modal window pop up leaving the page - javascript

Hey guys I'm using bootstrap modal class for popping up window when a user leaves the page.
And what I need is to pop up the window using javascript not the button.
So it does not work and I'm stuck with it, any help is appreciated
Modal Window
<div class="modal fade" data-toggle="draftModal" data-target="#draftModal">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-body">
<button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button>
<div>
<p>You are about to leave the deal. Would you like to save as a draft?</p>
</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>
</div>
JS
<script type="text/javascript">
$(document).ready(function(){
window.onbeforeunload(function(event){
event.preventDefault();
$('.modal').modal('show');
});
});

You can not override the onbeforeunload dialog with your own, so unfortunately you better be working with it as it's intended. The dialog will show, but also the once coming with the intended event. Reference: http://msdn.microsoft.com/en-us/library/ms536907%28VS.85%29.aspx

How to open bootstrap modal using a button click

I have developed a simple js pig game. You can see it here: http://creativeartbd.com/demo/game/js-pig-game
At first, it will open a Bootstrap Modal box to set a winning score. Now, the game will begin by click on the Roll Dice button.
Well, now if you WIN then you can press the New Game button to re-play the game. Here, I want to open the bootstrap modal again when I click on the New Game button. For that I have write this code:
document.querySelector(".btn-new-game").addEventListener("click", function () {
init();
document.getElementById("myModal").modal('show');
});
but it's showing me an error message on console log:
Uncaught TypeError: document.getElementById(...).modal is not a function
Maybe this is because of Javascript IIFE. I don't know exactly :(
I have also tried with this code:
document.getElementById("myModal").click();
but no luck :(
My HTML and js code is a bit long that's why I don't put here. You can find it here: https://jsfiddle.net/r8cga7L5/
Thanks.
Modify the button like this,
It's working perfectly fine
<button data-toggle="modal" data-target="#myModal" class="btn btn-new-game">New Game(+)</button>
Any specific reason you want the modal to open from JS?
Try this for the Bootstrap 4 approach:
<!-- Button trigger modal -->
<button type="button" class="btn btn-primary" data-toggle="modal" data-target="#exampleModal">
Launch demo modal
</button>
<!-- Modal -->
<div class="modal" 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">Modal title</h5>
<button type="button" class="close" data-dismiss="modal" aria-label="Close">
<span aria-hidden="true">×</span>
</button>
</div>
<div class="modal-body">
...
</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>
You can just call it like this:
document.getElementById("myModal").modal();

bootstrap multiple modal structure

I have a structure as below. Modal1 for displaying my content and Modal2 pops up when a alert modal when deleting.
I have first modal1 loading in Ajax
Second modal is not Ajax call.
Is it advisable to have this structure with multiple modals? Otherwise what is the alternative to get alert message in a modal?
Because right now I am facing weird issues with closing modals and events. It is working some times and some time it doesn't . Not sure what causes the weirdness.
Any leads on do and don'ts will be helpful.

Nested modals are not supported in bootstrap 3 that's why you are getting wired results
From bootstrap docs:
Multiple open modals not supported
Be sure not to open a modal while another is still visible. Showing more than one modal at a time requires custom code.
Instead of using a second modal You can use an alert to show notification msg inside the first modal

How to make modals with different content

I want to make a website (done). Then I´m adding at least 30 buttons, and when you press the first button, a simple modal comes up with the ability to close, but when you press the second button, the same thing happens! It's just another content.
Let me try to tell you this in my bad programming language.
<div class="button" id="modal1">1</div>
if pressed = "modal1" opens.
<div class="button" id="modal2">2</div>
îf pressed = "modal2" opens with different content.
I would add some code, but I haven´t got any longer than the Bootstrap: http://www.w3schools.com/bootstrap/tryit.asp?filename=trybs_modal&stacked=h
just check this link http://www.w3schools.com/bootstrap/bootstrap_modal.asp it explain how modal works. You must have data-toggle="modal" data-target="#myModal" in item you click to open modal and you need mention "#myModal" as id of the target modal, use different id to open different modal.
Using the sample you linked, I copied and pasted the first model div to a second and made minor changes so you can see the difference when clicking on the buttons.
I then copied and pasted the button, and changed the data-target attribute in the second button to match the div I added.
<div class="container">
<h2>Modal Example</h2>
<!-- Trigger the modal with a button -->
<!-- data-target in the first button matches the id of the first div below -->
<button type="button" class="btn btn-info btn-lg" data-toggle="modal" data-target="#myModal">Open Modal</button>
<!-- the second button data-target matches the id of thj e second div below -->
<button type="button" class="btn btn-info btn-lg" data-toggle="modal" data-target="#myModal2">Open Modal</button>
<!-- Modal -->
<div class="modal fade" id="myModal" role="dialog">
<div class="modal-dialog">
<!-- Modal content-->
<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>Some text in the modal.</p>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
</div>
</div>
</div>
</div>
<!-- this is copied from the first div, given its own id -->
<div class="modal fade" id="myModal2" role="dialog">
<div class="modal-dialog">
<!-- Modal content-->
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal">×</button>
<h4 class="modal-title">Modal Header 2</h4>
</div>
<div class="modal-body">
<p>Some text in the modal. model 2</p>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
</div>
</div>
</div>
</div>
</div>
You can see my three modals, like i said you just need to change data-target="#myModal1" and id="myModal1"

If you use Bootstrap modal u need just to change data-target and crate modals for all buttons.

Modal window blocks my page

I have a modal window but when I close the modal my page is blocked. I can not do anything. I need to refresh the page to get everything working again!
The strange is that sometimes everything works well or sometimes everything is blocked!
The button that opens the model:
<button type="button" class="btn btn-success" data-toggle="modal" data-target="#myModalCode">Approve</button>
My modal window code:
<!-- Modal-->
<div class="modal fade" id="myModalCode" role="dialog">
<div class="modal-dialog modal-sm">
<div class="modal-content">
<form id="formUpdateProgress" >
{!! csrf_field() !!}
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal">×</button>
<h4 class="modal-title">Complaint Progress</h4>
</div>
<div class="modal-body">
<label class="control-label">Insert code:</label>
<div id='complaintProgress' style="position: relative;">
<input type="text" name="code" id="code" placeholder="Insert the code here">
</div>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-danger" data-dismiss="modal">Close</button>
<button type="submit" class="btn btn-success">Submit</button>
</div>
</form>
</div>
</div>
</div>
<!-- END MODAL -->
When I submit the form, I close the model!
$( '#formUpdateProgress' ).on( 'submit', function(e) {
$('#myModalCode').modal('hide');
});
EXAMPLE:
Modal window in my application:
Then I click Submit, everything works ok, the document is approved but something is locking the page:
Any idea why the page is blocked? Thanks in advance
Similar issues is discussed in here:
How to hide Bootstrap modal from javascript?
Seems that you have some issues in the way how your modal is handling the submit. Perhaps the easiest fix would be as was mentioned in one of the comments from the link above, add the following fix to remove the backdrop:
$('.modal-backdrop').hide();
Alternatively, you may even remove() it. I'd think, modal will re-create it again, if open.
It's looks like you are using bootstrap modal.
Bootstrap open not only modal, but page mask too. So you need to call bootstrap method to close. With code inspector you can find that body got class="modal-open" and extra div with "modal-backdrop fade in"
Just use <button type="button" class="btn btn-default" data-dismiss="modal">Close</button> or yr element with 'data-dismiss="modal"' and all be ok)
function closeModal(name){
$("#"+name).modal('hide');
// I added the next line
$('.modal-backdrop').hide();
}
After I add the $('.modal-backdrop').hide(); everything its ok :)
