i'm using the modal example from the bootstrap 3 docs. the modal works. however i need to access the show.bs.modal event when it fires. for now i'm just trying:
$('#myModal').on('show.bs.modal', function () {
alert('hi')
})
Nothing happens, the event does not fire. What am I doing wrong??? This doesn't make sense to me.
use this:
$(document).on('show.bs.modal','#myModal', function () {
alert('hi');
})
Make sure you put your on('shown.bs.modal') before instantiating the modal to pop up
$("#myModal").on("shown.bs.modal", function () {
alert('Hi');
});
$("#myModal").modal('show'); //This can also be $("#myModal").modal({ show: true });
or
$("#myModal").on("shown.bs.modal", function () {
alert('Hi');
}).modal('show');
To focus on a field, it is better to use the shown.bs.modal in stead of show.bs.modal but maybe for other reasons you want to hide something the the background or set something right before the modal starts showing, use the show.bs.modal function.
Wrap your function in $(document).ready(function() { }), or more simply, $(function() {. In CoffeeScript, this would look like
$ ->
$('#myModal').on 'show.bs.modal', (event)->
Without it, the JavaScript is executing before the document loads, and #myModal is not part of the DOM yet. Here is the Bootstrap reference.
$(document).on('shown.bs.modal','.modal', function () {
/// TODO EVENTS
});
Try this
$('#myModal').on('shown.bs.modal', function () {
alert('hi');
});
Using shown instead of show also make sure you have your semi colons at the end of your function and alert.
Add this:
$(document).ready(function(){
$(document).on('shown.bs.modal','.modal', function () {
// DO EVENTS
});
});
Similar thing happened to me and I have solved using setTimeout.
Bootstrap is using the following timeout to complete showing:
c.TRANSITION_DURATION=300,c.BACKDROP_TRANSITION_DURATION=150,
So using more than 300 must work and for me 200 is working:
$('#myModal').on('show.bs.modal', function (e) {
setTimeout(function(){
//Do something if necessary
}, 300);
})
In my case, I was missing the .modal-dialog div
Doesn't fire event: shown.bs.modal
<div id="loadingModal" class="modal fade">
<p>Loading...</p>
</div>
Does fire event: shown.bs.modal
<div id="loadingModal" class="modal fade">
<div class="modal-dialog">
<p>Loading...</p>
</div>
</div>
I had the same issue with bootstrap4.
The solution was to add it inside the jQuery document ready() function:
$(document).ready(function() {
$('#myModal').on('show.bs.modal', function () {
alert('hi')
})
}
This happens when code might been executed before and it's not showing up so you can add timeout() for it tp fire.
$(document).on('shown.bs.modal', function (event) {
setTimeout(function(){
alert("Hi");
},1000);
});
I had a similar but different problem and still unable to work when I use $('#myModal'). I was able to get it working when I use $(window).
My other problem is that I found that the show event would not fire if I stored my modal div html content in a javascript variable like.
var content="<div id='myModal' ...";
$(content).modal();
$(window).on('show.bs.modal', function (e) {
alert('show test');
});
the event never fired because it didn't occur
my fix was to include the divs in the html body
<body>
<div id='myModal'>
...
</div>
<script>
$('#myModal).modal();
$(window).on('show.bs.modal', function (e) {
alert('show test');
});
</script>
</body>
Remember to put the script after the call of "js/bootstrap", not before.
Had the same issue. For me it was that i loaded jquery twice in this order:
Loaded jQuery
Loaded Bootstrap
Loaded jQuery again
When jQuery was loaded the second time it somehow broke the references to bootstrap and the modal opened but the on('shown.bs..') method never fired.
Ensure that you are loading jQuery before you use Bootstrap. Sounds basic, but I was having issues catching these modal events and turns out the error was not with my code but that I was loading Bootstrap before jQuery.
Sometimes this doesn't work if:
1) you have an error in the java script code before your line with $('#myModal').on('show.bs.modal'...). To troubleshoot put an alert message before the line to see if it comes up when you load the page. To resolve eliminate JSs above to see which one is the problem
2) Another problem is if you load up the JS in wrong order. For example you can have the $('#myModal').on('show.bs.modal'...) part before you actually load JQuery.js. In that case your call will be ignored, so first in the HTML (view page source to be sure) check if the script link to JQuery is above your modal onShow call, otherwise it will be ignored. To troubleshoot put an alert inside the on show an one before. If you see the one before and not the one inside the onShow function it is clear that the function cannot execute. If the spelling is right more than likely your call to JQuery.js is not made or it is made after the onShow part
Make sure that you really use the bootstrap jquery modal and not another jquery modal.
Wasted way too much time on this...
In my case the problem was how travelsize comment.. The order of imports between bootstrap.js and jquery. Because I'am using the template Metronic and doesn't check before
i used jQuery's event delegation /bubbling... that worked for me. See below:
$(document).on('click', '#btnSubmit', function () {
alert('hi loo');
})
very good info too: https://learn.jquery.com/events/event-delegation/
The popular solution to put a setTimeout could work in some case, but is a terrible solution. I was myself using it amongst wraping it in $(document).ready() off course (but it never helped), but I was never able to have a reliable solution. Some browser/system take more time than other, and sometime 1000ms was not enough. And I was tired searching why the $(document).ready() wasn't helping, so :
I took a different approach.
I make the subscription to modal events when I need to use the modal for the first time.
Open my modal
and on the JS side :
function ShowModal() {
InitModalEventsOnce();
$('#MyModal').modal('show');
}
var InitModalEventsIsDone = false; // Flag to keep track of the subscribtion
function InitModalEventsOnce() {
if (!InitModalEventsIsDone) {
InitModalEventsIsDone = true;
$('#MyModal').on('shown.bs.modal', function () {
// something
})
$('#MyModal').on('hidden.bs.modal', function (e) {
// something
});
}
}
And that's it! The only reliable solution I found.
Try like this.
let mymodal=$('#myModal');
mymodal.on('show.bs.modal', function ()
{
alert('hi')
});
Below are the granular details:
show.bs.modal works while model dialog loading
shown.bs.modal worked to do any thing after loading. post rendering

I have a problem with jquery 1.9.1 . I have searched it but these are not solved my problem.
$('.sm2_expander').live('click', function() {
$(this).parent().parent().toggleClass('sm2_liOpen').toggleClass('sm2_liClosed');
return false;
});
Everybody said that "use 'on' function" but this time my code never work.
$(document).on("click", "a.offsite", function(){ alert("Goodbye!"); });
Edit : Here is my using prject page : draggable link
In your example you have used the selector a.offsite but there are no elements matching this selector in your page. That might be the reason why it is not working.
$(function(){
$(document).on('click', '.sm2_expander', function(){
alert('bye');
$(this).parent().parent().toggleClass('sm2_liOpen').toggleClass('sm2_liClosed');
})
})
I think you can shorten this to
$(function(){
$(document).on('click', '.sm2_expander', function(){
$(this).closest('li').toggleClass('sm2_liOpen sm2_liClosed');
})
})
.live() was introduced in jQuery 1.3, therefore it won't work with earlier versions.
.live() has also since been deprecated in jQuery 1.7 onwards.
The alternatives are .on() and .delegate()
See related question jQuery 1.9 .live() is not a function on how to migrate existing code.
I used "jquery-1.8.3.min.js" and my problem solved.
Try this out :- http://jsfiddle.net/trdb9/
JS:-
$(document).on("click", "a.offsite", function () {
alert("Goodbye!");
});
HTML:-
<a class="offsite">Click Me</a>
You need to use jquery-migrate-1.1.1.min.js or higher. I guess there are big changes coming in jquery, one being making everyone who relied on .live to find new ways.
Anyhow, try that and it should work.
Try replacing live with on in your code.
$('.sm2_expander').on('click', function() {
$(this).parent().parent().toggleClass('sm2_liOpen').toggleClass('sm2_liClosed');
return false;
});
If you have a live site, I will recommend to use jQuery Migrate
https://github.com/jquery/jquery-migrate/
It will automatically add the deprecated but needed functions.
I want to attach a event to dynamically created element class.So i used live function but it was not triggered. So checked live function reference ,there i red below notes
As of jQuery 1.7, the .live() method is deprecated. Use .on() to
attach event handlers. Users of older versions of jQuery should use
.delegate() in preference to .live().
so decide to use on function,But it still not working.The text field is already attached with jquery ui datpicker.On another element select i disabled that field.
jQuery("#from").attr('disabled','disabled')
.removeClass('date_picker_bg')
.removeClass('hasDatepicker')
.addClass('date_picker_disabled');
after disabled if i click i want to show alert or tooltip.so i tried this,but not working
jQuery(".date_picker_disabled").on("click", function(event){
alert('hi');
});
What may be the problem
I am using jquery 1.7.1 ( jquery-1.7.1.min.js)
The problem is that jQuery(".date_picker_disabled") finds elements with that class and binds to them. If elements don't have the class at the time the binding is made, the events will not be handled.
The on function allows you to get round this by handling them on another element when the event "bubbles up to" a parent element. In this instance, we could say the body element – there may be a more specific common parent you could choose.
jQuery(document.body).on('click', '.date_picker_disabled', function(event) {
alert('hi');
});
The event handler is now bound to the document.body element. All clicks that happen anywhere in the body are tested to see if they originated from an element matching the selector. If so, the handler is fired.
This is explained on the documentation for the on function. It is the same behaviour as was present in previous versions of jQuery with live and delegate functions.
Having taken another look at your code, you have disabled="disabled" set on your input element. click events are not fired on disabled elements.
This is tricky.
When your code runs, your element does not have .date_picker_disabled class so your jQuery(".date_picker_disabled") returns nothing and .on() is not called.
Apply .on() on the outer element and use the selector parameter:
// you can also do $(document).on()
$(<outer element>).on('click', '.date_picker_disabled', function() {
// do something
});
This will delegate the event to the <outer element>. The handler will only be executed if an element with class .date_picker_disabled has been clicked (second param).
From the documentation of .live():
Rewriting the .live() method in terms of its successors is
straightforward; these are templates for equivalent calls for all
three event attachment methods:
$(selector).live(events, data, handler); // jQuery 1.3+
$(document).delegate(selector, events, data, handler); // jQuery 1.4.3+
$(document).on(events, selector, data, handler); // jQuery 1.7+
So in your case, you would do:
$(document).on('click', '.date_picker_disabled', function(event){
alert('hi');
});
I was using jQuery 1.7.2 and tried all proposed methods:
Didn't work:
$(document.body).on('click', '.collapsible-toggle' function() {
console.log('clicked');
});
Didn't work:
$(document).on('click', '.collapsible-toggle' function() {
console.log('clicked');
});
None of them worked until I tried the following:
----- Worked! ----
$('body .collapsible-toggle').on('click', function() {
console.log('clicked');
});
Maybe you should do:
jQuery("body").on("click",".date_picker_disabled", function(event){
alert('hi');
});
in this way you attach the event handler to the bosy and specify to fire that event only when that selector ".date_picker_disabled" is matched.
BTW this is exactly how live() worked
try :
$(document.body).on( "click", ".date_picker_disabled", function() {
alert('hi');
});
document.body helps for dynamic html too.
Just chekc it out: .on not working on dynamic html
I have a page that lists content that are contained in a div with a class ad-container. in that container there is a hidden div with the class ad-contact. on the hover of the ad class i want to animate the display of ad-info. since there are multiple ads on a paticular page, i want only the ad-info of the currently hovered ad-container to slide in. my problem is that since there are more than 10 ads a page when you hover over any of the ads, all of the ads-contact divs slideDown and not the one you are hovering over.
$(document).ready(function() {
$('.ad-container').hover(
function(){
$(".ad-contact").slideDown(1000);
},
function(){
$(".ad-contact").slideUp(1000);
});
});
i think, (this) is used here but im not sure. and this would really shed the light for me.
<div class="ad-container">
<div class="ad-title">title<span class="ad-title-img">(pic)</span></div>
<div class="ad-description">texttext</div>
<div class="ad-contact" style="display:none">contact poster</div>
<div class="ad-sellerinfo" style="display:none">* Verified ***-****<br />
Paid Member</div>
</div>
The jQuery constructor accepts a 2nd parameter which can be used to override the context of the selection. Something like this should work:
$(document).ready(function() {
$('.ad-container').hover(
function(){
$(".ad-contact", this).slideDown(1000);
},
function(){
$(".ad-contact", this).slideUp(1000);
});
});
Also, worth mentioning, $(".ad-contact", this) is internally converted into: $(this).find(".ad-contact") so you can use this one instead, it might be slightly faster.
You could use the .children() selector:
$(this).children(".ad-contact").slideDown(1000);
This way you will only act on the class ad-contact if its a child of the object in context (which is the object currently being hovered)
See a working demo here
You should use event to handle this,
First you need like
ad-container.hover(function(event){
event.target.children();
})
and then this.show().delay(1000).hide();
the code sample provide may not work when copy paste you have to write your own code in editor.
This is a rephrased question from here. After some testing I isolated the problem, but have no clue on fixing it. No need to read the previous question, this is the simplified code:
THE PROBLEM -> trigger('click') executes, but the event doesn't trigger when inside looped (intervaled) function
$(document.ready(function(){
var checkForConfirmation = function(){
clearInterval(checkInterval);
$("#anchorLink").trigger('click');
}
var checkInterval = setInterval(function(){checkForConfirmation()}, 5000);
});
The function is being called in intervals. When the proper response is replied, interval stops, and simulates the click on an anchor link.
In the html file there is an anchor link <a id="anchorLink" href="#hiddenDiv">Show</a>.
It points to the hidden div which has some content. I'm using Fancybox plugin to show the hidden div when the anchor link is clicked.
If I click on Show link fancybox shows, as expected.
If I get the response from the back-end, code executes as expected, but fancybox is not shown.
If I move $("#anchorLink").trigger('click'); outside the checkForConfirmation function, fancybox shows.
When I replace $("#anchorLink").trigger('click'); with $("#anchorLink").text('Im clicked'); the string shows in the <a id="ancoredLink"> tag.
This is the summary, I have tried it in different situations.
The problem is obviously in triggering the click event while in looping function. The $("#anchorLink") selector is accessible, it is triggering it correctly from everywhere else. Obviously there is a problem in triggering the mouse event inside looping function.
Any suggestions?
Try:
$(document).ready(function(){
// ...
});
instead of:
$(document.ready(function(){
// ...
});
When I get new elements from load() function can't find the way to attach the function .fancybox (a lightbox plugin) to elements.
I've tried with .live() and .delegate(), but think .fancybox() could not be considered as custom event. I probably miss something... :(
You must wait until the DOM has been updated after the load. Add a one-shot timer in the success function called by load(). That should do the trick.
You need to trigger your fancybox after your content has loaded. Use a callback function.
$('#result').load('your/content.html', function() {
// after load trigger your fancybox
alert('Load was performed.');
});
