怎么使用dropzone手动上传？

Question

使用dropdone手动上传，代码按照官方的例子写的，但是按钮那里没有事件，求大神解答

<form action="http://164197625.tunnel.2bdata.com/struts2-upload/uploadList" class="ui dropzone form" id="my-awesome-dropzone"
                method="post" id="nameform" id="myDropzone">
                <div class="fallback">
                    <input id="price" name="upload" type="file" multiple />
                </div>
                </form>
                <button id="submit-all">Submit all files</button>
 

js代码

 Dropzone.options.myDropzone = {


            autoProcessQueue: false,

            init: function () {
                var submitButton = document.querySelector("#submit-all")
                myDropzone = this;

                submitButton.addEventListener("click", function () {
                    myDropzone.processQueue();
                    alert(1);
                });


                this.on("addedfile", function () {
                    $("#submit-all").removeAttr("disabled");
                });

            }
        };
