Click outside of element to hide element

My code does this: when element .pencil is clicked on, it toggles the hidden element .pencilpanel. When clicked outside of this .test element (there are two .test elements), then this .pencilpanel should hide.
However, my problems are that:
1) When the second .test element is clicked on, the first .test element remains visible when it should be hidden. And,
2) When the first .pencil element is clicked on, and its corresponding .pencilpanel is also clicked on, it will hide .pencilpanel, when it's supposed to remain visible. Any element that is currently visible within .test, and if clicked on, should not be hidden, unless that clicked on element lies outside of the current .test element.
So I'm not getting why when a click is made on .pencilpanel, it hides it on this line if(!$(this).closest('.test').length && $('.pencilpanel').is(":visible")) {. And the fact that the first .pencilpanel remains visible when it should be hidden whenever another .pencil is clicked on. This is my code:
$(document).ready(function () {
$('.pencil').on('click', function (event) {
event.stopPropagation();
$(this).parent(".btsdiv").next(".fcmdiv").children(".pencilpanel").toggleClass("displayblock");
});
});
$(document).ready(function () {
$(document).click(function () {
if (!$(this).closest('.test').length && $('.pencilpanel').is(":visible")) {
$('.pencilpanel').removeClass("displayblock");
}
});
});
.pencilpanel {
display: none;
}
.displayblock {
display: block;
}

You can use the document.activeElement to check before you close the panels. Please find the modified code.
$(document).ready(function() {
$('.pencil').on('click', function(event) {
event.stopPropagation();
closePanel();
$(this).closest(".test").find(".pencilpanel").toggleClass("displayblock");
});
$(document).on("click", function() {
if (document.activeElement.tagName != 'TEXTAREA')
closePanel();
});
});
function closePanel() {
$('.pencilpanel').removeClass("displayblock");
}
.pencilpanel {
display: none;

.displayblock {
display: block;

Vue.js - Add delete button on hover and delete it on button press

I have the below data coming from another server which is not in my control and when displaying it in the browser I have to provide a solution to
1) Show delete button for the class childElement on hover
2) Click on delete button and delete that childElement div
Is there any way I can do it using CSS/JS or Vuejs ( Dynamically adding Delete button on hover and delete the element on button click) ? Thank You
.childElement {
width:100px;
height:100px;
background-color:#f3f3f3;
margin-top:10px;
padding:10px;
}
<div id="videos">
<div class="childElement">
first div
</div>
<div class="childElement">
second div
</div>
<div class="childElement">
third div
</div>
</div>

Your work basically boils down to some script that will find all the elements and auto append elements with listeners.
const childElements = document.querySelectorAll('.childElement');
childElements.forEach(childElement => {
// create button for each childElement
const deleteButton = document.createElement('button');
deleteButton.setAttribute('hidden', '');
deleteButton.innerText = "Click to delete";
// append button to the childElement
childElement.appendChild(deleteButton);
// add event listeners
childElement.addEventListener('mouseenter', event => {
deleteButton.removeAttribute('hidden');
});
childElement.addEventListener('mouseleave', event => {
deleteButton.setAttribute('hidden', '');
});
deleteButton.addEventListener('click', event => {
childElement.setAttribute('hidden', '');
});
});
.childElement {
width: 100px;
height: 100px;
background-color: #f3f3f3;
margin-top: 10px;
padding: 10px;
}
<div id="videos">
<div class="childElement">
first div
</div>
<div class="childElement">
second div
</div>
<div class="childElement">
third div
</div>
</div>

You could add an array to your data object called childDivs and which item inside that array contains a boolean showBtn intilially its value is false and the text to be shown inside the div element
UPDATE :
the above described logic could be useful when you could control the data in front-end, but according to the OP's use case, we could add the script given by #GenericUser inside the mounted hook.
new Vue({
el: '#app',
data() {
return {
childDivs: [{
text: 'First',
showBtn: false
},
{
text: 'Second',
showBtn: false
},
{
text: 'Third',
showBtn: false
}
]
}
},
methods: {
remove(i) {
this.childDivs.splice(i, 1)
}
},
mounted() {
const childElements = document.querySelectorAll('.childElement');
childElements.forEach(childElement => {
const deleteButton = document.createElement('button');
deleteButton.setAttribute('hidden', '');
deleteButton.innerText = "delete";
deleteButton.classList.add("btn")
deleteButton.classList.add("btn-danger")
childElement.appendChild(deleteButton);
childElement.addEventListener('mouseenter', event => {
deleteButton.removeAttribute('hidden');
});
childElement.addEventListener('mouseleave', event => {
deleteButton.setAttribute('hidden', '');
});
deleteButton.addEventListener('click', event => {
childElement.setAttribute('hidden', '');
});
});
}
})
.childElement {
width: 100px;
height: 100px;
background-color: #f3f3f3;
margin-top: 10px;
padding: 10px;
}

Try this code
also use jquery to you project
here like this
<script
src="https://code.jquery.com/jquery-3.3.1.min.js"
integrity="sha256-FgpCb/KJQlLNfOu91ta32o/NMZxltwRo8QtmkMRdAu8="
crossorigin="anonymous"></script>
<div id="videos">
<div class="childElement" id="divOne" >
<div id="delete">X</div>
first div
</div>
<div class="childElement">
second div
</div>
<div class="childElement">
third div
</div>
</div>
<script>
$(document).ready(function(){
$("#divOne").hover(function(){
$(this).css("visibility", "visible");
}, function(){
$(this).css("visibility", "hidden");
});
$("#delelte").on("click",()=>{
$("#divOne").children().remove();
});
});
</script>

You can try this one with jQuery:
$('body').on('mouseenter', '.childElement', function(e){
$(this).append('<div class="remove">remove it</div>');
$('.childElement').on('mouseleave', function(){
$('.remove').remove();
});
$('body').on('click', '.remove', function(e){
$(this).parent().remove();
});
});
.childElement {
width:100px;
height:100px;
background-color:#f3f3f3;
margin-top:10px;
padding:10px;
}
.remove {
position:absolute;
width: 100px;
height: 30px;
background: #000;
color:#fff;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div id="videos">
<div class="childElement">
first div
</div>
<div class="childElement">
second div
</div>
<div class="childElement">
third div
</div>
</div>

Check if div-container has more than one div-inner no jQuery

I need a if else function that checks if div_container has more than one div_inner inside of it with Javascript only.
Here's my example code:
var inner = document.querySelector('.inner')
var container = document.querySelector('.container').innerHTML;
if(container > '1') {
container.classList.add('test');
}
else {
// do nothing
}
.test {
color: red;
}
<div class="container">
<div class="inner">Test</div>
</div>
<div class="container">
<div class="inner">Test</div>
<div class="inner">Test</div>
</div>
I only want to use Javascript. No jQuery at all.

You have to use querySelectorAll() to get all the container and loop through them to check the inner div's length:
var container = document.querySelectorAll('.container');
container.forEach(function(el){
var inner = el.querySelectorAll('.inner').length;
if(inner > 1) {
el.classList.add('test');
}
else {
// do nothing
}
});
.test {
color: red;
background-color: lightgray;
}
<div class="container">
<div class="inner">Test</div>
</div>
<div class="container">
<div class="inner">Test</div>
<div class="inner">Test</div>
</div>

You can use querySelectorAll()
for (const container of document.querySelectorAll('.container')) {
if (container.querySelectorAll('.inner').length > 1) {
container.classList.add('test');
}
}
.test {
color: red;
}
<div class="container">
<div class="inner">Test</div>
</div>
<div class="container">
<div class="inner">Test</div>
<div class="inner">Test</div>
</div>

Why my array gets overlaped

I have a simple project where i am trying to learn the concepts of vue.js using componenetes, comunication between components(i use eventBus) i am using the webkit-simple template to approach this, basicly what happens, is that i have 1 component that consists in a simple textarea where i add some text, that text should be displayed in my second component, that is a template where i render a array with all my texts that i inserted, like a list of quotes.
component addQuote
<template>
<div class="row">
<div class="col-md-12">
<div class="form-group">
<div class="col-md-offset-3 col-md-6">
<label>Quote:</label>
<textarea v-model="quote.text" class="form-control" rows="5"></textarea>
<div class="text-center">
<button #click="addQuote" class="btn btn-primary center">Add Quote</button>
</div>
</div>
</div>
</div>
</div>
</template>
<script>
import { quoteBus } from '../main.js';
export default {
methods: {
addQuote() {
if (this.counter < 10) {
this.counter++;
this.quote.key =+ new Date();
quoteBus.$emit('saveQuote', this.quote);
}
}
},
data: function () {
return {
quote: {},
counter: 0
}
},
created(){
quoteBus.$on('decreaseCounter', () => {
this.counter--
});
}
}
</script>
<style scoped>
.row {
margin-top: 40px;
}
.center {
margin: 0 auto;
}
div .text-center {
margin-top: 20px;
}
</style>
component quotes
<template>
<div class="row">
<div class="col-md-3" v-for="(quote,$index) in quotes" #click="deleteQuote($index)" :key="quote.key">
<div class="spacing">
<h2>{{quote.text}}</h2>
</div>
</div>
</div>
</template>
<script>
import { quoteBus } from '../main.js';
export default {
data: function () {
return {
quotes: []
}
},
methods: {
deleteQuote(i){
this.quotes.splice(i,1);
quoteBus.$emit('decreaseCounter');
}
},
created() {
quoteBus.$on('saveQuote', quote => {
this.quotes.unshift(quote);
console.log(JSON.stringify(this.quotes));
});
}
}
</script>
<style scoped>
h2 {
font-family: 'Niconne', cursive;
}
div .col-md-3 {
border: 1px solid darkgray;
padding: 10px;
}
div .row {
margin-top: 40px;
}
.spacing {
margin: 10px;
padding: 10px;
}
</style>
the problem is, everytime i add a quote the text replace all the elements before.
Example:
9th entry: text: "abcdef", all the entries in the array has this value in text, all my divs has the value of abcdef, what is happening :S

const quoteBus = new Vue();
Vue.component('addQuote', {
template: '#addQuote-template',
methods: {
addQuote() {
if (this.counter < 10) {
this.counter++;
this.quote.key = +new Date();
quoteBus.$emit('saveQuote', Object.assign({}, this.quote));
}
}
},
data: function() {
return {
quote: {},
counter: 0
}
},
created() {
quoteBus.$on('decreaseCounter', () => {
this.counter--
});
}
});
Vue.component('quotes', {
template: '#quotes-template',
data: function() {
return {
quotes: []
}
},
methods: {
deleteQuote(i) {
this.quotes.splice(i, 1);
quoteBus.$emit('decreaseCounter');
}
},
created() {
quoteBus.$on('saveQuote', quote => {
this.quotes.unshift(quote);
console.log(JSON.stringify(this.quotes));
});
}
});
new Vue({
el: '#app'
});
<script src="//cdnjs.cloudflare.com/ajax/libs/vue/2.2.4/vue.min.js"></script>
<template id="addQuote-template">
<div class="row">
<div class="col-md-12">
<div class="form-group">
<div class="col-md-offset-3 col-md-6">
<label>Quote:</label>
<textarea v-model="quote.text" class="form-control" rows="5"></textarea>
<div class="text-center">
<button #click="addQuote" class="btn btn-primary center">Add Quote</button>
</div>
</div>
</div>
</div>
</div>
</template>
<template id="quotes-template">
<div class="row">
<div class="col-md-3" v-for="(quote,$index) in quotes" #click="deleteQuote($index)" :key="quote.key">
<div class="spacing">
<h2>{{quote.text}}</h2>
</div>
</div>
</div>
</template>
<div id="app">
<add-quote></add-quote>
<quotes></quotes>
</div>
The problem is that there is only one instance of this.quote in your addQuote component. You pass that particular object to quotes to be put into the array every time. When an object is put into an array, it is by-reference. If you put the same object into an array multiple times, you just have multiple references to the object's contents. Every element of your array is a reference to the same set of contents.
You need to send a copy of the object instead:
quoteBus.$emit('saveQuote', Object.assign({}, this.quote));

Refactoring jQuery repeating pattern

I have painted my self into a corner in order to quickly prototype.
What's the best way to refactor the following jQuery code? Its functionality is to toggle between some sidebar navigation items. I need it to be more dynamic in order to be scalable.
Would you add the IDs inside the if statements, in an array and iterate through them? Use variables? Create a function and call it on the html side onClick? No matter what I think of, it stills leads to a bunch of repeating code.
Thank you!

You should group using the common CSS class, i.e. header and content. Using the established relationship you can target the others content holder and content associated with the current clicked header element.
$('.container .header').on('click', function() {
//Get the current element
var $this = $(this);
//find the content
var $content = $this.closest('.container').find('.content'); //$this.next()
//get all contents
var content = $('.container .content');
//Slide up others
content.not($content).slideUp(350);
//Slide down
$content.slideToggle(350);
});
.content {
display: none
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="container">
<div class="header" id="settingsClick">Click Me</div>
<div class="content" id="settingsContainer">Content...</div>
</div>
<div class="container">
<div class="header" id="addClick">Click Me</div>
<div class="content" id="addContainer">Content...</div>
</div>
<div class="container">
<div class="header" id="noteClick">Click Me</div>
<div class="content" id="noteContainer">Content...</div>
</div>

the best bet would be to do it like so
$(document).on('click', ".trigger", function() {
var sibling_content = $(this).siblings(".content");
if (!sibling_content.hasClass('active')) {
$(".content").slideUp('slow').removeClass('active');
sibling_content.slideDown('slow').addClass('active');
} else {
sibling_content.slideUp('slow').removeClass('active');
}
})
.trigger {
background-color: red;
color: white;
font-size: 16px;
}
.content {
background-color: blue;
color: white;
font-size: 16px;
padding: 20px 0;
display: none;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
