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.

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();
});

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" );

I want to change class on two divs when I drop my span, and remove draggable.
I have this:
$( ".dragandrop" ).draggable({ snap: "#grid" });
$("#grid").droppable({
drop: function( event, ui ) {
$( this )
.addClass( "droped" )
}
});
This code add me .droppable only on first div, and doesn't add class "droped", I can't do removing .draggable. Can you help me?
First off, be careful using the same id for multiple elements. It can cause really weird issues (see this post).
Second, make sure you add the draganddrop class to the appropriate elements that you want to, well, drag and drop.
And you want to removed the draggable on an element once you dropped it? I think what you want looks something like this:
$( ".dragandrop" ).draggable({
snap: ".dragandrop" ,
stop: function(event, ui){
$( this ).addClass( "droped" );
$( this ).draggable( 'disable' );
}
});
$(".dragandrop").droppable({});
div{
padding: 20px;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/jqueryui/1.11.4/jquery-ui.min.js"></script>
<div id="grid-wrapper">
<div id="grid1" style="background:orange;" class="dragandrop">a</div>
<div id="grid2" style="background:red;" class="dragandrop">b</div>
<div id="grid3" style="background:green;" class="dragandrop">c</div>
<div id="grid4" style="background:yellow;" class="dragandrop">d</div>
</div>
You may also want to add in some logic to keep the active div on top.
I am using jQuery droppable and I am trying to redirect to another page once the draggable element is dropped.
Here is my code:
<script>
$(function() {
$( "#draggable" ).draggable();
$( "#droppable" ).droppable({
drop: function( event, ui ) {
window.location.href = 'Section8.php';
}
});
});
</script>
<div id="draggable" class="ui-widget-content">
</div>
<div id="droppable" class="ui-widget-header">
</div>
For some reason this doesn't do anything, anyone know why this is?
You need to use window.location= 'Section8.php' instead of window.location.href= ... The window.location.href property returns the URL of the current page.
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.
I am having trouble with jquery expand and collapse.
I am planning to have a read more function over my site and i want to make use of this example.
http://www.designgala.com/demos/collapse-expand-jquery.html
if you could see clicking the header expands the content and clicking twice gives a result of minimizing but my issue here is to show some part of the content like 30px height from the div and when the header is clicked it would expand and show the whole content.
I created a jsfiddle which shows a way to do what you are looking to do.
http://jsfiddle.net/cSvAB/2/
Here is the javascript:
$( '.section' ).each( function( index, value ){
$( value ).data( 'height', $( this ).height() );
$( value ).css( {height: 30} );
});
$( '.section .header' ).click( function(){
if( $( this ).data( 'expanded' ) ){
$( this ).parent().animate( {height: 30} );
$( this ).data( 'expanded', false );
}else{
$( this ).parent( ).animate( {height: $( this ).parent().data( 'height' )} );
$( this ).data( 'expanded', true );
}
});
and here is the HTML:
<div class="section">
<div class="header">Click to read more</div>
<div>Lots of text here</div>
</div>
<div class="section">
<div class="header">Click to read more</div>
<div>Lots of text here</div>
</div>
The only other important thing is that .section is given the css attribute overflow: hidden;
.section{ overflow: hidden; }
What you want is actually an Accordion. You can use jQuery UI's accordion if you want a more professional look. Here it is: jqueryui.com/accordion/
