The read-only DataTransferItem.type property returns the type (format) of the DataTransferItem object representing the drag data item. The type is a Unicode string generally given by a MIME type, although a MIME type is not required.

Some example types are: text/plain and text/html.



Return value

A DOMString representing the drag data item's type.


This example shows the use of the type property.

function drop_handler(ev) {
 var data = ev.dataTransfer.items;
 for (var i = 0; i < data.length; i += 1) {
   if ((data[i].kind == 'string') &&
       (data[i].type.match('^text/plain'))) {
     // This item is the target node
     data[i].getAsString(function (s){;
   } else if ((data[i].kind == 'string') &&
              (data[i].type.match('^text/html'))) {
     // Drag data item is HTML
     console.log("... Drop: HTML");
   } else if ((data[i].kind == 'string') &&
              (data[i].type.match('^text/uri-list'))) {
     // Drag data item is URI
     console.log("... Drop: URI");
   } else if ((data[i].kind == 'file') &&
              (data[i].type.match('^image/'))) {
     // Drag data item is an image file
     var f = data[i].getAsFile();
     console.log("... Drop: File ");
