How to wrap a container div around a Ckeditor table onOk

When a user enters a table on the Ckeditor, I want to wrap a div around it with a class but I can't find a way to get this table HTML element. What is the best way to go about it?
I've tried creating a plugin to extend the table dialog onOk function (see code). This gives me all the properties from the table dialog but I don't want to have to create the whole table element again with all the properties as I don't want to re-write the existing table plugin.
I just need to get the code this plugin adds and wrap it in a div.
I thought about doing it in my projects javascript, when page loads, get all tables and wrap it in a div. However, this doesn't seem like the best way to do it at all. I thought there must be a way via ckeditor?
CKEDITOR.plugins.add( 'responsivetables', {
// The plugin initialization logic
init: function(editor) {
vsAddResponsiveTables(editor);
}
});
function vsAddResponsiveTables(editor){
CKEDITOR.on( 'dialogDefinition', function( ev ) {
var dialogName = ev.data.name;
var dialogDefinition = ev.data.definition;
if ( dialogName == 'table') {
addTableHandler(dialogDefinition, editor);
}
});
}
function addTableHandler(dialogDefinition, editor){
dialogDefinition.onOk = function (a) {
// get table element and wrap in div?
}
}

I found the answer so for anyone else that needs it, this is what I did:
I used the insertElement event instead of when dialog was closed, only doing what I need if its a table that's being added.
// Register the plugin within the editor.
CKEDITOR.plugins.add( 'responsivetables', {
// The plugin initialization logic goes inside this method.
init: function(editor) {
vsAddResponsiveTables(editor);
}
});
function vsAddResponsiveTables(editor){
// React to the insertElement event.
editor.on('insertElement', function(event) {
if (event.data.getName() != 'table') {
return;
}
// Create a new div element to use as a wrapper.
var div = new CKEDITOR.dom.element('div').addClass('table-scroll');
// Append the original element to the new wrapper.
event.data.appendTo(div);
// Replace the original element with the wrapper.
event.data = div;
}, null, null, 1);
}

To the previous answer by 'gemmalouise' need to add one more line of code
CKEDITOR.editorConfig = function( config ) {
config.extraPlugins = 'responsivetables';
}
Otherwise it will not work (I cannot indicate this in the comment, because lack of 50 reputation).
And more compact code of this fuctional:
CKEDITOR.plugins.add('responsivetables', {
init: function (editor) {
editor.on('insertElement', function (event) {
if (event.data.getName() === 'table') {
var div = new CKEDITOR.dom.element('div').addClass('table-scroll'); // Create a new div element to use as a wrapper.
div.append(event.data); // Append the original element to the new wrapper.
event.data = div; // Replace the original element with the wrapper.
}
}, null, null, 1);
}
});

How to prevent a user from being redirected to a link in JavaScript?

var $ = function (id) {
"use strict";
return document.getElementById(id);
};
$(document).ready(function () {
"use strict";
$('redirect').click(function () {
window.alert('you clicked the link');
return false;
});
});

I have a link in HTML and I wanting to use JavaScript and Jquery for the rest of my code. When the user clicks on the link, I want an alert to pop up with a message but I do not want the link to redirect them to that page. When I view my code in Chrome with the developer tools, I get an error message that says "Uncaught TypeError: cannot read property of 'ready' of null". Why is the ready property coming up null and how do I fix it?
var $ = function (id) {
"use strict";
return document.getElementById(id);
};
$(document).ready (function () {
"use strict";
$('redirect').click(function () {
window.alert('you clicked the link');
return false;
});
});

You need to use e.preventDefault(), like this:
$(document).ready(function () {
$('#redirect').click(function (e) {
e.preventDefault();
window.alert('you clicked the link');
});
});
Also, if you need to reference elements by class (with jQuery):
$('.someClass').on('click', function() {
...
If you want to access them
by id:
$('#someId').on('click', function() {
...

Your issue is you're redefining jQuery's $ function to your own custom function. Don't do this! It completely nullifies jQuery (you'd have to use the verbose jQuery form). You can also use preventDefault to prevent the hyperlink changing your page.
$(document).ready(function () {
"use strict";
$('redirect').click(function(e) {
e.preventDefault();
window.alert('you clicked the link');
});
});
Also make sure you have jQuery - place this at the top of your page:
<script src="https://code.jquery.com/jquery-3.3.1.js"></script>

var $ = function (id) {
"use strict";
return document.getElementById(id);
};
If you use $ as your jQuery wrapper, then the code above override that variable. Meaning it's no longer jQuery but rather that custom function that you have set. Try changing the name of the function or variable above.

JQuery detect widget attached

I have a web application with a medium amount of ajax requests.
I load all jquery and jquery widgets on head then i load my base.js before close body tag.
function baseScripts() {
$(".open-dialog").click(function (event) {
event.preventDefault();
event.stopPropagation();
alert("Opening dialog");
href = $().buildUrl($(this).attr("href"), "&isAjax=true");
$().createDialog(href, "Window Title");
return false;
});
$("input:hidden.select").each(function () {
var element = $(this);
if (!($("#s2id_" + element.attr("id")).length)) {
$(element).select2({
// select2 properties...
});
}
});
}
}
SCRIPT BLOCK TO LOAD BASE SCRIPTS ON EVERY AJAX REQUEST
$(document).ajaxComplete(baseScripts);
The problem is after every ajax request the base scripts its called again and them opening dialog multiple times and attaching select2 multiples times too.
How i can detect if widget is already attached into element or class?
Execute scripts on every ajax request (like i did) its a bad pratice?

It doesn't make sense that you will want to re-bind the click event and select2 on ajaxComplete. They should be a one-time binding, in which case, you can just do:
$(document).ready(function(){
baseScripts();
function baseScripts() {
$(".open-dialog").click(function (event) {
event.preventDefault();
event.stopPropagation();
alert("Opening dialog");
href = $().buildUrl($(this).attr("href"), "&isAjax=true");
$().createDialog(href, "Window Title");
return false;
});
$("input:hidden.select").each(function () {
var element = $(this);
if (!($("#s2id_" + element.attr("id")).length)) {
$(element).select2({
// select2 properties...
});
}
});
}
});

Jquery simple ajax - Insert html

When a div is opnened i want to load html content into it via ajax. This is the code im working with:
http://jsfiddle.net/uhEgG/2/
$(document).ready(function () {
$('#country').click(function () {
$("#country_slide").slideToggle();
});
$('#close').click(function (e) {
e.preventDefault();
$('#country_slide').slideToggle();
});
});
The code I think I need is this:
$.ajaxSetup ({
cache: false
});
var ajax_load = "Loading...";
var loadUrl = "www.test.com/site.html";
$("#load_basic").click(function(){
$("#country_slide").html(ajax_load).load(loadUrl);
})
How can I make it work to make it load up when the div is opened by the code above, firstly because it is setup for a click function not a toggle function, and second, because the toggle doesn't seem to be able to distinguish if the div is open or not.

to make it load up when the div is opened by the code above
$("#country_slide").slideToggle(function(){
if($(this).is(':visible')){
$("#country_slide").html(ajax_load).load(loadUrl);
}
});

Try to delegate the events.. Looks like the element is not yet available in the DOm when the event is bound
Replace
$('#country').click(function () {
with
$(staticContainer).on('click', '#country', function () {
staticContainer is the element which is already in your DOM when the event is bound and the ancestor of country

Either store the slide state in a variable or in a data attribute liek this:
<div id="country_slide" data-state="1">
And make something like this:
$('#country').click(function () {
$("#country_slide").slideToggle();
if ($("#country_slide").attr("data-state") == 0)
$("#country_slide").html(ajax_load).load(loadUrl);
});

Toggle window.location in jQuery/javascript

What I am trying to achieve is that whenever you click an image, it changes the window.location url, toggling it between '#' and '#footer'. Right now, all I have is this:
<script>
function clickarrow(){
var rd=Math.floor(Math.random()*11)
if (rd > 5){
window.location="#footer";
}
else{
window.location="#";
}
}
</script>
As you can see, this makes a 50:50 chance of either change being made. It works as a temparary fix, but sometimes you have to click up to 6 times for it to take effect.
Is there a way of doing this that properly toggles the window.location?
I am using jQuery 1.9.

If you're trying to reliably toggle the hash, rather than using a random chance, try something like this:
function clickarrow(){
var showFooter = true;
return function () {
if (showFooter) {
window.location.hash = "footer";
} else {
window.location.hash = "";
}
showFooter = !showFooter;
}
}
jQuery(function () {
jQuery('#myToggleLink').click(clickarrow());
});
Note: Normally when binding events, a function reference must be passed in. Here, I'm invoking clickarrow() since it returns a function by design. The returned function encapsulates the toggle variable via closure.

you can use data attribute to tell what is next step:
$('#arrow').click(function() {
if ($(this).data('footer'))
{
window.location="#footer";
$(this).data('footer', 'false');
alert('b');
}
else
{
window.location="#";
$(this).data('footer', 'true');
alert('a');
}
});
