I'm trying to make my own class with panels that open and close content using Bootstrap and jQuery (not an accordion, I want multiple open at a time). However, the click event isn't working for me and I have no idea why... I tried the "*" selector and the alert was working but it's not working when I try to associate it with specific elements.

You should put your jQuery code in document.ready block ensure your code working after those element been generated.
Script.js should be changed like this.
$(document).ready(function(){
$("#demo").click(function(){
alert("hello");
});
});

I am trying to write a short code to capture the signature via a tablet screen on a webpage. However, I can't get the area up that captures that signature.
The code I am using, which I have borrowed from other places that do work is:

I suspect it has something to do with the links to jquery, unless somebody can see something else glaringly obvious. (I am quite new to this)
Is anyone able to put me in the right direction?
Thanks.

There's a couple of things. I've changed the googleapi call to https instead of http. This helps with browsers that are tetchy with mixed content.
The code for the signature is now also at the bottom, so this should make sure the #sig div is there before the code that attaches itself to it is. This is also helped by the document ready function.
Ignore my ../js/ for the signatures. That's just where I put it. See my comment above about viewing page source to see if the file is actually available.
we have been given an assignment to make a div with a background image and couple of titles underneath and when you hover over a title it changes the background picture in the div ("thumbnail"). I am really new to jQuery and have no idea how to approach this. I tried the following code but it is not working.

$('ul a')
.mouseover(function() {

.each(function() {
new Image().src = this.getAttribute('data-image-src');
});
}

I appreciate any help :)
I guess this is the thing you're looking for. Not a tested code. You've missed to say that thumbnail is a class and also it can be a hover event from jquery (check api.jquery for examples)
<script>
$(function() {
$('ul a').hover(function() {
$('.thumbnail img').attr('src', $(this).data('imageSrc'));
});
});
</script>
You can make use hover event : https://api.jquery.com/hover/
See this example as well : https://www.w3schools.com/jquery/tryit.asp?filename=tryjquery_event_hover
I solved it with this code. I wanted to ask though, if there is a possibility to make it animated. When the pictures switch make a fade animation.
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
<script>
$(function() {
$('a').on('mouseover', function() {
var iSrc = $(this).attr('data-image-src');
$('.thumbnail img').attr('src', iSrc);
});
});
</script>
I have a div that serves of container for a css animation that appears over the entire website's home page... a text and background that opens like curtains, revealing the website under it. It's like an intro landing page. The thing is I need it to appear only on first page load. I don't want it to appear on page refresh or if someone navigates thru the site and comes back to home page.
Can someone please show me how I would have to code this because I've search a lot on the web and didn't find any clear explanations for my particular case.
Here is the code for the div:
<div id="landContainer">
<div class="left-half" id="leftP"><article class="leftPanel"><img id="SloganLeft" src="Decouvrez.svg"></article></div>
<div class="right-half" id="RightP"><article class="rightPanel"><img id="SloganRight" src="Atteignez.svg"></article></div>
</div>
So the div I must display only on first page load would be the one with the ID landContainer, that contains a couple of other divs.
Since I'm new to this type of coding, I would need a complete example of the code I need to use with my div.
For Ian... here is the content of my index.html file...

The best way is to use session through which you can determine if its a new request or old.
Server side session will be best here
$( document ).ready(function() {
var isExists = localStorage.getItem("pageloadcount");
if (isExists != 'undefined') { $("#landContainer").hide();
}
localStorage.setItem("pageloadcount", "1");
});
<div id="landContainer">
<div class="left-half" id="leftP">
<article class="leftPanel"><img id="SloganLeft" src="Decouvrez.svg"></article>
</div>
<div class="right-half" id="RightP">
<article class="rightPanel"><img id="SloganRight" src="Atteignez.svg"></article>
</div>
</div>

});
There are two solutions I've used for this in the past.
1) Use an ng-if/ng-show on your img tag. This will prevent the broken image from displaying.
<img ng-if='snapshot'>
2) Set a default image that will load and then be replaced once the other images load.
$scope.snapshot = 'snapshots/default.png';

javascript
$(function() {
$('#span2').click(function() {
$(this).hide(400);
/*$('#span2').hide(400); <--tried this also */
});
});
I've used jquery to animate navigation on a site before. Am i missing something obvious?
Your
$('#span2') // id selector
Should be
$('.span2') // class selector
Since it's a class
Your problem is that you are using the hash # which is the id selector instead of the class selector which is a dot ..
Try
$(function() {
$('.span2').click(function() {
$(this).hide(400);
});
});
You might want to read up more on the different jQuery Selectors on the official documentation
You dont have any elements with ID "span2", they are all CLASS=span2.
Try this:
$(function() {
$('.span2').click(function() {
$(this).hide(400);
});
});
Note: this will effect ALL elements with the class "span2" if you don't want that behavior, then use ID="span2" for a single element, and use unique names for each.
