I'm hoping someone has done this before and has some guidance.
I'm using bootstrap on a site, and right now I have a working modal that loads in a set of pictures, currently 2. This works fine and I have them linked with anchor tags.
However, I'm trying to find the best way to take the selection of the image and once the user clicks it, apply it to the background image css for the container.
SO right now I just have a test image for the background, but basically I want the selection of an image from the modal to create a bgImg variable, so to speak, and apply it to the background of my container div in real time. So this should apply some javascript, but I don't really know what specifically to use. Or for that matter, how to create a variable from the selection and then apply it to CSS.
Basically if I select image 1 from the modal, the modal should close and image one's URL should now take the place of the CSS for the background image url, if that makes sense
CSS for the background in question:
.my-container>.middle {
flex-grow: 1;
padding:30px;
background-image: /*this would be the bgImg for the href*/;
background-size: cover;
}
HTML for the modal and the images that I want to apply to the background
Choose Page Background
<div class="modal fade" id="exampleModal" tabindex="-1" role="dialog" aria-labelledby="exampleModalLabel" aria-hidden="true">
<div class="modal-dialog" role="document">
<div class="modal-content">
<div class="modal-header">
<h5 class="modal-title" id="exampleModalLabel">Choose an image:</h5>
<button type="button" class="close" data-dismiss="modal" aria-label="Close">
<span aria-hidden="true">×</span>
</button>
</div>
<div class="modal-body">
<img style="width: 200px; height: 200px;" src="images/bg_orange.svg">
<img style="width: 200px; height: 200px;" src="images/bg_green.svg">
</div>
<div class="modal-footer">
<button type="button" class="btn btn-secondary" data-dismiss="modal">Close</button>
<button type="button" class="btn btn-primary">Save changes</button>
</div>
</div>
</div>
</div>
UPDATE:
adding JS
<script type="text/javascript">
const images = document.querySelectorAll('some-image-selector');
images.forEach(img => img.addEventListener('click', setBackground));
function setBackground(e) {
const container = document.querySelector('.my-container > .middle')
container.style.background = `url(${e.target.src}) center center no-repeat`
};
</script>
So to make this work, you'll want to add a click event listener to each image.
const images = document.querySelectorAll('some-image-selector')
images.forEach(img => img.addEventListener('click', setBackground))
something along those lines ^^
Then within setBackground, update the css
function setBackground(e) {
const container = document.querySelector('.my-container > .middle')
container.style.background = `url(${e.target.src}) center center no-repeat`
}
You'll have to do this with Javascript. In jQuery:
//prevent default action
$('.modal-body a').click(function(e) {
e.preventDefault();
});
$('.modal-body img').on('click', function(e){
//store the target url in a variable
let source = $(this).attr('src');
console.log(source);
//set the user-selected image to the proper spot on the page
$('.my-container > .middle').attr('src', source);
//now close the modal
closeModal();
});
function closeModal(){
$('#exampleModal').hide();
}
You can tweak how you want to close the modal by using a function like slideToggle() instead of hide().
I am using bootstrap4 alpha 6 Modal, I am getting:
Error: Modal is transitioning
That happen when I am trying to re-trigger the same modal again with dynamic data through JavaScript function as following:
function openModal(title, text) {
$('.modal-title').text(title);
$('.modal-body p').text(text);
$('#modalAlert').modal('show');
}
I tried to use setTimeout function, but didn't work as in this article:
https://github.com/twbs/bootstrap/issues/21687
Any suggestions?
The quickest solution is to remove the modal 'fade' class which is throwing this error. It seems to be a known issue of the Bootsrap v6 that will be fixed in a next released.
See here
Worked with removing fade from parent div class.
Final Modal code ( Adding here for posterity ) :
HTML
<div class="modal loadingModal" id="applemodal" tabindex="-1" role="dialog" aria-labelledby="exampleModalLabel" aria-hidden="true">
<div class="modal-dialog" role="document">
<div class="modal-body">
<div class="row">
<div class="col-md-6">
</div>
<div class="col-md-6">
<img src="ico/4.svg">
</div>
</div>
</div>
</div>
</div>
JS
$.ajax({
type: "GET",
url: "/getTimeline",
data: {
'dateTime': selected
},
async: true,
beforeSend: function () {
$('#applemodal').modal({
backdrop: 'static',
keyboard: false
});
},
success: function(data) {
$('#applemodal').modal('toggle');
}
});
i am using bootstrap 4 Modal too, My solution;
$(document).on('show.bs.modal', '.modal', function (event) {
var zIndex = 1040 + (10 * $('.modal:visible').length);
$(this).css('z-index', zIndex);
setTimeout(function() {
$('.modal-backdrop').not('.modal-stack').css('z-index', zIndex - 1).addClass('modal-stack');
}, 0);
});
First open the modal and then try to find the DOM elements that's inside modal (eg. $('.modal-title') and $('.modal-body p'))
Changing the order of executing your function might work:
function openModal(title, text) {
$('#modalAlert').modal('show');
$('.modal-title').text(title);
$('.modal-body p').text(text);
}
Finally, make sure that modal is open/visible in the screen when you access HTML that's inside the modal.
Please set your button type='submit' to type='button'
My solution was to open the model programmatically rather than through the link.
Instead of:
Open My Modal
Use:
Open My Modal
$('#myLink').on('click', function(){
$('#myModal').modal('show');
})
Bootstrap modal hide is not working. Alert comes in else. but my modal is not hidden Added bootply. My issue is the same one.
<button class="button primary" id="buy" data-toggle="modal" data-target=".bs-example-modal-sm" style= "text-decoration:none;" type="button">Review and confirm</button>
<div class="modal-bootstrap fade bs-example-modal-sm" id="myModal" tabindex="-1" role="dialog" aria-labelledby="smallModalLabel" aria-hidden="true">
<div class="modal-bootstrap-dialog modal-sm">
<div class="modal-bootstrap-content">
<div class="modal-bootstrap-body">
-- content ----
</div>
</div>
</div>
<div class="modal-bootstrap-footer">
<button type="submit" class="button primary" data-dismiss="modal">Close</button>
<button type="submit" class="button primary">Save changes</button>
</div>
</div>
<script type="text/javascript">
$("#buy").click(function () {
var a = 4;
if (a == 5) {
alert("if");
$('#myModal').modal('show');
}
else {
alert("else");
$('#myModal').modal('hide');
}
});
</script>
bootply
You are using both modal toggling methods: via Javascript and via data attributes. So your click is firing the modal show as your data attributes set, and your Javascript does not affect this trigger.
Just remove the data attributes and go with the Javascript method:
<button class="button primary" id="buy" style="text-decoration:none;" type="button">Review and confirm</button>
<div class="modal-bootstrap fade bs-example-modal-sm" id="myModal" tabindex="-1" role="dialog" aria-labelledby="smallModalLabel" aria-hidden="true">
<!-- modal contents -->
</div>
<script type="text/javascript">
$("#buy").click(function () {
var a = 4;
if (a == 5) {
alert("if");
$('#myModal').modal('show');
} else {
alert("else");
$('#myModal').modal('hide');
}
});
</script>
I had same problem. Remove fade class.
I had the same problem, tried a lot of things but the only solution that worked for me is #Tang Chanrith suggested to remove individually parts of the modal but a little bit improved to place back and the scrollbar. I'll put my answer just if the accepted answer did not work for them. Sorry for my english. Hope I helped.
#Tang Chanrith
Try this function
function hideModal() {
$("#myModal").removeClass("in");
$(".modal-backdrop").remove();
$("#myModal").hide();
}
Improved Sollution
You just have to delete a class from body and css that generated
function hideModal() {
$("#myModal").removeClass("in");
$(".modal-backdrop").remove();
$('body').removeClass('modal-open');
$('body').css('padding-right', '');
$("#myModal").hide();
}
For those still having issues (hi Googlers!), if you're using fade, you'll have to use javascript to remove fade class.
Try this function
function hideModal(){
$("#myModal").removeClass("in");
$(".modal-backdrop").remove();
$("#myModal").hide();
}
Remove the modal class "fade" will do.
I have solution this problem.
$('#landingpage, body').on('click',function(){
$( ".action-close" ).trigger( "click" );});
try to add return false like this:
$("#buy").click(function () {
var a = 4;
if (a == 5) {
alert("if");
$('#myModal').modal('show');
}
else {
alert("else");
$('#myModal').modal('hide');
}
return false;
});
I checked your code.
Now you compare a == 5. but a is always 4. you may have to check this why you are doing this comparison.
Also you need you remove the data-target if you want to open modal from javascript :
<button class="button primary" id="buy" data-toggle="modal" style="text-decoration:none;" type="button">Review and confirm</button>
data-target directly opening the modal.
Check if this is working.
You should try this $('.modal.in').modal('hide')
Via https://github.com/twbs/bootstrap/issues/489
I had the same problem, my mistake was that I was trying to open the modal window a few times. We must test that the modal window is not already open before trying to open it.
if (!($("#MyModal").data('bs.modal') || {})._isShown){
$("#MyModal").modal('show');
}
Hide modal dialog box using bootstrap
Method 1: using bootstrap
$('.close').click();
$("#MyModal .close").click();
$('#myModalAlert').modal('hide');
Method 2: using stop-propagation
$("a.close").on("click", function(e){
$("#modal").modal("hide");
e.stopPropagation();
});
Method 3: After shown method invoke
$('#myModal').on('shown', function () {
$('#myModal').modal('hide');
})
Method 4: Using CSS
this.display='block'; //Set block css
this.display='none'; //set none css after close dialog
In the java script code you need to add one line of code
$("#savechanges").on("click", function (e) {
$("#userModal").modal("hide");
e.stopPropagation(); //This line would take care of it
});
As I encountered, sometimes you need to remove display style:
style="display: block;"
I had the same issue. I tried the JavaScript way suggested in the post, unfortunately it only worked half of the time. If I triggered my modal a few times, it bugs out. As a result I created a work around using CSS:
/* Hide the back drop*/
.modal-backdrop.show {
display: none;
}
/* Simulate the backdrop using background color */
.modal-open .modal {
background-color: rgba(47, 117, 19, 0.3);
}
I was opening the modal popup when I click on the link using data-toggle="modal" attribute which was bound with that link and trying to close it using javascript but I was failed each time, so when I remove the "data-toggle" attribute and "href" from that link and opened it using javascript then it was closing properly using javascript as well.
from the below few lines of code, you can understand easily
Advanced Search
I changed the above link to something link this
Advanced Search
After that when I try to close it using javascript, then I become successful
$("#CustomerAdvancedModal").modal('hide');
I am also having the same problem, where I can't find the correct solution for it.
Later I observed that what is happening when the modal gets closed when it works well.
Three Main properties are,
modal-open class gets removed from <body> tag.
In <body> tag change CSS .
<div> class of modal-backdrop gets removed.
So, When u do these things manually, you will achieve it, when not works.
The code should be as following in Jquery,
$('body').removeClass('modal-open');
$('body').css('padding-right', '');
$(".modal-backdrop").remove();
$('#myModal').hide();
Hence, try this and get a solution.
Before you open a loading modal, make sure that you close all others.
This is the function is use to close the modal:
function hideLoadingModal() {
$('#loadingModal').on('shown.bs.modal', function () {
$('#loadingModal').modal('hide');
});
}
Now if I want to open the modal I call the above function and open a new one after that.
Like this:
hideLoadingModal();
$('#loadingModal').modal('show');
Hope this helps you.
Cheers
One possible reson should be the order of jquery and bootstrap and your script is not in proper sequence.
Below should be the sequence.
1. <script src='js/jquery-3.2.1.min.js'></script>
2. <script src='js/bootstrap.min.js'></script>
3. your own script:
<script type="text/javascript">
$("#buy").click(function () {
var a = 4;
if (a == 5) {
alert("if");
$('#myModal').modal('show');
}
else {
alert("else");
$('#myModal').modal('hide');
}
});
</script>
Check if you closed all nested div inside main modal div
<div data-backdrop="static" class="modal fade" id="modal-progress" tabindex="-1" role="dialog" aria-labelledby="exampleModalCenterTitle" aria-hidden="true">
-----NESTED DIV ------------------
</div>
None of the above solutions worked for me. If this is your case, try to imitate click event on the close button (the one which is added dynamically):
<div class="modal" tabindex="-1" role="dialog" id="modal" area-hidden="true" style="display: inline-block;">
<div class="modal-dialog modal-dialog-centered" role="document">
...
</div>
Close</div>
</div>
$('.close-modal').click() should resolve the issue.
Try this
give an id to close button
<button type="submit" id="modalcloseBtn" class="button primary" data-dismiss="modal" >Close</button>
and trigger onclick event
$('#modalcloseBtn').trigger("click");
G.modals = [];
/**
*
* #param {
* modalId: string,
* callback: function
* } options
* #returns
*/
const openModal = (options) => {
const {
modalId = false,
callback = () => { }
} = options;
if (!modalId) return;
const modalNode = document.querySelector(`#${modalId}`);
modal = new bootstrap.Modal(modalNode);
modal.show();
const modalObject = {
modal,
id: modalId
};
G.modals.push(modalObject);
callback();
};
/**
*
* #param {
* modalId: string,
* callback: function
* } options
* #returns
*/
const closeModal = (options) => {
const {
modalId = false,
callback = () => { }
} = options;
if (!modalId) return;
const currentModal = G.modals.find(item => item.id === modalId) || false;
if(!currentModal) return;
const { modal } = currentModal;
const { _element, _backdrop } = modal;
_element.classList.remove('show');
_backdrop._element.remove();
G.modals.splice(G.modals.indexOf(currentModal), 1);
callback();
};
openModal({
modalId: 'your-modal-id',
callback: () => {
DoSomethingAfterModalOpened();
}
});
closeModal({
modalId: 'your-modal-id',
callback: () => {
DoSomethingAfterModalClosed();
}
});
if nothing helps (that happens) - make sure that nobody prevents it like below (my case):
$modal.on('hide.bs.modal', function (e) {
if (shouldNotBeClosed) {
return e.preventDefault();
}
});
Same issue here for no reason, i'm not using "fade" stuff.
I open modal and close modal only with js, the hide function is working only when called inside a setTimeout.
<script>
var modal_show = function(){
$("#modal_post").modal("show");
};
var modal_hide = function(){
$("#modal_post").modal("hide");
};
window.addEventListener("message", function(event){
// listening iframe post message
modal_hide();
});
</script>
<div class="modal" id="modal_post" tabindex="-1" role="dialog" style="width: 100%;" data-keyboard="false" data-backdrop="static">
<div class="modal-dialog" style="width: 450px; height:600px; background: white; border: none; box-shadow: none;" role="document">
<div class="modal-content" style="width: 100%; background: white; border: none; box-shadow: none;">
<div class="modal-body" style="width: 100%; background: white; border: none; box-shadow: none; padding: 0;">
<div>
<iframe src="https://perdu.com" style="width:450px;height:600px;"></iframe>
</div>
</div>
</div>
</div>
</div>
For no reason, modal_hide(); is working inside the console but not in my code.
If i replace the modal_hide(); in the event listener with setTimeout(modal_hide, 200); it's working properly
its very easy.. Remove fade class :)
What I'm trying to do is to add to a custom message box a time function to keep the message box hidden for x amount of time, but only when the user click on the appropriate button. (dismiss)
I'm trying to take advantage of bootstrap but now I think I need some jquery code as well.
this is what I 'm using to show the message:
<div class="notifier-box">
<div class="custompm fade" id="message1">
<p> {L_YOU_HAVE} {PRIVATE_MESSAGE_INFO</p>
<button data-dismiss="alert" class="btn btn-small">{L_DISMISS}</button>
</div>
</div>
with this function:
<script>
head.ready(function () {
// some callback stuff
$('#message1').toggleClass('in');
});
</script>
First you check the correct implementation of Bootstrap Alerts (some examples here):
<div class="alert alert-warning fade in" id="message1">
<button type="button" class="close" data-dismiss="alert" aria-hidden="true">×</button>
<strong>Holy guacamole!</strong> Best check yo self, you're not looking too good.
</div>
Using jQuery you need to setup a timer to auto dismiss alert box, and bind an event to the button who will dismiss the alert with a click:
$(function(){
setInterval(function(){
$("#message1").alert('close');
},3000); // milliseconds to auto dismiss
$("#button_dismiss").on('click', function(){
$("#message1").alert('close');
});
});
Update: According to your comments:
<div id="message1">I am an alert!</div>
<script>
$(function(){
// Set a global timeout handler
var timeoutHandle = window.setTimeout(function(){
$("#message1").addClass('hide');
}, 2000);
$("#some-button").on('click', function(){
// Clear current timeout
window.clearTimeout(timeoutHandle);
$("#message1").removeClass('hide');
timeoutHandle = window.setTimeout(function(){
$("#message1").addClass('hide');
}, 2000);
});
});
</script>
My requirement is that I need to show a modal window as a form to be filled by user. But the height of that modal should be not more then window size.
So if the entries in form are too much then the modal becomes scrollable. The problem is that while validating the entries in the form the error message is shown at the top of the modal above the first entry. If user is at last property then he will not be knowing that some validation error had occurred unless the modal is scrolled to top on the error event.
I have tried :
$(window).scrollTop();
// and
$('#modalId').scrollTop();
this is the modal code:
<div class="modal hide" id="groupModal" tabindex="-1" role="dialog" aria-hidden="true" >
<div class="modal-header">
</div>
<div class="modal-body" style="max-height: 300px;">
<div class="grpForm">
<div class="alert alert-error hide">
<span class="errMsg"></span>
</div>
<div class="alert alert-success hide">
<span class="successMsg"></span>
</div>
<form class = "formFieldHolder" id="groupInfoForm"></form>
</div>
</div>
<div class="modal-footer">
<button class="btn cancelFormBtn" data-dismiss="modal" aria-hidden="true" msgkey="common.cancel.label"></button>
<button class="btn btn-primary submitGroupFormBtn" type="submit" msgkey="common.submit.label"></button>
</div>
</div>
$('#modalId').scrollTop(0);
scrollTop() only returns the value; scrollTop(0) sets the value to 0 (all the way to the top)
To scroll the page to the modal, select html, body and scroll to the offset top of the modal
$("html, body").scrollTop($("#modalId").offset().top);
If you want to scroll the modal div to the top use
$("#modalId").scrollTop(0);
Example on jsFiddle
You can combine both to scroll the page and the modal to a visible area for the user if needed.
References
jQuery scrollTop
jQuery offset
This is a solution without using JQuery, first you get your modal by the id and then, the function scrollIntoView will move to the top of the element you selected, in this case your modal.
let element = document.getElementById('groupModal');
element.scrollIntoView(true);
To avoid rough movement to the top I would prefer to use (animated movement):
$('#modalId').animate({
scrollTop : 0
}, 'slow');
<script type="text/javascript">
$(document).ready(function(){
$('.scroll_top').hide();
$(window).scroll(function(){
if ($(this).scrollTop() > 100) {
$('.scroll_top').fadeIn();
} else {
$('.scroll_top').fadeOut();
}
});
$('.scroll_top').click(function(){
$("html, body").animate({ scrollTop: 0 }, 500);
return false;
});
});
</script>
You have to include "jquery-1.7.1.min.js" file in your page.
