jquery - How to check images are added in dropzone before posting ajax properly? -


i've attempted write script check if there images dropped on dropzone. i'm using twitter bootstrap.

the ajax script runs on submit is:

$.ajax({     type: method,     action: action,     data: formdata,     processdata: false,     contenttype: false,     datatype: 'json',     beforesend: function(xhr) {         if (mydropzone.getqueuedfiles().length == 0) {             // i've managed values of number of images dropped.             // want inform user they've not added images,             // can continue submit without adding images if click on continue on modal             // or click cancel , drop images.         }     },     success: function(data) {         console.log(data);     },     error: function(data) {         var errors = data.responsejson;             console.log(data);             $.each(errors, function(key, value) {                 $('#' + key).after('<div class="alert alert-danger">' + value + '</div>');             });     }  });

i'm not sure how achieve that. thank reading
