How to enable touch events on pjax library?

I am developing a site where I use Pjax library (a port of jquery pjax). However the touch events don't go through. I am using Pjax like so:
var pjax = new Pjax({ selectors: ["head title", "body"] })
and also have some animations:
document.addEventListener('pjax:send', function(){
var $main = document.querySelector('main')
$main.style.opacity = 0
})
document.addEventListener('pjax:complete', function(){
var $main = document.querySelector('main')
$main.style.visibility = 'hidden'
$main.style.opacity = 0
setTimeout(function(){
document.querySelector('main').style.visibility = 'visible'
document.querySelector('main').style.opacity = 1
attach_menu_control()
}, 10)
})
I need it to work on mobile. The site is www.saulesinterjerai.lt (can be buggy)

I found the solution, it works by redirecting touch event to click event like this:
if (is_touch_device()) {
var all_links = document.querySelectorAll('a[href]')
var event = new Event('click');
for (var index = 0 ; index < all_links.length ; ++index) {
all_links[index].addEventListener("touchend", function() {
all_links[index].dispatchEvent(event)
});
}
}
function is_touch_device() {
return 'ontouchstart' in window // works on most browsers
|| navigator.maxTouchPoints; // works on IE10/11 and Surface
}

How can i load a function that starts from loadstart to loadstop in inAppBrowser

I am loading a pdf from google drive in cordova inappbrowser. I want to hide the sign in button. I call this code at my loadstop and it works.
function loadPDF(url){
// var myCallback = function() {
// setTimeout(function(){
// var appBanners = document.getElementsByClassName('drive-viewer-toolstrip-rgt-panel'), i;
// for (var i = 0; i < appBanners.length; i ++) {
// appBanners[i].style.display = 'none';
// }
// },500);
// }
var ref = cordova.InAppBrowser.open(url, '_blank', 'location=no', 'hidden=yes');
// ref.addEventListener('loadstart', function() {
// ref.executeScript({code: myCallback});
// });
ref.addEventListener('loadstop', function() {
ref.insertCSS({code: ".drive-viewer-toolstrip-rgt-panel{display: none !important;opacity: 0 !important;}"});
});
}
But the issue is that the button appears for 1 or 2 seconds. I don't want that. I used the executeScript as well to hide the button element but it doesn't work for some reason. Can any1 help me here? I am taking help from here but I can't seem to get it right. Any ideas?

Using JQuery on a window reference?

Can you use JQuery on a window reference? I have tried the following with no luck.
function GetDiPSWindow() {
var DiPSURL = "/DiPS/index";
var DiPSWindow = window.open("", "DiPS", "toolbar=no,location=no,status=no,menubar=no,scrollbars=yes,resizable=no,width=520,height=875");
if (DiPSWindow.location.href === "about:blank") {
DiPSWindow.location = DiPSURL;
}
return DiPSWindow;
}
function AddRecipient(field, nameId) {
// Get window
var win = GetDiPSWindow();
// Attempt 1
$(win.document).ready(function () {
var input = win.document.getElementById(field + "_Input");
input.value = nameId;
});
// Attempt 2
$(win).ready(function () {
var input = win.document.getElementById(field + "_Input");
input.value = nameId;
});
// Attempt 3
$(win).load(function () {
var input = win.document.getElementById(field + "_Input");
input.value = nameId;
});
}
Am I making a simple mistake?
EDIT For some reason, win.document.readyState is "complete". Not sure if that makes a difference.
I have also tried:
View contains:
<script>var CallbackFunction = function() {}; // Placeholder</script>
The method:
function AddRecipient(field, nameId) {
var DiPSURL = "/DiPS/index";
if (deliveryChannel === undefined) {
deliveryChannel = 0;
}
var DiPSWindow = GetDiPSWindow();
if (DiPSWindow.location.href === "about:blank") {
DiPSWindow.location = DiPSURL;
DiPSWindow.onload = function () { DiPSWindow.CallbackFunction = AddRecipient(field, nameId) }
} else {
var input = DiPSWindow.document.getElementById(field + "_Input");
input.value = input.value + nameId;
var event = new Event('change');
input.dispatchEvent(event);
}
}

The answer is.... kinda. it depends on what you are doing.
You can use jquery on the parent page to interact with a page within an iframe, however, anything that requires working with the iframe's document object may not work properly because jQuery keeps a reference of the document it was included on and uses it in various places, including when using document ready handlers. So, you can't bind to the document ready handler of the iframe, however you can bind other event handlers, and you can listen for the iframe's load event to know when it is absolutely safe to interact with it's document.
It would be easier though to just include jquery within the iframe itself and use it instead. It should be cached anyway, so there's no real detriment to performance by doing so.

div with an id wont accept any event handlers JavaScript. No Jquery

Im trying to pause a timed slideshow when you're hovering over a div
<div id="play_slide" onMouseOver="clearTimeout(playTime)"></div>
If i put onMouseOver="clearTimeout(playTime)" inside an li on the page, it'll pause, so I know my code is correct, it just wont work on the div! Also if i get rid of the id, it will alert when i put an alert function into an event handler
This is the js.
var playTime;
function playSlide()
{
var slideshow = document.getElementById("play_slide").style;
var images = new Array("an", "complete", "red", "thirteen");
indexPlay++;
if(indexPlay > images.length - 1)
{
indexPlay = 0;
}
slideshow.backgroundImage = "url('assets/images/play/"+images[indexPlay]+".png')";
playTime = setTimeout("playSlide()", 2500);
}
you can see this here: www.nicktaylordesigns.com/work.html

I would do it like this:
( and no inline script... just <div id="play_slide">Something</div> )
var playTime;
var indexPlay = 0;
var slideElement;
window.onload = function () {
slideElement = document.getElementById("play_slide");
slideElement.addEventListener('mouseenter', function () {
console.log('stop');
clearTimeout(playTime);
});
slideElement.addEventListener('mouseleave', function () {
console.log('continue');
playTime = setTimeout(playSlide, 2500);
});
playSlide();
}
function playSlide() {
var slideshow = slideElement.style;
var images = new Array("an", "complete", "red", "thirteen");
indexPlay++;
if (indexPlay > images.length - 1) {
indexPlay = 0;
}
slideshow.backgroundImage = "url('assets/images/play/" + images[indexPlay] + ".png')";
playTime = setTimeout(playSlide, 2500);
}
Fiddle

This issue is related to the script loading. Your script gets loaded after the DOM is processed so function doesn't get attached to the event.
If you are using jQuery then you can use below code.
$(function () {
$("#play_slide").mouseover(function(){
var playTime = 33;
clearTimeout(playTime);
});
});
If you don't want to use JQuery then you can do the same thing in JavaScript as below.
window.onload = function(){
document.getElementById("play_slide").onmouseover = function(){
var playTime = 33;
clearTimeout(playTime);
};
}

I got it! the div tag was somehow broken, I coded a div around it and gave it the event handlers and a class. That worked, then i simply changed the class to an id and got rid of the original div. Idk what was going on but it works now. Thanks for your suggestions!

Can you try this,
<div id="play_slide" onmouseover="StopSlide();">Stop</div>
<script>
var playTime;
var indexPlay;
function playSlide()
{
var slideshow = document.getElementById("play_slide").style;
var images = new Array("an", "complete", "red", "thirteen");
indexPlay++;
if(indexPlay > images.length - 1)
{
indexPlay = 0;
}
slideshow.backgroundImage = "url('assets/images/play/"+images[indexPlay]+".png')";
playTime = setTimeout("playSlide()", 2500);
}
function StopSlide(){
window.clearTimeout(playTime);
}
playSlide();
</script>

Changing erik vold toolbarbutton image on the fly

I'm trying to make a firefox extension with the SDK. (if I can avoid XUL i'm happy)
I'm using erik vold toolbarbutton
But I need to change the toolbar image on the fly.
My lib/main.js (background page) is :
var tbb = require("toolbarbutton").ToolbarButton({
id: "My-button",
label: "My menu",
image: Data.url('off.png'),
onCommand: function(){
Tabs.open(Data.url("signin.html"));
}
});
tbb.setIcon({image:Data.url('on.png')});
console.log(tbb.image);
tbb.moveTo({
toolbarID: "nav-bar",
forceMove: false // only move once
});
tbb.image is correct, but the button isn't refreshed.
I tried to change packages/toolbarbutton-jplib/lib/toolbarbutton.js
function setIcon(aOptions) {
options.image = aOptions.image || aOptions.url;
getToolbarButtons(function(tbb) {
tbb.image = options.image;
tbb.setAttribute("image", options.image); // added line
}, options.id);
return options.image;
}
But it doesn't seem to refresh...
Is erik vold lib enough for this kind of need ?

also be sure to update with this fix https://github.com/voldsoftware/toolbarbutton-jplib/pull/13/files

there is a setIcon method and a image setter that you can use to update the toolbar button's image

I had the same problem so I just wrote the code my self using this tutorial:
http://kendsnyder.com/posts/firefox-extensions-add-button-to-nav-bar
Try this, I rewrote my code to fit your needs:
var btn = null;
var btnId = 'My-button';
var btnLabel = 'My menu';
var btnIconOn = 'on.png';
var btnIconOff = 'off.png';
var {Cc, Ci} = require('chrome');
var self = require("sdk/self");
var mediator = Cc['#mozilla.org/appshell/window-mediator;1'].getService(Ci.nsIWindowMediator);
// exports.main is called when extension is installed or re-enabled
exports.main = function(options, callbacks) {
btn = addToolbarButton();
// do other stuff
};
// exports.onUnload is called when Firefox starts and when the extension is disabled or uninstalled
exports.onUnload = function(reason) {
removeToolbarButton();
// do other stuff
};
// add our button
function addToolbarButton() {
// this document is an XUL document
var document = mediator.getMostRecentWindow('navigator:browser').document;
var navBar = document.getElementById('nav-bar');
if (!navBar) {
return;
}
var btn = document.createElement('toolbarbutton');
btn.setAttribute('id', btnId);
btn.setAttribute('type', 'button');
// the toolbarbutton-1 class makes it look like a traditional button
btn.setAttribute('class', 'toolbarbutton-1');
// the data.url is relative to the data folder
btn.setAttribute('image', self.data.url(btnIconOff));
btn.setAttribute('orient', 'horizontal');
// this text will be shown when the toolbar is set to text or text and iconss
btn.setAttribute('label', btnLabel);
navBar.appendChild(btn);
return btn;
}
function removeToolbarButton() {
// this document is an XUL document
var document = mediator.getMostRecentWindow('navigator:browser').document;
var navBar = document.getElementById('nav-bar');
var btn = document.getElementById(btnId);
if (navBar && btn) {
navBar.removeChild(btn);
}
}
btn.addEventListener('click', function() {
Tabs.open(Data.url("signin.html"));
}, false);
tbb.setIcon({image:self.data.url(btnIconOn)});
