How to determine if a bootstrap collapse is opening or closing? - javascript

If I have a bootstrap collapse how can I determine from a click event wether the collapse is opening or closing?
Here is my click event or maybe there is a better way then to use a click event?
$(document).on("click", "a.register-student-link", function() {
// do some stuff to check if opening or closing
}
<div>
<a id=#space.EventId class="register-student-link" data-toggle="collapse" href=#spaceIdWith aria-expanded="false" aria-controls="collapseExample">
Register Student
</a>
</div>

Bootstrap uses the aria-expanded attribute to show true or false if the region is collapsed or not.
var isExpanded = $(collapsableRegion).attr("aria-expanded");

Try:
$('#collapseDiv').on('shown.bs.collapse', function () {
console.log("Opened")
});
$('#collapseDiv').on('hidden.bs.collapse', function () {
console.log("Closed")
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.5/js/bootstrap.min.js"></script>
<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.5/css/bootstrap.min.css" rel="stylesheet"/>
<div>
<a id=#space.EventId class="register-student-link" data-toggle="collapse" href="#collapseDiv" aria-expanded="false" aria-controls="collapseExample">Register Student</a>
</div>
<div class="collapse" id="collapseDiv">This is the collapsible content!</div>
(based on https://stackoverflow.com/a/18147817/2033574 (Kevin mentioned) and http://www.bootply.com/73101)

I needed a way to determine if the element was collapsed BEFORE actually collapsing. Whereas the event listeners only trigger afterwards.
//Will return true if uncollapsed
$('#collapseDiv').hasClass('in');
//Will return true if in the process of collapsing
$('#collapseDiv').hasClass('collapsing');
//Will return true if collapsed
$('#collapseDiv').hasClass('collapse');

You can watch the event hidden.bs.collapse
see fiddle: http://jsfiddle.net/kyeuvx1d/

if(!$("#id").hasClass('show')){
alert("Uncollapsed");
}
else {
alert("Collapsed");
}
for Bootstrap 4

Expand/Collapse several blocks at the same time?

I have several blocks in my page. I use bootstrap 4 alpha 6 version. I want expand/collapse these blocks by clicking one button. Right know I use next js code and it only open all blocks but how to close them?! How to fix this problem?
HTML:
<div class="card">
<div class="card-header">
<button id='expand-collapse' type="button" data-parent="#blocks" data-toggle="collapse" data-target=".block" aria-expanded="false" aria-controls=".block">
</button>
</div>
<div class="card-block">
<div id="blocks">
<div class="list-group">
<div class="list-group-item">
<a data-toggle="collapse" href="#block-1" aria-expanded="false" aria-controls="block-1"OPEN FIRST</a>
<div class="collapse block" id="block-1">
<!--FIRST BLOCK BLOCK-->
</div>
</div>
<div class="list-group-item">
<a data-toggle="collapse" href="#block-2" aria-expanded="false" aria-controls="block-2">OPEN SECOND</a>
<div class="collapse block" id="block-2">
<!--SECOND BLOCK-->
</div>
</div>
<div class="list-group-item">
<a data-toggle="collapse" href="#block-3" aria-expanded="false" aria-controls="block-3">OPEN THIRD</a>
<div class="collapse block" id="block-3">
<!--THIRD BLOCK-->
</div>
</div>
</div>
</div>
</div>
</div>
JAVASCRIPT:
$(function() {
$('#expand-collapse').on('click', function() { // We capture the click event
var target = $(this).attr('data-target'); // We get teh target element selector
$(target).each(function() { // Loop through each element
if ($(this).hasClass('show')) { // Check if it's already visible or not
$(this).collapse('hide'); // Show and hide accordingly
} else {
$(this).collapse('show');
}
});
});
});
$(document).ready(function () {
$('.collapse')
.on('shown.bs.collapse', function(event) {
event.stopPropagation();
$(this)
.parent().parent()
.find(".fa-commenting-o")
.removeClass("fa-commenting-o")
.addClass("fa-commenting");
}).on('hidden.bs.collapse', function(event) {
event.stopPropagation();
$(this)
.parent().parent()
.find(".fa-commenting")
.removeClass("fa-commenting")
.addClass("fa-commenting-o");
});
});
The code that youve used will work as expected in bootstrap3 due to the way collapse was handled then (You can verify it by using JS & CSS of bootstrap V3)
Comming to solving your problem the following snippet would work as expected:
$(function() {
$('#expand-collapse').on('click', function() { // We capture the click event
var target = $(this).attr('data-target'); // We get teh target element selector
$(target).each(function() { // Loop through each element
if ($(this).hasClass('show')) { // Check if it's already visible or not
$(this).collapse('hide'); // Show and hide accordingly
} else {
$(this).collapse('show');
}
});
});
});
TIP:
We can also pass toggle argument to the collapse function and get rid of the if-else condition
$(this).collapse('toggle'); can be used to replace the if-else
But I did not use this in my example to show that you can add additional computation in it
Working Fiddle
UPDATE:
The updated question asks for individual control for the block
To acheive that, we can use the default method of triggering the action with a button element.
<div class="list-group-item">
<div class="collapse block" id="block-1">
FIRST BLOCK
</div>
</div>
<button class="btn btn-primary" type="button" data-toggle="collapse" data-target="#block-1">
Block 1
</button>
You can find the updated jsFidde here
Add an else statement to handle all other cases that don't match the criteria to show. Try this:
$(function () {
$('#expand-collapse').on('click',function(){
$('[data-toggle="collapse"]').each(function(){
var objectID=$(this).attr('data-target');
if($(objectID).hasClass('.collapse')===false)
{
$(objectID).collapse('show');
} else {
$(objectID).collapse('hide');
}
});
});
});
There is an error with the Bootstrap v4.0.0-alpha.6 version with the transitioning that will be solved on the next release.

How to prevent double click of "click" jquery

I've this simple Fiddle where if a user clicks plus glyphicon, I show the collapsed content and change the glyphicon to 'minus' and vice-versa on click of minus glyphicon.
But, when I double click the plus glyphicon, the content shows and the glyphicon is not changed to minus. For the next single clicks, the content is shown when 'minus' glyphicon appears. How can I prevent the double click ?
HTML
<div class="divcontainer">
<span>Click -----></span>
<span class="glyphicon glyphicon-plus" data-toggle="collapse" href="#collapsecontent"></span>
</div>
<div class="collapse" id="collapsecontent">
content
</div>
jQuery
$(document).ready(function () {
$('.glyphicon-plus').click(function () {
$(this).parent("div").find(".glyphicon-plus")
.toggleClass("glyphicon-minus");
});
});
Instead of 'onclick' function use collapse hide and show events. Please refer below code:
$(document).ready(function() {
$('#collapsecontent').on('show.bs.collapse', function(args) {
onContainerClick($(this).parent());
});
$('#collapsecontent').on('hide.bs.collapse', function(args) {
onContainerClick($(this).parent());
});
});
function onContainerClick(args) {
$(args).find(".glyphicon-plus")
.toggleClass("glyphicon-minus");
}
add dblclick event handler too
$(document).ready(function () {
$('.glyphicon-plus').click(function () {
$(this).parent("div").find(".glyphicon-plus")
.toggleClass("glyphicon-minus");
});
$('.glyphicon-plus').dblclick(function () {
$(this).parent("div").find(".glyphicon-plus")
.toggleClass("glyphicon-minus");
});
});
.divcontainer{
background:aqua;
width:100%
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

<div class="divcontainer">
<span>Click -----></span>
<span class="glyphicon glyphicon-plus" data-toggle="collapse" href="#collapsecontent"></span>
</div>
<div class="collapse" id="collapsecontent">
content
</div>
just use your own jquery handler. Remove data-toggle attr and use this
$(document).ready(function () {
$('.glyphicon-plus').click(function () {
$('.collapse').slideToggle();
$(this).parent("div").find(".glyphicon").toggleClass("glyphicon-plus").toggleClass("glyphicon-minus");
});
});
I think it should work now.
try this
$(this).prop('disabled', true);

Toggle the glyphicon with bootstrap collapse

I have glyphicon-chevron-down when div is in collapsed state,i want to replace it with glyphicon-chevron-up when the div is in collapse in state.I have many of these collapsible divs in my project.So i need to toggle the glyphicon on press of particular collapsibe content(or div).
HTML
<div class="divcontainer">
<span>Click -----></span>
<span class="glyphicon glyphicon-chevron-down" data-toggle="collapse" href="#collapsecontent"></span>
</div>
<div class="collapse" id="collapsecontent">
content
</div>
JavaScript
$(document).ready(function () {
$('.glyphicon-chevron-down').click(function () {
$(this).parent("div").find(".glyphicon-chevron-down")
.toggleClass("glyphicon-chevron-up");
});
});
Fiddle here
Your JS is putting an emphasis on the wrong thing. Find is very slow and best avoided if possible -- and it's very possible here. Just change it to this:
$(document).ready(function () {
$('.glyphicon').click(function () {
$(this).toggleClass("glyphicon-chevron-down").toggleClass("glyphicon-chevron-up");
});
});
JS Fiddle: http://jsfiddle.net/ft4mnynh/
Try the FIDDLE,
I have changed the selectors and events like below
$(document).ready(function () {
$('.divcontainer').click(function () {
$(this).find("span:eq(1)")
.toggleClass('glyphicon-chevron-down')
.toggleClass("glyphicon-chevron-up");
});
});
Hope this helps
Use this below jquery code and just change glyphicon name as you wish
<script>
$('.collapse').on('shown.bs.collapse', function(){
$(this).parent().find(".glyphicon-menu-right").removeClass("glyphicon-menu-right").addClass("glyphicon-menu-down");
}).on('hidden.bs.collapse', function(){
$(this).parent().find(".glyphicon-menu-down").removeClass("glyphicon-menu-down").addClass("glyphicon-menu-right");
});
</script>
You need to toggle both classes chevron-up and chevron-down.
You can find the correct div using the more general glyphicon class.
I also added id to the div, so you don't need to find it by the down class
See: http://jsfiddle.net/amwLaojj/1/
$(document).ready(function () {
$('#myglyph').click(function () {
$(this).parent("div").find(".glyphicon")
.toggleClass("glyphicon-chevron-up")
.toggleClass("glyphicon-chevron-down");
});
});
Update:
Instead of ID, you can use:
$('.glyphicon[data-toggle=collapse]').click(function () {
Updated in: http://jsfiddle.net/amwLaojj/3/
The following code worked for me. As far as I can tell the bootstrap js events only fire on the "div.collapse" element, i.e., the hidden and shown block(s). Even the jquery "click" event on "div.panel-heading" or any child was unresponsive.
<div class="panel-heading" role="tab" id="headingOne">
<h4 class="panel-title">
<a role="button" data-toggle="collapse" data-parent="#accordion" href="#collapseOne" aria-expanded="false" aria-controls="collapseOne">
Getting Started
<span class="glyphicon glyphicon-menu-right" aria-hidden="true"></span></a></h4>
</div>
<div id="collapseOne" class="panel-collapse collapse" role="tabpanel" aria-labelledby="headingOne">
<div class="panel-body">
<a id="choosing">Choosing a topic</a>
<a id="exploring">Exploring a topic</a>
</div></div>
JQuery
$(document).ready(function () {
$('div.collapse').on("show.bs.collapse || hide.bs.collapse", function () {
let glyph = $(this).siblings("div.panel-heading").find('span.glyphicon');
glyph.hasClass("glyphicon-menu-right") ? glyph.toggleClass("glyphicon-menu-down") : glyph.toggleClass("glyphicon-menu-right");
});
});

UI-Bootstrap Collapse doesn't reset on new route

Working example: http://executionists.com (view in mobile viewport to see the problem)
I'm using the collapse directive from UI Bootstrap and it works great to toggle my menu on/off. However, when I click a menu item, I'm routed to a new view (which is what it should do) but then the menu stays open. It actually flashes for a second as it appears to be collapsing but then springs back open and wont collapse until manually done.
HTML:
<button type="button" class="btn btn-default" ng-click="isCollapsed = !isCollapsed">
<i class="fa fa-bars fa-4"></i>
</button>
<div class="container mobile-menu visible-xs collapse" collapse="isCollapsed">
<a ng-href="#/about">About</a>
</div>
In the relevant controller, I simply set a default state:
$scope.isCollapsed = true;
What am I missing?
Try adding something like this if I understand that this is want you need
$("div.container.mobile-menu.visible-xs.collapse div.row div.col-1 ul a").click(function() {
if (window.location.hash) {
$('.mobile-menu').height(0); //change the menu to be 'Hidden'
}
});
UPDATE
$("div.container.mobile-menu.visible-xs.collapse div.row div.col-1 ul a").click(function() {
$('.mobile-menu').toggle(function() {
if (window.location.hash) {
$('button.btn.btn-default').click();
}
});
});

How to hide my collapse bootstrap 3 navbar with click on body when, collapse is visible?

I'm making a WordPress website for agency where I will go work.
I used Bootstrap 3.0, and I created a responsive menu.
How to hide menu when is collapsed and visible (2nd pic) with click on body, and menu button change it color only collapse is visible?
bootstrap.js and jquery is connected in my footer.
This is a functional solution:
$(document).on('click touchstart', function (e) {
if ($(e.target).closest(".navbar-collapse").length === 0 && $(e.target).closest('[data-target=".navbar-collapse"]').length === 0) {
$(".navbar-toggle").collapse('hide');
}
});
Try This Example
<script type='text/javascript'>
$(document).ready(function () {
function CloseNav() {
$(".navbar-collapse").stop().css({ 'height': '1px' }).removeClass('in').addClass("collapse");
$(".navbar-toggle").stop().removeClass('collapsed');
}
$('html').click(function (event) {
var clickover = $(event.target);
var _opened = $(".navbar-collapse").hasClass("navbar-collapse in");
if (_opened === true && !clickover.hasClass("navbar-toggle")) {
CloseNav();
}
});
});
</script>
Update
you can change the html selector to whatever selector you want, body (if you have enough height), wrapper or whatever. A clean fiddle example here
This works. It will close the collapsed navbar when touched anywhere on the mobile touchscreen.
$(document).on('touchend', function (event) {
var clickover = $(event.target);
var $navbar = $(".navbar-collapse");
var _opened = $navbar.hasClass("in");
if (_opened === true && !clickover.hasClass("navbar-toggle")) {
$navbar.collapse('hide');
}
});
Here is another approach which is working for me.
My scenario: I want to hide the collapsible when I click anywhere outside of a form which contains a dropdownlist.
$(document).ready(function(){
//check if collapsible is shown
$(".collapse").on('shown.bs.collapse', function(){
//then check if there was a click
$(document).click(function(event) {
//exclude the click was on the form
if (!$(event.target).hasClass("input-default")) {
//then hide it
$(".collapse").collapse('hide');
}
});
});
});
I think your best approach would be to do something in a mediaquery, or pherhaphs with js instead, check in bootstrap page which are the break points and use the one you are interested in.
You don't want to listen for the click all the time that is so wrong. you have to bind and unbind based on the navbar status. here is my navbar-colapse and it's id is 'z', and when it is open i will listen for clicks and when it's closed i don't listen anymore. i will put comment on the code:
//CALLBACK AFTER NAVBAR-COLLAPSE OPEN
$('#z').on('shown.bs.collapse', function () {
// HERE WE BIND THE CLICK TO THE HANDLER FUNCTION
$(document).bind( "click", handler );
})
//CALLBACK AFTER NAVBAR-COLLAPSE CLOSE
$('#z').on('hidden.bs.collapse', function () {
// SINCE THE NAVBAR IS CLOSED WE DONT NEED TO LISTEN FOR CLICKS ANYMORE
$(document).unbind( "click", handler );
})
//THIS IS THE FUNCTION THAT GET FIRED
var handler = function() {
//LISTEN FOR CLICKS
$(document).click(function(event) {
//HERE FORM-CONTROL IS MY SEARCH BOX IN THE NAV SO I DONT WANT TO CLOSE
//THE NAVBAAR IF THEY CLICK ON FONT-CONTROL, BUT ANYTHING BESIDE THAT WE CLOSE THE NAVBAR
if (!$(event.target).hasClass("form-control")) {
$('#z').collapse('hide');
}
});
};
Also here is my nav-bar code :)
<nav class="navbar navbar-default my-nav" data-spy="affix" id="nav" style="margin-bottom: 0">
<div class="container-fluid">
<div class="navbar-header">
<button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#z" aria-expanded="false">
<span class="sr-only">Toggle navigation</span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
</button>
<a class="navbar-brand" href="#">-</a>
</div>
<!-- Collect the nav links, forms, and other content for toggling -->
<div class="collapse navbar-collapse" id="z">
<div class="navbar-form navbar-left my-navbar-left" role="search">
<div class="form-group">
<input id="searchbar" type="text" class="form-control" placeholder="Search for ads">
</div>
</div>
<ul class="nav navbar-nav navbar-right my-navbar-right">
<li><a class="tab-c tab-home"> <span class="text-to-icon">Posts</span> </a></li>
</ul>
</div><!-- /.navbar-collapse -->
</div><!-- /.container-fluid -->
</nav>
$('.collapse').collapse('hide');
