Run code

Answer 1

The error is caused by the fact that you are running the code in a script, and dropzone is trying to upload files to a URL that does not exist.

dropzone , , , html-.

, URL.

, .

var myDropzone = new Dropzone("#mydropzone", {
  url: "/file/post",
  acceptedFiles: accept,
  uploadMultiple: false,
  createImageThumbnails: false,
  addRemoveLinks: true,
  maxFiles: 3,
  maxfilesexceeded: function(file) {
    this.removeAllFiles();
    this.addFile(file);
  },
  init: function() {
    this.on('error', function(file, errorMessage) {
      if (errorMessage.indexOf('Error 404') !== -1) {
        var errorDisplay = document.querySelectorAll('[data-dz-errormessage]');
        errorDisplay[errorDisplay.length - 1].innerHTML = 'Error 404: The upload page was not found on the server';
      }
    });
  }
});

init: function() {
  this.on('error', function(file, errorMessage) {
    if (file.accepted) {
      var mypreview = document.getElementsByClassName('dz-error');
      mypreview = mypreview[mypreview.length - 1];
      mypreview.classList.toggle('dz-error');
      mypreview.classList.toggle('dz-success');
    }
  });
}
