Question

I am using dropzone.js. I want to implement the \"Copy & Paste\" feature in it.

What I tried is:

Answer 1

If you don't want to use other JS libraries, you can integrate dropzone with a paste event fairly easily by retrieving the data as a file from the paste event:

// create dropzone however you wish
var myDropzone = new Dropzone("div#element", { url: "/path/to/upload"});
// add paste event listener to the page
document.onpaste = function(event){
  var items = (event.clipboardData || event.originalEvent.clipboardData).items;
  for (index in items) {
    var item = items[index];
    if (item.kind === 'file') {
      // adds the file to your dropzone instance
      myDropzone.addFile(item.getAsFile())
    }
  }
}

Answer 2

var myDropzone = new Dropzone(".dropzone", { });

document.onpaste = function(event){
  var items = (event.clipboardData || event.originalEvent.clipboardData).items;
  for (index in items) {
    var item = items[index];
    if (item.kind === 'file') {
      // adds the file to your dropzone instance
      myDropzone.addFile(item.getAsFile())
    }
  }
}

Just add this code. Do not declare URL because URL also declared in PHP or coding file, paste this code in view file (HTML, PHP, etc).

This worked for me. It uses the FileReaderJS wrapper. As I am not creating the dropzone programatically, I had to store it at runtime with the init() method.

See here for the FileReaderJS part.

var myDropzone;

function checkUploadFile(filename) {
    //do some input checking here, if you want
    return true;
}

Dropzone.options.FileDropUploadZone = {
  paramName: "myDiv",
  maxFilesize: 3, // MB
  uploadMultiple: true,
  addRemoveLinks: true,
  acceptedFiles: 'image/*',
  maxFiles: 10,
  accept: function(file, done) {
      if (!checkUploadFile(file.name)) {

                done('Invalid file');
                myDropzone.removeFile(file);

      }
      else { done(); }
  },
  init: function() {
      myDropzone = this;
  }
};

$(document).ready(function () {
        FileReaderJS.setupClipboard(document.body, {
            accept: {
                'image/*': 'DataURL'
            },
            on: {
                load: function(e, file) {
                myDropzone.addFile(file);
                }
            }
        });
});
