Popover click event does not work - javascript

$('.pop').each(function () {
var $elem = $(this);
$elem.popover({
placement: 'auto',
trigger: 'hover',
html: true,
container: $elem,
animation: true,
content: function () {
var pop_dest = $(this).attr("data-pop");
//console.log(plant);
return $("#"+pop_dest).html();
}
});
});
$('#english').click(function() { // ---> THIS PART DOES NOT WORK
alert("english");
});
$('#turkce').click(function() { // ---> THIS PART DOES NOT WORK
console.log("turkce");
});
I have 2 button in popover. But their click event does not work. How can I fire click event from button click ? My html code is below.
<li>
<a href="javascript: void(0);" id="languages" class="pop" data-html="true" data-toggle="popover" data-pop="popper-content" class="popper">
<?=$language["languages"]?>
</a>
<div class="hide" id="popper-content">
<ul class="lang-list">
<li class="en">
<button id="english">English</button>
</li>
<li class="tr">
<button id="turkce">Türkçe</button>
</li>
</ul>
</div>
</li>

When you call the click function, the buttons are not added to to page yet (since they are in a dynamically added popover) so you have to use something that takes care of future added content:
$('body').on('click', '#english', function () {
alert("english");
});

You should delegate the event to make sure the event get's to the desired DOM element if it's not present at the time the js gets executed:
$("body").on('click', '#english', function() {
alert("english");
});
$("body").on('click', '#turkce', function() {
alert("turkce");
});
You can delegate events with jquery by using the on method, where the selector is the parent node that will delegate the event to the children, the firs parameter is the event name click, the second is the child you want the event to be delegated to #english and the third parameter is the handler.

The content of the popover is dynamically appended to the page. This means that when you attempt to attach the event handlers when the page loads neither of the buttons exist in the DOM. To fix the problem use a delegated event handler:
$(document).on('click', '#english', function() {
alert("english");
}).on('click', '#turkce', function() {
console.log("turkce");
});

The problem is that <button> has a default type of submit. You don't want that default behavior since you provided your own click handler. You need buttons of type="button".
<button id="english" type="button">English</button>

delegate event on jquery for popover bootstrap not working correctly

i am quite new with this delegate thing for dynamic elements. so today i tested again with a generated dynamic template from some example in stackover for popover.
here is my dynamic html content.
<a id="testpop" class="btn btn-primary" data-placement="top" data-popover-content="#a1" data-toggle="popover" data-trigger="focus" href="#" tabindex="0">Popover Example</a>
<!-- Content for Popover #1 -->
<div class="hidden" id="a1">
<div class="popover-heading">
This is the heading for #1
</div>
<div class="popover-body">
This is the body for #1
</div>
</div>
and then, i have this script on my js
$('#resultContent').on('click','#testpop', function(e) { //use on if jQuery 1.7+
// Enables popover #2
$("[data-toggle=popover]").popover({
html : true,
content: function() {
var content = $(this).attr("data-popover-content");
return $(content).children(".popover-body").html();
},
title: function() {
var title = $(this).attr("data-popover-content");
return $(title).children(".popover-heading").html();
}
});
});
resultContent is the div here where i add .html all my html codes.
i manage to attached the delegate event (i think) but is acting strange as my 1st click on the testpop button, the popover won't show. Until i press the 2nd and 3rd time only it will pop up. Am i doing this delegating wrong?
credits for this test code: HTML inside Twitter Bootstrap popover
You forgot to add a trigger in the popover options. The data-trigger in the element doesn't do too much when you really only initialize the popover() once you click the element. In fact, your JS code would propably work better like so:
$("[data-toggle=popover]").popover({
html : true,
trigger: 'click',
content: function() {
var content = $(this).attr("data-popover-content");
return $(content).children(".popover-body").html();
},
title: function() {
var title = $(this).attr("data-popover-content");
return $(title).children(".popover-heading").html();
}
});
EDIT
Popover should generally be initialized on page load:
$("[data-toggle=popover]").popover();
Putting it inside a click event will not enable popover on the element until you click it first.
Removing the click event from your original JS code should enable it on page load.
If however, the element you mean to attach the popover to is dynamically added to the DOM after page load, you should reinitalize the popover after adding it.
Wrapping the popover in a function would make that much easier.
function addPopover(selector){
$(selector).popover({
html : true,
trigger: 'click',
content: function() {
var content = $(this).attr("data-popover-content");
return $(content).children(".popover-body").html();
},
title: function() {
var title = $(this).attr("data-popover-content");
return $(title).children(".popover-heading").html();
}
});
}
And whenever you add an element to the page that should have a popover, you simply call the function, with a selector for the element. Example for the element you have in your code:
addPopover("[data-toggle=popover]");
In your code, you are configuring the popover on click event of the button.
So, this is how it happens.
Click the anchor link
Initialize the popover with options. (This doesnt mean it displays the popover, it is just a initialization)
Click on the popover again (Popover is already bound because of the earlier call and then it shows)
Also, you need to ensure the popover is not bound to the element again and again to avoid repeated popover bindings.
$('#resultContent').on('click', '#testpop', function(e) { //use on if jQuery 1.7+
// Enables popover #2
$("[data-toggle=popover]").popover({
html: true,
content: function() {
var content = $(this).attr("data-popover-content");
return $(content).children(".popover-body").html();
},
title: function() {
var title = $(this).attr("data-popover-content");
return $(title).children(".popover-heading").html();
}
}).popover('show');
// Explicitly show the popover.
});

How can call the jquery function onclick only parent element [duplicate]

This question already has answers here:
How to stop events bubbling in jQuery? [duplicate]
(5 answers)
Closed 7 years ago.
I am trying to call a jQuery function when clicked only on parent element.
<div id="clcbox" class="click-img">
<img id="fire" onclick="createFirework()" src="img/clicker.png" />
</div>
I have an img tag inside a div. When I click on the div it should call one function and when I click on the img I want to call another function. How can I do this?
$('.click-img, .wishes').click(function () {
$('.flipWrapper').find('.card').toggleClass('flipped');
return false;
});
When I click the div I should call the above function. However now when I click on the image, it is also calling this function and createFirework().
The issue is due to event bubbling. If you attach your events in an unobtrusive manner you can easily stop this behaviour.
<div id="clcbox" class="click-img">
<img id="fire" src="img/clicker.png" />
</div>
$('#fire').click(function(e) {
e.stopPropagation();
createFirework();
});
$('.click-img, .wishes').click(function (e) {
$('.flipWrapper').find('.card').toggleClass('flipped');
e.preventDefault();
});
First off, don't mix inline (onclick) event handlers and jQuery event handlers. Once, you've got a jQuery event handler in place of your createFirework method, you simply stopPropagation to stop it calling the handler on the outer div.
Below is an example
$('.outer').click(function(e){
alert("You clicked text in the div");
});
$('.inner').click(function(e){
alert("You clicked the button, but the div event handler will not fire");
e.stopPropagation();
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="outer">
<span>here is some text inside the div, click it</span>
<button class="inner">Click me</button>
</div>
You need to use stopPropagation function:
http://www.w3schools.com/jquery/event_stoppropagation.asp
In your case you need to add this on image click event:
$('.click-img, .wishes').click(function (event) {
event.stopPropagation();
$('.flipWrapper').find('.card').toggleClass('flipped');
return false;
});
It looks like you need to stop the click event from the image bubbling up the DOM chain.
$('.click-img, .wishes').click(function (e) {
$('.flipWrapper').find('.card').toggleClass('flipped');
e.stopPropagation();
});
When you click on the image, that event is passed up to it's parent, in this case the <div>. That is by behavior. To stop that from ocurring, you call the stopPropagation() function that is part of the incoming event argument for the click event.
You can use Event.stopPropagation(), to stop the click event bubble to its parents, but you also need to add a param event, so your function can access it without browser issue.
// VVVV pass `event` as createFirework's param.
<img id="fire" onclick="createFirework(event)" src="http://placehold.it/50x50" />
But I'd suggest that answers that separate js part and html part would be better. Just like Jamiec's.
function createFirework(event) {
console.log('inner');
event.stopPropagation();
}
$('.click-img, .wishes').click(function () {
console.log('outer');
return false;
});
#clcbox {
width: 100px;
height: 100px;
border: solid 1px black;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="clcbox" class="click-img">
<img id="fire" onclick="createFirework(event)" src="http://placehold.it/50x50" />
</div>

Change onclick handler of the element added dynamically after the page has loaded

I have the following DOM structure.
<div class="purchase-section">
<div class="purchase">
<input type="submit" id="add-to-cart" class="btn" name="add" value="Add to Cart"> <span class="rc-or">Or</span>
<button class="btn rc-button" id="btn-buy-now" onclick="event.preventDefault(); window.location='https://example.com?productId=681';">Buy Now - 3 installment</button>
</div>
</div>
The button element is added by a script which runs after the page has loaded. I need to change the onclick handler for this button. I tried following but it doesn't work.
$(document).ready(function() {
$('.purchase-section').on('change', '.purchase', function(){
$("#btn-buy-now")[0].onclick = null;
$("#btn-buy-now").click(function() { alert("done") });
});
});
Can anyone please help me with this?
Use $("#btn-buy-now").removeAttr("onclick"); to remove onclick completely and then delegate event to dynamically added element.
$("static_parent").on("event", "dynamic_element", function () {
});
$(".purchase").on("click", "#btn-buy-now", function () {
/* code */
});
Try this:
$(document).ready(function() {
$(".purchase-section").find("#btn-buy-now").removeAttr('onclick');
$(".purchase-section").find("#btn-buy-now").click(function(e) {
e.preventDefault();
alert("done");
});
});
However, it depends on when this element is loaded. You will need to ensure your button is already in the DOM before this script executes, otherwise this may not be effective.

remove/toggle class when users clicks on the link

I have 3 or so button in my page which i need to show a social icon when user clicks on those links.
I used this jQuery
$('.one').on('click', function() {
$('.smenu').not($(this).next()).removeClass('share')
$(this).next().toggleClass('share');
});
<div id="sharing_area">
<ul class='smenu'>
<li class="facebook"><a target="_blank" onclick="return windowpop(this.href, 545, 433)" href="https://www.facebook.com/sharer/sharer.php?u=http://youtu.be/<? echo $id_3 ?>"><i class="icon-facebook"></i></a></li>
</ul>
<span class="one">Share</span>
</div>
I keep getting error, but i don't know what i'm doing wrong.
Can you guys help me out?
Here is my DEMO
There is no .next() element for the span you are clicking! Your UL is before the span, so you need prev():
http://jsfiddle.net/TrueBlueAussie/5dsrk470/5/
$('.one').on('click', function() {
console.log('click');
$('.smenu').not($(this).prev()).removeClass('share')
$(this).prev().toggleClass('share');
});
If you want to remove the class on clicking the links add this delegated event handler:
$(document).on('click', 'a', function(){
$('.smenu').removeClass('share')
});
Looks like you confused prev and next methods:
var $smenu = $('.smenu');
$('.one').on('click', function () {
$smenu.removeClass('share');
$(this).prev().toggleClass('share');
});

Delegate/Live Failure. Can't bind events after Prepending an element

EDIT--- I realized that the problem here was that the click handler that was bound to the element had to be unbound before I could bind another click handler handler.
I want to allow the user to select/unselect items by click on the element in question. The elements start in an "options" box and if clicked, move to a "selected box". If they are then clicked in the selected box, the elements move back to the original options box.
Can't figure out why delegate() and live() are not working here. I assume this has to do with prependTo() or appendTo().
$('#amen_options .options p').click(function(e){
$(this).appendTo('#amen_selected .options');
e.stopPropagation();
e.preventDefault();
});
/*
$("body").delegate('#amen_selected p', 'click', function(e){
#(this).appendTo('#amen_options .options');
e.stopPropagation();
e.preventDefault();
});
*/
$('div#amen_selected div.options p').live('click',function(e){
$(this).appendTo('#amen_options .options');
e.stopPropagation();
e.preventDefault();
});
Here's the markup:
<div>
<div id="amen_options">
<h3>Click to Select</h3>
<div class="options">
<p data-option="">One</p>
<p data-option="">Two</p>
<p data-option="">Etc...</p>
</div>
</div>
<div id="amen_selected">
<h3>Selected</h3>
<div class="options">
</div>
</div>
The first click works (sending p elements from options to selected box). Once in selected, though, no event handlers are binding. The firebug console isn't showing an error. Normally, I'd assume that this is a markup problem, but I've checked it repeatedly.
Thanks!
It looks like delegate() works good.
http://jsfiddle.net/fLXgU/1/
$('body').delegate('#amen_options .options p', 'click', function(e) {
$(this).appendTo('#amen_selected .options');
return false;
});
$('body').delegate('#amen_selected .options p', 'click', function(e) {
$(this).appendTo('#amen_options .options');
return false;
});
