.
<div id="boxBorder">
<div id="box"></div>
</div>
The randomPos function needs to take into account the size of the box, so only multiply by 400 instead of 500.
function getRandomPos() {
var pos = Math.floor((Math.random() * 400));
return pos + "px";
}
Set the style to inline-block, not block for the box.
Use setInterval instead of setTimeout to have it repeat.
var rTime = 1000;
function getRandomPos() {
var pos = Math.floor((Math.random() * 400));
console.log("POS: " + pos + "px");
return pos + "px";
}
function getRandomColor() {
return ['#bf616a', '#d08770', '#ebcb8b', '#a3be8c', '#96b5b4', '#8fa1b3', '#b48ead'][(Math.floor(Math.random() * 7))];
}
function randomizeBox() {
createdTime = Date.now();
console.log("make box: " + createdTime);
document.getElementById("box").style.top = getRandomPos();
document.getElementById("box").style.left = getRandomPos();
document.getElementById("box").style.backgroundColor = getRandomColor();
}
setInterval(randomizeBox, rTime);
