How can I trigger modal boxes using the following javascript code?

Hey guys I need just a little bit of help with this.
So I have modal boxes hiding on my page and when I click on them using the video platform VERSE they work perfectly.
My questions is: How can I call the same modal boxes if I wan to call them from a regular link or button on the page.
Here is the sample:
http://digitalfeast.com/clients/nccv/ncc-verse.html
Here is my Javascript code:
(function() {
(function() {
window.onload = function() {
var frame = document.getElementsByName("verse-iframe")[0].contentWindow;
// Variables below (i.e. "menu-1") reference div id from your markup
function receiveMessage(event) {
var data = (typeof event.data === "String") ? JSON.parse(event.data) : event
var modalWindow1 = document.getElementById("ruben-1");
var modalWindow2 = document.getElementById("ruben-2");
var modalWindow3 = document.getElementById("menu-3");
var modalWindow4 = document.getElementById("menu-4");
// Variables below (i.e. "menu-1") reference the unique callback names entered for your hotspots in the Verse editor
if (data.data["identifier"] === "ruben-1") {
modalWindow1.style.display = "block";
}
if (data.data["identifier"] === "ruben-2") {
modalWindow2.style.display = "block";
}
if (data.data["identifier"] === "menu-3") {
modalWindow3.style.display = "block";
}
if (data.data["identifier"] === "menu-4") {
modalWindow4.style.display = "block";
}
}
var closeBtns = document.getElementsByClassName("modal-close");
for (var i = 0; i < closeBtns.length; i++) {
var btn = closeBtns[i];
btn.onclick = function (event) {
event.target.parentNode.parentNode.style.display = "none";
frame.postMessage({action: "play"}, "*");
};
}
window.addEventListener('message', receiveMessage);
var frame = document.getElementsByName("verse-iframe")[0].contentWindow;
};
}());
}());

Given your code, all you need to do is send the window a message using the Messaging API inside your button click handler.
Your event listener will then execute the receiveMessage function and open your model for ruben-1.
window.onload = () => {
document.querySelector('[data-modal="ruben-1"]').addEventListener("click", (e) => {
let postData = {
identifier: e.target.dataset.modal
};
window.postMessage(postData, "*");
});
window.addEventListener('message', m => {
alert(m.data.identifier);
});
}
<button data-modal="ruben-1">Ruben-1 Video</button>

Cannot communicate between captivate html and parent html

I have a published captivate html file that is loaded into an iframe of another html. I cannot communicate between the two, not even with localStorage. Can anyone tell me what I'm missing?
Parent html
var everythingLoaded = setInterval(function () {
if (/loaded|complete/.test(document.readyState)) {
clearInterval(everythingLoaded);
init();
}
}, 10);
function init() {
ScormProcessInitialize();
var studentID = ScormProcessGetValue("cmi.core.student_id");
var student_name = ScormProcessGetValue ("cmi.core.student_name");
var nameArraya = student_name.split(" ");
var nameArrayb = nameArraya[1].split(",");
var studentNumber = nameArrayb[0];
ScormProcessSetValue("cmi.core.lesson_status", "incomplete");
localStorage.setItem("_studentNumber", studentNumber);
alert("Student Number: " + studentNumber + " Student Mame: " + student_name);
setTimeout(function () {
document.getElementById("iFrame_a").innerHTML = "<iframe name='iframe_1' id='frame_1' src='//somepath.com/sandbox/somecourse/index.html' frameborder='0' width='1000px' height='605px'></iframe>";
}, 250);
}
function sendComplete() {
alert("Send from index start!");
ScormProcessSetValue("cmi.core.lesson_status", "completed");
alert("send status: Completed");
}
window.onbeforeunload = function (){
cpInfoCurrentSlide = localStorage.getItem("_cpInfoCurrentSlide")
alert(cpInfoCurrentSlide);
if(cpInfoCurrentSlide >= 40)
{
alert("onbeforeunload called: " + cpInfoCurrentSlide )
ScormProcessSetValue("cmi.core.lesson_status", "completed");
}
}
iframe code snippet
localStorage.setItem("_cpInfoCurrentSlide", cpInfoCurrentSlide);

I believe your problem is with onbeforeunload. As I remember captivate packages clobber any functions associated with onbeforeunload in the parent frame when they load.
Try this instead, override your SCORM api setvalue method:
var oldLMSSetValue = window.API.LMSSetValue;
window.API.LMSSetValue = function(key, value){
if(key === 'cmi.core.lesson_status' && value === 'completed'){
//do your stuff here
cpInfoCurrentSlide = localStorage.getItem("_cpInfoCurrentSlide")
alert(cpInfoCurrentSlide);
}
//call the original scorm api function so that it runs as expected.
oldLMSSetValue(key,value);
};
edit: this code would go in the parent window, not the iframe.

JS script dynamic loading inconsitent

I need help on getting some dynamic js loading working properly. the issue I'm having now is that it is not consistently loading the js script when loading the page. here is the script that I have at the bottom of the page that I'm opening:
function getJSOnload() {
var element;
var parent = document.body;
var cdn = [
LoadFormValidationScript(LoginFormValidator),
LoadFormValidationScript(SetFormLocaleLang)
];
var i = 0, file;
for (i;i<cdn.length;i++) {
file = cdn[i];
element = document.createElement("script");
element.type = "text/javascript";
element.src = file;
parent.appendChild(element);
//free file's value
file = null;
}
};
if (window.addEventListener) {
window.addEventListener("load", getJSOnload(), false);
}
else if (window.attachEvent) {
window.attachEvent("onload", getJSOnload());
}
else window.onload = getJSOnload();
this is the LoadFormValidationScript that i have in an external js file
function LoadFormValidationScript(callback){
function LoadValidationScripts() {
$.getScript('/plugins/script1.min.js', function() {
$.getScript('/plugins/script2.min.js', function() {
$.getScript('/plugins/script3.addons.min.js', function() {
$.getScript('/plugins/script.es_ES.js', function() {
$.getScript('/plugins/script4.fr_FR.js', function() {
$.getScript('/plugins/script5.de_DE.js', callback);
});
});
});
});
});
}
if (!$.fn.formValidation){
LoadValidationScripts();
} else {
if (callback && typeof(callback) === "function") {
callback();
}
}
}
and this is the "setFormLocaleLang" function as an example since it is short one
function SetFormLocaleLang(){
var nberOfForm = document.forms.length; //get number of forms on the page
// if there are no forms in the page don't waist your time
if (nberOfForm > 0) {
var Locale = "en_US"; //default formVlaidation language
//var lang = $('html').attr('lang'); // get the page language
var lang = $("#selectedLanguage").attr('data-lang-id');
// assign the Locale depending on page language
switch (lang) {
case "en" : Locale = 'en_US'; break;
case "fr" : Locale = 'fr_FR'; break;
case "es" : Locale = 'es_ES'; break;
case "de" : Locale = 'de_DE'; break;
default : break;
};
//set the locale for all the forms in the page
for (var i = 0; i < nberOfForm; i++) {
var strFormID = "#" + document.forms[i].id;
$(strFormID).formValidation('setLocale', Locale);
}
}
}
like is said it does work and load the scripts but not all the time, sometimes i have to refresh the page like 3 time for the script to load and sometimes it loads on the first try as soon as i open the page. not sure what is going on and why i get this behaviour.

You're attaching the handlers incorrectly - you're calling getJSOnload() immediately, instead of waiting for document-loaded, as you intend. Reference, don't call, the function:
if (window.addEventListener) {
window.addEventListener("load", getJSOnload, false);
}
else if (window.attachEvent) {
window.attachEvent("onload", getJSOnload);
}
else window.onload = getJSOnload;

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.

Uncaught ReferenceError: X is not defined

This code is being used on a Chrome Extension.
When I call the "showOrHideYT()" function, I get a
"Uncaught ReferenceError: showOrHideYT is not defined | (anonymous
function) | onclick"
This code will search for youtube links in a page, and it will add a button (it's really a div with an event) next to the link to show the iframe with the embedded video, pretty much like Reddit Enhancement Suite. Consider the code, per se, incomplete. I just want to know what am i missing when i call the "showOrHideYT(frameZES12345)" function.
if needed, i can provide manifest.json.
Thanks

});

When you use setAttribute with a string, the event will be executed in the context of the page. The functions which are defined in a Content script are executed in a sandboxed scope. So, you have to pass a function reference, instead of a string:
Replace:
botaoMais.setAttribute('onclick','showOrHideYT(frameZES'+ i +')');
With:
botaoMais.addEventListener('click', (function(i) {
return function() {
showOrHideYT("frameZES"+ i);
};
})(i));
Explanation of code:
(function(i) { ..})(i) is used to preserve the value of i for each event.
Inside this self-invoking function, another function is returned, used as an event listener to click.

I see that you are using jQuery in your code. I personally think if we are using a library like jQuery, then we should not mix the native javascript code and jQuery code.
You can use jQuery bind to bind your the functions you need to call on dom ready.
Read below to know more.
suppose you want to call a javascript function on a button click, Here is the HTML for the same.
<div id="clickme">
<input id= "clickmebutton" type="button" value = "clickme" />
</div>
suppose "test" is the function you need to call, here is the code for test function.
function test() {
alert("hello");
}
you now need to bind the test function on the button click.
$(document).ready(function() {
$("#clickmebutton").bind("click", function(){
// do what ever you want to do here
test();
});
});
