Change div content after its clicked and clicked again

This is the jQuery code that basically opens and closes a div:
jQuery('#filter_werk').find('.raven-sortable').addClass('opened');
var toggle = document.getElementById('deknop');
var slider = document.querySelector('.raven-sortable');
toggle.addEventListener('click', toggleSlider, false);
function toggleSlider(){
if (slider.classList.contains('opened')) {
slider.classList.remove('opened');
slider.classList.add('closed');
} else {
slider.classList.remove('closed');
slider.classList.add('opened');
}
}
</script>
What I'm trying to do is change the content of the following div from "FILTER +" to "FILTER -" and back again to "FILTER +" when its clicked again
<div id="deknop">FILTER +</div>
Could this be done without breaking the current jQuery code?
Thank you!

As I understood the function toggleSlider works fine so try:
function toggleSlider(){
if (slider.classList.contains('opened')) {
slider.classList.remove('opened');
slider.classList.add('closed');
toggle.innerHTML = "FILTER +";
} else {
slider.classList.remove('closed');
slider.classList.add('opened');
toggle.innerHTML = "FILTER -";
}
}

You can add some logic to your toggleSlider() function that will change your #deknop text based on what it currently is (either ‘FILTER +’ or ‘FILTER -‘ like this:
function toggleSlider(){
$('#deknop').html($('#deknop').text() == 'FILTER +' ? 'FILTER -' : 'FILTER +');
if (slider.classList.contains('opened')) {
slider.classList.remove('opened');
slider.classList.add('closed');
} else {
slider.classList.remove('closed');
slider.classList.add('opened');
}
}

Well,
if I had to do this jQuery-style, I would either way try to separate the data from the view. Something like:
(() => {
const state = {
sliderOpen: true,
};
const $slider = $('.raven-sortable');
const $toggle = $('#deknop');
const updateView = () => {
if (state.sliderOpen) {
$slider.addClass('opened').removeClass('closed');
} else {
$slider.addClass('closed').removeClass('opened');
}
$toggle.text(`FILTER ${state.sliderOpen ? '+' : '-'}`);
};
const onToggleClick = () => {
state.sliderOpen = !state.sliderOpen;
updateView();
};
$toggle.click(onToggleClick);
updateView();
})();
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<button class="raven-sortable">Raven sortable</button>
<button id="deknop"></button>

How to run 2 js functions

I have 2 function that I am trying to run, one after another. For some reason they both run at the same time, but the second one does not load properly. Is there a way to run the first function wait then run the second function?:

How would I run the first one wait 5 or so seconds and then run the jquery print? I'm having a hard time with this. So the id would run first and then the print would run adter the id="abc" Here is an example of the code in use:
<div id="test">
<button id="abc" class="btn" onclick="jQuery.print(#test1)"></button>
</div>

If I understand your problem correctly, you want the jQuery click function to be run first, making a div with id="test1" visible and then, once it's visible, you want to run the onclick code which calls jQuery.print.
The very first thing I will suggest is that you don't have two different places where you are handling the click implementation, that can make your code hard to follow.
I would replace your $('#abc').click with the following:
function printDiv(selector) {
$(selector).show();
window.setTimeout(function () {
jQuery.print(selector);
}, 1);
}
This function, when called, will call jQuery.show on the passed selector, wait 1ms and then call jQuery.print. If you need the timeout to be longer, just change the 1 to whatever you need. To use the function, update your example html to the following:
<div id="test">
<button id="abc" class="btn" onclick="printDiv('#test1')"</button>
</div>
When the button is clicked, it will now call the previously mentioned function and pass it the ID of the object that you want to print.
As far as your second function goes, where you have the comment **//run this second**, you should leave that alone. All it does is extend you jQuery object with the print functionality. You need it to run straight away and it currently does.

Contextual Menu issue in office-fabric-ui on second click

We are working on Office UI Fabric JS 1.2.0. Issue is with context menu having submenu items. When you open Second level, and then click anywhere on menu, first level menu was closing and second menu was re-aligning to Top-Left of page. We couldn't find the solution in next version of fabric also.

The issue gets resolved after overriding two methods from fabric.js of ContextualHost as follows:
fabric.ContextualHost.prototype.disposeModal = function () {
if (fabric.ContextualHost.hosts.length > 0) {
window.removeEventListener("resize", this._resizeAction, false);
document.removeEventListener("click", this._dismissAction, true);
document.removeEventListener("keyup", this._handleKeyUpDismiss, true);
this._container.parentNode.removeChild(this._container);
if (this._disposalCallback) {
this._disposalCallback();
}
// Dispose of all ContextualHosts
var index = fabric.ContextualHost.hosts.indexOf(this);
fabric.ContextualHost.hosts.splice(index, 1);
//Following is original code removed
//var i = ContextualHost.hosts.length;
//while (i--) {
// ContextualHost.hosts[i].disposeModal();
// ContextualHost.hosts.splice(i, 1);
//}
}
};
fabric.ContextualHost.prototype._dismissAction = function (e) {
var i = fabric.ContextualHost.hosts.length;
while (i--) { //New added
var currentHost = fabric.ContextualHost.hosts[i];
if (!currentHost._container.contains(e.target) && e.target !== this._container) {
if (currentHost._children !== undefined) {
var isChild_1 = false;
currentHost._children.map(function (child) {
if (child !== undefined) {
isChild_1 = child.contains(e.target);
}
});
if (!isChild_1) {
currentHost.disposeModal();
}
}
else {
currentHost.disposeModal();
}
}
}
};
Hope this question + answer helps someone looking to override fabric.js original code.

How can I recreate Squarespace's Product Quick View in standard Product View?

Overview
So I'm trying to take functionality from one part of Squarespace's Galapagos commerce template and add it to another but it's proving to be more difficult than I thought.
I need the image-swapping capability of the "Quick View" (example - mouse over any image and click Quick View ) to replace the column of full sized zoomable images in the "Product View" (example - you see this once you click on a product).
So I found the code for each section:
Product View
This code simply goes through each image in the array and spits it out with the id jsProductItemImages which allows it to be hovered and zoomed.
<div class="productitem-images" id="jsProductItemImages">
{.repeated section items}
{.image?}
<div class="productitem-image-zoom-wrapper sqs-image-zoom-area"><img data-load="false" class="productitem-image loading" {#|image-meta} /></div>
{.end}
{.video?}
{#|video}
{.end}
{.end}
</div>
Quick View
I'm not 100% on the logic here, but essentially it's grabbing the first image and making it a hover/zoomable primary image then listing the entire array of images beneath it as thumbnails. I read that the # symbol is the equivalent of saying this in javascript, but I don't get why it's being used to spit out only the first image in the array.
<figure class="ProductItem-gallery">
{.section items}
<div class="ProductItem-gallery-slides">
{.repeated section #}
{.image?}
<div class="ProductItem-gallery-slides-item" data-slide-index="{#index}"><img class="ProductItem-gallery-slides-item-image" data-load="false" {#|image-meta} /></div>
{.end}
{.video?}
{#|video}
{.end}
{.end}
</div>
{.end}
<div class="ProductItem-gallery-thumbnails">
{.if items.1}{.repeated section items}<div class="ProductItem-gallery-thumbnails-item"><img class="ProductItem-gallery-thumbnails-item-image" data-load="false" {#|image-meta} /></div>{.end}{.end}
</div>
</figure>
Associated JS
First off, it should be noted that I went through and console logged every function to see what was giving the Quick View it's functionality - to no avail. Which is subsequently why I'm here. So it's easy to see where the zoom function is originating: the Product View in the Galapagos.ProductItem function on line 103 $imageContainer = Y.one('#jsProductItemImages');
But I don't see anything out of the ordinary pop up when I look at the Quick View. I've got to be missing something!

My Attempts
My first few attempts have been dropping the jsProductItemImages div from the Product view and dumping in the entire figure block from the Quick View then updating the associated css. While it pulls in the images (I can see them in the inspector and they take up space on the page) it shows up as being blank.
I also tried only using the thumbnails section from the Quick View and limiting the Product View to only show the first image by using {.section items.0} but then any thumbnail I clicked wouldn't swap out without writing the script for it (obviously) but I didn't want to write something like that when I know it exists in the code already!
Any help would be greatly appreciated!
UPDATE:
After replacing the product view markup with the quick view markup I ran into these errors
Uncaught TypeError: Cannot read property 'all' of null site.js:104

Unsure why it's hitting an error with .all because it should be addressing the same array of images in both situations?

There's a few questions buried in the this post but let me answer the Quick View question specifically since that's what you're looking to "fix".
Squarespace uses a modular system of JavaScript/CSS add-ons called "rollups". If you pull the source code you'll see a window object that contains the current configuration of any given page. When visiting a Products page, the system triggers the use of their quick view JS and accommodating CSS file. This is where you'll want to be looking. The JS you're digging into is not relevant to Quick View (I don't believe).
Quick View Rollup JS: http://static.squarespace.com/universal/scripts-compressed/product-quick-view-6a1e5642b473ebbb5944-min.js
Quick View Rollup CSS: http://static.squarespace.com/universal/styles-compressed/product-quick-view-eb4b900ac0155bed2f175aa82e2a7c17-min.css
These rollups are triggered off of JavaScript hooks in the template files. What you'll need to do is experiment with using the Galapagos product template word and word so it has the same classes and data-attributes, and see if that works. It would take far too long to cover all of the details of what you need to do without actually working on the project. I would start here first and see if you can setup your product template to triggers the Quick View JS as is, without customization.

Check if my website is open in another tab

I want to check with JavaScript if the user has already opened my website in another tab in their browser.
It seems I cannot do that with pagevisibility...
The only way I see is to use WebSocket based on a session cookie, and check if the client has more than one socket. But by this way, from current tab, I have to ask my server if this user has a tab opened right next to their current browser tab. It is a little far-fetched!
Maybe with localstorage?

The shorter version with localStorage and Storage listener
<script type="text/javascript">
// Broadcast that you're opening a page.
localStorage.openpages = Date.now();
var onLocalStorageEvent = function(e){
if(e.key == "openpages"){
// Listen if anybody else is opening the same page!
localStorage.page_available = Date.now();
}
if(e.key == "page_available"){
alert("One more page already open");
}
};
window.addEventListener('storage', onLocalStorageEvent, false);
</script>
Update:
Works on page crash as well.

Live demo

Using local storage I created a simple demo that should accomplish what your looking to do. Basically, it simply maintains a count of currently opened windows. When the window is closed the unload events fire and remove it from the total window count.
When you first look at it, you may think there's more going on than there really is. Most of it was a shotty attempt to add logic into who was the "main" window, and who should take over as the "main" window as you closed children. (Hence the setTimeout calls to recheck if it should be promoted to a main window) After some head scratching, I decided it would take too much time to implement and was outside the scope of this question. However, if you have two windows open (Main, and Child) and you close the Main, the child will be promoted to a main.
For the most part you should be able to get the general idea of whats going on and use it for your own implementation.
See it all in action here:
http://jsbin.com/mipanuro/1/edit
Oh yeah, to actually see it in action... Open the link in multiple windows. :)
Update:
I've made the necessary changes to have the the local storage maintain the "main" window. As you close tabs child windows can then become promoted to a main window. There are two ways to control the "main" window state through a parameter passed to the constructor of WindowStateManager. This implementation is much nicer than my previous attempt.
JavaScript:
// noprotect
var statusWindow = document.getElementById('status');
(function (win)
{
//Private variables
var _LOCALSTORAGE_KEY = 'WINDOW_VALIDATION';
var RECHECK_WINDOW_DELAY_MS = 100;
var _initialized = false;
var _isMainWindow = false;
var _unloaded = false;
var _windowArray;
var _windowId;
var _isNewWindowPromotedToMain = false;
var _onWindowUpdated;
function WindowStateManager(isNewWindowPromotedToMain, onWindowUpdated)
{
//this.resetWindows();
_onWindowUpdated = onWindowUpdated;
_isNewWindowPromotedToMain = isNewWindowPromotedToMain;
_windowId = Date.now().toString();
bindUnload();
determineWindowState.call(this);
_initialized = true;
_onWindowUpdated.call(this);
}
//Determine the state of the window
//If its a main or child window
function determineWindowState()
{
var self = this;
var _previousState = _isMainWindow;
_windowArray = localStorage.getItem(_LOCALSTORAGE_KEY);
if (_windowArray === null || _windowArray === "NaN")
{
_windowArray = [];
}
else
{
_windowArray = JSON.parse(_windowArray);
}
if (_initialized)
{
//Determine if this window should be promoted
if (_windowArray.length <= 1 ||
(_isNewWindowPromotedToMain ? _windowArray[_windowArray.length - 1] : _windowArray[0]) === _windowId)
{
_isMainWindow = true;
}
else
{
_isMainWindow = false;
}
}
else
{
if (_windowArray.length === 0)
{
_isMainWindow = true;
_windowArray[0] = _windowId;
localStorage.setItem(_LOCALSTORAGE_KEY, JSON.stringify(_windowArray));
}
else
{
_isMainWindow = false;
_windowArray.push(_windowId);
localStorage.setItem(_LOCALSTORAGE_KEY, JSON.stringify(_windowArray));
}
}
//If the window state has been updated invoke callback
if (_previousState !== _isMainWindow)
{
_onWindowUpdated.call(this);
}
//Perform a recheck of the window on a delay
setTimeout(function()
{
determineWindowState.call(self);
}, RECHECK_WINDOW_DELAY_MS);
}
//Remove the window from the global count
function removeWindow()
{
var __windowArray = JSON.parse(localStorage.getItem(_LOCALSTORAGE_KEY));
for (var i = 0, length = __windowArray.length; i < length; i++)
{
if (__windowArray[i] === _windowId)
{
__windowArray.splice(i, 1);
break;
}
}
//Update the local storage with the new array
localStorage.setItem(_LOCALSTORAGE_KEY, JSON.stringify(__windowArray));
}
//Bind unloading events
function bindUnload()
{
win.addEventListener('beforeunload', function ()
{
if (!_unloaded)
{
removeWindow();
}
});
win.addEventListener('unload', function ()
{
if (!_unloaded)
{
removeWindow();
}
});
}
WindowStateManager.prototype.isMainWindow = function ()
{
return _isMainWindow;
};
WindowStateManager.prototype.resetWindows = function ()
{
localStorage.removeItem(_LOCALSTORAGE_KEY);
};
win.WindowStateManager = WindowStateManager;
})(window);
var WindowStateManager = new WindowStateManager(false, windowUpdated);
function windowUpdated()
{
//"this" is a reference to the WindowStateManager
statusWindow.className = (this.isMainWindow() ? 'main' : 'child');
}
//Resets the count in case something goes wrong in code
//WindowStateManager.resetWindows()

(2021) You can use BroadcastChannel to communicate between tabs of the same origin.
For example, put the following at the top level of your js code, then test by opening 2 tabs:
const bc = new BroadcastChannel("my-awesome-site");
bc.onmessage = (event) => {
if (event.data === `Am I the first?`) {
bc.postMessage(`No you're not.`);
alert(`Another tab of this site just got opened`);
}
if (event.data === `No you're not.`) {
alert(`An instance of this site is already running`);
}
};
bc.postMessage(`Am I the first?`);

I know it is late, but maybe help someone
This snippet of code, will detect how many tabs are open and how many are active (visible) and if none of tabs is active, it will choose last opened tab, as active one.
This code will handle windows/tab crash too and it will refresh the count at crash.
Because localStorage is not supported on Stack Overflow currently, please test here.
