Drag and Drop Feature HTML 5

Drag and Drop Feature HTML 5

Explaining the above-given example. Firstly, you need to mark the element (image in this case) as draggable which you want to drag.
  1. <img draggable="true">     
Now, you need to specify three attributes that will call the respective events or functions – ondragstart, ondragover, and ondrop.
  1. <div id="box" ondrop="drop(event)" ondragover="allowDrop(event)"></div>    
  2. <br> <img id="logo" src="dslogo.png" title="DS Logo" alt="DS Logo" draggable="true" ondragstart="drag(event)">    
Finally, calling the respective JavaScript function will do the job.
  • We are calling preventDefault() to prevent the browser default handling of the data (default action is to open as a link on the drop).
