Im using the dropzone js (http://www.dropzonejs.com/) to upload files but I need to know how many files are currently inside the Dropzone, the user might have deleted some but I need to know if there is at least 1 file before I submit the whole form that the user is filling.
If i use the myDropzone.length it will still count the removed files from the dropzone so if the user adds 2 files and then removes one of them the .length would be = 2 and in that case I would need to know the real length which would be 1 in this particular case
Dropzone provide multiple function to get only accepted, rejected, queued or uploading files.
// To access only accepted files count (answer of question)
myDropzone.getAcceptedFiles().length
// To access all files count
myDropzone.files.length
// To access all rejected files count
myDropzone.getRejectedFiles().length
// To access all queued files count
myDropzone.getQueuedFiles().length
// To access all uploading files count
myDropzone.getUploadingFiles().length
"To access all files in the dropzone, use myDropzone.files
."
