I am new to javascript and I don't quite know where I should be adding in my class that allows for the website to be translated.
I have a mobile nav that appears when the screen width is X small and in that nav I have numerous directional buttons that lead to other parts of the website, BUT two buttons (The english and Chinese translation buttons) don't work when being pressed.
I assume this is because I have not added the 'lang' class in my 'is-mobile' class but I am unaware of how to do this.
Here is my code
(function($) {
var $window = $(window),
$body = $('body'),
$header = $('#header'),
$banner = $('#banner'),
settings = {
banner: {
// Indicators (= the clickable dots at the bottom).
indicators: true,
// Transition speed (in ms)
// For timing purposes only. It *must* match the transition speed of "#banner > article".
speed: 1500,
// Transition delay (in ms)
delay: 5000,
// Parallax intensity (between 0 and 1; higher = more intense, lower = less intense; 0 = off)
parallax: 0.25

Where would I go to insert my lang class so that when it is in mobile nav the class is recognized? Thank you!
I figured it out!
I needed to add the class 'tr' into:
'class="tr link depth-' + indent + '"' +

Hello all of the knowers of javascript,
I have a little problem about javascript and would like one of you to help me to solve the problem.
If you know the 'PageRevealEffects' plugin there are multiple pages that in one HTML are turning on by javascript.
Here are the plugin documentation and demo version at the bottom of documentation: https://tympanus.net/codrops/2016/06/01/multi-layer-page-reveal-effects/
So my problem is I want to connect the navbar and logo click to the plugin,
http://bagrattam.com/stackoverflow/PageRevealEffects/
Here is the code by which it works
(function() {
$('.navbar-brand').click(function(){
$(this).data('clicked', true);
});
var n;
$('#nav a').click(function () {
n = $(this).parent().index() + 1;
});
var pages = [].slice.call(document.querySelectorAll('.pages > .page')),
currentPage = 0,
revealerOpts = {
// the layers are the elements that move from the sides
nmbLayers : 3,
// bg color of each layer
bgcolor : ['#52b7b9', '#ffffff', '#53b7eb'],
// effect classname
effect : 'anim--effect-3'
};
revealer = new Revealer(revealerOpts);
// clicking the page nav
document.querySelector('.navbar-brand').addEventListener('click', function() { reveal('bottom'); });
var navli = document.getElementsByTagName("ul");
for (var i = 0; i < navli.length; i++) {
navli[i].addEventListener('click', function() { reveal('top'); });
}
// triggers the effect by calling instance.reveal(direction, callbackTime, callbackFn)
function reveal(direction) {
var callbackTime = 750;
callbackFn = function() {
// this is the part where is running the turning of pages
classie.remove(pages[currentPage], 'page--current');
if ($('.navbar-brand').data('clicked')) {
currentPage = 0;
} else {
currentPage = n;
}
classie.add(pages[currentPage], 'page--current');
};
revealer.reveal(direction, callbackTime, callbackFn);
}
})();
http://bagrattam.com/stackoverflow/PageRevealEffects/
Here is the solution
var n;
$('#navbar a').click(function(){
if($(this).attr('id') == 'a') {
n = 0;
} else if($(this).attr('id') == 'b') {
n = 1;
} else if($(this).attr('id') == 'c') {
n = 2;
} else if($(this).attr('id') == 'd') {
n = 3;
} else if($(this).attr('id') == 'e') {
n = 4;
};
});
var pages = [].slice.call(document.querySelectorAll('.pages > .page')),
currentPage = 0,
revealerOpts = {
// the layers are the elements that move from the sides
nmbLayers : 3,
// bg color of each layer
bgcolor : ['#52b7b9', '#ffffff', '#53b7eb'],
// effect classname
effect : 'anim--effect-3'
};
revealer = new Revealer(revealerOpts);
// clicking the page nav
document.querySelector("#a").addEventListener('click', function() { reveal('top'); });
document.querySelector("#b").addEventListener('click', function() { reveal('top'); });
document.querySelector("#c").addEventListener('click', function() { reveal('top'); });
document.querySelector("#d").addEventListener('click', function() { reveal('top'); });
document.querySelector("#e").addEventListener('click', function() { reveal('top'); });
// triggers the effect by calling instance.reveal(direction, callbackTime, callbackFn)
function reveal(direction) {
var callbackTime = 750;
callbackFn = function() {
classie.remove(pages[currentPage], 'page--current');
currentPage = n;
classie.add(pages[currentPage], 'page--current');
};
revealer.reveal(direction, callbackTime, callbackFn);
}
I went of Ext's QuickTips to make this custom tooltip, that should show a tooltip when over an element with a 'my_tip' attribute.
For example,
<div class="some class" my_tip="This is my tip text">
When the page is loaded, it adds the following markup to the HTML, which is correct:
<div class="x-layer my_tool_tip_layer" id="ext-gen7" style="position: absolute; z-index: 20000; visibility: hidden; left: -10000px; top: -10000px;">
<div class="my_tool_tip" id="ext-gen8"> </div>
</div>
What should happen is when I hover the mouse over the element with the 'my_tip' attribute, it should update the above div's style attribute and replace   with the contents of the my_tip class.
Like this:
<div class="x-layer my_tool_tip_layer displayed" id="ext-gen7" style="position: absolute; z-index: 20000; visibility: visible; left: 160px; top: 30px;">
<div class="my_tool_tip" id="ext-gen8">This is my tip text</div>
</div>
I have a css file handling the styling of the tooltip, but my problem now is just getting the html to update to the correct events, which it is not doing.
Below is the javascript for the tooltip. Any help would be very much appreciated.
Thank you

i am working on an image slider here. I am trying to display the current number of image being displayed which has the opacity of 1 which is shown in front.
how can I check for opacity of an image and how an i check it again and again so that when the next image opacity is 1 the image number in Dom is displayed.
here is my code
html
<div id="Fader" class="fader">
<img class="slide" src="images/lounge/full/1.jpg" alt="bgImg" />
<img class="slide" src="images/lounge/full/2.jpg" alt="bgImg" />
<img class="slide" src="images/lounge/full/3.jpg" alt="bgImg" />
</div>
Now suppose I have 2.jpg with opacity 1 after some time how can i check which one has opacity of 1 that's being displayed on top?Thanks.
And here is the js Code
(function ($) {
function prefix(el) {
var prefixes = ["Webkit", "Moz", "O", "ms"];
for (var i = 0; i < prefixes.length; i++) {

waitForNext();
};
if (fading || activeNdx == newNdx) {
return false;

The easiest way would be to have a CSS class that has a opacity: 1.0 property, and then determining which slide currently has this class.
Let's say the class is .displayed, then you can find the active slide using $slides.find('.displayed').
And when moving to a new slide, just remove the class property after doing any necessary animations:
$slides.find('.displayed').animate({opacity: 0}).removeClass('.displayed');
The script below creates a slider widget the takes a definition list and turns it into a slide deck. Each dt element is rotated via css to become the "spine", which is used to reveal that dt's sibling dd element.
What I'm trying to do is to enhance it so that I can have the option to remove the spines from the layout and just use forward and back buttons on either side of the slide deck. To do that, I set the dt's to display:none via CSS and use the code under the "Remove spine layout" comment to test for visible.
This works fine to remove the spines, now I need to dynamically create 2 absolutely positioned divs to hold the left and right arrow images, as well as attach a click handler to them.
My first problem is that my attempt to create the divs is not working.
Any help much appreciated.

Creating elements in jQuery is easy:
$newDiv = $('<div />');
$newDiv.css({

'top': '10px',
'left': '10px'
});
$newDiv.on('click', function() {
alert('You have clicked me');
});
