推荐答案

你好，

只能通过纯JavaScript和客户端无法找到文件的大小，无论是图像还是其他任何东西.现代浏览器不允许访问客户端PC上的物理文件，实际上，它们甚至不允许您的脚本知道真实路径.但是，您可以使用少量的Ajax和JQuery File Upload插件(例如 BlueImp [^ ]或 Uploadify [ ^ ].

问候

Hello,

There is no way to find out the size of a file be it a image or anything via pure javascript and client side only. Modern browser won''t allow access to the physical file residing on client''s PC, In fact they won''t even allow your script to know the real path. However you may be able to do this using little Ajax and JQuery File Upload plugin such as BlueImp[^] or Uploadify[^].
