When you click on the icon, it becomes black. What can I do to make the icon that was clicked (there may be several of them) black after refreshing the page? I was planning to do this at localStorage.
Be specific to your elements, add ids so that we can specify which item was active.
example.
add id to your item header.
<div id='peru' class="places-item-header-add">
and when the window is loaded check the value in the localstorage and update the item class.
var addBtn = document.querySelectorAll('.places-item-header-add');
var items = JSON.parse(localStorage.getItem('selected_items')) || {};
for (i = 0; i < addBtn.length; ++i) {
if (items[addBtn[i].id]) {
addBtn[i].classList.add('added');
}
addBtn[i].addEventListener('click', function() {
this.classList.toggle('added');
if (this.classList.contains('added')) {
items[this.id] = true;
} else {
items[this.id] = false;
}
localStorage.setItem('selected_items', JSON.stringify(items));
})
}

I can't figure out why I'm getting this little bit of green when the window is an odd number of pixels wide. I think it has something to do with sub-pixel rendering, but I'm just not sure where the green is coming from. It's just the 2nd div too which is weird.
I have some script that is animating the BG of this div. I'm sure this is part of the issue, but I can't figure out why it's only happening to my 2nd div.
I tried to manually set the width of this div, but I was hoping it would be responsive and scale with the window size.
let currentStage = 1
function performAction(selectedStage) {
currentStage = selectedStage
let stages = document.body.getElementsByClassName('stage-flow-item')
let stageLines = document.body.getElementsByClassName('stage-flow-line')
console.log("selectedStage: " + selectedStage)
for (let stage of stages) {
if (stage.id > currentStage) {
stage.classList.remove('completed')
stage.classList.add('active')
} else {
stage.classList.remove('active')
stage.classList.add('completed')
}
}
for (let stageLine of stageLines) {
if (stageLine.id > currentStage) {
stageLine.classList.remove('lineCompleted')
stageLine.classList.add('lineActive')

</div>
I'm not sure if this is on the right track, but I'd eliminate the odd 100vw width on the connectors and instead make them flex. I'd then remove the 200% background size multiplier. By setting the gradient points to 100% the problem is gone. I really don't know if this covers your use case, though.
I converted from background gradient to a pseudo-element solution for the color transition. I think it's simpler. You'd probably have to use CSS animations (as opposed to simple transitions) to make it work otherwise. Of course, you could apply the same principle to the stage items as well, implementing a delay to crate a consistent animation across the item and the line.
Note that duplicated ID values are invalid in HTML. They must be unique. I've refactored to use data attributes instead and an event listener instead of inline JavaScript.

I write the name of the task, then press the "Add" button, the item appears, and next to it the "Finish" button. When I press Finish, the item appears in the To Do section, and next to the item, the Notes button. When I press the notes button, the text area appears and disappears, and in the text area there is an edit button. When I click on it I can type a comment inside the text area, and by pressing the save button the edit is locked into the problematic text area? When I add more than one element the entire text area takes the same as the first comment and I want each element to be stable writing the text area so I can modify the comment in any element without affecting the rest
I'm just starting with Javascript and I made this popup code, and I was wondering if there's another code with the same result or a way of optimizing the Javascript.
The code must make the popup appear when one of the options is clicked and disappear when the click is somewhere else.
Popup code
var activePopup;
document.querySelectorAll('[hasPopup]').forEach((popupParent) => {
popupParent.addEventListener('click', e => {
if (popupParent != activePopup && activePopup != null) {
activePopup.querySelector('[popupContent]').style.display = 'none';
}
window.addEventListener('click', hasClicked => {
let isOnPopup = false;
hasClicked.path.forEach((event) => {
if (event == popupParent) {
isOnPopup = true;
}
})
if (isOnPopup == false){
popupParent.querySelector('[popupContent]').style.display = 'none';
}
})
popupParent.querySelector('[popupContent]').style.display = 'block';
activePopup = popupParent;
})
});
This will do all that you require, but in a much shorter form
puc=document.querySelectorAll("[popupContent]"); // popup divs ...
document.querySelector(".nav-bar__element").onclick=ev=>{
// in case the user clicked on the inner span and not the div:
const pel=[...ev.path].find(e=>e.hasAttribute&&e.hasAttribute("hasPopup"))
if (pel) {
const el=pel.querySelector("[popupContent]");
puc.forEach(d=>d.style.display=d===el?"block":"none")

It worked for me this way:
HTML code
<div class="invalid-chars-alert-close-btn" onclick="document.getElementById('invalidChars-1').classList.toggle('active');">x</div>
JS: code inside if invalid characters written in my form then:
document.getElementById("invalidChars-1").classList.toggle("active");

Flex elements ignore percent padding in Firefox
(4 answers)
Closed 4 years ago.
In my example code, please click on the Generate Content button in order to understand the issue.
Once you click on the button, you can see all of the flex items(.each-result) generate. They are almost completely wrapped by the div/flexbox (.result-container), indicated by the blue dotted border. If I remove the margins from flex-items, it fits perfectly into the div. However, when I add the margins, the parent div (ie. the flexbox) doesn't expand to it's full width; it remains the same width as when there was no margin.
Is there anyway to change this so that the div expands when adding margin?
const leftArrow = document.querySelector('#left-arrow');
const rightArrow = document.querySelector('#right-arrow');
const rootDiv = document.querySelector('#root');
const generateButton = document.querySelector("#button-generate");
var navMargin = '';
let rootContainerWidth = window.getComputedStyle(rootDiv, null).getPropertyValue("width");
console.log(`Window size onload: ${rootContainerWidth}`);
window.addEventListener('resize', () => {
rootContainerWidth = window.getComputedStyle(rootDiv, null).getPropertyValue("width");
console.log(`The new window size is ${rootContainerWidth}`);

If the margin can be a fixed value (instead of a percent), we can calc() the width of the element to account for the margin. For example, if we wanted a margin of 20px we'd do the following on the .each-result elements:
.each-result {
width: calc(10% + 20px);
margin: 0 20px;
}
Here's the working demo:
const leftArrow = document.querySelector('#left-arrow');
const rightArrow = document.querySelector('#right-arrow');
const rootDiv = document.querySelector('#root');
const generateButton = document.querySelector("#button-generate");
var navMargin = '';
let rootContainerWidth = window.getComputedStyle(rootDiv, null).getPropertyValue("width");
console.log(`Window size onload: ${rootContainerWidth}`);
window.addEventListener('resize', () => {
rootContainerWidth = window.getComputedStyle(rootDiv, null).getPropertyValue("width");
console.log(`The new window size is ${rootContainerWidth}`);
})
//This code basically generates the content within the div
generateButton.addEventListener("click", () => {
for (let i = 0; i < 10; i++) {
const newDiv = document.createElement("div");
newDiv.classList.add("each-result");
newDiv.appendChild(addImg("https://uk.usembassy.gov/wp-content/uploads/sites/16/please_read_icon_150x150.jpg"));
rootDiv.appendChild(newDiv);
}
rootDiv.firstElementChild.classList.add('nav-margin');
navMargin = document.querySelector('.nav-margin');
});
//These enable the arrow to scroll through the dynamically generated content
// function navArrow () {

If I have more than one image in a div wrapper. I want to add overlay on image when user hover over the image. I am trying to do using code shown below.
for(var i=0; i<document.getElementsByTagName('img').length; i++) {
document.getElementsByTagName('img')[i].addEventListener('mouseover', function(event){
let elementExists = document.getElementById('wrapper');
let Center = document.createElement('div');
let Text = document.createElement('div');
if (!elementExists) {
let Wrapper = document.createElement('div');
let parentElement = event.currentTarget.parentElement;
Wrapper.classList.add('Wrapper');
Wrapper.id = 'wrapper';
Center.classList.add('Center');
Text.innerHTML = "Sample text";
parentElement.appendChild(Wrapper);
Wrapper.appendChild(Center);
Center.appendChild(Text);
Wrapper.addEventListener('mouseout', function(event){
if (document.getElementById('wrapper')) {
document.getElementById('wrapper').remove();
}
});
}
});
}
.col-md-6 {
width: 375px;
height: 211px;
margin: 20px;
position: relative;
}
.Wrapper {
display: table;
position: absolute;
background-color: rgba(0, 0, 0, 0.5);
height: 100% !important;
width: 100%;
text-align: center;
z-index: 1000;
font-family: arial;
color: #fff;
top: 0;
}
.Center {
display: table-cell;
vertical-align: middle;
}
<div class="col-md-6">
<a href="#">
<img src="https://www.blog.google/static/blog/images/google-200x200.7714256da16f.png" />
</a>

Every time I hover on first image, code just works fine. But when I hover on 2nd image it adds overlay on 1st image only.(It should add overlay on second image) I tried to debug the code and let parentElement = event.currentTarget.parentElement; is showing the a href only.
NOTE: I came to know its because I am giving position: absolute to Wrapper. I only want to make changes in JavaScript file and at max to css.
Please let me know if you found error in the code.
It's simply a css problem. Just add this to what you currently have:
a {
position: relative;
display: inline-block;
}
.Wrapper {
display: inline-block;
left: 0;
}
.Center {
display: flex;
justify-content: center;
flex-direction: column;
text-align: center;
height: 100%;
}
Also I removed the final Text div and added its text to the Center div, as it triggered the mouseout event and made it flicker.
for(var i=0; i<document.getElementsByTagName('img').length; i++) {
document.getElementsByTagName('img')[i].addEventListener('mouseover', function(event){
let elementExists = document.getElementById('wrapper');
let Center = document.createElement('div');
if (!elementExists) {
let Wrapper = document.createElement('div');
let parentElement = event.currentTarget.parentElement;
Wrapper.classList.add('Wrapper');
Wrapper.id = 'wrapper';
Center.classList.add('Center');
Center.innerHTML = "Sample text";
parentElement.appendChild(Wrapper);
Wrapper.appendChild(Center);
Wrapper.addEventListener('mouseout', function(event){
if (document.getElementById('wrapper')) {
document.getElementById('wrapper').remove();
}
});
}
});
}
