fadeout div in prototype - prototypejs

I need fadeout a div in my page using prototype. How can I fadeout following jquery code in prototype?
$('.exercise-main .content .loading-failure').fadeOut(function(){
//my code
}

I think you will need to use script.aculo.us (which is an excellent add-on to the fantastic prototype.js) so as to achieve the Fade effect.
Basic Syntax
new Effect.Fade('id_of_element', [options]);
OR
new Effect.Fade(element, [options]);
Complete Code.
<html>
<head>
<title>script.aculo.us examples</title>
<script type="text/javascript"
src="/javascript/prototype.js"></script>
<script type="text/javascript"
src="/javascript/scriptaculous.js?load=effects"></script>
<script type="text/javascript">
function FadeEffect(element){
new Effect.Fade(element,
{ duration:1});
}
function ShowEffect(element){
new Effect.Appear(element,
{duration:1, from:1.0, to:1.0});
}
</script>
</head>
<body>
<div onclick="FadeEffect('hideshow')">
Click me to fade out the image
</div>
<br />
<div onclick="ShowEffect('hideshow')">
Click me to display the image once again
</div>
<br />
<div id="hideshow">
<img src="/images/scriptaculous.gif" alt="script.aculo.us" />
</div>
</body>
</html>

I myself have used prototype.js and this add-on very heavily so just in case you face any issue, feel free to comment.. :-)

HTML2Canvas Screenshot Div

I am converting div element to image or screenshot. I've search throughout the internet and found out about html2canvas. I tried using it but no luck. Is there anyone who knows how to make it work? Here is my source code.
<html>
<head>
<title> Screenshot </title>
</head>
<body>
<div id="container">
<h1> Screen shot me </h1>
</div>
<button onclick = "screenshot()"> Capture </button>
</body>
<script src="https://cdnjs.cloudflare.com/ajax/libs/html2canvas/0.4.1/html2canvas.min.js"></script>
<script>
function screenshot(){
html2canvas(document.getElementById('container')).then(function(canvas){
document.body.appendChild(canvas);
})
}
</script>
</html>
My error keeps saying
Uncaught TypeError: html2canvas(...).then is not a function
at screenshot
at HTMLButtonElement.onclick. Did I miss something?
Im using Laravel 5.6 with NPM. Thankyou in advance!
Tested Chrome, Firefox ok, IE 11 needs adding 2 extra js library to support promise.
function takeSnapShot() {
html2canvas(document.querySelector("#capture")).then(function(canvas) {
document.querySelector("#newCanvas").appendChild(canvas);
});
}
<script src="https://cdn.jsdelivr.net/npm/es6-promise#4/dist/es6-promise.min.js"></script>
<script src="https://cdn.jsdelivr.net/npm/es6-promise#4/dist/es6-promise.auto.min.js"></script>
<script src="https://html2canvas.hertzen.com/dist/html2canvas.min.js"></script>
<div id="capture" style="padding: 10px; background: #f5da55">
<h4 style="color: #000; "> Screen shot me </h4>
</div>
<input type="button" value="Capture" onclick="takeSnapShot()"/>
<div id="newCanvas"></div>

CKEditor not working

I just downloaded CKEditor to use the WYSIWYG editor on my website, but this code:
<div id="editor">
This is a test
</div>
<script>
CKEDITOR.replace( 'editor' );
</script>
Or this code:
<textarea id="editor">
this is a test
</textarea>
<script>
CKEDITOR.replace( 'editor' );
</script>
Is only making the div and the textarea hide, no WYSIWYG editor is being shown.
The sample page is working and for my page the CSS and JS are both loaded.
What can be the problem?
Edit:
When I use their example code (stated here: http://docs.ckeditor.com/#!/guide/dev_installation)
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>A Simple Page with CKEditor</title>
<!-- Make sure the path to CKEditor is correct. -->
<script src="../ckeditor.js"></script>
</head>
<body>
<form>
<textarea name="editor1" id="editor1" rows="10" cols="80">
This is my textarea to be replaced with CKEditor.
</textarea>
<script>
// Replace the <textarea id="editor1"> with a CKEditor
// instance, using default configuration.
CKEDITOR.replace( 'editor1' );
</script>
</form>
</body>
</html>
It has the same behaviour (correct JS file is being loaded).
Check first that you have no error on javascript.
Check with firebug.
I added all the important files and It's working now

How to get the html of CKEditor

I am diving in the deep end of this magic world of HTML. I have the CKEditor woring and myFunction produces the alert. I need to get the HTML of the text in the editor.
I got this from another post:
CKEDITOR.instances.textarea.on( 'instanceReady', function( instanceReadyEventObj )
{
var editorInstanceData = CKEDITOR.instances.textarea.getData();
alert( editorInstanceData );
});
I could not comment or reply to the post as I don't have enough points so I have to ask a duplicate.
I have the alert working and pasted the code in myFunction but I get the error in the console Uncaught TypeError: Cannot call method 'on' of undefined.
<!DOCTYPE html>
<html>
<head>
<script>
function myFunction()
{
var htmldata = CKEDITOR.instances.Editor.document.getBody().getHtml();
alert(htmldata);
}
</script>

I've tried moving into different place but I still get the same error.

MrWarby.
Before your SCRIPT in HEAD add two more lines:
<script type="text/javaScript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.1/jquery.min.js"></script>
<script src="/ckeditor/ckeditor.js"></script>
But change path to CkEditor script.

Jquery background slide show with gallery

Does anyone know of a jquery plugin that has a background slide show and a gallery that changes background images every time someone opens the site or every hour or so?
There are lot of jQuery slideshow plugins. I would recommend you to look at the following:
Slide JS - http://www.slidesjs.com/
<head>
<title>Title</title>
<style type="text/css" media="screen">
.slides_container {
width:570px;
height:270px;
}
.slides_container div {
width:570px;
height:270px;
display:block;
}
</style>
<script src="http://code.jquery.com/jquery-latest.min.js"></script>
<script src="slides.js"></script>
<script>
$(function(){
$("#slides").slides();
});
</script>
</head>
<body>
<div id="slides">
<div class="slides_container">
<div>
<img src="http://placehold.it/570x270">
</div>
<div>
<img src="http://placehold.it/570x270">
</div>
<div>
<img src="http://placehold.it/570x270">
</div>
<div>
<img src="http://placehold.it/570x270">
</div>
</div>
</div>
</body>

Default values in ko.observable property not showing

I am trying out knockoutjs at the moment, with my fairly rudimentary knowledge of javascript. I have set up a basic ASP.NET MVC 3 app for this purpose. Here's the snippet I set up in the Home/Index.cshtml view:
#if(false)
{
<script src="../../Scripts/jquery-1.6.3.js" type="text/javascript"></script>
<script src="../../Scripts/knockout-1.3.0beta.debug.js" type="text/javascript"></script>
}
#{
ViewBag.Title = "Home Page";
}
<script type="text/javascript">
var entryDataViewModel = {
registration: ko.observable("Registration"),
registeredName: ko.observable("Name"),
entryClass: ko.observable("Junior")
};
ko.applyBindings(entryDataViewModel);
</script>
<h2>#ViewBag.Message</h2>
<p>
Registration: <span data-bind="text: registration"></span><br />
Name: <span data-bind="text: registeredName"></span><br />
Class: <span data-bind="text: entryClass"></span><br />
To learn more about ASP.NET MVC visit http://asp.net/mvc.
</p>
For some weird reason nothing is showing, not even the default values. If I debug through Firebug the ViewModel is showing the properties as being empty too. Have I missed something here?
Many thanks,
Dany.
ADDED: the content of the _Layout.cshtml - it's all stock standard stuff, except for the addition of knockout, and using jquery 1.6.3
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<title>#ViewBag.Title</title>
<link href="#Url.Content("~/Content/Site.css")" rel="stylesheet" type="text/css" />
<script src="#Url.Content("~/Scripts/knockout-1.3.0beta.js")" type="text/javascript"></script>
<script src="#Url.Content("~/Scripts/jquery-1.6.3.min.js")" type="text/javascript"></script>
<script src="#Url.Content("~/Scripts/modernizr-1.7.min.js")" type="text/javascript"></script>
</head>
<body>
<div class="page">
<header>
<div id="title">
<h1>My MVC Application</h1>
</div>
<div id="logindisplay">
#Html.Partial("_LogOnPartial")
</div>
<nav>
<ul id="menu">
<li>#Html.ActionLink("Home", "Index", "Home")</li>
<li>#Html.ActionLink("About", "About", "Home")</li>
</ul>
</nav>
</header>
<section id="main">
#RenderBody()
</section>
<footer>
</footer>
</div>
</body>
</html>
The answer I voted above only worked when I tried it in a plain webpage - not when I tried it in my MVC view. As it turned out I put the script block in the wrong position. I moved it to the end of the view, after the page elements have been processed. The other option is to wrap it within $(document).ready() then you can put the script block containing ViewModel and call to ko.applyBindings() anywhere you want...
use $(document).load(function(){:
<script type='text/javascript'>
//<![CDATA[
$(document).load(function(){
var entryDataViewModel = {
registration: ko.observable("Registration"),
registeredName: ko.observable("Name"),
entryClass: ko.observable("Junior")
};
ko.applyBindings(entryDataViewModel);
});
//]]>
</script>
Have a look: http://jsfiddle.net/S8Rh5/ - it works just fine.
