Making a div draggable to a new position and stay there - draggable

This is a newbie question about Kendo UI draggable. I tried to look at their examples but cant really get it.
I want to make a div draggable to another position. When setting this up I can drag the div, but it disappears when released, I want it to stay in the new place. I have tried this but it doesnt work.
$('.draggable').kendoDraggable({
axis: "x",
hint: Hint,
dragstart: DragStart,
drag: Drag,
dragend: DragEnd
});
function Hint (element) {
console.log("hint");
return element;
}
function DragStart(){
console.log("dragstart");
}
function Drag(){
console.log("draging");
}
function DragEnd(event) {
console.log("dragend");
console.log(event.x.location);
$('.draggable').css({'left': event.x.location});
}

I think this is what you want, and I made a Demo for it.
$('.draggable').kendoDraggable({
hint : function (original) {
return original.clone().addClass("ob-clone");
},
dragstart: function (e) {
$(e.target).addClass("ob-hide");
}
});
$('body').kendoDropTarget({
drop: function (e) {
var pos = $(".ob-clone").offset();
$(e.draggable.currentTarget)
.removeClass("ob-hide")
.offset(pos);
}
})
.draggable {
position: absolute;
background: red;
width: 100px;
height: 100px;
vertical-align: middle;
}
.ob-hide {
display: none;
}
.ob-clone {
background: #cccccc;
}

Split/reveal image with css translate-y on scroll

I would like to achieve the effect where one image is revealed over the other when scrolling the page.
You can see an example on livearealabs.com (new york / seattle). Does anybody know how to create it using CSS3?
Check out this jsfiddle to create the sliding effect.
The trick is to have one div rotated 60 degrees. You position it so that it covers the entire wrapper and the overflow is hidden. Then with javascript you just have to move the slice container either by changing the left property or by changing the translate-X property.
Here is the code:
HTML:
<div class="wrapper">
<div class="bg"></div>
<div class="slice" data-show="true"></div>
</div>
CSS:
.wrapper {
position: relative;
overflow: hidden;
width: 20em;
height: 10em;
}
.bg {
background-color: red;
width: 100%;
height: 100%;
}
.slice {
position: absolute;
top: -12em;
left: -8em;
width: 30em;
height: 30em;
background-color: blue;
-webkit-transform: rotate(-60deg);
}
JS:
var hidden = false;
$('.wrapper').click(function() {
console.log('click');
if (hidden) {
$('.slice').stop().animate({left: '-8em'}, 2000);
hidden = false;
} else {
$('.slice').stop().animate({left: '-34em'}, 2000);
hidden = true;
}
console.log('click end');
});
Also check out this jsfiddle for a similar sliding effect that can be achieved with CSS only.

I think I found your problem. It seems to be the change function, just remove it and you can sort your list.
I've not used kendoSortable but I would assume that it is already maintaining the array sort because you have bound the array to the kendoSortable. That's the purpose of binding, it keeps the data and elements in sync for you. What you're doing in the change event is simply undoing the work that the binding just did, that is, sort the elements AND the bound array.
As per telerik,
https://www.telerik.com/forums/sortable-and-moving-items-in-observable-arrays
You have to do this manually and attaching sortable to an array doesn't do anything automatically. So what you are doing is correct, however even though your changes reflect correctly in observable array it doesn't on screen.
So we have to trigger clear and change event, to sync UI with the array. There may be a better way invoke sync without having to clear out array but this was a hack that worked for me.
Here is a sample code where we clear the array and then re-insert which fixes the issue.
$("#sortable-basic").kendoSortable({
change: function (e) {
var daa = data.items.splice(e.oldIndex, 1);
data.items.splice(e.newIndex, 0, daa[0]);
var copiedArray = data.items.splice(0, data.items.length);
$.each(copiedArray,
function (index, item) {
data.items.push(item);
});
}
});

Click Thumbnail to Change Main Image?

After learning JS for about a month now and completing around 4 courses I am still unable to work out how to change an image when clicking a thumbnail! What I want to do is simple, I just want to change the Main Image when a thumbnail is clicked! In this example there are two thumbnail images in a div and a main image above them. I just want to change the main image when a thumbnail is clicked. I know this is DOM Manipulation and think it is: document.getElementById.....?
I have make a small page so that I can learn / try different things and and finally giving up and asking for help! The code is as follows:
#MainContainer {
position: relative;
margin:0px auto;
width: 500px;
height: 400px;
border: 1px solid black;
}
#MainImage {
position: absolute;
top: 10px;
left: 50px;
width: 398px;
height: 265px;
background: url(MainImage01.jpg);
border: 1px solid black;
}
#TNBodyContainer {
position: absolute;
top: 290px;
left: 100px;
border: 1px solid black;
width: 268px;
height: 88px;
}
#TNOne {
position: relative;
width: 133px;
height: 88px;
background: url(SmallImage01.jpg);
}
#TNTwo {
position: relative;
left:135px;
width: 133px;
height: 88px;
background: url(SmallImage02.jpg);
}
<body>
<div id="MainContainer">
<div id="MainImage"></div>
<div id="TNBodyContainer">
<div id="TNOne">
<div id="TNTwo"></div>
</div>
</div>
Thank you very much for any help.

You need to add some scripting to change the image when either of the thumbnails are clicked. This function is called when the page is loaded. Change the image names to suit.
This should be placed in the section of the html page.
<script>
window.onload = function() {
var mainImg = document.getElementById('Main');
document.getElementById('TNOne').onclick = function() {
mainImg.src = 'main1.jpg';
//alert('one clicked');
};
document.getElementById('TNTwo').onclick = function() {
mainImg.src = 'main2.jpg';
//alert('two clicked');
};
};
</script>
The two thumbnail divs become <img> tags with the same IDs.
Similarly the main <img> is defined also (with id="Main"). Now the elements
are clickable.
<div id="MainContainer">
<div id="MainImage">
<img id="Main" src="MainImage01.jpg"</img>
</div>
<div id="TNBodyContainer">
<img id="TNOne" src="thumb1.jpg"></img>
<img id="TNTwo" src="thumb2.jpg"></img>
</div>
</div>
Finally CSS for the thumbnails, here float is used to keep the thumbnails in the same line within the TNBodyContainer div.
TNOne {
width: 133px;
height: 88px;
float:left;
}
#TNTwo {
width: 133px;
height: 88px;
float:left;
}
To change the image in the CSS background property, you need to use
document.getElementById("MainImage").style.background
The right way to go is to add event listeners:
document.getElementById("TNOne").addEventListener("click", function (event) {
setImage(event);
}, false);
document.getElementById("TNTwo").addEventListener("click", function (event) {
setImage(event);
}, false);
}
They both call the same function, but with event it is possible to see which one "clicked" with "event.target.id".
You can then decide what you want to do with for instance a switch statement. basically saying: if event.target.id == "TNOne".
You can see all this I made you a fiddle: http://jsfiddle.net/djwave28/32pQD/3/
There are some slight changes in your HTML and CSS too.

Nivo Slider breaks after I navigate away and back to home page while using Ajax

I'm using a Nivo Slider in a website that uses Ajax to load its content. It saves the user from loading new pages every time they click on a link.
My problem is that when I load the home page initially, the slider works fine; but if I navigate away from that page then back to it, it just has the loading gif on a loop. Can anyone help?
My index.php is this:
<!DOCTYPE html>

(Note that my Nivo Slider initialization is inside slide.js and looks like this:)
$(window).load(function() {
$('#slider').nivoSlider({
effect: 'random', // Specify sets like: 'fold,fade,sliceDown'
slices: 16, // For slice animations
boxCols: 6, // For box animations
boxRows: 3, // For box animations
animSpeed: 1000, // Slide transition speed
pauseTime: 5000, // How long each slide will show
startSlide: 0, // Set starting Slide (0 index)
directionNav: false, // Next & Prev navigation
controlNav: false, // 1,2,3... navigation
controlNavThumbs: false, // Use thumbnails for Control Nav
pauseOnHover: false, // Stop animation while hovering
manualAdvance: false, // Force manual transitions
prevText: 'Prev', // Prev directionNav text
nextText: 'Next', // Next directionNav text
randomStart: false, // Start on a random slide
beforeChange: function(){}, // Triggers before a slide transition
afterChange: function(){}, // Triggers after a slide transition
slideshowEnd: function(){}, // Triggers after all slides have been shown
lastSlide: function(){}, // Triggers when last slide is shown
afterLoad: function(){} // Triggers when slider has loaded
});
});
The Ajax jQuery file I'm using is this:
$(document).ready(function() {
var hash = window.location.hash.substr(1);
var href = $('#links li a').each(function(){
var href = $(this).attr('href');
if(hash==href.substr(0,href.length-3)){
var toLoad = hash+'.php #cont';
$('#cont').load(toLoad)
}
});
$('#links li a').click(function(){
var toLoad = $(this).attr('href')+' #cont';
$('#cont').fadeOut('fast',loadContent);
$('#load').remove();
$('#wrap').append('<span id="load">LOADING...</span>');
$('#load').fadeIn('fast');
window.location.hash = $(this).attr('href').substr(0,$(this).attr('href').length-4);
function loadContent() {
$('#cont').load(toLoad,'',showNewContent());
}
function showNewContent() {
$('#cont').fadeIn('fast',hideLoader('fast'));
}
function hideLoader() {
$('#load').fadeOut('fast');
}
return false;
});
});
