How to prevent click while scrolling horizontally

I am using cards list with links and it is scrollable horizontally using mouse as well as arrows.
I Want to prevent clicking ( tags) while scrolling/dragging items left or right.
But clicking should work if i am not dragging items.
Here is what I am using in Javascript.
Code
var instance = $(".hs__wrapper");
$.each( instance, function(key, value)
{
var arrows = $(instance[key]).find(".arrow"),
prevArrow = arrows.filter('.arrow-prev'),
nextArrow = arrows.filter('.arrow-next'),
box = $(instance[key]).find(".hs"),
x = 0,
mx = 0,
maxScrollWidth = box[0].scrollWidth - (box[0].clientWidth / 2) - (box.width() / 2);
$(arrows).on('click', function() {
if ($(this).hasClass("arrow-next")) {
x = ((box.width() / 2)) + box.scrollLeft() - 10;
box.animate({
scrollLeft: x,
})
} else {
x = ((box.width() / 2)) - box.scrollLeft() -10;
box.animate({
scrollLeft: -x,
})
}
});
$(box).on({
mousemove: function(e) {
var mx2 = e.pageX - this.offsetLeft;
if(mx) this.scrollLeft = this.sx + mx - mx2;
},
mousedown: function(e) {
this.sx = this.scrollLeft;
mx = e.pageX - this.offsetLeft;
},
scroll: function() {
toggleArrows();
}
});
$(document).on("mouseup", function(){
mx = 0;
});
function toggleArrows() {
if(box.scrollLeft() > maxScrollWidth - 10) {
// disable next button when right end has reached
nextArrow.addClass('disabled');
} else if(box.scrollLeft() < 10) {
// disable prev button when left end has reached
prevArrow.addClass('disabled')
} else{
// both are enabled
nextArrow.removeClass('disabled');
prevArrow.removeClass('disabled');
}
}
});

Try adding a click event handler to the links which prevents default browser behaviour while scrolling. Then, remove the event handler, detecting when scrolling stops using e.g. this method.
var instance = $(".hs__wrapper");
$.each( instance, function(key, value)
{
var arrows = $(instance[key]).find(".arrow"),
prevArrow = arrows.filter('.arrow-prev'),
nextArrow = arrows.filter('.arrow-next'),
box = $(instance[key]).find(".hs"),
x = 0,
mx = 0,
maxScrollWidth = box[0].scrollWidth - (box[0].clientWidth / 2) - (box.width() / 2);
$(arrows).on('click', function() {
if ($(this).hasClass("arrow-next")) {
x = ((box.width() / 2)) + box.scrollLeft() - 10;
box.animate({
scrollLeft: x,
})
} else {
x = ((box.width() / 2)) - box.scrollLeft() -10;
box.animate({
scrollLeft: -x,
})
}
});
$(box).on({
mousemove: function(e) {
var mx2 = e.pageX - this.offsetLeft;
if(mx) this.scrollLeft = this.sx + mx - mx2;
},
mousedown: function(e) {
this.sx = this.scrollLeft;
mx = e.pageX - this.offsetLeft;
},
scroll: function() {
clearTimeout($.data(this, 'scrollTimer'));
$.data(this, 'scrollTimer', setTimeout(function() {
$(box).find('a').off('click');
}, 250));
toggleArrows();
$(box).find('a').on('click', function(e) {
e.preventDefault();
});
}
});
$(document).on("mouseup", function(){
mx = 0;
});
function toggleArrows() {
if(box.scrollLeft() > maxScrollWidth - 10) {
// disable next button when right end has reached
nextArrow.addClass('disabled');
} else if(box.scrollLeft() < 10) {
// disable prev button when left end has reached
prevArrow.addClass('disabled')
} else{
// both are enabled
nextArrow.removeClass('disabled');
prevArrow.removeClass('disabled');
}
}
});

How to make a element follow another element when dragging with jquery?

I need make a element follow another element when dragging, but with delay in the animation, is similar to "Chat heads of facebook's messenger", you know, the bubbles on Android.
This is my jQuery plugin:
// Draggable plugin
(function($) {
$.fn.drag = function(options) {
options = $.extend({
handle: null,
cursor: 'move',
draggingClass: 'dragging',
heads: null
}, options);
var $handle = this,
$drag = this;
if( options.handle ) {
$handle = $(options.handle);
}
$handle
.css('cursor', options.cursor)
.on("mousedown", function(e) {
var x = $drag.offset().left - e.pageX,
y = $drag.offset().top - e.pageY,
z = $drag.css('z-index');
$drag.css('z-index', 100000);
$(document.documentElement)
.on('mousemove.drag', function(e) {
var chats = $($(options.heads).get().reverse());
chats.each(function(i) {
$(chats[i]).css({ left: $drag.position().left - (10*i)});
$(chats[i]).css({top: $drag.position().top});
});
$drag.offset({
left: x + e.pageX,
top: y + e.pageY
});
})
.one('mouseup', function() {
$(this).off('mousemove.drag');
$drag.css('z-index', z);
var window_width = $(window).width();
var window_height = $(window).height();
var head_wpostion = $(options.heads).position().left;
var head_hposition = $(options.heads).position().top;
if( head_wpostion > (window_width / 2) )
{
$(options.heads).animate({left: (window_width-40)+"px"}, 300 );
$(options.heads).animate({left: (window_width-50)+"px"}, 300 );
}
else
{
$(options.heads).animate({left: "-15px"}, 300 );
$(options.heads).animate({left: "-5px"}, 300 );
}
if( head_hposition > (window_height - 50) )
{
$(options.heads).animate({top: (window_height-75)+"px"}, 200 );
$(options.heads).animate({top: (window_height-65)+"px"}, 200 );
}
if( head_hposition < 0 )
{
$(options.heads).animate({top: "15px"}, 150 );
$(options.heads).animate({top: "5px"}, 150 );
}
});
// disable selection
e.preventDefault();
});
};
})(jQuery);

the only way you can do that is if you position the element you want to to be dragged along relevant to the drag-able element.

Selected HTML DIV element draggable using JQueryUi draggable

I've an array of jQuery objects which are draggable.
What I want is when any element present in the array is dragged, All other elements should also be dragged.
Following is sample code that I have tried but I haven't got any success
$(event.target).parents('.ui-class-name').draggable({
disabled : false,
helper: function() {
var allSelectedEle = $($selected).map( function() {
return this.toArray()
});
return allSelectedEle;
}
});
Here $selected is the array of jQuery object
Update: Here is the sample markup

You need to save initial coordinates of elements, and update them while you dragging them (demo):
var els = $('.eq-ui-widget')
var coords = { x: 0, y: 0 }
function getSelected() {
return els.filter('.selected')
}
els
.draggable({
disbled: true,
drag: function(e, ui) {
getSelected().each(function() {
var orig = $(this).data().orig
$(this).css({
top: orig.top + (ui.position.top - coords.y) ,
left: orig.left + (ui.position.left - coords.x)
})
});
},
start: function(e, ui) {
coords.x = ui.position.left;
coords.y = ui.position.top;
getSelected().each(function() {
$(this).data().orig = $(this).position();
});
}
})
.on('click', function(event) {
if(!event.ctrlKey) return;
$(event.target).toggleClass('selected');
/*logic for dragging all selected elements simultaneously*/
var selected = getSelected()
els.draggable('option', 'disabled', true )
selected.draggable('option', 'disabled', false )
});

Unable to drop an element on mouseup event

Here is the jQuery code that I have written to drag multiple items at a time. It is draggable now but not droppable.
here is the code
$(document).on('click', function (e) {
var target = e.target;
if (!$(target).hasClass('a')) $('.selected').removeClass('selected');
});
$(document).delegate('.a', 'dblclick', function (e) {
$(this).addClass('selected');
});
$(document).delegate('.selected', 'mousedown', function (e) {
var div = $('<div></div>');
$('.selected').each(function () {
div.append($(this).clone());
});
div.prop('id', 'currentDrag');
$('#currentDrag').css({
left: e.pageX + "px",
top: e.pageY + "px"
});
$('body').append(div);
});
$(document).on('mouseup', function (e) {
var tgt = e.target;
var mPos = {
x: e.pageX,
y: e.pageY
};
$('.drop').each(function () {
var pos = $(this).offset(),
twt = $(this).width(),
tht = $(this).height();
});
if((mPos.x > pos.left) && (mPos.x < (pos.left + twt)) && (mPos.y > targPos.top) && (mPos.y < (pos.top + tht))) {
$(this).append($('#currentDrag').html());
}
$('.drop .selected').removeClass('selected');
$('#currentDrag').remove();
});
$('.drop').on('mouseup', function (e) {
$(tgt).append($('#currentDrag').html());
$('.drop .selected').removeClass('selected');
$('#currentDrag').remove();
});
$(document).on('mousemove', function (e) {
$('#currentDrag').css({
left: e.pageX + "px",
top: e.pageY + "px"
});
});
What is the pronblem with my code and how can I achieve this. here is the fiddle http://jsfiddle.net/mDewr/27/

I would really recommend trying to find a way to make the jQuery UI draggable and droppable libraries work for you. Then the question becomes,
similar to this one: How do I drag multiple elements with JavaScript or jQuery?.
Here's how we can apply one of the answers from that question to your problem. I'm using the jQuery UI multiple draggable plugin, the entire script of which can be found here: jquery.ui.multidraggable-1.8.8.js.
First let's simplify your HTML. By putting our draggable and dropable divs inside of elements, we don't have to apply redundant stylings to each one. Instead we can use the containing element to style
HTML
<div id="parent">
<div id="dragTargets">
<div>123</div>
<div>456</div>
<div>789</div>
</div>
<div id='dropTargets'>
<div></div>
<div></div>
</div>
</div>
Using the plugin we can call multidraggable on each of the drag divs. And droppable anywhere they can be dropped
JavaScript
$("#dragTargets div").multidraggable();
$("#dropTargets div").droppable();
Customize
We can control the appearance with styling. As an example, we'll make anything that can receive drops yellow, anything you're about to drop as red, and anything that has received an element green.
Here's some styling as an example in CSS
.ui-state-highlight { background: green; }
.ui-state-active { background: yellow; }
.ui-state-hover { background: red; }
And we'll control when these classes are applied with JavaScript:
$("#dropTargets div").droppable({
activeClass: "ui-state-active",
hoverClass: "ui-state-hover",
drop: function () {
$(this).addClass("ui-state-highlight")
}
});
Multi-Draggable
You should style the elements that are currently selected. The script will apply the class ui-multidraggable to all the currently selected elements. The following CSS will make it apparent to the user that their choice is selected.
.ui-multidraggable {
background: tan;
}
Check out this demo. Just hold down ctrl to select more than one of the divs and then drag all of them at once.
jsFiddle

There are few errors in you code. You can check errors on browser console.
To check elements over droppable area, you should check the drop area in the each loop, rather than after each loop. When moving mouse, you should better turn off selection to avoid selected text flashing
$(document).on('click', '.a', function (e) {
$(this).removeClass('selected');
});
$(document).on('dblclick', '.a', function (e) {
$(this).toggleClass('selected');
});
$(document).on('mousedown', '.selected', function (e) {
var dragMode = true;
var div = $('<div></div>');
$('.selected').each(function () {
div.append($(this).clone());
});
div.prop('id', 'currentDrag');
$('#currentDrag').css({
left: e.pageX + "px",
top: e.pageY + "px"
});
$('body').append(div);
//disable selection on dropping start
disableSelection();
$(document).on('mousemove.drop', function(e){
onDragging(e, dragMode);
});
$(document).on('mouseup.drop', function(e){
onDragEnd(e, dragMode);
});
});
function onDragEnd(e, dragMode){
if(!dragMode)
return;
var tgt = e.target;
var mPos = {
x: e.pageX,
y: e.pageY
};
$('.drop').each(function () {
var pos = $(this).position(),
twt = $(this).width(),
tht = $(this).height();
if((mPos.x > pos.left) &&
(mPos.x < (pos.left + twt)) &&
(mPos.y > pos.top) &&
(mPos.y < (pos.top + tht))) {
$(this).append($('#currentDrag').html());
}
});
$('.drop .selected').removeClass('selected');
$('#currentDrag').remove();
$('.onDrop').removeClass('onDrop');
//remove listener on docuemnt when drop end
$(document).off('mousemove.drop');
$(document).off('mouseup.drop');
//enable selection
enableSelection();
}
function onDragging(e, dragMode){
if(!dragMode)
return;
var p = $('body').offset();
var mPos = {
x: e.pageX,
y: e.pageY
};
$('#currentDrag').css({
left: mPos.x,
top: mPos.y
});
$('.drop').each(function () {
var pos = $(this).position(),
twt = $(this).width(),
tht = $(this).height();
$(this).toggleClass("onDrop",
(mPos.x > pos.left)
&& (mPos.x < (pos.left + twt))
&& (mPos.y > pos.top)
&& (mPos.y < (pos.top + tht))
);
});
}
function disableSelection(){
$(document).on("selectstart", function(){ return false; });
//firefox
$("body").css("-moz-user-select", "none");
}
function enableSelection(){
$(document).off("selectstart");
//firefox
$("body").css("-moz-user-select", "");
}
I updated your code: http://jsfiddle.net/mDewr/46/, may can help you.

There were several errors, which I'll not list now, but you can compare the old version with the new one.
$(document).on('dblclick', '.a', function (e) {
$(this).toggleClass('selected');
});
$(document).on('mousedown', '.selected', function (e) {
var div = $('<div id="currentDrag"></div>');
$('.selected').each(function () {
div.append($(this).clone(true));
});
var p = $('body').offset();
var l = e.pageX - p.left;
var t = e.pageY - p.top;
console.log(l, ', ', t);
$('body').append(div);
$('#currentDrag').css({
left: l,
top: t
});
});
$(document).on('mouseup', '.selected', function (e) {
$('.d').each(function(index, item){
var $i = $(item);
if (e.pageX >= $i.offset().left &&
e.pageX <= $i.offset().left + $i.width() &&
e.pageY >= $i.offset().top &&
e.pageY <= $i.offset().top + $i.height()) {
console.log('Dropped');
var $cl = $('#currentDrag').find('>*').clone(true);
$i.append($cl);
}
});
$('.selected').removeClass('selected');
$('#currentDrag').remove();
});
$(document).on('mousemove', function (e) {
var p = $('body').offset();
$('#currentDrag').css({
left: e.pageX - p.left,
top: e.pageY - p.top
});
});
http://jsfiddle.net/mDewr/43/
Everything should work perfectly in this version (this is an update).
PS: I've changed to 1.7+ jQuery, but you can easily change it back to <1.7. Also you don't need custom attributes, use css classes instead.

what I want to be able to do is change the slider image index with some sort of 'onclick' event. for example:
<img src="images/IMG_5137_s.jpg" width="100%" />
this however does not call the 'loadslide' function in the javascript file, probably because I don't know what I'm doing.... any help with this would be appreciated.
