JS Function Not Defined Chrome Extension Popup.js

I am trying to add this button On Codepen to my chrome extension, my HTML and CSS work perfectly fine. The JS is popup.js and is on the same level as the rest of the code, but it doesn't seem to be linked to the popup.html. Manifest is in the image . I did convert the SCSS to CSS using an online converter. I need help linking the js to popup.html so the button works as it does in Codepen.
Html, CSS & JS:
$('button.cooldown').click(function(){
var btn = $(this);
btn.prop('disabled', true);
setTimeout(function(){
btn.prop('disabled', false);
},15000);
});

How to reset a placeholder whenever you exit a search box event?

I've got an overlay search box (check code). The search box got a placeholder "Sök", let's say the user writes something in the textbox but then exits (presses the x in the right upper corner). Then I want the text that the user wrote to be removed and the placeholder reset, so whenever the user enters the search box again the text is removed and the placeholder is back. How do I create this event?

If you set the value of the input back to nothing when the closing button is clicked, the placeholder should appear again:
const button = document.querySelector( 'button' );
const input = document.querySelector( 'input' );
button.addEventListener( 'click', event => {
input.value = '';
});
<input type="text" placeholder="Sok">
<button>Close</button>

Try with setValue('') method to reset any element value.

How can I create modal popup effect, If I'm using separate html/css pages?

I want to create a Modal Popup effect every time I click on "Login" on my index page.
The only thing is, I have created separate HTML/CSS pages (for example, index.html/css, login.html/css, etc..).
I'm confused, how to use JavaScript to make this happen.
As I have separate pages. I know how to apply modal popup effect, on single html/css page using JavaScript.
But I don't know how to make this happen if I'm using several different pages. My code looks messed up a bit. All my pages are linked to each other properly but without any effect.
Below is my index.html code and login.html code along with the css code.

JS code for modal on single HTML page:-
// GetElements
const modal = document.querySelector('#modal');
const modal_btn = document.querySelector('#modal-btn');
const close_btn = document.querySelector('.close');
//Event_Listener
modal_Btn.addEventListener('click', openModal);
close_Btn.addEventListener('click', closeModal);
window.addEventListener('click', outsideClick);
//Open & Close
function openModal() {
modal.style.display = 'block';
}
function closeModal() {
modal.style.display = 'none';
}

If I'm understand correctly, you are trying to use a separate HTML file as a modal, right? If that correct, try to watch this answer :
Open Modal (bootstrap) from other html-file

GetAjax gets the remote file and load_modal is just a shorthand function that calls getajax and loads the modal.
function getAjax(url, success) {
var xhr = window.XMLHttpRequest ? new XMLHttpRequest() : new ActiveXObject('Microsoft.XMLHTTP');
xhr.open('GET', url);
xhr.onreadystatechange = function() {
if (xhr.readyState>3 && xhr.status==200) success(xhr.responseText);
};
xhr.setRequestHeader('X-Requested-With', 'XMLHttpRequest');
xhr.send();
return xhr;
}
function load_modal(url){
getAjax(url, function(data){
modal.innerHTML = data;
modal.style.display = 'block';
});
}

Unless you have a very good reason for doing so, don't use and . Seems unnecessary and convoluted.
It's quite simple to grab the value from an <input> or <textarea> with JavaScript and place it in another element, like a <div>. Here's an uber basic example that would produce a live example (pretend that the green DIV is a photo of a t-shirt).
var $text = $( '.tshirt-text' );
var $demoText = $( '.demo-tshirt-text' );
$text.on( 'keyup', function ( e ) {
$demoText.text( $text.val() );
} );
.demo-tshirt {
position: relative;
width: 300px;
height: 400px;
background-color: seagreen;
}
.demo-tshirt-text {
position: absolute;
top: 30%;
left: 50%;
width: 50%;
transform: translateX( -50%);
color: white;
font-family: Arial, sans-serif;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<label for="tshirt-text">
Text: <input type="text" id="tshirt-text" class="tshirt-text" name="tshirt-text">
</label>
<div class="demo-tshirt">
<div class="demo-tshirt-text"></div>
</div>

If the entire content of your iframe is just the background definition, you could write the HTML to the iframe document directly.
from Write elements into a child iframe using Javascript or jQuery ...
var ifrm = document.getElementById('myIframe');
ifrm = ifrm.contentWindow
|| ifrm.contentDocument.document
|| ifrm.contentDocument;
ifrm.document.open();
ifrm.document.write('Hello World!');
ifrm.document.close();

Anchors apply just for simple navigation around the page, for changing tabs etc. you need to add some extra code, something like:
(function($) {
// constants
var SHOW_CLASS = 'show',
HIDE_CLASS = 'hide',
ACTIVE_CLASS = 'active';
switchTab = function(href){
var $link = $('a[href=' + href + ']'),
$tab = $(href);
$('.active').removeClass(ACTIVE_CLASS);
$link.addClass(ACTIVE_CLASS);
$('.show')
.removeClass(SHOW_CLASS)
.addClass(HIDE_CLASS)
.hide();
$($tab)
.removeClass(HIDE_CLASS)
.addClass(SHOW_CLASS)
.hide()
.fadeIn(550);
}
$('.tabs').on('click', 'li a', function(e) {
e.preventDefault();
switchTab($(this).attr('href'));
});
if(window.location.hash){
switchTab(window.location.hash);
}
})(jQuery);
