We should add logic if user drop the file outside the drop zone, nothing would happen. The browser default behavior is to open these files. When user drag the files, we do not want user to drop the files outside the dropzone we defined. Once the files validation passed, display all the file details and Upload button for user to confirm and upload.Go through the collection to make sure the file type is what you expected, the file size does not exceed your maximum allowed size, etc.Call pereventDefault() function to prevent browser default behavior for the file drop (opening the file).Inside the drop event, we need to do following things: Each file object has following properties: This property contains an array of File object. In this event handler, we can trigger the “File Open Dialog” programmatically so user can select files without drag and drop.Īs previously mentioned, the drop event has files inside property. click event: This event fires when user click in any area inside the drop zone.We can remove the drop zone style changes we did in the dragover event handler.
