Hello this is what i want to do. I want to show the alert box after the user click the link. My link is directed to another php page but it will come back again to the page where the link is found. How can i achieve this? Can someone give me ideas on how to do it?
this is what i tried but not working.
<?php
function fsa() {
echo '<div class="alert alert-success alert-dismissable" id="success-alert">';
echo '<strong>Successfully posted!</strong>';
echo '</div>';
}
<a class='btn btn-info left-margin' href="dbf-import.php" onclick="fsa()">Import Database</a>
This is an example to show the dissmissable alert box when clicking on a button.
$(document).ready(function() {
$('.activater').click(function() {
$('.alert').show()
})
});
.alert {
display: none;
}

Success! message sent successfully.

You can achieve it through Bootstrap modal instead of alert box. You can design it as according to your need.

PHP is used to generate the HTML and JS. You can have both in a PHP file but you need to see the difference between PHP and JS. The function you've called fsa() is a JS function because it will run client side (on the client machine and after page has been loaded). The onclick param in the HTML tag needs to have a JS function hooked. This way when you click on your <a> tag, fsa() will be fired and the box will show up on the page.
// this is JS, you need <script> tags !!!
<script>
function fsa() {
// define a new variable
var box = '';
// add the HTML inside the JS variable
box += '<div class="alert alert-success alert-dismissable" id="success-alert">';
box += '<strong>Successfully posted!</strong>';
box += '</div>';
// append the HTML contained inside box to the body
document.querySelector('body').innerHTML += box;
}
</script>
<a class='btn btn-info left-margin' onclick="fsa()">Import Database</a>
If you wish to save the data without reloading the client's page, you may want to use AJAX
First of all, like #Iceman said: You are trying to run a javascript function in php, so start by deleting all that. If you just want the user to get an alertbox when clicking on a link, you can simply add
<script> function fsa(){
alert("Your alert message");
}
</script>
Also, if you don't want the person to leave the side, just put href='#', that should take care of it.
Try this
<script type="text/javascript">
function Alert() {
var answer = confirm ("Successfully posted!Please click on OK to continue.")
if (answer)
window.location="http://www.yoursite.com";
}
</script>

The modal shows up just fine when clicking it to open, and the close buttons register that my mouse is hovering over them, but when clicked nothing happens and the modal remains open.
Has anyone encountered/fixed this problem before? All I've seen on here is to add "data-bs-dismiss" but that hasn't made a difference in the modal. I'm new to bootstrap so any and all help would be much appreciated! Code is below, link to full code here -

There are a couple of issues.
Let's start with the way the orange poke-buttons are created.
function addListItem(pokemon) {
let listItem = $('<li class="list-group-item"></li>');
let button = $('<button class="pokemon-button btn btn-warning" data target="#modal-container" data-toggle="modal">' + pokemon.name + '</button>');
listItem.append(button);
pokemonListElement.append(listItem);
button.on('click', function(){
showDetails(pokemon);
});
}
This seems to be fine... But:
let button = $('<button class="pokemon-button btn btn-warning" data target="#modal-container" data-toggle="modal">' + pokemon.name + '</button>');
Take a look at data target="#modal-container . There's a hyphen missing, and instead of this
data target="#modal-container"
it should look like this:
data-target="#modal-container"
Next, there's no need to have this line in your showDetailsModal(pokemon) function:
modalContainer.classList.add('show');
The data-target and data-toggle will cover that part for you.
Finally, your CSS seems to be putting the modal's backdrop on top of the modal. Change this:
#modal-container {
...
z-index: 999;
...
}
to something else (for example, 1051, or you can delete it, and let Bootstrap handle it for you), since the backdrop has a z-index of 1040.
I was able to fix the behavior in the JSFiddle by replacing the following two lines in the showDetailsModal function:
let modalContainer = document.querySelector('#modal-container');
modalContainer.classList.add('is-visible');
with this line:
$('#modal-container').modal('show');
that is one of the methods provided in Bootstrap 4.3 per:
the Bootstrap Modal documentation
Also, it's necessary to add the data-backdrop="false" attribute to your modal-container div in order to maintain the current style/behavior.
This may not be the best solution - I am not sure why your code doesn't work, it seems reasonable to me, but I think it's a good idea to use the default methods provided by the library as other methods (like the close function) may be expecting them and fail to work if you're using an improvised method.
I try to load an external block of html through .load() jquery function, but it fails to render properly in a modal popup (note: same issue with .get() )
code is :
$('#butt2').on('click', function() {
$('#mbodyko').load('nav.html', function() {
$('#myModalnok').modal({show: true });
});
});
Render is bad, here is the issue:
http://plnkr.co/edit/z9oQPVG2F9oYaJCzovN5?p=preview
You can notice that the tabs inside the second modal are not clickable, whereas the same html code renders well in the first modal.
Do you know why ?
Thanks for your hints!
All I did to make it work is removing out the first modal html, like this:
<html dir="ltr" lang="en-US">
<head>
<link rel="stylesheet"
href="//maxcdn.bootstrapcdn.com/bootstrap/3.2.0/css/bootstrap.min.css" />
</head>
<body>
<hr>
<button class="btn btn-primary btn-lg" id="butt1">modal OK</button>
<br />
<br />
<button class="btn btn-primary btn-lg" id="butt2">modal NOK - use jquery .load</button>
<div class="modal fade" id="myModalnok" tabindex="-1" role="dialog" aria-hidden="true">
<div class="modal-dialog">
<div class="modal-body">
<div class="modal-content">
<div class="modal-header">
<h4 class="modal-title" id="myModalLabel">Problem: click does not change the tabs!</h4>
</div>
<div class="modal-body" id="mbodyko">
</div>
</div>
</div>
</div>
</div>
<script src="//ajax.googleapis.com/ajax/libs/jquery/2.2.4/jquery.min.js"></script>
<script src="//maxcdn.bootstrapcdn.com/bootstrap/3.2.0/js/bootstrap.min.js"> </script>
<script>
$('#butt1').on('click', function() {
$('#myModalok').modal({
show: true
});
});
$('#butt2').on('click', function() {
$('#mbodyko').load('nav.html', function() {
$('#myModalnok').modal({
show: true
});
});
});
</script>
</body>
</html>
I think the problem is that the loaded data from nav.html have IDs that are in the original html DOM, or index.html and you can't have a page with two elements that have the same ID, or it will not work properly.
I need to call a function in the main page from the child page. Below i have 2 pages. 1. main.aspx and child page is 2.active.aspx. In active.aspx i have a button called "exit' . when i click on the exit button , i need to close the modal popup and then i need to call function "main" which is a javascript function in the main page. Problem is i am not able to invoke the function from the child page.
Main.aspx
<html>
<head>
<script type="text/javascript">
function main() {
//do main work
}
</script>
</head>
<body>
<div>
<input type="button" class="ic-grid-encode center-btn" title="Interactive"
data-toggle="modal" data-target="#divInterActiveContent" />
</div>
<div class="modal fade" id="divInterActiveContent" tabindex="-1" role="dialog">
<div class="modal-dialog" role="document" align-self="" center;"="">
<iframe id="interId" src="active.aspx"></iframe>
</div>
</div>
</body>
</html>
Active.aspx
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta content="text/html; charset=UTF-8" http-equiv="Content-Type">
<link href="../Content/bootstrap.css" rel="stylesheet">

<script type="text/javascript">
self.btnExit = function () {
parent.$('#divInterActiveContent').modal('hide');
//after closing the popup i need to call the javascript function defined in the main page
//i.e i need call function main which is there in the main window.
}
</script>
</head>
<body>
<form id="frmInterActiveEncode">
<div class="container">
<div class="row" style="margin-top: 10px;">
</div>
<hr>
<br>
<hr>
<div class="row">
<input type="button" value="Submit" class="btn btn-primary" data-bind="event: { click: btnSubmit }">
<input type="button" value="Exit" class="btn btn-primary" data-bind="event: { click: btnExit }">
</div>
</div>
</form>
</body>
</html>
In your scenario, you are actually closing the modal first i.e you are closing the iframe also so you are not able to get parent object in child page after closing the modal.
You should do like
active.aspx
self.btnExit = function () {
parent.main();
}
main.aspx
function main(){
$('#divInterActiveContent').modal('hide');
// Do your stuff
}
This way you can call the parent function and instead of hiding the modal in child hide it in parent function and your next stuff you want to do.
I'm working on a solution that displays a list of thumbnails that are medical images. We have a requirement that states if a user clicks a thumbnail a Bootstrap modal should open that display the image (jpg, png or dicom) using the cornerstone.js library.
Using cornerstone seems pretty straightforward. I setup a quick plunker here.
Here's the code for the working plunk:
<!DOCTYPE html>
<html>
<head>
<link href="//netdna.bootstrapcdn.com/bootstrap/3.1.1/css/bootstrap.min.css" rel="stylesheet">
<script src="jquery.min.js"></script>
<script src="cornerstone.js"></script>
<script src="exampleImageIdLoader.js"></script>
<script type="text/javascript">
$(document).ready(function() {
var imageId = 'example://1';
var element = document.getElementById('dicomImage');
cornerstone.enable(element);
cornerstone.loadImage(imageId).then(function(image) {
cornerstone.displayImage(element, image);
});
});
</script>
</head>
<body>
<div class="container">
<h1>This works just fine...</h1>
<br>
<div id="dicomImage" style="width:512px;height:512px;">
</div>
</div>
</body>
</html>
I can't seem to figure out why the images are not loading when I use the same code in a Bootstrap modal. The plunk that I'm trying to get working is here.
Here's the code for the broken plunk:
<!DOCTYPE html>
<html>
<head>
<link rel="stylesheet" type="text/css" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css">
<script src="jquery.min.js"></script>
<script src="cornerstone.js"></script>
<script src="exampleImageIdLoader.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/js/bootstrap.min.js"></script>
<script type="text/javascript">
$(document).ready(function() {
var imageId = 'example://1';
var element = document.getElementById('dicomImage');
cornerstone.enable(element);
cornerstone.loadImage(imageId).then(function(image) {
cornerstone.displayImage(element, image);
});
});
</script>
</head>
<body>
<div class="container">
<h1>When this modal is opened the canvas looks like it's drawn at 0px x 0px...</h1>
<br />
<button type="button" class="btn btn-info btn-lg" data-toggle="modal" data-target="#myModal">Open Modal</button>
<div id="myModal" class="modal fade" 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">
<div id="dicomImage" style="width:512px;height:512px;"></div>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
</div>
</div>
</div>
</div>
</div>
</body>
</html>
After hours or trying to figure it out I figured I would see if anyone out there has any ideas. It looks like the plunk with the modal is drawing the canvas at 0x0 pixels...
Any thoughts or help would be GREATLY appreciated. Thanks all.
Update 6/26
I may have found a potential workaround, but it's not as clean as I would like it to be. I also haven't tested it by playing a series of CT images.
My thoughts are to use the working solution from the first plunk and to call .hide() on #dicomImage on document.ready. Then, when a user clicks a thumbnail, I will use:
$(".modal-body").appendTO("#dicomImage);
Not the cleanest solution, but it could work...
I'm working on a page with two Bootstrap 3 modals in Chrome. Everything appears fine until you leave the developer console open and launch one of the modals. You can repeat the issue with this jsfiddle, again with the latest Chrome, or create an html page with the below code.

}

<body>
<a href='#reportModal' onclick='launchReportModal()' class='report_link' data-toggle='modal' data-target='#reportModal'>report</a>

<div class="modal-body"></div>
<div class="modal-footer"></div>
</div>
</div>
</div>
</body>
</html>
Edit: Using jQuery selectors to launch the modal in the html fixes the issue, but you can still see the problem in jsfiddle regardless.
$('#launchReportModal').on('click', function(){
$('#reportModal').modal();
});
$('#launchShareModal').on('click', function(){
$('#shareModal').modal();
});
<a href='#' id='launchReportModal' data-toggle='modal' data-target='#reportModal'>report</a>
<a href='#' id='launchShareModal' data-toggle='modal' data-target='#shareModal'>share</a>
You are trying to activate the modals automatically and activate them manually at the same time! If you read the docs :
Activate a modal without writing JavaScript. Set data-toggle="modal"
on a controller element, like a button, along with a
data-target="#foo" or href="#foo" to target a specific modal to
toggle.
You have both
<a href='#' id='launchReportModal' data-toggle='modal' data-target='#reportModal'>report</a>
and
$('#launchReportModal').on('click', function(){
$('#reportModal').modal();
});
The error is triggered like this :
$.fn.modal (_relatedTarget)
Modal.toggle (_relatedTarget)
Modal.hide (_relatedTarget)
_relatedTarget is considered as an event in the code :
Modal.prototype.hide = function (e) {
if (e) e.preventDefault()
-> Uncaught TypeError: Object http://fiddle.jshell.net/22ENG/2/show/# has no method 'preventDefault'
But _relatedTarget is not an event, it is an element. Appearently data-target has higher rank than your $(element).modal() code.
Solution : Just skip your javascript activation of the modals -> http://jsfiddle.net/QFyv9/ - forked jsFiddle using a unminified version of 3.1.1 bootstrap.js (so I could track down the problem)
I have updated the jsfiddle demo:
http://jsfiddle.net/22ENG/11/
<link href="http://netdna.bootstrapcdn.com/bootstrap/3.2.0/css/bootstrap.min.css" rel="stylesheet">
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js"></script>
<script src="http://netdna.bootstrapcdn.com/bootstrap/3.2.0/js/bootstrap.min.js"></script>
and upgraded bootstrap from 3.1.1 to 3.2.0.
The error is gone, and it toggles twice, as coded.
