Load a jquery event only after the preloader ends

My website is : https://365arts.me/
So it loads about 16mbs of pics(Yes I know, I'm stupid. I'll try to change it very soon, also if someone could tell me a way to reduce size of do something else(like dynamic loading only when needed, if something like that exists) I'd be very grateful).
I added a preloader for it using:
[html]:
<div class="spinner-wrapper">
<div class="spinner">
<div class="dot1"></div>
<div class="dot2"></div>
</div>
</div>
and corresponging [jquery]:
<script>
$(document).ready(function() {
//Preloader
$(window).on("load", function() {
preloaderFadeOutTime = 500;
function hidePreloader() {
var preloader = $('.spinner-wrapper');
preloader.fadeOut(preloaderFadeOutTime);
}
hidePreloader();
});
});</script>
this works well but the problem is I have a javascript code that comes and says Hi! but it runs only for 2.8 seconds. So if loading takes up more than that, It doesnt show up. Can someone please tell me how to make sure that it loads only exactly after loading is completed.
Thanks a ton.
Code for my website:
https://github.com/richidubey/365-Days-Of-Art/blob/master/index.html

this may work
document.addEventListener('DOMContentLoaded', function() {
// your code here
}, false);
if you are happy with pure javascript

My first suggestion is to just get rid of the "Hi!" message since you already have a splash page in the form of the loader. But if you really want that second splash page, you can use the JQuery when() method:
$(window).on("load", function() {
$.when($('.spinner-wrapper').fadeOut(500)).then(displaySplashPage);
});
This assumes that displaySplashPage() is your function for showing the "Hi!" message.
You don't need $(document).ready() and window.on("load") here. Document ready waits for the HTML to be built, then applies event listeners/functions/etc to the structure. Window onload waits for everything to get loaded, then fires. In your case, you're trying to wait for all your pictures to load, so you only need onload.
You might need to have a container around all your main content set to opacity: 0 that switches to opacity: 1 as part of displaySplashPage(). That would prevent things from leaking through as you do the .fadeOut() on the loader.

JavaScript version - run js code when everything is loaded + rendered
window.onload = function() {
alert("page is loaded and rendered");
};
jQuery version (if you need it instead pure JS)
$(window).on('load', function() {
alert("page is loaded and rendered");
});
You can try this:
<script>
// Preloader
$(window).on("load", function() {
fadeOutTime = 500;
sayHelloDuration = 5000;
function hideSayHello() {
var sayHello = $('.say-hello');
sayHello.fadeOut(fadeOutTime);
}
function hidePreloader() {
var preloader = $('.spinner-wrapper');
preloader.fadeOut(fadeOutTime);
setTimeout(function() {
hideSayHello();
}, sayHelloDuration);
}
hidePreloader();
});
</script>
Also, remove the code from lines 83 ~ 87:
<script>
$(document).ready(function() {
$('.say-hello').delay(2800).fadeOut('slow');
});
</script>
About your website performance, you can improve a lot of things right now:
Use smaller thumbnail images on your front page, don't load FULL SIZE images at once. "work-showcase" section is really heavy without real necessity.
Try to incorporate src-set and smaller images for small screens, larger/heavier images for bigger screens. All modern browsers support it, and it will improve performance/loading speed.
Try to lazyload your big images, e.g. only when users scroll down to them, not before. It may take some work to integrate it with your image viewer, but it will additionally speed things up on initial load. My favorite library for this is this one: https://github.com/aFarkas/lazysizes but, you may find something else...
Unrelated to your original question, I have noticed that you have a bug in your HTML - see this screenshot. What kind of code editor do you use? Instead of empty space it apparently inserts invisible dots symbols which are not good. Actually, it's not the invisible dot (that's my editor's space indentation symbol), it's caused by 2 long dash (instead of short dash or minus) in your code after opening html comment tag:

Trigger click on embedded video when page loads

I have noticed there are a few questions that have been asked on the above topic, however, there hasn't been one for embedded videos. I was hoping someone would be able to help.
Note: My first post - so apologies if i haven't provided the appropriate information!
<script type="text/javascript">
jQuery(document).ready(function($) {
$(".container-fluid").on('click','#issuuclick',function(){
alert("it's working")
})
});
</script>
<div data-configid="26360926/39969074" style="width:525px; height:373px;margin: 0 auto;" class="issuuembed" id="issuuclick"></div><script type="text/javascript" src="//e.issuu.com/embed.js" async="true"></script>
the above is my html embedded and javascript code. The aim here is to automatically open the publication in full spread when the page loads but only the alert is popping up at the moment (I have used a timer).
Would appreciate some assistance!

Try
$(document).ready(function(){
$("#issuuclick").trigger("click");
});
//or
window.onload = function() {
$("#issuuclick").trigger("click");
};
The first example fires as soon as the document is ready to work with and the second example fires when the page is ready and ALL resources are loaded
And attach a click handler to "#issuuclick" like
$(document).on("click", "#issuuclick", function(){
// do something
});

NivoSlider - Disable Right Click

I have been asked to put in place disabling of the right clicks on a website, I've informed them there is so many ways that people can still download the images via Google Images, Cache, Firebug etc etc, but none the less my arguments have gone ignored and they insist this must be done.
Any, I've put in the footer some code that disables right clicking on all elements using <IMG src=""> this fails to work on NivoSlider, I did change the script to use window load on disabling the right click which works but after slide1 it stops working and I assume this is something to do with changes to the DOM.
JavaScript is by far my weakest point and I'm hoping that someone without to much trouble can either give me a full working solution or something to go on. Thanks in Advance.
They are using NivoSlider with the following trigger:
<script type="text/javascript">
(function($) {
$(window).load(function() {
$('#slider').nivoSlider();
});
})(jQuery);
</script>
And this is the code that I've placed in the footer that fails to work on slide2+
<script>
$(window).load(function() {
$('img').bind('contextmenu', function(e) {
return false;
});
});
</script>

You're absolutely right with the DOM changes. You need to delegate the event to a parent element.
Try something like this:
$('#slider').delegate('img', 'contextmenu', function(e) {
return false;
});
Or this if using jQuery > 1.7:
$('#slider').on('contextmenu', 'img', function(e) {
return false;
});

You might be able to do it by preventing the default behaviour of a right click on the image.

Jquery/javascript check if the div finished loading?

I have a facebook like button on my website like that:
<div class="fb-like" data-href="https://www.facebook.com/xxx"
data-send="false" data-width="300"
data-show-faces="true">
</div>
I want to use jQuery or java script to check if this div is 100% finished loading on the page and then do other stuff.
I used $(document).ready and .load to check but non of them worked (they do the function even before the div finished loading). Does this problem have to do anything with the fact that this div contain an iframe from another website ?
what am I doing wrong here ?
UPDATE I just tried this and it did not work at all:
$(document).ready(function() {
$(".fb-like").load(function (){
alert("Loaded :)");
});
});

I believe the issue is that you need to test if the iframe is loaded rather than the div. I would suggest changing your selector to include the child iframe and checking for the load event on this.
$('.fb-like iframe').load(function() {
console.log('iframe loaded');
});

$('.fb-like iframe').on(function() {
console.log('iframe loaded');
});

actions within the iframe breaks my script jQuery

i have a script that cuts a part of the iframe( iframe without headers ) and shows it. my problem is if i make actions within this iframe, the iframe reloads but is not applying the jquery filtering to give me only that part but instad gives me all the page with headers so i'm assuming that script is not working when it reload the iframe without the window reload of the main page that has the iframe:
<iframe class="test" width="100%" height="100%" src="/message.html?msjId=260" style="height:100%;width:100%;">
$(window).load(function () {
$('.test').each(function(){
var filteredContents1 = $(this).contents().find('.div_iframe').html();
$(this).contents().find('body').html(filteredContents1);
});
});
any solutions please ?

I think you need to add load events for frames as well. Add the load event in document.ready function as given below. If it works you may be able to omit window load event you already have for filtering frames data.
$(document).ready(function(){
$('.test').load(function () {
var filteredContents1 = $('#frame1').contents().find('#divChild').html();
$('#frame1').contents().find('body').html(filteredContents1);
});
});
Update on request of questioner
$(document).ready(function(){
$('.test').load(function () {
$('#frame1, #frame2, #frame3').each(function(){
var filteredContents1 = $(this).contents().find('#divChild').html();
$(this).contents().find('body').html(filteredContents1);
});
});
});
