Use onclick on a button to start javascript - javascript

Hi there I'm pretty new to using functions and onclick actions to call javascript so I could do with some help. Basically, I've installed a plugin on WordPress which adds a button to the page in the form of a widget and once clicked it starts a script. However, I don't like their button so I'm trying to code my own but I want it to start the script like there's.
Here's the script code:
/*
* Timely BookButton plugin
* Example usage:
* var button = new timelyButton('doedayspa');
*
* Booking process can be kicked off manually by calling the start method on the button instance e.g.
* button.start();
*
*/
// Need this for legacy support of older versions of the BookingButton
var timelyButton;

So how can I run this javascript when I click the button?
Any help would be greatly appreciated!

You could create a script tag automatically if the button has been clicked.
document.getElementById('myButton').addEventListener('click', () => {
const script = document.createElement("script");
script.src = 'my-other-file.js';
document.head.appendChild(script);
})
<button id="myButton">Load JS File</button>

I load it in this way in functions.php in Wordpress:
function wpb_hook_javascript() {
?>
<script defer type="text/javascript" id="cookiebanner" src="https://www.examplesite123.com/cookiebar.js"></script>
<?php
}
add_action('wp_head', 'wpb_hook_javascript');
It works fine.
Now i duplicate the same javascript code and i called it stickybar.js. I add some modifications, also change class with name "stickybar":
The code of the stickybar.js is here (i pasted it in jsfiddle because there is too much text for stackoverflow)
Then i show this second bar (stickybar.js) only on mobile device and after 8 second with this CSS:
.stickybar { display: none; }
#media only screen and (max-device-width:480px) {
.stickybar {
display: block;
animation: cssAnimation 0s 8s forwards;
visibility: hidden;
}
#keyframes cssAnimation {
to { visibility: visible; }
}
}
I load it in Wordpress with this code in functions.php:
function wpb_hook_javascript() {
?>
<script defer type="text/javascript" id="cookiebanner" src="https://www.examplesite123.com/stickybar.js"></script>
<?php
}
add_action('wp_head', 'wpb_hook_javascript');
It works fine.
If i load one by one of this codes, they work fine.
The problem is that when i load the two scripts together in this way in functions.php, only the first works:
function wpb_hook_javascript() {
?>
<script defer type="text/javascript" id="cookiebanner" src="https://www.examplesite123.com/cookiebar.js"></script>
<script defer type="text/javascript" id="cookiebanner" src="https://www.examplesite123.com/stickybar.js"></script>
<?php
}
add_action('wp_head', 'wpb_hook_javascript');
How can i load the two scripts together?
The comment thread on this question is semantically correct, you can only have one instance of each html id attribute, they must be unique, and your find_script_by_id methods are both searching for the same thing.
However, you're doing what's generally called "baking in" the scripts into your header which is at best, a faux pas, at least as far as WordPress is concerned. Properly Enqueueing Scripts (and styles) is very easy in WordPress, and your future self, web clients, and other people who look at your code will thank you for doing it.
It's not unlike how you're "baking in" the scripts now:
function wpb_hook_javascript() {
?>
<script defer type="text/javascript" id="cookiebanner" src="https://www.examplesite123.com/cookiebar.js"></script>
<script defer type="text/javascript" id="cookiebanner" src="https://www.examplesite123.com/stickybar.js"></script>
<?php
}
add_action('wp_head', 'wpb_hook_javascript');
But with a few things changed:
function enqueue_my_scripts(){
wp_enqueue_script( 'cookie-bar', 'https://www.examplesite123.com/cookiebar.js', array(), '1.0', true );
wp_enqueue_script( 'sticky-bar', 'https://www.examplesite123.com/stickybar.js', array(), '1.0', true );
}
add_action( 'wp_enqueue_scripts', 'enqueue_my_scripts' );
Namely, it uses the wp_enqueue_script() function on the wp_enqueue_scripts hook. This lets you defer the script to the footer, load in the header, add version numbers to prevent caching issues, add dependencies, allows you to dynamically add/remove them programatically,gives them unique ID's based on the handle, and much more. (You do still need to update your find_script_by_id functions to use these new handles instead cookie-bar, sticky-bar, change the global_instance_name, etc. (more on that in a second)
With that said, if the .js files are on your server, you'll want to use site_url(), plugins_url(), get_stylesheet_directory_uri(), or similar functions to grab the URL of the file instead of typing it out. If you're using a remote resource, don't worry about it, but if they're on you're site, you should swap out the baked in version for that so you don't have issues if you ever move your site, and it allows you easier methods to edit the version to prevent caching problems if you change them.
Back to your variables, you may also want to replace your find_script_by_id type functions with document.currentScript instead, to allow them to be more abstract and not rely on typo/duplicate prone element IDs, and instead reference the currently running <script> tag.

js for newest chat message order

in my chat extension for phpBB, i use ajax for the js with a little jquery mixed in. i'm setting it up for users to select if they want the newest messages at the top or the bottom in accordance to their setting in their user control panel. the php side of it is done and works well but the js is still adding the new message at the top, ignoring the sort order in the php.
in the php. note that the sort order is set with this line
ORDER BY c.message_id ' . ($this->user->data['user_ajax_chat_messages_down'] ? 'DESC' : 'ASC');
i can't post the php in this post as the body is limited to 30000 characters. so i will post it if needed.
here is the js that does all the work

what needs to be changed to accomplish what i'm trying to do? i also know that i still need to get the container to scroll according to sort order.
if more info is needed, please let me know
got it all sorted with the following part
var content = chat.innerHTML;
chat.innerHTML = isDown ? (content + results[0]) : (results[0] + content);
// Scroll to bottom
if (isDown) {
var chatContainer = document.querySelector('.shout-body');
chatContainer.scrollTop = chatContainer.scrollHeight;
}```

Open totally new window when clicking on screen

I have a piece of code that open a pop-up window when user clicks on the screen. The problem is, if you click again, it will not open another pop-up, it will just "reload" the already opened window. There is a way to create another with second click on screen?

You seem to run the 'open' command with the name attribute set. This creates a reference of that name to the window, when you then run that command again with the same window it will use the window that already has that reference. The solution would be to run open without name:
open(url, '', ...)
Here is some documentation on open

Popunder script that works on all mobiles

I have tested around 15 different popunder scripts to find one that works on all mobiles. The following script is the best one I've found and works perfectly on my Galaxy S3 but annoyingly pops-over on a Galaxy S5. I need the script to popunder on any action on the screen, so that it opens in the background without interfering with the current page. This script has everything I need aside from the fact it behaves differently depending on what Android device it's run on. Can anyone please assist in editing this JavaScript code so it pops-under on all Android browsers and not just some?
Here is the code:

How to select all images in the page?

I have this jQuery-script that gives any image or object with tag data-retina="true" a retina-resolution-image or background-image.
But how do I remove the last part from the script so that this function will apply on every image, not just the one with the data-retina tag?
(function($) {
"use strict";
var retinaReplace = function(element, options) {
this.options = options;
var $el = $(element);
var is_image = $el.is('img');
var normal_url = is_image ? $el.attr('src') : $el.backgroundImageUrl();
var retina_url = this.options.generateUrl($el, normal_url);
$('<img/>').attr('src', retina_url).load(function() {
if (is_image) {
$el.attr('src', $(this).attr('src'));
} else {
$el.backgroundImageUrl($(this).attr('src'));
$el.backgroundSize($(this)[0].width, $(this)[0].height);
}
$el.attr('data-retina', 'complete');
});
}
retinaReplace.prototype = {
constructor: retinaReplace
}
$.fn.retinaReplace = function(option) {
if (getDevicePixelRatio() <= 1) { return this; }
return this.each(function() {
var $this = $(this);
var data = $this.data('retinaReplace');
var options = $.extend({}, $.fn.retinaReplace.defaults, $this.data(), typeof option == 'object' && option);
if (!data) { $this.data('retinaReplace', (data = new retinaReplace(this, options))); }
if (typeof option == 'string') { data[option](); }
});
}
$.fn.retinaReplace.defaults = {
suffix: '-x2',
generateUrl: function(element, url) {
var dot_index = url.lastIndexOf('.');
var extension = url.substr(dot_index + 1);
var file = url.substr(0, dot_index);
return file + this.suffix + '.' + extension;
}
}
$.fn.retinaReplace.Constructor = retinaReplace;
var getDevicePixelRatio = function() {
if (window.devicePixelRatio === undefined) { return 1; }
return window.devicePixelRatio;
}
$.fn.backgroundImageUrl = function(url) {
return url ? this.each(function () {
$(this).css("background-image", 'url("' + url + '")')
}) : $(this).css("background-image").replace(/url\(|\)|"|'/g, "");
}
$.fn.backgroundSize = function(retinaWidth, retinaHeight) {
var sizeValue = Math.floor(retinaWidth/2) + 'px ' + Math.floor(retinaHeight/2) + 'px';
$(this).css("background-size", sizeValue);
$(this).css("-webkit-background-size", sizeValue);
}
$(function(){
$("[data-retina='true']").retinaReplace();
});
})(window.jQuery);
how do I remove the last part from the script so that this function will apply on every image, not just the once with the data-retina-tag?
Change:
$(function(){
$("[data-retina='true']").retinaReplace();
});
To:
$(function(){
$("img").retinaReplace();
});
