I'm working on jeopardy game where I pass questions into a bootstrap modal based on the button clicked. The button has an attribute data-num, (the index in the array of questions), which is used to to change the title in the modal. It also passes this index as an attribute data-num to the reveal answer button, which, when clicked, will change modal title to the answer.
This works for the first question, but when I click on the second question, the proper question loads, but the answer to the first question loads when I click the getanswer button, even though the proper index shows up in inspect element under button data-num.
What am I doing wrong?
var questions = [{
prompt: "What generic data type should we use when we want to use varying data types for a variable?",
correctAnswer: "Object",
},
{
prompt: "Rewrite the following Javascript statment in C#: var flag = true ",
correctAnswer: "bool flag = true"
},
{
prompt: "double num1 = 9.34534910;\n int num2= (int)num1;\nSystem.Console.WriteLine(num2);",
correctAnswer: "9"
}
];
function showQuestion(event, $modal) {
var button = $(event.relatedTarget);
var num = parseInt(button.data('num'));
var question = questions[num];
$modal.find('.modal-title').text(question.prompt);
$modal.find('.modal-body button').attr('data-num', num)
}
$("#myModal").on('show.bs.modal', function(event) {
showQuestion(event, $(this));
}
);
$("#myModal").on('hidden.bs.modal', function() {
$('#myModal').removeData('bs.modal');
}
);
$("#getanswer").click(function() {
var num = ($(this).data('num'));
console.log(num)
}
)

Use this (on the #getAnswer click event):
var num = ($(this).attr('data-num'));
instead of
var num = ($(this).data('num'));
Perhaps since you set the value with attr, it also works to retrieve it that way.
It DOES seem like your way should work, but this is what I found through trying stuff.

I'm kind of stuck at the moment. Would really appreciate if someone can help me with this.
First time asking a question, so please bear with me :)
I have a main page with a few buttons. Each button opens a bootstrap modal. I am able to load dynamic content into the modal. Also inserting external HTML works, but here's the catch.... The HTML content I insert also has some 'fancy' features like my main page has (ex. animated progress bar/skills) For the external HTML to work I need to reference the same script as my main page has, but if so, things on my main page gets broken.
My question is, is there any way that I can insert HTML into my modal and have the inserted HTML be able to use the existing functions on my main page?
var iModal = document.getElementById('iModal');
iModal.addEventListener('show.bs.modal', function handler() {
// Button that triggered the modal
var button = event.relatedTarget;
var modalTitleArg = button.getAttribute('data-bs-title');
var modalId = button.getAttribute('data-bs-id');
var modalTitle = iModal.querySelector('.modal-title');
var modalBody = iModal.querySelector('.modal-body');
modalTitle.textContent = modalTitleArg;
if (modalId == 1) {
$('.modal-body').load('Content1.html', function() {
$.getScript("js/functions.js") //get script, modal works, broken mainpage.
});
} else if (modalId == 2) {
$('.modal-body').load('Content2.html', function() {
//$.getScript("js/functions.js") //script reference in html, modal works broken mainpage
});
} else {
$('.modal-body').load('Content3.html', function() {
//$.getScript("js/functions.js") // no script at all, broken modal, mainpage works fine
});
}
this.removeEventListener('show.bs.modal', handler);
});

<script src="js/functions.js"></script>
If in your "Content1.html", "Content2.html" etc. there is already an attached <script src="js/functions.js"></script> (as in a simple web page), then you can add content simply through an iframe tag (via the src attribute). Sample part of the code from your example:
...
<div class="modal-body">
<iframe class="modal-body-frame"></iframe>
</div>
...
<script>
...
const modalFrame = document.querySelector('.modal-body-frame');
if (modalId === 1) modalFrame.src = 'Content1.html';
...
</script>
...
But if you need to embed the script into the content every time, then you can use the srcdoc attribute of the iframe tag. Example below:
...
<div class="modal-body">
<iframe class="modal-body-frame" srcdoc=""></iframe>
</div>
...
<script>
...
const modalFrame = document.querySelector('.modal-body-frame');
if (modalId === 1) {
$.get('Content1.html', function(data) {
modalFrame.srcdoc = data.replace('</head>', '<script src="js/functions.js"></script></head>');
})
}
...
</script>
...
When using frame, it is important not to forget about Feature Policy and the ability to add permission via the allow attribute (Example: <iframe srcdoc="<p>Example test page</p>" allow="fullscreen"></iframe>).
I have a modal with two buttons. One is a yes button and one is a no button. If yes button is pressed, I would like the remainder of the function to execute. If no btn clicked, I would like the page to prevent default and not execute. However, it seems that regardless of which button is clicked, nothing happens besides the modal closing. I am using a modal example I found elsewhere, so this may be the issue. After glancing at it for some time I cannot seem to find where the issue is. Am I missing something small? Or perhaps my Jquery is wrong? Below is my code:
Modal:
<!-- Modal for delete-->
<div class="modal fade" id="deleteModal" tabindex="-1" role="dialog" aria-hidden="true">
<div class="modal-dialog" role="document">
<div class="modal-content border-primary mb-3 box-shadow-none img-responsive">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" aria-label="Close">
<span aria-hidden="true">×</span>
</button>
</div>
<div class="card-body bg-light">
<div id="del" class="center">
<label>Are you sure you want to delete?</label>
</div>
</div>
<div class="modal-footer">
<div id="deleteYes">
<button type="button" class="btn btn-default" data-dismiss="modal" id="deleteYes">Yes</button>
</div>
<div id="deleteNo">
<button type="button" class="btn btn-default" data-dismiss="modal" id="deleteNo">No</button>
</div>
</div>
</div>
</div>
</div>
And here is my Jquery:
$(".btnDeleteTerminalCommand").click(function (e) {
$("#deleteModal").modal('toggle');
if ($("#deleteNo").click) {
return e.preventDefault();
}
var rowId = "#" + $(this).data("rowindex");
var row = $(rowId);
var termId = row.find(".tdTermId").html().trim();
var cmdId = row.find(".tdCmdId").html().trim();
var cmdVal = row.find(".tdCmdVal").html().trim();
var cmdID = row.find(".cmdID").html().trim();
var data = {
TerminalID: termId,
CommandID: cmdId,
CommandValue: cmdVal,
ID: cmdID
};
$.ajax({
url: '#Url.Action("DeleteTerminalCommand", "TerminalCommand")',
type: "POST",
data: data,
success: function (response) {
console.log("Success");
window.location.href = response.Url;
}
});
});
Any advice helps! Thank you!
Your click handler will toggle the modal and immediately continue to execute the rest of the function before the user can click anything. If your modal has two buttons, create a click handler for each button. Perhaps the No button just closes the modal. The Yes button handler can execute the actions required to accomplish the task.
$(".btnDeleteTerminalCommand").click(function(e){
$("#deleteModal").modal('toggle');
}
$("#deleteNo").click(function(e){
$("#deleteModal").modal('hide');
}
$("#deleteYes").click(function(e){
// build data object
// ajax post
}
I have read the Bootsrap documentation and even tested their "Varying modal content based on trigger button" example, but that doesn't work.
Any idea on how can I pass a data to a modal so that I will not create multiple modals in my page.
Here is the button that triggers the modal:
<a class="btn btn-danger" data-toggle="modal" data-target="#deleteSubject" data-whatever="<?= $subj_id ?>" role="button" title="Delete Subject"><span class="glyphicon glyphicon-trash" aria-hidden="true"></span></a>
And here is the modal:
<div class="modal fade" id="deleteSubject" tabindex="-1" role="dialog" aria-labelledby="deleteSubjectLabel">
<div class="modal-dialog" role="document">
<div class="modal-content">
<form action="#" method="post">
<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="deleteSubjectLabel">Delete Subject</h4>
</div>
<div class="modal-body">
<h4>Do you want to delete this subject?</h4>
<input type="text" id="subjid" name="subjid">
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Cancel</button>
<button type="submit" class="btn btn-danger">Delete</button>
</div>
</form>
</div>
</div>
</div>
And here is the javascript:
<script>
$('#deleteSubject').on('show.bs.modal', function (event) {
var button = $(event.relatedTarget)
var subjId = button.data('whatever')
var modal = $(this)
modal.find('.modal-body input').val(subjId)
})
</script>
I also tried the show.bs.modal but nothing happens. I tried to create a separate script to test if the $subj_id is being read through the use of alert but it works.
Any ideas?
you need to wrap the code in a document ready and since your input is named and has an id - target it directly and then you wont need the find either:
<script>
$(document).ready(function(){
$('#deleteSubject').on('show.bs.modal', function (event) {
var button = $(event.relatedTarget);
var subjId = button.data('whatever');
$('#subjid').val(subjId);
})
})
</script>
I think you forgot the $ on your modal instance , it should be $modal
<script>
$('#deleteSubject').on('show.bs.modal', function (event) {
var button = $(event.relatedTarget)
var subjId = button.data('whatever')
var $modal = $(this)
$modal.find('.modal-body input').val(subjId)
})
</script>
Simply set the value of input subjid using JavaScript / jQuery during the on click event.
$('#subjid').val(*value*);
Here is my code:
<div class="superBlock" id="blabla">
<a class="watch"><img src="images/blabla.png"/></a>
</br>
<div class="btn-group-xs" role="group">
<a type="button" class="btn btn-info info" data-toggle="modal" data-target="#myModal">Information</a>
</div>
</div>
<div class="modal fade" id="myModal" role="dialog">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-footer">
<a type="button" class="btn btn-success watch" data-dismiss="modal">Watch</a>
</div>
</div>
</div>
</div>
$('.info').click(function() {
var $watchID = $(this).parents('.superBlock').attr('id');
});
$('.watch').click(function() {
if($(this).parents('.superBlock').attr('id') != "") {
var $watchID = $(this).parents('.superBlock').attr('id');
}
alert($watchID);
});
What I'd like to do is to set the $watchID to the .superBlock's ID whether I click on the .watch button or on the .info button.
And I get $watchID is "undefined" when I click on the modal watch button after clicking on the info button.
And I'd like the $watchID to keep on being set to the .superBlock's ID if the $(this).parents('.superBlock').attr('id') is undefined. So the $watchID not to change to the undefined $(this).parents('.superBlock').attr('id').
What should I do? Is this only about syntax? If so, how should I change this?
This HTML divs are repeating with different IDs, that's why I can't just set the ID to "blabla".
To tell if a selector matches anything, check the length of the jQuery object.
var superblock = $(this).closest(".superBlock");
if (superblock.length > 0) {
$watchID = superblock.attr('id');
}
Also, if you want the $watchID variable to persist between calls, it should be declared outside the functions. Your variable is local to each function, so it gets discarded when the function returns.
And since you just want the closest parent with that class, use .closest() rather than .parents(), which searches the entire DOM hierarchy for multiple matches.
I am trying to figure out why this particular Bootstrap confirmation modal is not working with my desired function. It does appear to work with a basic function bringing up an alert window but when I put the function I want it, it executes the function (in this case deletes an image from File-stack and my db) but it hangs up the modal window to where the modal window closes but there is that grey overlay stuck and it makes the page no longer functional. The function that seems to be holding this up is in the first button in the modal-footerdiv towards the bottom. The close button works fine and again it works fine when I put a simple function in place of the removeMoreImage() function Here is the code for the Bootstrap modal:
<button type="button" class="btn btn-danger" data-toggle="modal" data-target="#confirm-modal-more"> <span class= "glyphicon glyphicon-remove-circle"></span> REMOVE IMAGE</button>
<div id="confirm-modal-more" class="modal fade" role="dialog">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal">×</button>
<h4 class="modal-title">Remove Image Confirmation</h4>
</div>
<div class="modal-body">
<p>Are you sure you want to delete this image?</p>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-danger" data-ng-click="removeMoreImage(picture.url, car)" data-dismiss="modal" >REMOVE</button>
<button type="button" class="btn btn-default" data-dismiss="modal">CANCEL</button>
</div>
</div>
</div>
</div>
Here is the function that is is executing causing the hangup:
var getIndexIfObjWithOwnAttr = function(array, attr, value) {
for (var i = 0; i < array.length; i++) {
if (array[i].hasOwnProperty(attr) && array[i][attr] === value) {
return i;
}
}
return -1;
}
$scope.removeMoreImage = function(image, data) {
var index = getIndexIfObjWithOwnAttr(data.morePictures, 'url', image);
data.morePictures.splice(index, 1);
filepickerService.remove(image);
console.log(image + " has been removed!");
}
Any insights or advice would be great. It seems like sync issue but I am not sure.
I ended up using some query to force the modal close and it seems to work nicely though it is not as elegant of a solution as I was hoping for but it seems to work. This is the code I added to the function that was hanging up the modal.
$('#confirm-modal-more').modal('hide');
$('body').removeClass('modal-open');
$('.modal-backdrop').remove();
You can close the modal in the function and return a result to the parent controller:
$uibModalInstance.close('some result of modal');
$uibModalInstance.dismiss('some reason for discarding and closing');
$scope.removeMoreImage = function(image, data) {
var index = getIndexIfObjWithOwnAttr(data.morePictures, 'url', image);
data.morePictures.splice(index, 1);
filepickerService.remove(image);
console.log(image + " has been removed!");
// close modal
$uibModalInstance.close();
}
