如何将服务器上的现有文件添加到 dropzone 中，同时正确使用所有功能和正确的样式？

Answer 1

我写了一个添加文件的函数：addCustomFile(file, thumbnail_url , responce)

技术支持版本：4.0.1 稳定

正确工作：maxFiles 限制、事件 maxfilesexceeded、事件成功和其他

$("#dropzone-images").dropzone({
    url: "...",
    paramName: 'image_temp',
    maxFiles: 1,
    init: function () {
        this.addCustomFile = function(file, thumbnail_url , responce){
            // Push file to collection
            this.files.push(file);
            // Emulate event to create interface
            this.emit("addedfile", file);
            // Add thumbnail url
            this.emit("thumbnail", file, thumbnail_url);
            // Add status processing to file
            this.emit("processing", file);
            // Add status success to file AND RUN EVENT success from responce
            this.emit("success", file, responce , false);
            // Add status complete to file
            this.emit("complete", file);
        }

        this.addCustomFile(
            // File options
            {
                // flag: processing is complete
                processing: true,
                // flag: file is accepted (for limiting maxFiles)
                accepted: true,
                // name of file on page
                name: "The name",
                // image size
                size: 12345,
                // image type
                type: 'image/jpeg',
                // flag: status upload
                status: Dropzone.SUCCESS
            },
            // Thumbnail url
            "http://.../img.jpg",
            // Custom responce for event success
            {
                status: "success"
            }
        );
    }
});
