When dragover to specific column i want to prevent that inserting into that column in js

When drag-over to specific column I want to prevent that inserting into that column. Inside of inserting I want show default ghost icon(disable) using javascript
$(document).ready(function () {
$(function () {
var kanbanCol = $('.panel-body');
kanbanCol.css('max-height', (window.innerHeight - 150) + 'px');
var kanbanColCount = parseInt(kanbanCol.length);
$('.scrumview').css('min-width', (kanbanColCount * 350) + 'px');
draggableInit();
});
function draggableInit() {
var sourceId;
$('[draggable=true]').bind('dragstart', function (event) {
sourceId = $(this).parent().attr('id');
// alert("SourceID "+sourceId)
event.originalEvent.dataTransfer.setData("text/plain", event.target.getAttribute('id'));
});
$('.panel-body').bind('dragover', function (event) {
event.preventDefault();
});
$('.panel-body').bind('drop', function (event) {
alert();
var children = $(this).children();
var targetId = children.attr('id');
// alert("TargetID " + targetId)

jQuery Pause Between Animation And Color Change

I want the div to fadeOut(), then when it's not visible to change the color and text, and then but only then, reappear.
Here's the code
var changeColor = function() {
var div = document.getElementById("div");
var p = document.getElementById("p");
var pText = p.innerHTML;
if (pText == "Click Me!") {
$(document).ready(function() {
$("#div").fadeToggle("fast");
}, function() {
$("#div").css("background-color", "aquamarine");
p.innerHTML = "More!";
}, function() {
$("#div").fadeToggle("fast");
});
} else if (pText == "More!") {
$(document).ready(function() {
$("#div").fadeToggle("fast");
}, function() {
$("#div").css("background-color", "coral");
p.innerHTML = "Click Me!";
}, function() {
$("#div").fadeToggle("fast");
});
} else {
return;
}
}
This is the link to codepen.io, the project My Project

DEMO - Change the javascript to the following:
var changeColor = function() {
var div = document.getElementById("div");
var p = document.getElementById("p");
var pText = p.innerHTML;
if (pText == "Click Me!") {
$("#div").fadeToggle("fast", function(){
$("#div").css("background-color", "aquamarine");
$("#div").fadeToggle("slow");
p.innerHTML = "More!";
});
} else if (pText == "More!") {
$("#div").fadeOut("fast", function(){
$("#div").css("background-color", "color");
$("#div").fadeIn("fast");
});
} else {
return;
}
}
Explanation:
Functions like fadeToggle can take a callback function which triggers after the animation is complete:
$("#div").fadeOut("fast", function(){
/*code here will trigger after animation is complete*/
});

How can I stop JS triggering when scrolling on touch devices

At the moment we are using the below script to create a lightweight lightbox for a wordpress site, which works perfectly on desktop, but the overlay is being triggered when just scrolling on a touch device if you scroll with your finger on one of the images, is there anyway to stop this happening?
<script>
var WHLightbox = {
settings: {
overlay: $('.portfolio-tile--overlay'),
imageCell: $('.cell-image, .portfolio-tile--image')
},
data: {
images: []
},
init: function() {
this.events();
this.buildImageData();
},
events: function() {
var self = this;
this.settings.imageCell.on('click touchend', function(e) {
e.preventDefault();
e.stopPropagation();
// set up the overlay
self._positionOverlay();
self._openOverlay();
self._preventScrolling();
// create the image slide
self._createImageSlide($(this));
});
this.settings.overlay.on('click touchend', function(e) {
e.preventDefault();
e.stopPropagation();
self._closeOverlay();
});
$('.portfolio-tile--overlay--controls--prev, .portfolio-tile--overlay--controls--next').on('click touchend', function(e) {
e.preventDefault();
e.stopPropagation();
});
$('.portfolio-tile--overlay--controls--prev').on('click touchend', function(e) {
e.preventDefault();
e.stopPropagation();
self.showPrev();
});
$('.portfolio-tile--overlay--controls--next').on('click touchend', function(e) {
e.preventDefault();
e.stopPropagation();
self.showNext();
});
},
// public functions
showPrev: function() {
var index = this.currentImageIndex();
if(index === 0) {
index = this.data.images.length;
}
this._createImageSlide(false, index-1);
},
showNext: function() {
var index = this.currentImageIndex();
if(index === this.data.images.length-1) {
// set to -1 because it adds 1 in the _createImageSlide call
index = -1;
}
this._createImageSlide(false, index+1);
},
currentImageIndex: function() {
if(this.settings.overlay.hasClass('open')) {
var imageUrl = $('.portfolio-tile--main-image').attr('src');
for(var i=0; i<this.data.images.length; i++) {
if(this.data.images[i].imageUrl === imageUrl) {
return i;
}
}
} else {
return false;
}
},
// image data
buildImageData: function() {
var self = this,
i = 0;
this.settings.imageCell.each(function() {
self.data.images[i] = {
imageUrl: self._getImagePath($(this))
}
i++;
});
},
// slide
_createImageSlide: function($el, index) {
var imagePath;
if(!$el) {
imagePath = this.data.images[index].imageUrl;
} else {
imagePath = this._getImagePath($el);
}
this.settings.overlay.find('.portfolio-tile--main-image').attr('src', imagePath);
},
_getImagePath: function($el) {
var imagePath,
spanEl = $el.find('span.js-cell-image-background'),
imgEl = $el.find('img.cell-image__image');
if(spanEl.length) {
imagePath = spanEl.css('backgroundImage');
imagePath = imagePath.replace('url(', '').replace(')', '');
} else if(imgEl.length) {
imagePath = imgEl.attr('src');
}
return imagePath;
},
// overlay
_positionOverlay: function() {
this.settings.overlay.css({
// position the overlay to current scroll position
top: $(window).scrollTop()
});
},
_openOverlay: function() {
this.settings.overlay.addClass('open');
},
_preventScrolling: function() {
$('html, body').addClass('no-scroll');
},
_reInitScrolling: function() {
$('html, body').removeClass('no-scroll');
},
_closeOverlay: function() {
this.settings.overlay.removeClass('open');
this._reInitScrolling();
}
};
WHLightbox.init();
</script>

You could use a library such as Modernizr to detect touch take a look at the answer to this question on detecting touch What's the best way to detect a 'touch screen' device using JavaScript?
With Modernizr only:
if (Modernizr.touch) {
alert('Touch Screen');
} else {
alert('No Touch Screen');
}
or with the use of jQuery & Modernizr you can do something like:
if($('html').hasClass('touch') === false) {
//run your code here
}

Thank you for your reply aharen, I managed to get it working by just changing touchend to tap and it seems to be working as intended now.

How to pause a .scrollTop() animation on mouseover? (jsfiddle included)

I am using the following jquery code to create a slow scrolling animation.
http://jsfiddle.net/fhj45f21/
Unfortunately I am having difficulties pausing the animation on mouse over. Could someone please have a look and give me a hint?
function Scroller(y){
this.times = 0;
this.moveInter = 0;
this.backInter = 0;
this.moveBack = function () {
var self = this;
clearInterval(this.moveInter);
this.backInter = setInterval(function () {
self.times -= 5;
y.scrollTop(self.times);
if (self.times == 0) {
return self.startMove();
}
}, 1);
}
this.move = function() {
var self = this;
this.moveInter = setInterval(function () {
self.times++;
y.scrollTop(self.times);
if (self.times == 1200) {
return self.moveBack();
}
}, 50);
}
this.startMove = function() {
this.times = 0;
var self = this;
if (this.backInter != null) {
clearInterval(this.backInter);
}
window.setTimeout(function () {
self.move();
}, 1000);
}
}
jQuery('.textBox').each(function () {
y = jQuery(this);
var scroller = new Scroller(y);
scroller.startMove();
});
Thanks a bunch!

Here you go: http://jsfiddle.net/nxk4vseq/
add an y.hover handler with functions for mousein and mouseout
var scrl=this;
y.hover(function(){
clearInterval(scrl.moveInter);
},function(){
scrl.move();
});

Jquery code works, javascript does not, what am i doing wrong?

Below is some code that has no jquery, but it is not working:
function start() {
var img = 0,
pic = ['nature', 'grass', 'earth', 'fall2', 'waterfall'],
slider = document.getElementsByClassName('slide_img'),
timerID = 0,
delay = 4000;
function back() {
img--;
if (img <= 0) {
img = pic.length - 1;
}
slider.src = 'pictures/' + pic[img] + '.jpg';
}
function go() {
img++;
if (img >= pic.length) {
img = 0;
}
slider.src = 'pictures/' + pic[img] + '.jpg';
}
document.getElementById('back').onclick = function() {
back();
}
document.getElementById('go').onclick = function() {
go();
}
slider.onmouseenter = function() {
clearTimeout(timerID);
}
document.getElementById('go').onmouseenter = function() {
clearTimeout(timerID);
}
document.getElementById('back').onmouseenter = function() {
clearTimeout(timerID);
}
slider.onmouseleave = function() {
clearTimeout(timerID);
auto();
}
function auto() {
timerID = setTimeout(function () {
go();
auto();
}, delay);
}
auto();
}
Here is what it is in jquery, this one works:
$('document').ready(function() {
var img = 0,
pic = ['nature', 'grass', 'earth', 'fall2', 'waterfall'],
slider = $('img.slide_img'),
timerID = 0,
delay = 4000;
function back() {
img--;
if (img <= 0) {
img = pic.length - 1;
}
slider.attr('src', 'pictures/' + pic[img] + '.jpg');
}
function go() {
img++;
if (img >= pic.length) {
img = 0;
}
slider.attr('src', 'pictures/' + pic[img] + '.jpg');
}
$('button#back').on('click', function() {
back();
});
$('button#go').on('click', function() {
go();
});
$(slider).on('mouseenter', function () {
clearTimeout(timerID);
});
$('button#go').on('mouseenter', function () {
clearTimeout(timerID);
});
$('button#back').on('mouseenter', function () {
clearTimeout(timerID);
});
$(slider).on('mouseleave', function () {
clearTimeout(timerID);
auto();
});
function auto() {
timerID = setTimeout(function () {
go();
auto();
}, delay);
}
auto();
});
What am i doing wrong, why is the first one not working. Im am trying to get rid of jquery so i dont have to include the source file.

You are not executing onload
try
var img = 0,
pic = ['nature', 'grass', 'earth', 'fall2', 'waterfall'],
slider,
timerID = 0,
delay = 4000;
window.onload=function() {
slider = document.getElementsByClassName('slide_img');
document.getElementById('back').onclick = function() {
back();
}
document.getElementById('go').onclick = function() {
go();
}
slider.onmouseover = function() {
clearTimeout(timerID);
}
document.getElementById('go').onmouseover = function() {
clearTimeout(timerID);
}
document.getElementById('back').onmouseover = function() {
clearTimeout(timerID);
}
slider.onmouseout = function() {
clearTimeout(timerID);
auto();
}
auto();
}
function auto() {
timerID = setTimeout(function () {
go();
auto();
}, delay);
}
function back() {
img--;
if (img <= 0) {
img = pic.length - 1;
}
slider.src = 'pictures/' + pic[img] + '.jpg';
}
function go() {
img++;
if (img >= pic.length) {
img = 0;
}
slider.src = 'pictures/' + pic[img] + '.jpg';
}

Use "onmouseover" and onmouseout" for canonical events:
slider.onmouseover = function() {
clearTimeout(timerID);
}
document.getElementById('go').onmouseover = function() {
clearTimeout(timerID);
}
document.getElementById('back').onmouseover = function() {
clearTimeout(timerID);
}
slider.onmouseout = function() {
clearTimeout(timerID);
auto();
}
And don't forget to define "slider" (the initial part is missing in your script):
var slider = document.querySelector('img.slide_img');

<body onload="start"></body>
The JavaScript start doesn't do anything. If you want to call a function, then you need to follow it with ().
This is a rather obtrusive way to deal with event handler assignment though. It is generally preferred to assign such things with JavaScript:
addEventListener('load', start);
See MDN for compatibility notes.
However, you don't have anything in your code that depends on the entire document being loaded. So you can simply:
<script>
start();
</script>
</body>
at the end of your document.
(You can put the whole script there for that matter, and keep it in an external file).
