Function removes items from localStorage only if run manually

I'm looking for advice/tips on how to fix a function that is supposed to remove items from localStorage. I'm following a tutorial by John Smilga that I found on Youtube. Although I've modeled my code on his, apparently, I have missed something.
This function works perfectly well if I run it manually from the console and pass in the id of the item that I want to remove from localStorage.
function removeFromLocalStorage(id) {
console.log(id);
let storageItems = getLocalStorage();
console.log(storageItems);
storageItems = storageItems.filter(function(singleItem) {
if (singleItem.id !== id) {
return singleItem;
}
})
console.log(storageItems);
localStorage.setItem("list", JSON.stringify(storageItems));
}
However, when this function is triggered by the deleteItem() function, it refuses to remove the item from localStorage. It still works, there are a bunch of console.logs in it that track its execution, and I can check that it receives the correct item id as the argument, but for some reason it doesn't filter out the item that needs to be removed. I am completely lost and have no idea how to identify the problem. I can't debug it with console.logs as I usually do. I will be very grateful if you help me find the problem. Any advice will be appreciated.
In case the entire code is needed, please find it below.

Your code is fine you just used the wrong comparison operator.
In your case you are comparing 2 IDs (operands) to see if they match up, so you should use normal operators such as (==, !=), but instead in your case, you have used strict operators which are used to compare the operand type and the operand itself.
You can learn more about Comparison Operators here.
Ultimatly,
In your function removeFromLocalStorage(id), you have an extra equal sign in your if function.
Instead of:
if (singleItem.id !== id) {
return singleItem;}
It should be:
if (singleItem.id != id) {
return singleItem;}
Hope this helps.

Get selected value from div dropdown

I have a dropdown from which I want to find the selected value.
The dropdown is basically a big blue button which, when pressed, shows different customers:
When an option is clicked, the value changes to the selected customer.
What I want to do is access this value somewhere else in my HTML script.
var Klanten = [

'ING',
'NNPC',
'Meewind',

For this i used the method [http://www.xpertdeveloper.com/2012/10/webpage-screenshot-with-html5-js/] , here screenshot is generated but without style also it is not downloading . Please help , is there any jQuery library available for this?

You can achieve this using the following JavaScript libraries ...
html2canvas ( for taking screenshot of webpage )
FileSave.js ( for downloading the screenshot as an image )

I found that dom-to-image did a much better job than html2canvas. See the following question & answer: https://stackoverflow.com/a/32776834/207981
If you're looking to download the image(s) you'll want to combine it with FileSaver.js (already mentioned here), and if you want to download a zip with multiple image files all generated client-side take a look at jszip.

Few options for this
either use this
<html>
<head>
<title> Download-Button </title>
</head>
<body>
<p> Click the image ! You can download! </p>
<a download="logo.png" href="http://localhost/folder/img/logo.png" title="Logo title">
<img alt="logo" src="http://localhost/folder/img/logo.png">
</a>
</body>
</html>
or You can use Mordernizr
or maybe this works
<a href="/path/to/image" download>
<img src="/path/to/image" />
</a>
refer to this link aswell

Html into wordpress theme

I need to make a fixed bottom footer to my WordPress web, with some buttons including js with a popover. I've Pillar Theme and I only need to make this change. I need to put it into my footer.php. But when I try, nothing works. I do not know if this is the best way to do that. Here is the code that I do for the footer:

You can try Sticky footer with jQuery. Add this code in your js file.
var $ = jQuery.noConflict();
jQuery(document).ready(function($){
/* sticky footer function */
StickyFooter()
});
/* Script on resize */
jQuery(window).resize(function($) {
/* sticky footer function */
StickyFooter();
});
/* Script on load
----------------------------------*/
jQuery(window).load(function($) {
/* sticky footer function */
StickyFooter();
});
/* Sticky Footer Function */
function StickyFooter(){
var Stickyfooter = jQuery( 'footer' ).outerHeight()
jQuery('#wrapper').css('margin-bottom',-Stickyfooter) /* Here #wrapper is your main <div> of <body> */
jQuery('#wrapper').css('padding-bottom',Stickyfooter)
}

Javascript Slideshow Functions Not Working

I would please like an explanation to why the slideshow is not working. Below I have used an interval to perpetually change the slideshow, if userClick is false. The white and squared buttons (made of divs) are set to call upon two functions; slideRight() or slideLeft() and clicked(). When the buttons are clicked however, the clicked() function does not seem to change the variable, based on the data on top of the page.
<body>
<div class="page-wrapper">
<header>
<div class="headContent">
<h1 class="titleText">Slideshow</h1>
<h2 class="subTitleText">A slideshow made with JavaScript.</h2>
<p>userClick <span id="uc"></span></p>
</div>
<nav>
<ul>
<li>Home</li>
<li>About</li>
<li>Gallery</li>
</ul>
</nav>
</header>
<div class="body-wrapper">
<h1 class="titleText">Slideshow</h1>
<div id="slideshow">
<div id="leftSlide" onclick="leftSlide(); clicked()"></div>
<div id="rightSlide" onclick="rightSlide(); clicked()"></div>
</div>
<p>The image is not invoked by a tag, but invoked by the background property using Javascript.</p>

var slideTo = 1;

slideTo = slideTo - 1;

CSS coding below.

Try changing the checking part to:
window.onload = function() {
setInterval(function () {
document.getElementById("uc").innerHTML = userClick;
}, 100);
}
The first argument of setInterval has to be a function (something that can be called), not a generic piece of code.
