How to avoid overlapping of div elements during draggable? - javascript

I am using around 8-10 div elements..all are resizable and draggable.. now i want to avoid overlapping of each element on other during resizable or draggable..how i can i do that? I feel javascript,html,css, jquery code for me is more helpful..pls help me...part of the code for 2 elements will be like this...
<!--Reizable and draggable for the HEADER widget**************-->
$(function() {
$( "#placeLabel" ).draggable();
$( "#placeLabel" ).resizable({
ghost: true,
handles: "n, e, s, w"
});
});
<!--Reizable and draggable for the TWITTER widget**************-->
$(function() {
$( "#twitterLabel" ).draggable();
$( "#twitterLabel" ).resizable({
ghost: true,
alsoResize: '#twt',
alsoResize: '#tweets',
handles: "n, e, s, w"
});
});

It sounds like z-index in css could help you out, but I'm not sure if that works in this case since I don't have any experience with draggables.
z-index:1; /* for the bottom div */
z-index:100; /* for the top div */
Have a try and see if it work.

How can I make draggable elements droppable instead of appending?

I have a simple drag n drop it is working fine as I expected
but,
Problem:
The only problem is the elements are appending
What I want:
I don't want to append the elements I just want that when I drag n drop the element
they appear as normally happen.
My Code:
$( "#editorDesignView" ).droppable({
accept: '.textTemplate',
drop: function( event, ui ) {
var html = '<div id="" style="background: #eee; width: 80%; margin: 10px auto; padding: 10px;"><p contenteditable="true" style="padding: 5px;">'+ui.draggable.text()+'.</p></div>';
$(html).appendTo(this).hide().slideDown();
}
});
Here is my fiddle.
UPDATE:
I don't want to remove or want the same element as in left side. I just want that when I drop the element I can drop it anywhere
UPDATED FIDDLE:
Fiddle. Please check the console for the result. I want the result to be printed on droppable are without appending it.
you want a same representation on right column, as in left. And you can drop in anywhere at right column.
$(function(){
$(".textTemplate").draggable({
helper: "clone",
zIndex: 2500,
});
$( "#editorDesignView" ).droppable({
accept: '.textTemplate',
drop: function( event, ui ) {
console.log(ui.draggable.text(), event, ui);
var html = '<div>'+ui.draggable.text()+'</div>';
$(html).appendTo(this).hide().slideDown();
}
});
});

Change the cursor to a crosshair when a button is dragged

Hello I need to turn the cursor into a crosshair while the user drags a button. The code below is not working:
$("button").draggable('cursor','crosshair');
To achieve this you can use cursor property of the draggable library, like this:
$("#draggable").draggable({
cursor: 'crosshair'
});
Alternatively, if you want to set a custom cursor through CSS you would need to use the start and end events of the jQuery draggable library to change the CSS cursor property of the ui.helper. Try this:
$("#draggable").draggable({
start: function(e, ui) {
ui.helper.addClass('dragging');
},
stop: function(e, ui) {
ui.helper.removeClass('dragging');
}
});
.dragging { cursor: url('http://i.imgur.com/6r4pI7U.png'), crosshair; }
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<script src="http://code.jquery.com/ui/1.12.0/jquery-ui.min.js"></script>
<div id="draggable">
<p>Drag me</p>
</div>
From the jQuery UI docs https://api.jqueryui.com/draggable/
$( ".selector" ).draggable({
cursor: "crosshair"
});
Or if it is already initialized
$( ".selector" ).draggable( "option", "cursor", "crosshair" );

Jquery Drag and Drop on Ajax loaded Div

I want to be able to drag an element on the page into a droppable element inside an ajax loaded div. I can get the code to work when I place the droppable element in the regular page but not when i have the same element on the ajax loaded div. Im pretty sure its because of the way I'm calling scripts and how they load on the dom, but I can't find the solution. Note: I have tried calling the code which loads the ajax content before calling jquery ui but that didn't work either.
Here is how I'm calling everything, I removed the extraneous code for brevity.
main page
<head>
<scripts -- jquery, jquery ui>
<script>
$(document).ready(function(){
$( "#site-preview" ).load( "/site/preview" );
});
</script>
</head>
<body>
<div class="draggable><img src=//etc/> </div>
//if I put this div here, I can drop to it, so i know the drop code works.
// <div class="droppable col-md-2" style="height:100px;border:1px solid gray"><p> </p></div>
<div id="site-preview"></div>
<script>
$(function() {
$( ".draggable" ).draggable({
helper:'clone',
appendTo: 'body',
scroll: false
});
$( ".droppable" ).droppable({
drop: function( event, ui ) {
$( this ).addClass( "ui-state-highlight" ).find( "p" ).html( "Dropped!" );
}
});
});
</script>
</body>
ajax loaded code
<div class="droppable col-md-2" style="height:100px;border:1px solid gray">
<p> </p>
</div>
This appends because you try to call the droppable on a non-existing element at that moment. To solve this, you could use the callback function that can be attached to the load function and run the rest after that.
$(document).ready(function(){
$("#site-preview").load("/site/preview", function() {
// Page loaded and injected
// We launch the rest of the code
$( ".draggable" ).draggable({
helper:'clone',
appendTo: 'body',
scroll: false
});
$( ".droppable" ).droppable({
drop: function( event, ui ) {
$( this ).addClass( "ui-state-highlight" ).find( "p" ).html( "Dropped!" );
}
});
});
});
You can find other information about the load function here. The callback can take arguments and can be used, for example to check if it's a 404 or not.
Well I was able to get it to work by adding the draggable/droppable code to the ajax loaded div itself.
So the above would be amended like so
ajax loaded code
<div class="droppable col-md-2" style="height:100px;border:1px solid gray">
<p> </p>
</div>
<script>
$(function() {
$( ".draggable" ).draggable({
helper:'clone',
appendTo: 'body',
scroll: false //stops scrolling container when moved outside boundaries
});
$( ".droppable" ).droppable({
drop: function( event, ui ) {
$( this ).addClass( "ui-state-highlight" ).find( "p" ).html( "Dropped!" );
}
});
});
</script>
And those script lines would be taken out of the main page
Ajax is Asynchronous. So if you call some ajax and then call some other command, the ajax will usually finish afterwards.
This is where callbacks are useful. Try adding a callback to the ajax load call as shown here: http://api.jquery.com/load/
Something like:
$( "#site-preview" ).load( "/site/preview", function(){
$( ".droppable" ).droppable({
drop: function( event, ui ) {
$( this ).addClass( "ui-state-highlight" ).find( "p" ).html( "Dropped!" );
}
});
});
Side note: you should probably start using scripts instead of <script> tags.

jQuery-UI draggable/droppable Jumping

I'm not new to code here, but this is my first question on SO, so if my etiquette is off excuse me just this once. I've looked around for support on this, and it doesn't seem many people are running into this problem.
I'm playing with jQuery-UI for the dragging and dropping elements, and for the most part it's working fine. However when I drag something from a 'tabbed' div into a droppable area it jumps a couple hundred pixels below it. It's especially odd because I've got it set to revert it's position on an invalid drop, and that's working, but it ignores this rule on the first drop that makes it jump. I'm not sure if this is something in the CSS position style, or if I'm not setting my UI attributes correctly.

Hit the consumables tab > drag the item into the bin. You should see the behavior I'm describing. I'm using jQuery 1.10.2 and jQuery UI 1.10.4
This is all the code for the app:
<link href="css/pepper-grinder/jquery-ui-1.10.4.custom.css" rel="stylesheet">
<style>
#potion { width: 24px; height: 24px; position:relative;}
#tabs { width: 500px; height: 100px;}
#droppable { width: 500px; height: 100px;}
.inventoryTab { height: 40px; }
</style>
<!-- libraries -->
<script src="js/jquery-1.10.2.js"></script>
<script src="js/jquery-ui-1.10.4.custom.js"></script>
<!--functions -->
<script>
//functions
$(function() {
//Dragable Elements
$( ".draggable" ).draggable({ revert: "invalid"});
//Hover Text
$( document ).tooltip();
//droppable elements
$( "#droppable" ).droppable({
drop: function( event, ui ) {
$( this )
.addClass( "ui-state-highlight" )
.find( "p" )
.html( "FULL!" );
$(ui.draggable).appendTo($(this));
}
});
//Tab Interface
$( "#tabs" ).tabs();
});
</script>
</head>
<body>
<!-- Inventory tabs-->
<div id="tabs">
<ul>
<li>Equipment</li>
<li>Consumables</li>
<li>Items</li>
</ul>
<div id="tabs-1" class="inventoryTab" >
</div>
<div id="tabs-2" class="inventoryTab" >
<div id="potion" class="draggable">
<img src="sprites/potion.png" alt="potion" title="Minor Health Potion">
</div>
</div>
<div id="tabs-3" class="inventoryTab" >
</div>
</div>
<br>
<!-- The Bin --->
<h1>The BIN</h1>
<div id="droppable" class="ui-widget-header">
<p>Empty!</p>
</div>
UPDATE: I've come up with a bandaid solution that sets an exact position, that I suppose I could change using variables based on how many objects are in the bin. Check our this code for droppable event:
//droppable elements
$( "#droppable" ).droppable({
drop: function( event, ui ) {
$( this )
.addClass( "ui-state-highlight" )
.find( "p" )
.html( "FULL!" );
$(ui.draggable).appendTo($(this));
$(ui.draggable).css({
'top': '10px',
'left': '10px'
});
}
});
I'd prefer it if the object got the mouse position when it was dropped, but that's where my jQuery is failing me right now. I'll keep looking.
JSFIDDLE
It seems like you don't need this line $(ui.draggable).appendTo($(this));
//functions
$(function () {
//Dragable Elements
$(".draggable").draggable({
revert: "invalid"
});
//Hover Text
$(document).tooltip();
//droppable elements
$("#droppable").droppable({
drop: function (event, ui) {
$(this)
.addClass("ui-state-highlight")
.find("p")
.html("FULL!");
//$(ui.draggable).appendTo($(this)); // comment this out
}
});
//Tab Interface
$("#tabs").tabs();
});

Jquery draggable and droppable, switch to originalPosition another draggable

I'm working with Jquery UI draggable and droppable.
I have a container that accepts all the divs of the .category1 class, and what I have to do is:
If I put a div into the container that already has another div, revert the old div back to the
original position.
This is the code I have:
$(document).ready(function () {
$(function () {
$("#Part1").draggable({ revert: "invalid", snap: "#Part1Container", snapMode: "inner"
});
$("#Part1Container").droppable({
accept: ".category1",
drop: function (event, ui) {
//Some other logic
}
}
});
And the Html
<div id="Part1" class="ui-widget-content category1"></div>
<div id="Part2" class="ui-widget-content category1"></div>
I want the Part1 to be back to the original position if I insert Part2 in the container, and viceversa. And this has to work for n divs of the same class.
Any suggestions?
Tnx in advance :)
I solved it by assigning it a class when it goes into the container the first time, and then delete it when moving another div
$(".inCategory2").animate({
top: 0,
left: 0
}).removeClass("inCategory2");
ui.draggable.addClass("inCategory2");
