Once you've inserted shapes, text boxes, SmartArt graphics, images, or other objects, you can open the Selection Pane to keep track of them all. Use the event.dataTransfer object with the setData() and getData() methods to transfer data in the drag-and-drop operation.Open the Selection Pane any time: On the Home tab, select Arrange > Selection Pane.

Call the event.preventDefault() on the dragenter and dragover event handlers to make an element a valid drop target.The dragenter, dragover, dragleave or drop events fire on the drop target.The dragstart, drag, and dragend events fire on the draggable element.Add the draggable property with the value of true to an element to make it draggable.

If you open the index.html and try to drag the yellow box, you’ll see the cursor indicating that you cannot drag: And we place another div element with the class item in the first box. Inside the drop-targets element, we placed three div elements with the same class box. container element to align the heading and drop-targets element.

It allows you to transfer data from the dragged element to the drop target. The dataTransfer object is a property of the event. To transfer data in a drag-and-drop action, you use the dataTransfer object. (See the example section for more information) Transfer data using dataTransfer object To turn an element into a valid drop target, you can override the default behavior of both dragenter and dragover events by calling the event.preventDefault() method in their corresponding event handlers. If you drop an element over a drop target that doesn’t allow to drop, the drop event won’t fire. However, they don’t allow dropping by default. Valid drop targetĪlmost all elements support the drop target events ( dragenter, dragover, dragleave, and drop). The target ( e.target) of the dragenter, dragover, dragleave, and drop events are the drop target elements. In case you drop the element on the target, the drop event fires instead of the dragleave event. When you drag the element outside of the boundary of the drop target, the dragover event stops firing and the dragleave event fires. The dragenter event fires as soon as you drag the element over a drop target.Īfter the dragenter event fires, the dragover event fires repeatedly as long as you’re dragging the element within the boundary of the drop target. When you drag an element over a valid drop target, these events fire in the following sequence: Therefore, you can customize its appearance based on your preferences. The target of all events ( e.target) is the element that is being dragged.īy default, the browser doesn’t change the appearance of the dragged element. The cursor changes to a no-drop symbol (a circle with a line through it) to indicate that you cannot drop the element on itself.Īfter the dragstart event fires, the drag event fires repeatedly as long as you drag the element.Īnd The dragend event fires when you stop dragging the element. When you hold a mouse button and begin to move the mouse, the dragstart event fires on the draggable element that you’re dragging. When you drag an element, these events fire in the following sequence: Code language: HTML, XML ( xml ) Events on draggable elements
