dropzone.jd

A simple lib for creating styleable dropzones for files

• Call new DropZone(myElement) to initialize (On any element, event the body)
• Adds drop-available class to the dropzone element when a file is being dragged to the window. This is useful if you want to style your element to show that it is possible to drop the file on it.
• Adds drop-over class to the dropzone when the file is being dragged right over it.
• There is a backwards compatible jQuery plugin available, just npm install jquery.dropzone.

Remember, you need to preventDefault() on the 'drop' event, or the browser will use the default action on the dropped file, which is to download it or redirect to the file.

It's possible to instruct it to add an extra element inside the dropzone when a file is being dragged to the window, which will also receive the drop-over class.
This is useful for creating a dropzone on body, and having a styled dropzone element float above everything else.

This is done by passing an append option:

const myZone = new DropZone(document.body, { append: '<div class="dropzone-inner">' })

Now just listen to 'drop' event and take the file:

const myZone = new DropZone(document.body, {
    // This is optional, to add an internal element that you can style
    append: '<div class="full-drop-zone"><div class="description-wrapper"><div class="description">Release the file here...</div></div></div>',
    
    // This is optional, to selectively allow dropping
    allowDrop: (event) => {
        return dataTransfer.items.length > 0 && dataTransfer.items[0].kind === 'file';
    }
});

document.body.addEventListener('drop', function (event) {
    event.preventDefault();

    // Do something with the files
    console.log(event.originalEvent.dataTransfer.files);
});

.full-drop-zone {
  display: block;
  position: absolute;
  left: 20px;
  top: 20px;
  right: 20px;
  bottom: 20px;
  border: 2px dashed rgba(0,0,0,.3);
  border-radius: 20px;
  text-align: center;
  z-index: 20;
  background: rgba(255,255,255,0.7);
  color: rgba(0,0,0,.3);
  font-size: 20px;

  &.drop-over {
    border-color: rgba(0,0,0,0.5);
    color: rgba(0,0,0,0.5);
  }

  .description-wrapper {
    position: relative;
    width: 100%;
    height: 100%;
  }

  .description {
    position: absolute;
    left: 50%;
    top: 50%;
    max-width: 100%;
    max-height: 100%;
    text-align: center;
    -ms-transform: translateX(-50%) translateY(-50%);
    transform: translateX(-50%) translateY(-50%);
  }
}
