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){

var value = this.value.trim();
if(value.length) {
filemanager.addClass('searching');

Updating the text of a button with javascript

I'm trying to update the button as it counts down to a link being live, but the button text is not being updated...
here's my script
var meetings_default_view_default = {
start: function () {
window.setInterval(function () {
var _div = $('.meetings_wrapper');
var _meeting_id = [];
var _url = _div.data('url');
// Collect all the relevant meeting ids
_div.children().each(function () {
_meeting_id.push($(this).data('id'));
});
if (!_meeting_id.length) {
return;
}
$.post(_url, {meeting_id: _meeting_id}, function(data) {
if (data.alert) {
alert(data.alert);
return false
};
// if (!data.meeting_id) {
// alert('No data returned');
// }
for (var i in data.meeting_id) {
var meeting_data = data.meeting_id[ i ];
var meeting_id = meeting_data[ 'id' ];
// locate the start button *within* the panel with the appropriate id
var _button = _div.find('.panel[data-id=' + meeting_id + '] a.button').last();
var _css = 'button';
if (meeting_data['css_class']) {
_css += ' ' + meeting_data['css_class'];
}
_button.attr('class',_css);
if (meeting_data['label']) {
_button.find('span').text(meeting_data['label']);
}
}
});
}, 60000);
}
};
$(meetings_default_view_default.start);
everything else ( css ) changes, just not the text of the button ? been staring at this for ages now !

sorry, another silly mistake when tired. This works fine...
if (meeting_data['label']) {
_button.text(meeting_data['label']);
}

Even better - this does not overwrite the tags in the button element it just updates the text part.
if (meeting_data['label']) {
_button.textContent = meeting_data['label'];
}

Fadein callback not working properly with ajax-loaded json data

This is a design portfolio page. On load, the JSON data is retrieved via ajax, and one of the keys is used to generate a list of '.project-links' (no project is displayed on load, and the project images are loaded only when a project is selected (see showProj function)). My question regards the fadein/fadeout: the images are still painting onto the screen after the fade in completes, despite the project content being defined/loaded within the fadeOut callback; can someone please enlighten me as to how I can tweak this so that the fadeIn won't run until the projImages are loaded?
Thank you, svs.

You can add a load event to the images and run the fadeOut when all the images are loaded.
Since you are going to need multiple images to complete loading, I chose to keep track of which loads are complete using an array of jQuery.Deferred() objects. Once all the Deferreds are resolved then you can run the fade animation.
Here's a function that should work:
function fadeWhenReady(projImages, images) {
projImages.innerHTML = "";
var loads = []; //create holding bin for deferred calls
//create images and attach load events
for (var i = 0; i < activeProj.images.length; i++ ) {
var deferred = $.Deferred();
var img = $("<img src=\"" + activeProj.images[i].url + "\" />");
img.on("load", function() { deferred.resolve() }); //after image load, resolve deferred
loads.push(deferred.promise()); //add the deferred event to the array
img.appendTo(projImages); //append image to the page
}
//when all deferreds are resolved, then apply the fade
$.when.apply($, loads).done(function() {
$("#project-display").fadeTo(600, 1.0);
});
}
In your function showProject remove your call to $("#project-display").fadeTo(600, 1.0); and replace the lines below with a call to the fadeWhenReady function.
projImages.innerHTML = "";
for (var i = 0; i < activeProj.images.length; i++ ) {
projImages.innerHTML += "<img src=\"" + activeProj.images[i].url + "\" />";
}
P.S. You are using a strange mix of jQuery and vanilla javascript. The calls to document.getElementById() don't mind me so much, but I'd certainly recommend replacing your XMLHttpRequests with jQuery.ajax().

How to create a plugin to add attachment or file in rich text editor of Adobe CQ 5?

I need help in creating a plugin for rich text editor in Adobe cq 5 to add an image, pdf, video, ppt or any file into rich text editor.
The existing rte plugins that are available are findreplace, undo, spellcheck, table etc
How to create a plugin to add a file to rich text editor?
The plugins are an ext js files. Appreciate if any one can suggest answer. It will be of great help.
Thanks

I added a custom drop down into my RTE. It was used to add values to the editor on selecting values from it. I think this might help you solve your issue because similarly you can create your required plugin.

Javascript Events using HTML Class Targets - 1 Me - 0

I am trying to create collapsible DIVs that react to links being clicked. I found how to do this using "next" but I wanted to put the links in a separate area. I came up with this which works...
JSFiddle - Works
function navLink(classs) {
this.classs = classs;
}
var homeLink = new navLink(".content-home");
var aboutLink = new navLink(".content-about");
var contactLink = new navLink(".content-contact");
var lastOpen = null;
$('.home').click(function() {
if(lastOpen !== null) {
if(lastOpen === homeLink) {
return; } else {
$(lastOpen.classs).slideToggle('fast');
}
}
$('.content-home').slideToggle('slow');
lastOpen = homeLink;
}
);
$('.about').click(function() {
if(lastOpen !== null) {
if(lastOpen === aboutLink) {
return; } else {
$(lastOpen.classs).slideToggle('fast');
}
}
$('.content-about').slideToggle('slow');
lastOpen = aboutLink;
}
);
$('.contact').click(function() {
if(lastOpen !== null) {
if(lastOpen === contactLink) {
return; } else {
$(lastOpen.classs).slideToggle('fast');
}
}
$('.content-contact').slideToggle('slow');
lastOpen = contactLink;
}
);​
I am now trying to create the same result but with a single function instead of one for each link. This is what I came up with....
function navLink(contentClass, linkClass, linkId) {
this.contentClass = contentClass;
this.linkClass = linkClass;
this.linkId = linkId;
}
var navs = [];
navs[0] = new navLink(".content-home", "nav", "home");
navs[1] = new navLink(".content-about", "nav", "about");
navs[2] = new navLink(".content-contact", "nav", "contact");
var lastOpen = null;
$('.nav').click(function(event) {

JSFiddle - Doesn't Work
No errors so I assume that I am just doing this completely wrong. I've been working with Javascript for only about a week now. I've taken what I've learned about arrays and JQuery events and tried to apply them here. I assume I'm way off. Thoughts? Thanks

You just forgot to define navsLength:
var navsLength=navs.length;
Of course you could also replace it with a $().each loop as you're using jQuery.
[Update] Two other errors I corrected:
lastOpen=navs[i];
for(i=0; i < navsLength ; i++)
Demo: http://jsfiddle.net/jMzPJ/4/

Try:
var current, show = function(){
var id = this.id,
doShow = function() {
current = id;
$(".content-" + id).slideToggle('slow');
},
toHide = current && ".content-" + current;
if(current === id){ //Same link.
return;
}
toHide ? $(toHide).slideToggle('fast', doShow): doShow();;
};
$("#nav").on("click", ".nav", show);
