OpenLayers 3 - Div on top of map is not capturing click - javascript

I have a form/div displayed on top of the map. I want to make it so that it is hidden when there is a click outside the form/div area but not when the click is inside the form/div.
I can't get to detect when the click is done inside the div. Instead all clicks inside the form/div are detected as done on the map, as if the div doesn't exist.
<div id="map" class="map"><div id="popup">
//input data of form
</div> </div>
<script>
map.on('click', function(evt) {
console.log('Clicked #map');
//one method I tried from another stack overflow answer
(evt.target !== this) ? $("#popup").show() : $popup.hide();
var feature = map.forEachFeatureAtPixel(evt.pixel,
function(feature) {
return feature;
});
if (feature) {
loadInfo(feature.get('id'));
$("#popup").show();
}
});
$("popup").on('click', function(e) {
e.stopPropagation();
console.log('Clicked #popup');
});
</script>
Output
Clicked #map
Clicked #popup
As you can see in the code I tried few different methods on detecting clicks on the popup but none of them worked. All of them are as if, the popup is not even there.
I am using openlayers3 if that matters.

You can use Event.stopPropagation() to prevent further propagation of the current click event in the capturing and bubbling phases:
var $map = $('#map'),
$popup = $('#popup');
$map.on('click', function(e) {
console.log('Clicked #map');
(e.target !== this) ? $popup.show() : $popup.hide();
});
$popup.on('click', function(e) {
e.stopPropagation();
console.log('Clicked #popup');
});
#map {
background-color: grey;
width: 80%;
height: 120px;
margin: auto;
padding: 40px;
}
#popup {
background-color: #000000;
color: #ffffff;
width: 60%;
margin: auto;
padding: 20px;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="map" class="map">
<div id="popup">
// input data of form
</div>
</div>

fadeToggle on body click

I have this div which shows/hides with display:none/block by clicking on an id #cart. The div opens and closes by clicking on element with the id but I want to close the div on body click too. How can I do it please?
Code I am using is below:
jQuery("#cart").on("click", function() {
jQuery(".shopping-cart").fadeToggle( "fast");
});
jQuery("#cart, body").on("click", function() {
jQuery(".shopping-cart").fadeToggle("fast");
});
What you can do is add a listener to the entire window and check for clicks. When there is a click, we check which element has been clicked and check on whether it's the element. We repeat this for the parent element as well.
<!DOCTYPE html>
<html>
<head>
<script>
function checkClickOutsiteElement(clickedElement, elementToCheck){
var iterator = clickedElement;
while(true){
// The click was in the element.
if( iterator === elementToCheck )
return;
// Go to the parent.
if( !iterator.parentElement ){
alert('outside menu');
return;
}
iterator = iterator.parentElement;
}
}
window.addEventListener('click', function(event){
checkClickOutsiteElement(event.target, document.getElementById('menu'));
});
</script>
</head>
<body>
<div class="wrapper">
<div id="menu" style="width: 100px; height: 100px; background-color: red;"></div>
</div>
<div class="wrapper">
<div id="not_menu" style="width: 100px; height: 100px; background-color: green;"></div>
</div>
</body>
</html>
You probably want two separate functions, since your cart button should toggle both ways, but the body click handler should only toggle out.
Protip: on() isn't doing anything for you that click() wouldn't, the way you're using it. The latter is a bit cleaner.
jQuery("#cart").click(function() {
jQuery(".shopping-cart").fadeToggle("fast");
});
jQuery("body").click(function() {
jQuery(".shopping-cart").fadeOut("fast");
});
Protip 2: Easily and safely alias jQuery to $ like so:
jQuery(function($) { // document ready with dollar alias
$("#cart").click(function() {
...
});
I have this div which shows/hides with display:none/block by clicking
on an id #cart. The div opens and closes by clicking on element with
the id but I want to close the div on body click too.
In vanilla javascript, you can:
write a function to show / hide the div
add a click event listener to #cart
add a click event listener to body
Working Example:
// Grab #cart
const cart = document.getElementById('cart');
// Grab .myDiv
const myDiv = document.getElementsByClassName('div')[0];
// Function to toggle .myDiv
const toggleMyDiv = (e) => {
if (e.target === e.currentTarget) {
myDiv.dataset.display = (myDiv.dataset.display === 'show') ? 'hide' : 'show';
}
}
// Add Click Event Listener to #cart
cart.addEventListener('click', toggleMyDiv, false);
document.body.addEventListener('click', toggleMyDiv, false);
body,
#cart {
cursor: pointer;
}
div {
display: inline-block;
width: 100px;
height: 100px;
line-height: 100px;
text-align: center;
font-weight: bold;
}
#cart {
color: rgb(255, 255, 255);
background-color: rgb(255, 0, 0);
}
.div {
color: rgb(255, 0, 0);
background-color: rgb(255, 255, 0);
}
.div[data-display="show"] {
opacity: 1;
}
.div[data-display="hide"] {
opacity: 0;
}
<div id="cart">Cart</div>
<div class="div show" data-display="show">myDiv</div>

Jquery: How to hide an element while it is in orther element?

how to hide a "cube-2" by click on "click-me" that its included by "cube-2"?
I made an event but it deleted all of my cube-2, I want to hide cube-2 one by one. Anyone can solve this? please help me.
$('.cube-1').click(function name(params) {
$('.cube-1').append('<div class="cube-2"><div class="click-me">click me to hide this cube</div></div>');
// how to add event click on "click-me" to hide "cube-2"??
})
.cube-1 {
width: 100px;
height: 100px;
float: left;
background: blue;
}
.cube-2 {
margin-left: 100px;
width: 100px;
height: 100px;
float: left;
background: red;
}
.click-me {
width: 100%;
height: 50px;
background: white;
}
<html>
<head>
<script src="https://code.jquery.com/jquery-3.3.1.slim.min.js"></script>
</head>
<div class="cube-1"></div>
</html>
You can add an id to your cube-2 div and it's corresponding click-me anchor tag and remove only the div with that Id.
You may also want to check Template string
$('.cube-1').click(function name(e) {
var cubeCounter = 1;
if (e.target.className == "cube-1") {
$('.cube-1').append(`<div class=cube-2 id=cube-${cubeCounter}><div class=click-me id=${cubeCounter}>click me to hide this cube</div></div>`);
cubeCounter++;
}
})
$(document).on('click', '.click-me', function name(e) {
var cubeId = e.target.id;
$(`#cube-${cubeId}`).remove();
})
you need to handle dyanamic click event of second cube and prevent click event of parent control, when child cube is clicked
$('.cube-1').click(function name(e) {
if(e.target.className == "cube-1")
{
$('.cube-1').append('<div class="cube-2"><div class="click-me">click me to
hide this cube</div></div>');
}
});
$(document).on('click','.cube-2',function name(e)
{
$(this).remove();
// how to add event click on "click-me" to hide "cube-2"??
})
Please check working demo [Link]
https://jsfiddle.net/2L3k5hcb/
You just need to bind your click on div while you appending your cube-2.
Add your script as below-
$('.cube-1').on('click',function(event){
$('.cube-1').append('click me to hide this cube');
})
function myFunction(param) {
event.stopPropagation();
$(param).remove();
}
you can use below method for dynamicly generated elements.
$(document).on('click', '.click-me', function (e) {
$(this).hide();
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
Try this
$(document.body).on('click', '.cube-2', function (event) {
$(this).hide();
});
$('.cube-1').click(function(event) {
if(event.target.className =='cube-1')
$('.cube-1').append('<div class="cube-2"><div class="click-me">click me to hide this cube</div></div>');
// how to add event click on "click-me" to hide "cube-2"??
})
.cube-1 {
width: 100px;
height: 100px;
float: left;
background: blue;
}
.cube-2 {
margin-left: 100px;
width: 100px;
height: 100px;
float: left;
background: red;
}
.click-me {
width: 100%;
height: 50px;
background: white;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="cube-1"></div>

clicking for show div but hide again + make body position stay

i make profile form, i clicked this, form is show but hidden instally
I want to click the link if the form appears without disappearing again, and if clicked outside in the form, from hidden and the web position stay without scrolling to up
i code used
$('.profile-link').click(function(e) {
$(".profile-frm").addClass("show-prfrm");
});
$(document).mouseup(function(e) {
var container = $(".profile-frm");
var clickfuncion = $('.profile-link').click;
if (container.is(':visible')) {
// if the target of the click isn't the container nor a descendant of the container
if (!container.is(e.target) && container.has(e.target).length === 0) {
e.preventDefault();
$('body').width($('body').width());
container.removeClass("show-prfrm");
}
}
});
I think the only tricky part is to put a click handler on the document and do different things when the target element is the button, the menu, or anything else.
const button = document.querySelector('button');
const menu = document.querySelector('#menu');
document.addEventListener('click', event => {
menu.classList.add('hide');
if (event.target == button || event.target == menu)
menu.classList.remove('hide');
});
#menu {
position: absolute;
top: 50;
border: 1px solid #555;
background-color: #555;
border-radius: 10px;
height: 175px;
width: 100px;
}
.hide {
display: none;
}
<link href="https://cdnjs.cloudflare.com/ajax/libs/skeleton/2.0.4/skeleton.min.css" rel="stylesheet" />
<button>Menu</button>
<div id="menu" class="hide"></div>

Why does the following Jquery event.target does not work properly

Following is my code in question
(function($) {
'use strict';
var button = $('#open_button');
var box = $('#dropdown');
function init() {
eventsInit();
}
function eventsInit() {
box.hide();
button.on('click', open);
}
function open(event) {
if (event.target !== button[0]) {
box.hide();
} else {
box.show();
}
}
init();
})(jQuery);
body,
html {
padding: 0;
margin: 0;
}
#container {
height: 100px;
width: 800px;
margin: 0 auto;
}
h1 {
color: white;
}
#dropdown {
height: 600px;
width: 800px;
background-color: black;
margin: 0 auto;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="container">
<form action="" id="open_button">
<input type="text" placeholder="Enter the text" />
</form>
</div>
<div id="dropdown"></div>
I need to dropdown when I click on the input form input element and close it when I click outside.
My code I believe it says, if the click target is not the button, close the dropdown, else show.
Could someone explain, why doesnt it work ?
(event.target !== button[0]) is always true.
event.target is the <input> field.
button[0] is the <form> element.
You could move the #open_button id to the input field, that would cause the box to appear when the user clicks the input field -- but then the box would never disappear (because your if condition would never return true.)
What you really want are focus and blur handlers on the input field, to show and hide the box respectively:
$('#open_button input').on('focus', function() {
$('#dropdown').show()
}).on('blur', function() {
$('#dropdown').hide()
});
// added to answer per comment below:
$('#dropdown').on('mousedown',function(e) {
e.preventDefault() // prevent input field from losing focus when user clicks inside the box
});
$('#dropdown').hide();
#dropdown {
height: 600px;
width: 800px;
background-color: black;
margin: 0 auto;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="container">
<form action="" id="open_button">
<input type="text" placeholder="Enter the text" />
</form>
</div>
<div id="dropdown"></div>

Trouble Removing One Child DIV At A Time

I am building a simple Grocery List App and I am having issues trying to remove a place holder div element.
HTML
<!DOCTYPE html>
<html>
<head>
<title>Grocery List App</title>
<link type="text/css" href="style/form.css" rel="stylesheet"/>
</head>
<body>
<div id="container">
<div id="left_side">
<div id="to_buy">To Buy:</div>
</div>
<div id="right_side">
<div id="in_cart">In Cart:</div>
</div>
</div>
<input type="text" id="item_body" placeholder="Type Item to Add">
<script src="scripts/jquery-1.11.2.min.js"></script>
<script src="scripts/grocery.js"></script>
<script src="scripts/jquery-ui/jquery-ui.js"></script>
</body>
</html>
JS
$(function () {
var rmv = false;
$('#item_body').keydown(function(e) {
if (e.keyCode == 13) {
var add = $('#item_body').val();
$("#to_buy").append('<div class="draggable_item">' + add + '</div>');
$("#in_cart").append('<div class="holder"></div>');
}
$(".draggable_item").draggable( {
axis: "x"
});
$(".draggable_item").dblclick(function() {
this.remove();
$('#in_cart > div:first').remove();
});
});
});
CSS
#to_buy {
float:left;
width: 50%;
height: 100%;
color: #00E5EE;
}
#in_cart {
float: left;
width: 49%;
height: 100%;
color: #00E5EE;
}
#container {
width:100%;
height: 100%;
}
#left_side {
height: 100%;
width: 50%;
float:left;
background: #5D5851;
}
#right_side {
height: 100%;
width: 50%;
float: left;
background: #6D5D4D;
}
#item_body {
float:left;
clear:both;
color: #326B62;
}
body {
background: #B1ADA5;
}
.draggable_item {
color: #FFF;
}
.holder {
height: 20px;
}
So the screen is split vertically between "to_buy" and "in_cart." When I add an item to "to_buy" I also add a "dummy" div to "in_cart" so that the two sides remain even. However, when I double click to remove an item, when
$('#in_cart > div:first').remove();
gets called, first one div is removed, then on the next double click two, then four etc etc. Apparently, it is getting called multiple times or something else wonky is going wrong.
This is because you bind event handlers for double click event on every Enter key press so they multiply on every item addition. Just move dblclick registration outside:
var rmv = false;
$('#item_body').keydown(function (e) {
if (e.keyCode == 13) {
var add = $('#item_body').val();
$("#to_buy").append('<div class="draggable_item">' + add + '</div>');
$("#in_cart").append('<div class="holder"></div>');
}
$(".draggable_item").draggable({
axis: "x"
});
});
$("#left_side").on("dblclick", ".draggable_item", function () {
this.remove();
$('#in_cart > div:first').remove();
});
Also note, that it makes sense to delegate double click event to the parent container #left_side so you don't have to worry about presence of elements at the time of event registration.
