在IE中上传文件之前，如何获取文件大小？

Question

I'm trying to get a file size before upload file in IE without ActiveX or like this.

I already read lots of questions and answers and they said it is impossible.

However, I found that Plupload which is jquery file upload library,

can get a file size in IE 7+ without AcviceX or Ajax submit to a server.

Have any clue to get a file size in IE7+ or how Plupload can get a file size?

Answer 1

<input type="file" id="myFile" />

$('#myFile').bind('change', function() {

  //this.files[0].size gets the size of your file.
  alert(this.files[0].size);

});

Try with Above Code
