如何计算在dropzone中上传的所有文件大小? [英] How to calculate all files size uploaded in dropzone?

问题描述

我想计算在dropzone中上传的所有选定文件的总大小.

I wanted to calculate all selected files total size uploaded in dropzone.

例如:如果我选择了5个文件，每个文件的大小为2mb，则 它应该返回10mb的总大小

Ex : if I selected 5 files each of size 2mb then it should return 10mb total size

我想限制所有文件的总大小是否超过限制.

I wanted to restrict if total size of all files is greater than limit.

有人可以帮我这个忙吗?

Can anyone please help me in this I am really stucked.

推荐答案

首先成功上传文件，然后遍历文件并获取文件大小. 如果总数超过一定限制，则可以在放置区上调用disable().

First get files uploaded successfully, then iterate through them and get size. You can then call disable() on the dropzone if the total exceeds a certain limit.

var files = dropzoneElement.getFilesWithStatus(Dropzone.SUCCESS), total=0;
$.each(files, function(file){
   total+=file.size;
});
alert(total);
