How do I detect a click outside an element?
(91 answers)
Closed 1 year ago.
I'm trying to achieve that a div hides if user clicks anywhere except on the element. I've got following code doing toggle() if user clicks on a button. I want the button click to stay plus if the Details element is visible, reacts to other parts of the screen.
$('.nav-toggle').click(function() {
//get collapse content selector
var collapse_content_selector = $(this).attr('href');
//make the collapse content to be shown or hide
var toggle_switch = $(this);
$(collapse_content_selector).toggle(function() {
if ($(this).css('display') == 'none') {
//change the button label to be 'Show'
toggle_switch.html('Show Details');
} else {
//change the button label to be 'Hide'
toggle_switch.html('Hide Details');
}
});
});
You can resort to the concept of event delegation.
$(function() {
$(document).on('click', function(e) {
if (e.target.id === 'div1') {
alert('Div Clicked !!');
} else {
$('#div1').hide();
}
})
});

I did not understand what you meant by integrating with the other part.. This is the basic idea..
You can use the jQuery .blur() function to hide a div when user click on other element (like link, boutton, whathever..)
The blur event is fire when an element is loosing the focus (user select another element on the DOM tree)
I don't understand the link with your toggle. If your toggle button manage the DIV, its inside the toggle function that you should place the hide()/show() on the div, in the same time as updating the text of the button.

I have this code for toggling menus on my site. It will open a menu on click, close others open when you click another and close them all if you click outside.
The issue is, I'm now using this for my search bar to appear too, but if you click inside the search box it vanishes - woops. Would it be possible to amend the hiding code to detect if the user wasn't clicking inside a specific area of the code?
// navbar toggle menu
$(document).on('click', ".toggle-nav > a", function(event) {
event.preventDefault();
event.stopPropagation();
var $toggle = $(this).closest('.toggle-nav').children('.toggle-content');
if ($toggle.hasClass('toggle-active'))
{
$($toggle).removeClass('toggle-active');
}
else
{
$(".toggle-content").removeClass('toggle-active');
$($toggle).addClass('toggle-active');
}
});
// hide the toggle-nav if you click outside of it
$(document).on("click", function ()
{
$(".toggle-content").removeClass('toggle-active');
});
Instead of using click, this uses mouseup. If the target is, for example #search-bar, it won't remove toggle-active from toggle-content elements.
$(document).mouseup(function(e) {
if (!$(e.target).is('#search-bar')) {
$(".toggle-content").removeClass('toggle-active');
}
});
You can see it in action with this jsFiddle.
Hopefully this helps.
I have a popup window that has a form in it and to stop the popped up div clicks from closing the window I've used:
$(".popup").click(function () {
$(".popup").css("display", "none");
}).children().click(function(e) {
return false;
});
However this works perfectly except with checkboxes whereby it disables checking them.
Is there any way around this?
popup is an overlay, then popupInner holds the form.
Try replacing your code with this:
$(".popup").click(function(e) {
if (e.target == this) $(this).hide();
});
It would hide the popup only if clicked on the element with class popup and not its children, it would also keep the functionality of the children intact.
I have an autocomplete dropdown that appears when a user starts typing in a textbox (I'm using jquery mobile but I don't think that's important to my problem). I want to be able to hide the whole dropdown list when a user clicks anywhere on the page. However, I don't want to hide the dropdown when a user actually clicks on the dropdown itself.
Is there a way I could catch the click event in order to know what was clicked?
Here's my blur function:
//hide autocomplete when dropdown is not clicked
$("#search-div input").blur(function () {
$("#autocomplete-list").hide();
});
I was thinking of somehow putting an if statement in my blur function. Here's my pseudo code:
if( dropdown clicked)
{
run code to take text from dropdown and place in textbox
}
else
{
hide dropdown
}
Would it be possible to know whether my dropdown is clicked or something else is clicked while in my blur function? When I debug my javascript I'm only seeing an event that's related to the textbox doing the blur()
Edit:
Here is a function I'm using to handle when the dropdown is clicked:
$( document).on( "click", "#autocomplete-list li", function() {
var selectedItem = event.target.innerHTML;
$(this).parent().parent().find('input').val(selectedItem);
$('#autocomplete-list').hide();
runSearchQuery();
});
You can listen for any click, not just a blur, and then check what the clicked element was. e.currentTarget gives you what was clicked.
var clickHandler = function(e) {
if ($(e.currentTarget).hasClass('dropdown')) {
// do nothing
} else {
// Make sure you unregister your event every
// time the dropdown is hidden.
$(window).off('click', clickHandler);
// hide
}
}
// When the dropdown comes down, register an event on the whole page.
$(window).on('click', clickHandler);
I have a login button (class = login-button), where if the button click, it will show a div box with login form in it (class = login-box) e.g:
$(document).ready(function(){
$('.login-button').click(function(){
$( ".login-box" ).show();
});
});
and now, the way I hide the .login-box if user click outside is like this
$(document).mouseup(function(e){
var targetbox = $('.login-box');
if(!targetbox.is(e.target) && targetbox.has(e.target).length === 0){
$('.login-box').fadeOut('fast');
}
});
But the problem is on Chrome and Safari only (not Firefox), if user select a textbox as in would like to delete the text, highlight the text, but release the button outside the div, it will hide the login-box, but on Firefox it's not.
My question is how to prevent this from happening. Is there anyway to hide the box if and only if user click the mouse outside the box and release the mouse outside the box ?
Just use click instead of mouseup - what you described is what click does. Prevent the event bubbling up to stop the click of the button clicking document.
Demo
$(document).ready(function(){
$('.login-button').click(function(event){
event.stopPropagation();
$( ".login-box" ).show();
});
});
$(document).click(function(e){
var targetbox = $('.login-box');
if(!targetbox.is(e.target) && targetbox.has(e.target).length === 0){
$('.login-box').fadeOut('fast');
}
});
I have a notification dropdown similar to what stackoverflow has. So when the user request the notifications window I open and close my dropdown div using .show and .hide.
Meanwhile I also want to close it when the user clicks anywhere outside my dropdown div.
My approach was to do the following on my layout.cshtml :
$(document).on("click", onDocumentClick);
function onDocumentClick(event) {
var target = $(event.target);
if (!target.hasClass('nbr-notifications')) {
if ($('#notifications-dropdown').css('display') === 'block') {
$('#notifications-dropdown').hide();
}
}
}
My question and concern is : Is this the best way to do it? From the performance perspective? Since I am handling all clicks on my document everytime.
Couldn't you use this if you are not sure where the element would be?
$('body').on("click",".nbr-notifications", onClick)
.on('blur','.nbr-notifications',closeNotifications);
function onClick(event) {
if ($('#notifications-dropdown').css('display') === 'block') {
$('#notifications-dropdown').hide();
}
}
function closeNotifications()
{
//close it
}
Here only responding to clicks on elements with the class 'nbr-notifications' rather than hooking event handler for all clicks and check if the target is the required one.
If you want the notification to disappear after it loses focus why not just bind a focusout event specifically to that element instead of click to the entire document.
http://api.jquery.com/focusout/
$('.nbr-notifications').on('focusout',function(){
//close functionality here. something like: $(this).hide();
});
