The in-house developed script for the resizing needed most of the time since it was calculating the widths of many DOM elements. The initialization of all the scripts took more than one second. It turned out that the JavaScripts for this feature performed very poorly on an application screen displaying a table with more than 40 columns.

We’ve also added a script element for our JavaScript code (which we’ll write in a moment).When I had the pleasure to work on a Web User Interface (UI) components library, I tried to optimize the client-side performance of a data table component providing Windows Explorer-like resizable columns. In the head area we’ve included the jQuery and jQuery UI libraries, and linked to a style.css file which we’ll build in Step 4. The HTML for our game is straightforward: View Demo » When playing the game, you can view the page source to see all the markup and JavaScript code. Try out the finished game by clicking the button below: The object of the game is to drop all 10 cards onto the correct slots. The user is presented with 10 number cards in random order, and 10 slots to drop the cards onto. We’re going to build a simple number cards game for young kids. Complete example: A drag-and-drop number cards gameĪ lot of the above concepts are easier to grasp when you see them working in a real example. Our function uses this object, along with the jQuery attr() method, to retrieve the ID of the dropped element ( "makeMeDraggable") and display it using alert(). The ui object has a draggable property, which is the draggable element that was dragged onto the droppable. As with draggable events, the handler needs to accept an event and a ui object. Here’s the changed code: function init() Īlert( 'The square with ID "' + draggable.attr('id') + '" was dropped onto me!' ) Īs you can see, we’ve created an event handler function called handleDropEvent() to respond to the droppable’s drop event. Let’s modify our draggable square example above, and set a few options.

For a full list of draggable options see the jQuery UI documentation. jQuery UI adjusts the z-index properties of the elements so that the currently-dragged element is brought to the top. By setting the stack option to a selector that matches the group of elements, you can make sure this happens. stack If you’re making a group of elements draggable - such as a set of cards - you usually want the currently-dragged element to appear on top of the other elements in the group. You can also set this option to true to snap the element to any other draggable element in the page. snap: '#snapToMe') to snap the draggable element to the edges of the selected element. For example, you can set this option to 'move' to turn the mouse pointer into a move cursor when dragging the element. You can do this by setting the containment option to various values: 'parent' Constrains the draggable to the parent element 'document' Constrains the draggable to the page 'window' Constrains the draggable to the browser window A selector Constrains the draggable to the selected element Array of 4 values ( ) Constrains the draggable to the specified rectangle cursor Changes the mouse cursor during dragging. Usually, though, you want to constrain the element to a certain portion of the page. Here are some options that you’ll probably want to use often: containment By default, you can drag a draggable element anywhere in the page. You can pass lots of options to draggable() to customize the behaviour of the draggable element, like this: The easiest way to include both libraries is to use Google’s CDN, as follows:

jQuery UI is a fantastic plugin for jQuery that adds all sorts of useful user interface widgets, effects and behaviours - including drag-and-drop. To add drag-and-drop functionality to your pages, you need to include both the jQuery library and the jQuery UI plugin.

In this tutorial we’ll take a look at how to create drag-and-drop interfaces with jQuery, and we’ll finish with a complete drag-and-drop example: a simple number cards game for kids. However, with modern browsers and a smattering of jQuery, drag-and-drop is now a piece of cake!

Dragging and dropping can be a very intuitive way for users to interact with your site or web app.
