I am new in using jquery. I am trying add in the simplemodal.js (Eirc Martin's simple modal) a function called 'jBox' that will take the data (ie link) and options and using ajax will load the content into the modal container. This way I want on my pages in several places easy call this function
jBox = function(address, options){
$.get(address, function(data) {
$.modal(data);
});
};
});
The code is working fine, but i would like to add a loading image before the content is fully loaded. There is a lots of similar posts about loader/ spinner in simplebox but none of the works for me.
I was trying following code
$('#test').load('<img src="loader.gif">').html(data);
$('#test').modal();
But, some way, it doesnt work for me. Any ideas what I am doing wrong? Thanks
I use the ajaxStart and ajaxStop events.
$("body").on({
ajaxStart: function() {
$(this).addClass("loading"); // so page knows it's in loading state
// .. your modal code
},
ajaxStop: function() {
$(this).removeClass("loading"); // not it loading state anymore
// .. What you should do if loading is done. (eg. hide modal)
}
});
In this case I set the body class to 'loading'. So you can do some magic in css if you like.
I tend to use it to disable forms as well.
body.loading div.some-class {
// your special style for during loading
}

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.

I am using backbone.js and trying to stay strict to the model-view-controller structure as I learn it. I have an onclick function for a link in one of my views that I am not sure where to put. Is the best place to keep this in the render function of the view?
Thanks
More specifically, the onclick performs a facebook login and then adds the user to my database if they are not currently in it. Don't know if this changes anything.
Here is what I think I will go with:
var NewUserView = Backbone.View.extend({
el: $('#window'),
render: function(){
// Render
this.listeners();
},
listeners: function(){
// onclick and other listeners
}
});
From the Backbone documentation:
In Backbone, the View class can also be thought of as a kind of
controller, dispatching events that originate from the UI, with the
HTML template serving as the true view. We call it a View because it
represents a logical chunk of UI, responsible for the contents of a
single DOM element.
Here's the general way to handle events in Backbone:
var NewUserView = Backbone.View.extend({
el: $('#window'),
render: function() {
// Render
},
events: {
"click #facebookButton": "loginViaFacebook"
},
loginViaFacebook: {
// Perform facebook login and add user to database
}
});
Where do you want the link to appear? On View page right? So , you should keep it in the same view on which you want the link to appear.
But , if you are building an architecture rather than just a web application, then you should put the onclick function in some different file where you will keep all these function and then import them in the view as required or keeping them in separate files and bundling them for import on view page.
Please make a file and write all the functions in that file and include that file in the your view file and use the onClick in the anchor tag. Please let me know if this make sense.
I have a web application that loads javascript on page load:
$(function() {
$('.modal-delete').click(function() {
alert();
});
});
I have a html page with a series of buttons which alert a blank message box when they're clicked:
<button class="modal-delete btn danger"></button>
which works fine.
However, a have some AJAX calls that generate more buttons just like the ones above but NOT on page load! They can be created at any time. These buttons do not do anything but they're meant to load the alerts. They're identical but because they never existed on page load, the Jquery code doesn't work on these buttons. How do I attach the same code to these buttons too?
Many thanks :).
I think you'll want jQuery's 'live()' function:
$('.modal-delete').live('click', function() {
alert();
});
This binds to the elements which match but also rebinds when new elements are added in the future:
"Attach an event handler for all elements which match the current selector, now and in the future"
Change the ready code to this...
$(function() {
$("document").on("click", ".modal-delete", function() {
alert("click");
});
});
So i I have a page that contains links that call an httpRequest. The request calls a php file that grabs data from mysql and pre populates a form which is then returned to the browser/webpage. My problem is that when the page is returned to the browser via the httpRequest/ajax the text area does not display the tinymce editor, it just displays a normal text area. It looks like my request and ajax is working fine the text area just doesn't have the tinycme editor on it.
When i don't use ajax it works fine but when i put it in a separate file and call it via ajax it doesn't bring in the tinymce editor.
Does anyone know how to fix this problem so that my ajax generated page displays the text area with the tinymce editor. Thank you.
Lets presume that your thinyMCE instance is initialized with code below
// initialize tinyMCE in page
tinyMCE.init({
mode: "textareas",
theme: "advanced"
});
and you have some kind of button somewhere in the page. For purpose of this tip, i will not give it any ID but you may. Now, using jQuery you can easily attach event handler to that button which will call through AJAX your server and take content which you want to put tinyMCE editor. Code which will do such job would look somehow like below.
$(function() {
$("button").bind("click", function() {
var ed = tinyMCE.get('content');
ed.setProgressState(1); // Show progress
$.getJSON('/page/12.json', { /* your data */
}, function(data) {
ed.setProgressState(0); // Hide progress
ed.setContent(data["body"]);
}
});
});
});
You can see that on button.click ajax will call url /page/12.json which will return JSON as response. bare minimum of that response could be:
{
title: "Page title",
body: "<html><head><title>Page title</title>......</html>"
}
I attached anonymous function as callback which will handle response from server. and hide progress indicator which is shown before ajax call.
About JSON
JSON is shorten of JavaScript Object Notation. It is JavaScript code!!! So don't be confused about it. Using JSON you can make javascript object which can have attributes you can use later in your code to access particular peace of data which that object "holds". You can look at it as some kind of data structure if it is easier to you.
Anyway, to show you how this JSON can be created by hand look at examples below
var data = new Object();
data.title = "Page title";
data.body = "<html....";
or
var data = {
title: "page title",
body: "<html...."
};
it is very same thing.
If you want to learn more about JSON point your browser to http://json.org.
===== alternative =====
Alternative to json solution could be just plane ajax call to server and response can be plain HTML (from your question I can assume that you have something like this already). So instad of calling $.getJSON you can use $.get(url, callback); to do same thing. The code at the top of my answer will not dramatically change. Instead of geting JSON in response you will get string which is HTML.
----------- BOTTOM LINE -------
I prefer JSON since it can be easily extended later with other attributes, so there is no painful code changes later ;)
Problem here will be that when you return the full page and render it using the ajax response, your tinymce instance has not been shut down before.
In order to do this you can call this small piece of code before you render the ajax response:
tinymce.execCommand('mceRemoveControl',true,'editor_id');
In this case the editor should initialize correctly. You are not allowed to initialize a tinymce editor with the same id before shutting the first one down.
Strangely i ran into this problem yesterday. Following code should work, but YMMV. Trick is to use the correct steps in ajax events. I used the Regular TinyMCE and made use of the jQuery library already included.
Following goes into your tinyMCE initialization tinyMCE.init() . All of the below block should be outside the document.ready.
myTinyInit = {
//.......All essential keys/values ...........
setup : function(ed) {
ed.onChange.add(function( ed ) {
tinyMCE.triggerSave();
}) }
//.....................
};
// Init the tinyMCE
tinyMCE.init(myTinyInit);
This ensures the content is being saved regularly onto the textarea that holds the value. Next step is setting up the request events.
Normally tinyMCE mceAddControl before the ajax post and mceRemoveControl after the ajax success should do the trick. But I found that often does not work.
I used the form as the jQuery selector in my case.
jQuery( '.myForm' )
.find( 'textarea#myTextArea' )
.ajaxStart(function() {
// If you need to copy over the values, you can do it here.
// If you are using jQuery form plugin you can bind to form-pre-serialize event instead.
// jQuery( this ).val( tinyMCE.get( jQuery( this ).attr( 'id' )).getContent() );
}).ajaxSend( function() {
// ! - step 2
// My case was multiple editors.
myEds = tinyMCE.editors;
for( edd in myEds ) {
myEds[ eds ].remove();
}
// tinyMCE.get( 'myTextarea' ).remove();
// strangely mceRemoveControl didnt work for me.
// tinyMCE.execCommand( 'mceRemoveControl', false, jQuery( this ).attr('id'));
}).ajaxSuccess(function() {
// Now we got the form again, Let's put up tinyMCE again.
txtID = jQuery( this ).attr( 'id' );
// ! - step 3
tinyMCE.execCommand( 'mceAddControl', false, txtID );
// Restore the contents into TinyMCE.
tinyMCE.get( txtID ).setContent( jQuery( this ).val());
});
Problems i came across :
Using mceRemoveControl always gave me r is undefined error persistently.
If you get a blank tinyMCE editor, check the DOM whether the ID of the textarea is replaced with something like mce_02, this means that TinyMCE is being initialized again or something is wrong with the order. If so, the tinyMCE is duplicated with each save.
if you are new to JS, I recommend using jQuery with the form plugin, it might be easier for you. But do use the regular non-jquery tinyMCE, as it is well documented.
I fixed this problem by recalling the function after the ajax call. In this part of my ajax:
if (xmlhttp.readyState==4 && xmlhttp.status==200)
{
document.getElementById("Content").innerHTML=xmlhttp.responseText;
tinymce();
Now it works fine.
I have this issue. I'm working on a jquery ajaxed site. I have the main content div in the middle and on top the navigation. I need to AJAX the content, because I have flash backgound so that the flash video won't start from beginning after every page load. The only way I was able to do this was with this sort of code:
$(document).ready(function(){
$.ajaxSetup ({
cache: false
});
//For loading
var ajax_load = "<img src='img/load.gif' alt='loading...' /><p>";
// Var
var loadPage1 = "page1.html";
// Load page
$("#page1").click(function(){
$("#content").hide(2000);
$("#content").html(ajax_load).load(loadPage1);
$("#content").show(2000);
});
All other ways to get the div didn't work because there was issues on getting plugins etc. working in the ajaxed div (content).
So... everythig is working fine - but, the div loads it's content from page1.html and shows it and only after this does it hide it and show it. So it loads the page and then does the effects I want to.
Do I need to queue this some how or what's the proper jquery way? I tried delay, stop etc.. but can't seem to solve this out. It's propably very simple.
Thanks.
Show the element in the load callback handler.
i.e:
$("#page1").click(function(){
$("#content").hide();
$("#content").html(ajax_load).load(loadPage1, function(){
$("#content").show(2000)
});
});
.load() takes 2 arguments, the URI and a callback to fire after load.
API is found here: http://api.jquery.com/load/
function() {
$("#content").hide(2000);
$("#content").html(ajax_load).load(loadPage1, function() {
$("#content").show(2000);
});
}
