I'm using codeigniter and when selecting a dropdown form onchange works and i get my second field ok(Country->City).
When i submit the form with errors, the page reloads with the errors displayed but my onchange stops working.
Any ideas for what's going on?
Hmm, here's what i'm doing. User get's to homepage and fills the form, the onchange is working. User then submits the form with an error and i check the validation and load a new page(register) with the same onchange function. I tried to change the function name (getLocal) to another name but the result is the same. Tried to use live.("change", getLocal) and the result is the same, no firing on the register page...
function getLocal(){
$("#city").load("home/ajaxlocal", {country: $(this).val()} );
//alert($(this).val());
return false;
}
..............
$js = 'id="country"';
$(document).ready(function() {
$("#country select").bind("change", getLocal);
});
td echo form_label('Country :', $country);
td id="country">echo form_dropdown('country', $country,$ct,$js);
IF yo arent reloading the page, but reloading elements with AJAX, the jquery will not bind to those new elements if you specify them in the ready() function.
$(document).ready(function() {
$("#country select").bind("change", getLocal);
});
This is loading this onload - try using .live()
http://api.jquery.com/live/
This method is a variation on the basic .bind() method for attaching event handlers to elements. When .bind() is called, the elements that the jQuery object refers to get the handler attached; elements that get introduced later do not, so they would require another .bind() call.

I am using Shopify "Streamline Theme" with quick product view and I recently added infinite scroll to products on each collection using Ajaxinate.js.
When I open a collection page it loads with some products which is supposed to do, The products already there work fine with quick view and quick add to cart and also.
The Infinite scroll works fine and it loads new product fine but the problem is raised when the new products loaded through AJAX call doesn't have work with the quick view function.
I have tried to create a callback function to activate the quick view with no success, using the theme initialisation code with no success.
function callBack(){
theme.init();
theme.initQuickShop();
};
document.addEventListener("DOMContentLoaded", function() {
var endlessClick = new Ajaxinate({
method: "scroll",
loadingText: 'Loading...',
callback: callBack
});
});
Edit -------
My problem, is that when the page is loaded only the initial loaded products quickview elements are loaded in the DOM. When the scroll more button is clicked, the newly loaded products are loaded without their respective quickview elements. Hence why the quickview does't work for them. The theme.js file comes with this initialisation code:
theme.reinitProductGridItem = function($scope) {
if (AOS) {
AOS.refreshHard();
}
if (theme.settings.currenciesEnabled) {
theme.currencySwitcher.ajaxrefresh();
}
// Reload quick shop buttons
theme.initQuickShop(true);
// Refresh reviews app
if (window.SPR) {
SPR.initDomEls();SPR.loadBadges();
}
// Re-register product templates in quick view modals.
// Will not double-register.
sections.register('product-template', theme.Product, $scope);
// Re-hook up collapsible box triggers
theme.collapsibles.init();
};
I have tried to integrate this into a callback but no success, the quickview modal doesn't seem to load for the newly loaded products:
function callBack(){
ReloadSmartWishlist();
var $container = $('#CollectionSection');
theme.reinitProductGridItem($container);
// I have tried the following init qith no success:
// theme.init();
// theme.initQuickShop(true);
// theme.initQuickShop();
// sections.register('product-template', theme.Product, $container);
// AOS.refreshHard();
};
document.addEventListener("DOMContentLoaded", function() {
var endlessClick = new Ajaxinate({
method: "click",
loadingText: 'Loading...',
offset: 0,
callback: callBack
});
});
I am missing something but what? :/
Note for other things like loading products images with the callback and the wishlist app, it works as intended...
When you load elements via AJAX and if the events are not attached to a parent element that is not removed from the DOM, those elements will not have an attached event to them.
The term used here is event delegation.
Here is an example of non-delegated event:
document.querySelectorAll('a').addEventListener('click', function(){
// Do something
})
Since you are attaching the event to the existing "a" elements if you add new 'a' via AJAX those elements will not have the event since Javascript already attached all the events and it will not reattach them if you don't specifically recall them again.
Here is an example of a delegated event:
document.querySelector('body').addEventListener('click', function(target){
let target = event.target;
if (target.tagName === 'A'){
// Do something here
}
})
Where we attach the event to the body tag ( where it's a better idea to attach it to a closer none-modified parent element of the ajax items ) and once we click we check if our target tag is an "a" and do something then.
So long story short, you will need to delegate the quick cart link so that it works after you load the items via AJAX.
Drip is correct you need to delegate your event, but for people like me it's hard to completely understand how to do that.
I'm not sure how your quickview is structured, but if you open it with a .click function and can use jquery use the [.on() function][1].
For example: I use a quickview that opens on a button click. My button is attached to my product-grid-item.liquid with this bit of code:
<div class="quick-view-button">
<a class="quick-view" data-handle="{{ product.handle }}" href="javascript:void(0);">Quick View</a>
</div>
My quickview function originally looked like this:
function quickView() {
$(".quick-view").click(function () {
//all of the quickview code
What happens is exactly like you described. The event listeners only loaded on the first product load but nothing after an AJAX load.
Using jquery's .on() binds the event listener to the element meaning when it's loaded in later it'll still have the event. Here's an example of what my code looks like after using .on()
function quickView() {
$('body').on('click','.quick-view',function(){
I really hope this helps you or someone else with this problem.

Im using bootstrap vue:
<b-form-checkbox #change="onoff('concurency_filter')" v-model="concurency_filter.onoff" switch size="lg"></b-form-checkbox>
And I need call ajax with state of this checkbox:
onoff: function (filter) {
axios.put('/api/user/accounts/'+this.account_id+'/togglefilter',
{
filter: filter,
status: this[filter].onoff //here still old value in this.concurency_filter.onoff
}).then(response => {
..........
});
},
But v-model still not changed when ajax is called. When checkbox clicked v-model must toggle true/false, but ajax called before v-model toggle it. How to deal with it?
I know that I can use WATCH in vue, but when first time ajax loading data it's triggering this WATCH event. I want trigger it only on click
Success:
onoff('concurency_filter', $event)
$event will contain exact value of checkbox right after click
I have a datatable which will be model binded when the page opens but when i am doing any edit or delete function the the datatable will be binded using ajax call. So I am having a function
$('#user-detail-datatable tbody tr td a').on('click', function () {
//prepoluting values on edit
$("#CarryUser").val($(this).closest('tr').find('td')[5].outerText);
d = $(this).closest('tr').find('a')[1].id;
$("#display").val($(this).closest('tr').find('td')[6].outerText);
UsingBranchId = $(this).closest('tr').find('td')[2].outerText;
$("#fileUpload").val($(this).closest('tr').find('td')[0].outerText);
});
used to get the values from datatable to bind a model which will open on click of edit button. but this function is not getting hit after I am editing or deleting can anyone explain why. And help me out
You would need to use a delegated event handler. As for now you have one time binding to elements which is lost as soon the table is updated. Use
$('#user-detail-datatable').on('click', 'tbody tr td a', function () {
}]
instead.
I am using RenderPartial to generate CListView and all the contents generated properly and good pagination is working fine too. But when I added my custom JS to elements generated by the CListview it works fine for the the fist page content but when i use pagination and click to page 2 then the JS binding fails.
Is there any other way to bind custom event to elements generated in YII CListview I had tried using live, and on nothing work for me here is my js file.
I think I have to call my function on every ajax load in but how can I achieve in yii
This is the script I am using to update ratings on server with button click and this the element for which these forms and buttons are defined are generated by CListview in yii
$(document).ready(function(){
$('form[id^="rating_formup_"]').each(function() {
$(this).live('click', function() {
alert("hi");
var profileid= $(this).find('#profile_id').attr('value');
var userid= $(this).find('#user_id').attr('value');
console.log(userid);
var data = new Object();
data.profile_id=profileid;
data.user_id=userid;
data.liked="Liked";
$.post('profile_rating_ajax.php', data, handleAjaxResponse);
return false;
});
});
});
You can also try CGridView.afterAjaxUpdate:
'afterAjaxUpdate' => 'js:applyEventHandlers'
The $.each method will loop only on existing elements, so the live binder will never see the ajax-generated content.
Why don't you try it like this:
$(document).ready(function(){
$('form[id^="rating_formup_"]').live('click', function() {
alert("hi");
var profileid= $(this).find('#profile_id').attr('value');
var userid= $(this).find('#user_id').attr('value');
console.log(userid);
var data = new Object();
data.profile_id=profileid;
data.user_id=userid;
data.liked="Liked";
$.post('profile_rating_ajax.php', data, handleAjaxResponse);
return false;
});
});
This problem can be solved by two ways:
Use 'onclick' html definitions for every item that is going to receive that event, and when generating the element, pass the id of the $data to the js function. For example, inside the 'view' page:
echo CHtml::htmlButton('click me', array('onclick'=>'myFunction('.$data->id.')');
Bind event handlers to 'body' as the framework does. They'll survive after ajax updates:
$('body').on('click','#myUniqueId',funcion(){...});
I'm using jQuery UI. I'm loading some content in a dialog box over AJAX. After inserting the content from the server, I need to make modifications to the document. I am using the .live() function on my link; I thought this would enable me to use Js after loading the content over ajax, but it's like the content I just loaded isn't a part of the document. Any help very much appreciated.
Are you adding the bindings (lives) in the success function of the ajax call?
If so I had the same issue, I'll try to explain what I figured out:
$.post('callURL', function(data){
// Let's say data returned from server is an ID of a div I have to hide
// by clicking on some_link
$('#some_link').live('click',function(){
$('#'+data).hide();
});
});
This won't work because the code inside the 'live' function is executed on click and at that time the 'data' value is gone.
To make it work I made a global variable 'ID' which I set in the success function and then called in the 'live' function again like this:
var ID;
$.post('callURL', function(data){
// Let's say data returned from server is an ID of a div I have to hide
// by clicking on some_link
ID = data
$('#some_link').live('click',function(){
$('#'+ID).hide();
});
});
