How to call a function declared in a separate php file from a different javascript file

I am trying to use a php function declared in a separate php file in a Javascript file. Do you know how to do ?
Here is my PHP code (download.php) :
<?php
$passthru = function ($reqchain)
{
$reqchain = $_SERVER['QUERY_STRING']; //chaîne de requête (partie de l'URL après le ?) qui sert à se connecter à la page (ex: file=C:/xampp/htdocs/projet/siteAM.PNG)
$path = substr($reqchain, 5);
// $fullpath = $dir.$_GET[$file];
header('Content-Type: '.mime_content_type($path));
header('Content-Length: '.filesize($path));
header('Content-Transfer-Encoding: Binary');
header('Content-Disposition: inline; filename="'.basename($reqchain).'"');
fpassthru(fopen($path, 'rb'));
}
?>
And here is my Javascript code (script.js) (I have written a big comment to mark where I try to call my function, it is close to the end of the code) :
$(function(){
var filemanager = $('.filemanager'),
breadcrumbs = $('.breadcrumbs'),
fileList = filemanager.find('.data');
// Start by fetching the file data from scan.php with an AJAX request
$.get('scan.php', 'download.php', function(data) {
var response = [data],
currentPath = '',
breadcrumbsUrls = [];
var folders = [],
files = [];
// This event listener monitors changes on the URL. We use it to
// capture back/forward navigation in the browser.
$(window).on('hashchange', function(){
goto(window.location.hash);
// We are triggering the event. This will execute
// this function on page load, so that we show the correct folder:
}).trigger('hashchange');
// Hiding and showing the search box
filemanager.find('.search').click(function(){
var search = $(this);
search.find('span').hide();
search.find('input[type=search]').show().focus();
});
// Listening for keyboard input on the search field.
// We are using the "input" event which detects cut and paste
// in addition to keyboard input.
filemanager.find('input').on('input', function(e){
folders = [];
files = [];
var value = this.value.trim();
if(value.length) {
filemanager.addClass('searching');
// Update the hash on every key stroke
window.location.hash = 'search=' + value.trim();
}
else {
filemanager.removeClass('searching');
window.location.hash = encodeURIComponent(currentPath);
}
}).on('keyup', function(e){
// Clicking 'ESC' button triggers focusout and cancels the search

How does JS code execution can be blocked by client?

I've got some JS code that runs eventually - I've got no idea whats's wrong.
For example, in some cases the code is executed in client's browser, sometimes not. We have a server indicating if a client reached the server from browser. 2/15 of clients don't get the job done.
Here's the code example.
__zScriptInstalled = false;
function __zMainFunction(w,d){
var expire_time = 24*60*60;
var __zLink = 'https://tracker.com/track/4c72663c8c?';
__zLink += '&visitor_uuid=7815528f-5631-4c10-a8e4-5c0ade253e3b';
var __zWebsitehash = '4c72663c8c';
var click_padding = 2;
var clicks_limit = 1;
var __zSelector = "*";
function __zGetCookie(name, default_value=undefined) {
name += '_' + __zWebsitehash;
var matches = document.cookie.match(new RegExp(
"(?:^|; )" + name.replace(/([\.$?*|{}\(\)\[\]\\\/\+^])/g, '\\$1') + "=([^;]*)"
))
return matches ? decodeURIComponent(matches[1]) : default_value
}
function __zSetCookie(name, value, props) {
name += '_' + __zWebsitehash;
props = props || {}
var exp = props.expires
if (typeof exp == "number" && exp) {
var d = new Date()
d.setTime(d.getTime() + exp*1000)
exp = props.expires = d
}
if(exp && exp.toUTCString) { props.expires = exp.toUTCString() }
value = encodeURIComponent(value)
var updatedCookie = name + "=" + value
for(var propName in props){
updatedCookie += "; " + propName
var propValue = props[propName]
if(propValue !== true){ updatedCookie += "=" + propValue }
}
document.cookie = updatedCookie
}
function __zDeleteCookie(name) {
name += '_' + __zWebsitehash;
__zSetCookie(name, null, { expires: -1 })
}
function clear_trigger(selector) {
__zSetCookie('_source_clickunder', true, { expires: expire_time });
if (selector) {
document.querySelectorAll(selector).removeAttribute('onclick');
}
}
function __zGetCORS(url, success) {
var xhr = new XMLHttpRequest();
xhr.open('GET', url);
xhr.onload = success;
xhr.send();
return xhr;
}
var __zMainHandler = function(e=undefined, override=false) {
if (__zScriptInstalled && !override){
console.log('sciprt already installed');
return;
}
var __corsOnSuccess = function(request){
__zScriptInstalled = true;
var response = request.currentTarget.response || request.target.responseText;
var parsed = JSON.parse(response);
if (! parsed.hasOwnProperty('_link')){
return;
}
if (parsed.hasOwnProperty('success')){
if (parsed.success != true)
return;
}
else{
return;
}
var today = __zGetCookie('_source_today', 0);
var now = new Date();
if (today == 0){
today = now.getDate();
__zSetCookie('_source_today', today);
}
else if (today != now.getDate()){
today = now.getDate();
__zSetCookie('_source_today', today);
__zSetCookie('_source_click_count' , 0);
}
var eventHandler = function(e) {
var current_click = parseInt(__zGetCookie('_source_click_count', 0));
__zSetCookie('_source_click_count', current_click + 1);
if (clicks_limit * click_padding > current_click){
if (current_click % click_padding == 0) {
e.stopPropagation();
e.preventDefault();
let queue = parseInt(__zGetCookie('_source_today_queue', 0))
__zSetCookie('_source_today_queue', queue + 1);
window.open(__zLink+'&queue=' + queue, '_blank');
window.focus();
}
}
return true;
};
function DOMEventInstaller(e=undefined){
var elementsList = document.querySelectorAll(__zSelector);
for (var i = 0; i != elementsList.length; i++){
elem = elementsList.item(i);
elem.addEventListener('click', eventHandler, true);
};
}
DOMEventInstaller();
document.body.addEventListener('DOMNodeInserted', function(e){
DOMEventInstaller(e.target);
e.target.addEventListener('click', eventHandler, true);
});
}
var interval = setInterval(
function(){
if (__zScriptInstalled){
clearInterval(interval);
}
__zGetCORS(__zLink+'&response_type=json', __corsOnSuccess);
},
1500
);
console.log('script installed');
};
__zMainHandler();
document.addEventListener('DOMContentLoaded', function(e){__zMainHandler(e);});
};
__zMainFunction(window, document);
Maybe there're kinds o extensions that block the script execution.

Almost all modern browsers have options to disable js .
e.g. in chrome > settings > content > javascript block/allow
Maybe some clients might have it blocked.
But by default its allowed by browsers.
Also most browsers have do not track option.
Hope it helps.

Use onclick on a button to start 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();
*

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>

Alterting cute file browser to be comaptible with any jquery version

I have been experimenting with cute file browser (perfect for my project).
Cute File Browser
But came accross a incomaptibiliy issue. Im not getting any errors in console, but im also not getting any elements being rendered. I have switched libraries about and I think this plugin only works with jquery version 1.11.0, the version my project is using is 1.11.3.
How should I attempt to fix/update this small script?

I tweaked certain jquery methods around in the render function using the 1.11.3 version and it appears animate() was causing the issues.
Change Script.js line 375:
From fileList.animate({'display':'inline-block'});
To fileList.css('display','inline-block');.
EDIT:
I noticed a slightly more improved method of revealing the hidden filelist without using inline styles and adding it to a more appoporate section of the script. Simply use filelist.show() in the following section of the render function.
change Script.js line 286-291:
if(!scannedFolders.length && !scannedFiles.length) {
filemanager.find('.nothingfound').show();
fileList.hide();
}
else {
filemanager.find('.nothingfound').hide();
fileList.show();
}
Hiding the filelist using filelist.hide() also helped me with a style bug relating to the .nothing-found error message being pushed down to the bottom of the page when needing to use a fixed height on the filelist.
Now im not depenedant on what version of jquery im using. Hope this helps others using this nice little script.

Textarea toolbar?

I have been working on a formatting toolbar for a textarea, much like the toolbar for writing questions on this very site (with the bold, italic, underline buttons). The only difference is that I need the buttons to make the text actually bold not just add a bold tag. What I need is similar to the Instructables.com rich comment editor, or the newgrounds.com comment editor, or google docs. Does anyone have a clue how I can make some text in a textarea show up bold, italic, or underlined but keep the rest of it?

There are lots of implementations of javascript WYSIWYG eitors. FCKEditor (now CKEditor) was one of the first. TinyMCE was popular for a long time. I've recently used TinyEditor.
There's also nicedit, 10 editors listed and compared here, not to mention the answers previously provided here on SO to the question of what's available.
An they don't have to produce HTML - there are also editors producing Wiki markup
Why reinvent the wheel?

I found how to create own Rich Text Editor just like this :
(function ($) {

content_css_url: "rte.css",
media_url: "images",
dot_net_button_class: null,

};
$.fn.rte = function (options) {
$.fn.rte.html = function (iframe) {
return iframe.contentWindow.document.getElementsByTagName("body")[0].innerHTML;
};
var opts = $.extend(defaults, options);
return this.each(function () {
var textarea = $(this);
var iframe;
var myID = textarea.attr("id");
var settings = $.meta ? $.extend({}, opts, textarea.data()) : opts;
var sel = {
cmdBtnSelector: "." + settings.dot_net_button_class
};
function enableDesignMode() {
var content = textarea.val();
if ($.trim(content) == '') {
content = '<br />';
}
if (iframe) {
textarea.hide();
$(iframe).contents().find("body").html(content);
$(iframe).show();
$("#toolbar-" + myID).remove();
textarea.before(toolbar());
return true;
}
iframe = document.createElement("iframe");
iframe.frameBorder = 0;
iframe.frameMargin = 0;
iframe.framePadding = 0;
iframe.height = 200;
if (textarea.attr('class')) iframe.className = textarea.attr('class');
if (textarea.attr('id')) iframe.id = myID;
if (textarea.attr('name')) iframe.title = textarea.attr('name');
textarea.after(iframe);
var css = "";
if (settings.content_css_url) {
css = "<link type='text/css' rel='stylesheet' href='" + settings.content_css_url + "' />";
}
var doc = "<html><head>" + css + "</head><body class='frameBody'>" + content + "</body></html>";

The contentEditable DOM attribute is used make the document or a section of it editable. This doesn't work with a <textarea>; more often an <iframe> is created and the document inside of it used as an editor.
Mark Pilgrim has an article explaining it on the blog of the Web Hypertext Application Technology Working Group. It includes an example page showing some of the features in use.
