This error made my menus disabled and more issues. I would appreciate for any help to solve this error.

I am fairly certain this has been answered before here.
For normal javascript you can use:
window.innerHeight - the inner height of the browser window (in
pixels)
window.innerWidth - the inner width of the browser window (in
pixels)

webrtc remote video not playing in phonegap ios app?

I have found quite a few similar qustions but they are mainly old and outdated and some of them provided a few pointers which I followed to no avail.
Basically, I'm tring to use webrtc and the phonegap iosrtc plugin to create a simple 2 way video chat.
I followed everything to the letter and I managed to show my own video in the app but the 'remote' video is not showing and I ant figure out what the issue is at all!
I have enabled the debugging in phonegap but I don't get any errors.
This is my complete code:

}
window.cordova.InAppBrowser.open(" https://vps267717.ovh.net/webrtc", "_blank", "location=no,toolbar=yes");
As you can see in my code, I have this:
if (event.type === 'remote') {
alert('remote');
video.setAttribute('class', 'othersvideo');
}
But this never fires for some reason!
I have spent the last 3 days trying to figure this out but I haven't had any luck.
So any help and advice would be appreciated.
Thanks in advance.

Delete specific item from local storage

I have a note taking application that im working on . Its made to look like Google Keep
It saves each note in local storage .
I would like to add a delete option to each of the notes (similar to Keep) , but don't know know to do it.

Something like this? Use a data attribute on a delete button and pass that as a parameter to a removeNote function.
HTML
<button class="delete" data-id="1">Delete note</button>
JS
$(document).on('click', '.delete', function () {
var id = $(this).data('id');
removeNote(id);
});
function removeNote(id) {
localStorage.removeItem(id);
}

Dynamic dojo/on event

I have a scenario where I want to generalize a page scrolling event on button click using dojo. I haven't been able to make a breakthrough for quite sometime. I'm a DOJO beginner, would like some pointers to get a good solution. I have a fiddle:
http://jsfiddle.net/sacnayak/Ej39D/3/
Pasting the code in again for first reference:
require(["dojo/fx", "dojox/fx/scroll", "dojo/dom", "dojo/dom-style", "dojo/on", "dojo/domReady!", "dojo/window", "dojo/dom-geometry", "dojo/_base/fx", "dojo/Deferred", "dojo/query"],
function (coreFx, easing, dom, style, on, ready, win, domGeometry, fx, Deferred, query) {
function asyncProcess() {
var deferred = new Deferred();
setTimeout(function () {
deferred.resolve("success");
}, 500);
return deferred.promise;
}
var currentActiveDomButton = query("#screens .screen.active .card-footer-button")[0];
console.log(currentActiveDomButton);
on(dom.byId(currentActiveDomButton.id), "click", function () {
var currentActiveDomNode = query("#screens .screen.active")[0];
console.log(currentActiveDomNode);
var screens = query("#screens .screen");
var nextActiveDiv;
for (i = 0; i < screens.length; i++) {
if (dojo.attr(currentActiveDomNode, "id") != dojo.attr(screens[i], "id")) {
nextActiveDiv = screens[i];
console.log(nextActiveDiv);
break;
}
}
fx.animateProperty({
node: currentActiveDomNode.id,
duration: 500,
properties: {
opacity: {
start: '1',
end: '0.5'
}
}
}).play();
var process = asyncProcess();
process.then(function () {
style.set(nextActiveDiv.id, "display", "block");
//dojo.byId(currentActiveDomButton.id).style.display = 'none';
dojox.fx.smoothScroll({
node: nextActiveDiv.id,
win: window
}).play();
require(["dojo/dom-class"], function (domClass) {
domClass.remove(currentActiveDomNode.id, "active");
domClass.add(currentActiveDomNode.id, "visited");
domClass.add(nextActiveDiv.id, "active");
currentActiveDomButton = query("#screens .screen.active .card-footer-button")[0];
console.log(currentActiveDomButton.id);
});
});
});
});

Was able to fix this. Used a dojo.forEach and set up a event listener for every button.
Here's the fiddle:
http://jsfiddle.net/sacnayak/Ej39D/8/
require(["dojo/fx", "dojox/fx/scroll", "dojo/dom", "dojo/dom-style", "dojo/on", "dojo/domReady!", "dojo/window", "dojo/dom-geometry", "dojo/_base/fx", "dojo/Deferred", "dojo/query", "dojo/dom-class", "dojo/NodeList-traverse"],
function (coreFx, easing, dom, style, on, ready, win, domGeometry, fx, Deferred, query, domClass) {
function asyncProcess() {
var deferred = new Deferred();
setTimeout(function () {
deferred.resolve("success");
}, 500);
return deferred.promise;
}
query(".card-footer-button").forEach(function (buttonNode) {
on(dom.byId(buttonNode.id), "click", function () {
//fetch the current active screen
var currentActiveDomNode = query("#screens .screen.active")[0];
var screens = query("#screens .screen");
var nextActiveDiv;
if (buttonNode.value == "Next") {
for (i = 0; i < screens.length; i++) {
if (dojo.attr(currentActiveDomNode, "id") != dojo.attr(screens[i], "id")) {
if (!domClass.contains(screens[i].id, "visited")) {
nextActiveDiv = screens[i];
break;
}
}
}
} else if (buttonNode.value == "Edit") {
nextActiveDiv = query("#" + buttonNode.id).parent(".screen")[0];
/*fx.animateProperty({
node: nextActiveDiv.id,
duration: 500,
properties: {
opacity: {
start: '0.5',
end: '1'
}
}
}).play();*/
}
fx.animateProperty({
node: currentActiveDomNode.id,
duration: 500,
properties: {
opacity: {
start: '1',
end: '0.5'
}
}
}).play();
var process = asyncProcess();
process.then(function () {
style.set(nextActiveDiv.id, "display", "block");
dojo.byId(buttonNode.id).style.display = 'none';
if(dojo.byId(buttonNode.id + 'Edit') !== null){
dojo.byId(buttonNode.id + 'Edit').style.display = 'block';
}
if (buttonNode.value == "Edit") {
//query(".card-footer-button").forEach(function (buttonArray) {
//if(buttonArray.value == "Next"){
// buttonArray.style.display = "none";
//}
//});
if (buttonNode.id.indexOf("Edit") != -1) {
//console.log('Here');
//console.log('index' + buttonNode.id.indexOf("Edit"));
//console.log('length' + buttonNode.id.length);
var start = 0;
var end = buttonNode.id.indexOf("Edit");
var associatedNextButtonNode = buttonNode.id.substring(start, end);
//console.log(associatedNextButtonNode);
dojo.byId(associatedNextButtonNode).style.display = 'block';
}
}
dojox.fx.smoothScroll({
node: nextActiveDiv.id,
win: window
}).play();
if(nextActiveDiv.style.opacity == '0.5'){
fx.animateProperty({
node: nextActiveDiv.id,
duration: 500,
properties: {
opacity: {
start: '0.5',
end: '1'
}
}
}).play();
}
require(["dojo/dom-class"], function (domClass) {
domClass.remove(currentActiveDomNode.id, "active");
domClass.remove(nextActiveDiv.id, "visited");
if (buttonNode.value == "Next") {
domClass.add(currentActiveDomNode.id, "visited");
}
domClass.add(nextActiveDiv.id, "active");
});

jQuery preload only works with ie on refresh

I`m having a problem with ie9 not always loading preloaded images.
Sometimes I haft to refresh the page and then it works.
$jQuery.fn.img_preloader = function(options){
var defaults = {
repeatedCheck: 550,
fadeInSpeed: 1100,
delay: 200,
callback: ''
};
var options = jQuery.extend(defaults, options);
return this.each(function(){
var imageContainer = jQuery(this),
images = imageContainer.find('img').css({opacity:0, visibility:'hidden'}),
imagesToLoad = images.length;
imageContainer.operations = {
preload: function(){
var stopPreloading = true;
images.each(function(i, event){
var image = jQuery(this);
if(event.complete == true){
imageContainer.operations.showImage(image);
}else{
image.bind('error load',{currentImage: image}, imageContainer.operations.showImage);
}
});
return this;
},showImage: function(image){
imagesToLoad --;
if(image.data.currentImage != undefined) { image = image.data.currentImage;}
if (options.delay <= 0) image.css('visibility','visible').animate({opacity:1}, options.fadeInSpeed);
if(imagesToLoad == 0){
if(options.delay > 0){
images.each(function(i, event){
var image = jQuery(this);
setTimeout(function(){
image.css('visibility','visible').animate({opacity:1}, options.fadeInSpeed);
},
options.delay*(i+1));
});
if(options.callback != ''){
setTimeout(options.callback, options.delay*images.length);
}
}else if(options.callback != ''){
(options.callback)();
}
}
}
};
imageContainer.operations.preload();
});
}

Try commenting the event.complete validation and going directly to the showImage event. It's not the best solution, but worked for me.
$jQuery.fn.img_preloader = function(options)
{
var defaults = {
repeatedCheck: 550,
fadeInSpeed: 1100,
delay: 200,
callback: ''
};
var options = jQuery.extend(defaults, options);
return this.each(function()
{
var imageContainer = jQuery(this),
images = imageContainer.find('img').css({opacity:0, visibility:'hidden'}),
imagesToLoad = images.length;
imageContainer.operations = {
preload: function(){
var stopPreloading = true;
images.each(function(i, event){
var image = jQuery(this);
imageContainer.operations.showImage(image);
/*if(event.complete == true){
imageContainer.operations.showImage(image);
}else{
image.bind('error load',{currentImage: image}, imageContainer.operations.showImage);
}*/
});
return this;
},showImage: function(image){
imagesToLoad --;
if(image.data.currentImage != undefined) { image = image.data.currentImage;}
if (options.delay <= 0) image.css('visibility','visible').animate({opacity:1}, options.fadeInSpeed);
if(imagesToLoad == 0){
if(options.delay > 0){
images.each(function(i, event){
var image = jQuery(this);
setTimeout(function(){
image.css('visibility','visible').animate({opacity:1}, options.fadeInSpeed);
},
options.delay*(i+1));
});
if(options.callback != ''){
setTimeout(options.callback, options.delay*images.length);
}
}else if(options.callback != ''){
(options.callback)();
}
}
}
};
imageContainer.operations.preload();
});
}

Replace this showimage function..
showImage: function (g) {
d--;
if (g.data.currentImage != undefined) {
g = g.data.currentImage;
}
if (b.delay <= 0) {
g.css("visibility", "visible").animate({
opacity: 1
}, b.fadeInSpeed);
}
if (d != 0) {
if (b.delay != 0) {
e.each(function (k, j) {
var h = a(this);
setTimeout(function () {
h.css("visibility", "visible").animate({
opacity: 1
}, b.fadeInSpeed)
}, b.delay * (k + 1))
});
if (b.callback != "") {
setTimeout(b.callback, b.delay * e.length)
}
} else {
if (b.callback != "") {
b.callback()
}
}
}
}
