 在上传成功时，dropzone会在div中使用类dz-success添加已上传元素的预览，如果存在该元素，则可以检查每个表单，一种方法可以使用jQuery的函数： 
 
function checkForm() {
  var valid = true;
  if ($.trim($('input[name=your_name]').val()) === '') {
    valid = false;
  }
  $('form.dropzone').each(function() {
    if ($(this).find('.dz-success').length === 0) {
      valid = false;
    }
  });
  if (valid) {
    $('button[disabled=True]').removeAttr('disabled');
  }
};
 
 然后在dropzone表单的初始化中，您可以在成功事件上添加一个事件侦听器，该事件调用函数来检查init选项中的表单，当您手动初始化dropzone时，需要将auto discover选项设置为false。 
 
 init 文档 ： 
 
 
 
 是Dropzone初始化时调用的函数。 您可以在此函数中设置事件侦听器。 
 
 
 根据文档 ， success事件在以下情况下触发： 
 
 
 
 该文件已成功上传。 获取服务器响应作为第二个参数。 （此事件之前被称为完成） 
 
 
Dropzone.autoDiscover = false;
$(".dropzone").each( function(){
    $(this).dropzone({
        init: function() {
            this.on("success", function() { 
                checkForm();
            });
        }
    });
});
 
 您还可以通过将验证功能添加到完整选项来调用验证功能。 
 
 根据文件 ： 
 
 
 
 上传成功或错误时调用Complete。 
 
 
Dropzone.autoDiscover = false;
$(".dropzone").each(function() {
  $(this).dropzone({
    complete: function(file) {
      if (file.status == "success") {
        checkForm();
      }
    }
  });
});

On upload success dropzone adds the preview of the uploaded element inside a div with the class dz-success, you can check for every form if exists that element, one way can be with a function using jQuery:
 
function checkForm() {
  var valid = true;
  if ($.trim($('input[name=your_name]').val()) === '') {
    valid = false;
  }
  $('form.dropzone').each(function() {
    if ($(this).find('.dz-success').length === 0) {
      valid = false;
    }
  });
  if (valid) {
    $('button[disabled=True]').removeAttr('disabled');
  }
};
 
Then on the initialization of the dropzone form you can add an event listener on the success event that calls the function to check the form in the init option, when you initialize dropzone manually you need to set auto discover option to false.
 
init documentation:
 
 
 
is a function that gets called when Dropzone is initialized. You can setup event listeners inside this function.
 
 
According to the documentation the success event is triggered when:
 
 
 
The file has been uploaded successfully. Gets the server response as second argument. (This event was called finished previously)
 
 
Dropzone.autoDiscover = false;
$(".dropzone").each( function(){
    $(this).dropzone({
        init: function() {
            this.on("success", function() { 
                checkForm();
            });
        }
    });
});
 
You also can call the validation function by adding it to the complete option.
 
According to the documentation:
 
 
 
Complete is called when the upload was either successful or erroneous.
 
 
Dropzone.autoDiscover = false;
$(".dropzone").each(function() {
  $(this).dropzone({
    complete: function(file) {
      if (file.status == "success") {
        checkForm();
      }
    }
  });
});
