MIME Type Validation

Validate files by MIME type using the onSelect callback. This demo only accepts image/* MIME types.

Drag & drop image files here

<div id="myUploader" class="mu-uploader">...</div>

var uploader = new MultipleUpload(document.getElementById('myUploader'), {
 uploadUrl: '/api/upload',
 onSelect: function(file) {
 if (!file.type || !file.type.startsWith('image/')) {
 document.getElementById('error').textContent =
 file.name + ' is not an image file.';
 return false;
 }
 return true;
 }
});
