我需要以编程方式更改maxFiles选项.这是我的初始:

  Dropzone.options.dropzone = {
                    paramName: "files",
                    params:true,
                    url: "/upload.php",
                    autoProcessQueue: true,
                    uploadMultiple: true,
                    parallelUploads: 10,
                    maxFiles: fileleft,
                    previewsContainer: ".dropzone",
                    clickable: true,
                    addRemoveLinks: false,
                    acceptedFiles: '.jpg,.pdf,.png,.bmp',                        
                    dictInvalidFileType: 'Unsupported.',
                    accept: function(file, done) { 
                        done();

                    },
                    init: function() {

                        var myDropzone = this;

                        this.on("successmultiple", function(files, response) {
                            ins.pop_gallery(id);
                            this.removeAllFiles(); 

                        this.on("maxfilesexceeded", function(file){

                            this.removeFile(file);
                        });

                        this.on("sending", function(file, xhr, formData) {
                            formData.append("custom", id );

                        });
                    }

                }   

一切正常,但我需要稍后更改maxFiles选项值.

我试过这个:

Dropzone.options.dropzone.maxFiles = fileleft;

还有这个:

myDropzone.maxFiles = fileleft;

但尽管有这个代码

alert(Dropzone.options.dropzone.maxFiles);

给我正确答案,maxFiles上传限制实际上仍然没有变化.

任何想法？

谢谢.
