jQuery Drag And Drop: Suggestions For Beginners

jquery drag and dropJavaScript users have long complained of the difficulty related to dragging and dropping images, emails and other functions on websites. Fortunately, this problem has since been kept to a minimum with the help of jQuery, an application created expressly with the purpose of making JavaScript easier to operate for the average user. jQuery drag and drop is far more intuitive, and thus, less frustrating than its traditional JavaScript counterpart. That being said, users still may run into a few snags as they strive to adjust to the jQuery drag and drop format. Such problems can be minimized when you follow the suggestion detailed below:

jQuery Plugins

Before you begin to use jQuery’s drag and drop function, you will want to ensure that the application and its library are actually integrated into your site. Additionally, you’ll be required to utilize the jQuery User Interface (UI) plugin, as this is the application responsible for such useful functions as drag and drop. If you need help establishing and navigating jQuery UI, you can find expert assistance through Udemy’s jQuery for Beginners course.

Transform Elements Into Draggable Functions

Typically, any element included on a webpage will automatically be fixed in place, be it an image, text or anything else. But with the help of jQuery, it is possible to turn fixed elements into draggable functions. The draggable indication simply needs to be added into the code. This can be accomplished by typing the following into the code: “$(‘#makeMeDraggable’).draggable();”. If you are struggling with coding basics and need a bit of a refresher before you conquer the drag and drop function, consider gaining expertise through JavaScript Basics with expert Paul Deitel.

Containing Draggable Functions

There may be circumstances in which you wish to limit the areas in which elements are able to be dragged and dropped on a webpage. A number of indicators can be added to the code to contain draggable functions to specified locations. The constraining indicators can also limit the number of elements that the user is able to drag and drop. For example, the indication ‘parent’ will ensure that only the chosen element is made draggable. Additionally, placing values x1, x2, y1 and y2 for parameters will limit the range of space in which a certain element can be dragged or dropped. Additional means of containing draggable functions can be learned through Marie Taylor’s Learn to Use jQuery UI Widgets.

Dropping The Draggable Element

The designation ‘drag and drop’ doesn’t really apply until you also make an element droppable. As with the initial draggable distinction, it is easy to include a droppable element in your coding. You will want to include the following function in the code: “$(‘#makeMeDraggable’).droppable()”. As with the draggable designation, there are ways in which you can add parameters for when, where and how an element is dropped. The event handler function known as “handleDropEvent()” should provide assistance in this endeavor. Additionally, you can learn several essential dropping parameters in jQuery Fundamentals Training.

jQuery’s draggable and droppable elements may seem complicated to the beginner, but the reality is that this application is far more intuitive than the standard JavaScript approach. Basic coding instructions should be sufficient for determining the exact manner in which a website’s element is dragged across the screen or dropped in a specific portion of the webpage.
