Move absolute positioned divs off eachoter

I'm attempting to output on a page multiple 'labels' over an image using absolute positioned divs. Each of these divs has a unique number and are placed according to an x and y position on the map (these are percentage based so the image may be scaled).
As some of these labels may overlap, I need a way to either stop them from overlapping, or to essentially 'bump' them off eachother so they no longer overlap. (At this point, it doesn't matter if they are not in their correct position as long as they are near enough as there is a separate 'Pin' view).
They need to stay within the confines of their container and not overlap with eachother.
HTML:
<div id="labelzone">
<div class="label" style="left:0%;top:8%">001</div>
<div class="label" style="left:0%;top:11%">002</div>
<div class="label" style="left:1%;top:10%">003</div>
</div>
CSS:
#labelzone{
float:left;
width:500px;
height:500px;
border: 1px solid black;
position: relative;
}
.label{
position:absolute;
border:1px solid black;
background-color:white;
}
Jsfiddle: https://jsfiddle.net/79cco1oy/
There's a simple example of what I have as an output, these pins could be placed anywhere and there is no limit to how many is on the page, however there shouldn't be any occasion where there are too many to fit in the area.
I'm toying around with doing some form of collision detection and currently attempting to figure out an algorithm of some sort to get them to no longer overlap, and ensure they also don't overlap another item.

My solution is a bit more object oriented.
One object (LabelPool) will contain labels and will be in charge of storing and accomodating them so that they don't collide. You can customize the x/y values that you want to add/substract of the Label's positions in order to avoid their collision. The other object (Label) defines a Label and has some convenient methods. The collision algorithm that I used in LabelPool was taken from this post
var Label = function ($el) {
var position = $el.position(),
width = $el.outerWidth(true),
height = $el.outerHeight(true);
this.getRect = function () {
return {
x: position.left,
y: position.top,
width: width,
height: height
};
};
this.modifyPos = function (modX, modY) {
position.top += modY;
position.left += modX;
updatePos();
};
function updatePos() {
$el.css({
top: position.top,
left: position.left
});
}
};
var LabelPool = function () {
var labelPool = [];
function collides(a, b) {
return !(((a.y + a.height) < (b.y)) || (a.y > (b.y + b.height)) || ((a.x + a.width) < b.x) || (a.x > (b.x + b.width)));
}
function overlaps(label) {
var a = label.getRect();
return labelPool.some(function (other) {
return collides(a, other.getRect());
});
}
this.accomodate = function (label) {
while (labelPool.length && overlaps(label)) {
label.modifyPos(0, 1);// You can modify these values as you please.
}
labelPool.push(label);
};
};
var labelPool = new LabelPool;
$(".label").each(function (_, el) {
labelPool.accomodate(new Label($(el)));
});
Here's the fiddle.
Hope it helps.

Using js and jquery, you can find a basic collision engine based on left/top abs position and size of the label.
https://jsfiddle.net/Marcassin/79cco1oy/6/
Every time you want to add a Label, you check if the positionning is overlaping any existing div, in this case, you translate the new Label to position. This operation may not be the most beautiful you can find, there can be a long process time in case of lots of labels.
$(document).ready (function () {
addLabel (0, 8);
addLabel (0, 11);
addLabel (1, 10);
addLabel (2, 7);
});
function addLabel (newLeft, newTop)
{
var newLab = document.createElement ("div");
newLab.className = "label";
$(newLab).css({"left": newLeft+"%", "top": newTop + "%"});
var labels = $("#labelzone > div");
newLab.innerHTML = "00" + (labels.length + 1); // manage 0s
$("#labelzone").append (newLab);
var isCollision = false;
var cpt = 1;
do
{
isCollision = false;
$(labels).each (function () {
if (! isCollision && collision (this, newLab))
isCollision = true;
});
if (isCollision)
$(newLab).css({"left": (newLeft + cpt++) + "%",
"top": (newTop + cpt++) + "%"});
} while (isCollision);
}
function isInside (pt, div)
{
var x = parseInt($(div).css("left"));
var y = parseInt($(div).css("top"));
var w = $(div).width () + borderWidth;
var h = $(div).height ();
if (pt[0] >= x && pt[0] <= x + w &&
pt[1] >= y && pt[1] <= y + h)
return true;
return false;
}
function collision (div1, div2)
{
var x = parseInt($(div1).css("left"));
var y = parseInt($(div1).css("top"));
var w = $(div1).width () + borderWidth;
var h = $(div1).height ();
var pos = [x, y];
if (isInside (pos, div2))
return true;
pos = [x + w, y];
if (isInside (pos, div2))
return true;
pos = [x + w, y + h];
if (isInside (pos, div2))
return true;
pos = [x, y + h];
if (isInside (pos, div2))
return true;
return false;
}

Here's another implementation of collision detection close to what you asked for. The two main goals being:
move vertically more than horizontally (because boxes are wider than tall)
stay within a reasonable range from the origin
Here goes:
function yCollision($elem) {
var $result = null;
$('.label').each(function() {
var $candidate = $(this);
if (!$candidate.is($elem) &&
$candidate.position().top <= $elem.position().top + $elem.outerHeight() &&
$candidate.position().top + $candidate.outerHeight() >= $elem.position().top) {
$result = $candidate;
console.log("BUMP Y");
}
});
return $result;
}
function xCollision($elem) {
var $result = null;
$('.label').each(function() {
$candidate = $(this);
if (!$candidate.is($elem) &&
yCollision($elem) &&
yCollision($elem).is($candidate) &&
$candidate.position().left <= $elem.position().left + $elem.outerWidth() &&
$candidate.position().left + $candidate.outerWidth() >= $elem.position().left) {
$result = $candidate;
console.log("BUMP X");
}
});
return $result;
}
function fuzzyMoveY($elem, direction) {
var newTop = $elem.position().top + $elem.outerHeight() / 4 * direction;
// stay in the canvas - top border
newTop = (newTop < 0 ? 0 : newTop);
// stay in the canvas - bottom border
newTop = (newTop + $elem.outerHeight() > $("#labelzone").outerHeight() ? $("#labelzone").outerHeight() - $elem.outerHeight() : newTop);
// stay close to our origin
newTop = (Math.abs(newTop - $elem.attr("data-origin-top")) > $elem.outerHeight() ? $elem.attr("data-origin-top") : newTop);
$elem.css({'top': newTop});
}
function fuzzyMoveX($elem, direction) {
var newLeft = $elem.position().left + $elem.outerWidth() / 4 * direction;
// stay in the canvas - left border
newLeft = (newLeft < 0 ? 0 : newLeft);
// stay in the canvas - right border
newLeft = (newLeft + $elem.outerWidth() > $("#labelzone").outerWidth() ? $("#labelzone").outerWidth() - $elem.outerWidth() : newLeft);
// stay close to our origin
newLeft = (Math.abs(newLeft - $elem.attr("data-origin-left")) > $elem.outerWidth() ? $elem.attr("data-origin-left") : newLeft);
$elem.css({'left': newLeft});
}
function bumpY($above, $below) {
if ($above.position().top > $below.position().top) {
$buff = $above;
$above = $below;
$below = $buff;
}
fuzzyMoveY($above, -1);
fuzzyMoveY($below, 1);
}
function bumpX($left, $right) {
if ($left.position().left > $right.position().left) {
$buff = $right;
$right = $left;
$left = $buff;
}
fuzzyMoveX($left, 1);
fuzzyMoveX($right, -1);
}
$('.label').each(function() {
$(this).attr('data-origin-left', $(this).position().left);
$(this).attr('data-origin-top', $(this).position().top);
});
var yShallPass = true;
var loopCount = 0;
while (yShallPass && loopCount < 10) {
yShallPass = false;
$('.label').each(function() {
var $this = $(this);
$collider = yCollision($this);
if ($collider) {
bumpY($this, $collider);
yShallPass = true;
}
});
loopCount++;
}
console.log("y loops", loopCount);
var xShallPass = true;
var loopCount = 0;
while (xShallPass && loopCount < 10) {
xShallPass = false;
$('.label').each(function() {
var $this = $(this);
$collider = xCollision($this);
if ($collider) {
bumpX($this, $collider);
xShallPass = true;
}
});
loopCount++;
}
console.log("x loops", loopCount);
This is not production code obviously but please report back if it helps.

Add close button to popup

How do add a close button to the following popup by putting a cross on the target page?
Currently it closes if I click anywhere outside the box, but would prefer a Cross "X" on the box or the corner.

Page opens with this link
<a class="modal" href="javascript:void(0);">here</a>

Put an element in your source page (here page.php as you wrote) and give it a unique id or anything else (for example id="CloseModal"). And in your script, write this event handler:
$('body').on('click', '#CloseModal', function () {
closePopup(fadeOutTime);
});
If you don't want to change your source page, and make close button globally for all popups, change your modalPopup function and add these lines to it:
var closeDiv = document.createElement('div');
closeDiv.setAttribute('id', 'CloseModal');
closeDiv.innerHTML = '[CLOSE]';
popupDiv.appendChild(closeDiv);
These code will add the close tag to the popup itself. And jquery code that I wrote before, will handle the click of it.
Here is your final scripts and functions:
<script language="javascript">
$(document).ready(function() {
//Change these values to style your modal popup
var align = 'center'; //Valid values; left, right, center
var top = 100; //Use an integer (in pixels)

If you are using boostrap then use this code onclick of close button or image
$("#your-popup-id").modal('hide');
and if you are not using boostrap then this will work
$("#your-popup-id").hide();

Stop function when pressing ctrl jQuery

So I am making a little game where you have to press Ctrl to stop a div from jumping randomly.
However I can't get it working...
The jumpRandom function works fine, until i put the randomJump(){return false;}; inside the if (event.ctrlKey) {}. What should I do to get it working?
js:
$(document).ready(function() {
function randomFromTo(from, to){
return Math.floor(Math.random() * (to - from + 1) + from);
}
$( "#goal" ).bind('mouseenter keypress', function(event) {
if (event.ctrlKey) {
randomJump(){return false;};
}
});
$('#goal').mouseenter(randomJump);
function randomJump(){
/* get Window position and size
* -- access method : cPos.top and cPos.left*/
var cPos = $('#pageWrap').offset();
var cHeight = $(window).height() - $('header').height() - $('footer').height();
var cWidth = $(window).width();
// get box padding (assume all padding have same value)
var pad = parseInt($('#goal').css('padding-top').replace('px', ''));
// get movable box size
var bHeight = $('#goal').height();
var bWidth = $('#goal').width();
// set maximum position
maxY = cPos.top + cHeight - bHeight - pad;
maxX = cPos.left + cWidth - bWidth - pad;
// set minimum position
minY = cPos.top + pad;
minX = cPos.left + pad;
// set new position
newY = randomFromTo(minY, maxY);
newX = randomFromTo(minX, maxX);
$('#goal').fadeOut(50, function(){
$('#goal').fadeIn(700);
});
$('#goal').animate({
left: newX,
top: newY,
duration: 500
});
}
});

Try this:
$("#goal").bind('mouseenter keypress', function (e) {
randomJump(e);
});
function randomJump(e) {
if (!e.ctrlKey) {
//do normal stuff
} else {
//depending on how permanent you need this to be...
//$("#goal").unbind('mouseenter keypress');
}
return !e.ctrlKey;
}

Drag and Drop -JQuery

Im creating myself a drag functions just for my personal use so I can drag elements around. I'm having a problem. At the moment trying to make the drag so one you pick up the element you can drag it but once you drop it, it goes back to the original position. This is not working as you can see here. When I let go of #drag2 or #drag3 then it goes to the position of #drag1.
My Function:
function drag(el) {
var position = $(el).position();
var ptop = position.top;
var pleft = position.left;
var down = false;
$(el).mousedown(function(event) {
down = true;
$(this).css({
cursor: 'crosshair',
});
$(this).mousemove(function(event) {
if (down == true) {
$(this).css({
cursor: 'crosshair',
});
var w = $(this).width();
var h = $(this).height();
var left3 = (w / 2) + 7;
var top3 = (h / 2) + 7;
$(this).css({
cursor: 'crosshair',
left: (event.clientX) + (3 * 3) - left3,
top: (event.clientY) + (3 * 3) - top3
});
}
}).mouseup(function() {
down = false;
$(this).css({
cursor: 'default',
});
$(this).animate({
top: ptop,
left: pleft
}, 300);
});
});
}
I have to get the old position:
var position = $(el).position();
var ptop = position.top;
var pleft = position.left;
So should it not get the position of all of them and bring them self back to where they were? Any help will be appreciated.
EDIT: I DO NOT WANT TO USE ANY PLUGIN OR JQUERY UI, THANKS ANYWAYS

The solution is very simple
See this fiddle: http://jsfiddle.net/BggPn/4/
you define 1 var for left and 1 for top. All 3 the elements use the same variables. If you loop through the elements then you make a new scope where each element has it's own vars.
Working code:
$(document).ready(function() {
drag('#drag, #drag2, #drag3')
});
function drag(el) {
$(el).each(function(){
var position = $(this).position();
var ptop = position.top;
var pleft = position.left;
var down = false;
$(this).mousedown(function(event) {
down = true;
$(this).css({
cursor: 'crosshair',
});
$(this).mousemove(function(event) {
if (down == true) {
$(this).css({
cursor: 'crosshair',
});
var w = $(this).width();
var h = $(this).height();
var left3 = (w / 2) + 7;
var top3 = (h / 2) + 7;
$(this).css({
cursor: 'crosshair',
left: (event.clientX) + (3 * 3) - left3,
top: (event.clientY) + (3 * 3) - top3
});
}
}).mouseup(function() {
down = false;
$(this).css({
cursor: 'default',
});
$(this).animate({
top: ptop,
left: pleft
}, 300);
});
});
});
}
Make it a plugin:
$.fn.drag = function drag(){
return this.each(function(){
var position = $(this).position();
var ptop = position.top;
var pleft = position.left;
var down = false;
$(this).mousedown(function(event) {
down = true;
$(this).css({
cursor: 'crosshair',
});
$(this).mousemove(function(event) {
if (down == true) {
$(this).css({
cursor: 'crosshair',
});
var w = $(this).width();
var h = $(this).height();
var left3 = (w / 2) + 7;
var top3 = (h / 2) + 7;
$(this).css({
cursor: 'crosshair',
left: (event.clientX) + (3 * 3) - left3,
top: (event.clientY) + (3 * 3) - top3
});
}
}).mouseup(function() {
down = false;
$(this).css({
cursor: 'default',
});
$(this).animate({
top: ptop,
left: pleft
}, 300);
});
});
});
}
Now you can call it by:
$("#drag1, #drag2").drag();

2 thoughts:
1.) Why don't you use jQuery UI (draggable)?
2.) The idea of giving a selector in stead of an element is wrong, a selector can lead to multiple elements, and that's the first reason why it's failing. If you start with
function drag(selector) {
$(selector).each(function() {
var el = $(this);
//rest of code
}
}
it would be better. But I think you'll run into a few other problems eventually

The problem is whenever you're sending in the list of selectors '#drag, #drag2. #drag3' and your position variable only cares about the first one (try changing the order and you'll see they snap to the first in the list). If you want to go about it this way then you'll want to perform an each iteration over them to get the right values.

get the current position of div after drag and set via this
.mouseup(function() {
var position = $(this).position();
down = false;
$(this).css({
cursor: 'default',
});
$(this).animate({
top: position.top,
left: position.left
}, 300);

why don't you use drag and drop plugin. see this article
