I decided to go ahead and update my site to the latest version of Bootstrap, version 5.0 and am having difficulty getting modals to work. Reading the migration guide said nothing about breaking modals and my site worked perfectly before. My code uses javascript/jQuery to fire off the modal after the ajax loads the text. The ajax part still works fine, but it's not firing the modal after it retrieves it. I'm using the latest bootstrap.bundle.min.js.
$( document ).ready(function() {
$('.hourModal').click(function(){
var obj_id = $(this).data('id');
$.ajax({
url: 'ajax-multi.php',
type: 'POST',
data: {obj_id: obj_id,role:'some_role'},
//dataType: 'html',
success: function(response){
$('.modal-body').html(response);
//$('#hourModal').modal('show'); //Old way that worked great
var hourModal = new bootstrap.Modal(document.getElementById('hourModal'));
hourModal.show(); // New way I tried from the Bootstrap documentation
}
});
});
});

UPDATE:
As described below, I had to move bootstrap.min.js to the end of the page, after </body> and leave where I call jquery.min.js at the top in the header. Anyone have any idea why it has to be done this way?
Move your <script> with bootstrap at the end of the <body>. It fixed my Bootstrap 5 modal issue.
This issue is fixed in currently available 5.0.1
UPDATE:
Fixed in Bootstrap 5.0.1
I had the same problem. The only difference I use Webpack to build.
If you want to load your scripts from head section you can try to add async option.
This fixed the issue for me.
<script src="..." async="async"></script>
I had the same problem. I called jquery.js and bootstrap.js at the end of the html and before /body and it worked correctly.
mamantoha's suggestion seems to be the better way to handle this since it doesn't require moving the outside the section, and some people may have dependencies that require bootstrap to be loaded ahead of other scripts in the section.
In bootstrap 4 or 5 you maybe forgetting the '#' in
data-bs-target="#exampleModal"
I am in the process of learning jQuery and JS, so I apologize if this is a stupid, easy question.
I am working with a tour plugin called intro.js that adds hints to a web page (bootstrap page). I got the intro.js hints working, however I need to be able to show and hide all of the hints by toggling one button. The way the plugin currently works, you show the hints by clicking a button, then you have to manually click on each hint icon to view the tooltip, then click a button on the tooltip to hide the hint icon. The web pages could have several hints displayed (anywhere from 10-15) and users may not want to see what all hints are, as they may want to just see what 1 or 2 are then close all the hints - so I want to be able to toggle all of them on/off with one button.
According to the plugin API (view it here: https://introjs.com/docs/hints/api/), the hints are added when the button is clicked using this function: introJs.addHints(). You are supposed to be able to hide all of the hints using this function: introJs.hideHints().
So, how can I toggle both of these functions with one button?
Also, another issue I am having is if a user does not close all of the hint icons and they open a new page, the hint icons are still visible. If I refresh the page, they disappear. Related to this, if someone opens the hints and closes them, but decides to reopen the hints again, they do not open unless the page is refreshed. The API documentation has a function called: introJs.refresh() that says it refreshes and rearranges the hints. I think this is what I need to clear the existing hints (but I could be wrong). How can I clear/refresh the hints when the hints are closed so users can reopen the hints if needed, without refreshing - and so the hints disappear if a new page is opened and some hints were not closed.
Please help me with these questions and make a newbie's Christmas/holiday even better!!!
Here is a jsfiddle with hints added to a bootstrap modal. The Show Hints link is what I need to toggle on/off: http://jsfiddle.net/beaver71/fc0rkakn/
Thank you to everyone reading - and Happy Holidays to all of you.
Sample HTML:
<!-- Button trigger modal -->
Open Notes Modal
<!-- Modal -->
<div class="modal fade" id="notesModal" tabindex="-1" role="dialog" aria-labelledby="notesModalLabel">
<div class="modal-dialog" role="document">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">×</span></button>
<h4 class="modal-title" id="myModalLabel">Notes</h4>
</div>
<div class="modal-body">
<div id="note-input" data-hint="Input your notes here." data-hintposition="top-middle" data-position="bottom-right-aligned">
<input type="text" name="note" class="col-md-11" maxlength="300"/><button id="add-note" data-hint="Select Add button to save and add your notes." data-hintposition="top-middle" data-position="bottom-right-aligned">Add</button>
</div>
</div>
<div id="note-total" data-hint="Track your remaining characters here." data-hintposition="top-middle" data-position="middle-right" style="margin-left:15px;">0/300
</div>
<div><a class="btn btn-tour" href="javascript:void(0);" onclick="javascript:introJs().addHints();"><i class="fa fa-bus"></i> Show Hints</a></div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
<button type="button" class="btn btn-primary">Save changes</button>
</div>
</div>
</div>
</div>
The API allows introJs to be commanded and for callbacks to be attached to various internal events, however it doesn't provide for inspection of state (in particular whether or not a hint is currently showing).
To achieve the toggle function, you will need to manage a state variable of your own.
Something like this ...
jQuery(function($) {
var hintShowing = false; // a variable by which to track the state of introJs.
introJs("#targetElment");
$("#myToggleButton").on('click', function() {
if(hintShowing) {
introJs.hideHints();
hintShowing = false;
} else {
introJs.showHints();
hintShowing = true;
}
});
function setShowing() {
hintShowing = true;
}
function resetShowing() {
hintShowing = false;
}
introJs.onchange(setShowing).oncomplete(resetShowing).onexit(resetShowing);
// add hints and set options here
});
That should work, at least to a certain extent. It depends on whether onchange fires when the initial hint is shown. If not, setShowing() will also need to be called manually (from your own code when the hint sequence starts) or maybe just initialise var hintShowing = true;
I have multiple bootstrap dialog divs in one single jsp.
Dialog divs look like below
<div id="manage-notes-dialog" class="modal fade" role="dialog">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<h3 id="about">NOTES <input name="backButton" type="button" value="⇚ " class="btn btn-primary pull-right" /></h3>
</div>
<div class="modal-body">
.......UI HTML.........
.......UI HTML.........
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
</div>
</div>
</div>
</div>
In my jquery button clicks I was opening the dialogs as below
$("#manage-notes-dialog").modal('show');
Above command being part of jquery click action for button
I am changing my UI handling from jQuery to angularjs.
After writing the angularjs controller and testing it I wrote below code to open the above dialogs.
$scope.openNotes = function() {
$("#manage-notes-dialog").modal('show');
};
This still not completely using angularjs as $("#manage-notes-dialog").modal('show'); is still jQuery and stops when I remove the jquery js.
I wanted to know if I can have the bootstrap modal dialogs opened through angularjs. I want to avoid to re-write all modal dialog from scratch while using angularjs as a lot of data is being loaded via JSTL. I am pretty new to angularjs And doing what has been said in this “Thinking in AngularJS” if I have a jQuery background? not that simple
Please suggest possible workaround/solution steps. Most of the solution/examples I have found are completely using angularjs modal directive. or individual html.
My constraint is that I want to keep all the dialogs in one single jsp as they would be common to multiple UI pages
I went by what Matthew Green suggested in his comment
.
Using ng-template I generated div and loaded it via angularjs uibModal open call. Wrote a separate controller dialogController which will handle all actions and scope variable and actions used by my Modal div.
Below is the javascript call I used to open the div from the template cache.
var modalInstance = $uibModal.open({
templateUrl: 'error-dialog',
controller: 'dialogController',
scope: $scope,
resolve: {
msg: function(){
return 'ErrorMessage for DIsplay';
}
}
});
The div element inside the javascript looks below
<script type="text/ng-template" id="error-dialog">
<div class="modal-body alert-danger">
<button type="button" class="btn btn-default pull-right" data-dismiss="modal" ng-click="close()">⤫</button>
<pre class="alert-danger" style="border:0px;">{{msg}}</pre>
</div>
</script>
And finally the controller
.controller('dialogController', [ '$scope','msg','$uibModalInstance' ,function($scope, msg,$uibModalInstance) {
$scope.msg = msg;
$scope.close = function() {
$uibModalInstance.dismiss('cancel');
};
} ])
I'm not sure why but all the modal functions are not working with me.
I checked the version and the load they are fine.
I keep getting this error message:
Uncaught TypeError: $(...).modal is not a function
for the hide I already found an alternative.
instead of:
$('#myModal').modal('hide');
I used this :
$('#myModal .close').click();
And it works perfectly.
The problem now is with the show
$('#myModal').modal("show");
I also tried both
$('#myModal').modal("toggle");
And:
$('#myModal').modal();
but unfortunately none of them is working.
Here html code -when the button is clicked I will do some verification and handle a json data from the web service if it succeed then I want show my modal- everything is working except the show.
<button type="button" id="creatNewAcount" class="btn btn-default" data-toggle="modal">Sign up</button>
if there's any alternative I would like to know it.
Most common reason for such problems are
1.If you have defined the jquery library more than once.
<script type="text/javascript" src="//code.jquery.com/jquery-1.11.3.min.js"></script>
<script src="http://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/js/bootstrap.min.js"></script>
<div class="modal fade" id="myModal" aria-hidden="true">
...
...
</div>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.0/jquery.min.js"></script>
The bootstrap library gets applied to the first jquery library but when you reload the jquery library, the original bootstrap load is lost(Modal function is in bootstrap).
2.Please wrap your JavaScript code inside
$(document).ready(function(){});
3.Please check if the id of the modal is same
as the one you have defined for the component(Also check for duplication's of same id ).
<div class="modal fade" id="myModal" aria-hidden="true">
...
...
</div>
Note: Remove fade class from the div and enjoy it should be worked
This can happen for a few reasons:
You forgot to include Jquery library in the document
You included the Jquery library more than once in the document
You forgot to include bootstrap.js library in the document
The versions of your Javascript and Bootstrap does not match. Refer bootstrap documentation to make sure the versions are matching
The modal <div> is missing the modal class
The id of the modal <div> is incorrect. (eg: you wrongly prepended # in the id of the <div>)
# sign is missing in the Jquery selector
I got same issue while working with Modal Popup Bootstrap , I used Id and trigger click event for showing and hidding modal popup instead of $("#Id").modal('show') and $("#id").modal('hide'),
`
<button type="button" id="btnPurchaseClose" class="close" data dismiss="modal" aria-label="Close"> <span aria-hidden="true">×</span></button>
<a class="btn btn-default" id="btnOpenPurchasePopup" data-toggle="modal" data target="#newPurchasePopup">Select</a>
$('#btnPurchaseClose').trigger('click');// for close popup
$('#btnOpenPurchase').trigger('click');`// for open popup
My root cause was that I forgot to add the # before the id name. Lame but true.
From
$('scheduleModal').modal('show');
To
$('#scheduleModal').modal('show');
For your reference, the code sequence that works for me is
<script>
function scheduleRequest() {
$('#scheduleModal').modal('show');
}
</script>
<script src="<c:url value="/resources/bootstrap/js/bootstrap.min.js"/>">
</script>
<script
src="<c:url value="/resources/plugins/fastclick/fastclick.min.js"/>">
</script>
<script
src="<c:url value="/resources/plugins/slimScroll/jquery.slimscroll.min.js"/>">
</script>
<script
src="<c:url value="/resources/plugins/datatables/jquery.dataTables.min.js"/>">
</script>
<script
src="<c:url value="/resources/plugins/datatables/dataTables.bootstrap.min.js"/>">
</script>
<script src="<c:url value="/resources/dist/js/demo.js"/>">
</script>
Use .modal({show:true}) and .modal({show:false}) instead of ('show') and ('hide') ... it seems to be bootstrap / jquery version combination dependent. Hope it helps.
the solution of 'bootstrap modal is not opening' is, put your Jquery CDN first in the head tag (after starting head tag).
I wasted two days in finding this problem.
Please,
try and check if the triggering button has attribute type="button".
Working example:
<button type="button" id="trigger" style="visibility:visible;" onclick="modal_btn_click()">Trigger Modal Click</button>
<!-- Modal -->
<div class="modal fade" id="myModal" role="dialog">
<div class="modal-dialog modal-sm">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal">×</button>
<h4 class="modal-title">Modal Header</h4>
</div>
<div class="modal-body">
<p>This is a small modal.</p>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
</div>
</div>
</div>
</div>
<script >
function modal_btn_click() {
$('#myModal').modal({ show: true });
}
</script>
Try This without paramater
$('#myModal').modal();
it should be worked
are you sure that the id of the modal is "myModal"? if not then the call will not trigger it.
also - just from reading your post - you are triggering a function / validation with this button
<button type="button" id="creatNewAcount" class="btn btn-default" data-toggle="modal">Sign up</button>
and then if all is well - you want to trigger the modal. - if this is hte case - then you should remove the toggle from this button click. I presume you have an event handler tied to this click? you need the .modal("show") as a part of that function. not toggled from this button. also - is this id correct "creatNewAcount" as opposed to this spelling "createNewAccount"
<button type="button" id="creatNewAcount" class="btn btn-default" >Sign up</button>
use the object to call...
<a href="#" onclick='$("#myModal").modal("show");'>Try This</a>
or if you using ajax to show that modal after get result, this is work for me...
$.ajax({ url: "YourUrl",
type: "POST", data: "x=1&y=2&z=3",
cache: false, success: function(result){
// Your Function here
$("#myModal").modal("show");
}
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js"></script><script type="text/javascript" src="//code.jquery.com/jquery-1.11.3.min.js"></script>
the first googleapis script is not working now a days use this second scripe given by jquery
jQuery lib has to be loaded first. In my case, i was loading bootstrap lib first, also tried tag with target and firing a click trigger. But the main issue was - jquery has to be loaded first.
Please also make sure that the modal div is nested inside your <body> element.
After trying everything on the web for my issue, I needed to add in a small delay to the script before trying to load the box.
Even though I had put the line to load the box on the last possible line in the entire script. I just put a 500ms delay on it using
setTimeout(() => { $('#modalID').modal('show'); }, 500);
Hope that helps someone in the future. 100% agree it's prob because I don't understand the flow of my scripts and load order. But this is the way I got around it
In my case, bootstrap.css and bootstrap.js versions are mismatched.
It is working if I remove the fade class. But the background is disappeared.
I added the same version of bootstrap files. Now it is working perfectly.
Thank you #Mohammed Shareef C.
Another use case that may be the cuplrit
My problem was that I had a jquery selector that was using a variable that was not assigned immediately.
My modal had a dynamic ID
<div class="modal fade" id="{{scope.modalId}}"... >
This is in angularJS, so the valud of scope.modalID wasn't being bound until $scope.onInit
vm.$onInit = function () {
$( `#${vm.modalId}` ).on('shown.bs.modal', function(){
console.log('WORKS')
});

Make sure your script tag is closed with another script tag like below
before
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"/>
After
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
I want to check for mozGetUsermedia in browser and if its not there return an alert.
I am using Twitter bootstrap Alert JS for the effect
and JS code to check the condition.
But my DOM seems to be broken and even though the condition is false the message is shown.
HTML Code
<div id="gum" >
<div class="alert alert-block alert-error fade in">
<button type="button" class="close" data-dismiss="alert">×</button>
<h4 class="alert-heading">mozGetUserMedia is missing</h4>
<p>Do you have the latestNightly and set
<i>media.navigator.enabled</i> to true?
</p>
</div>
</div>
JS Code
if (!navigator.mozGetUserMedia) {
document.getElementById("gum").style.display = "block";}
you need to hide it by default
<div id="gum" class="hide">
Since you are using jQuery
$(function(){
if (!navigator.mozGetUserMedia) {
$("#gum").show();
}
});
