Here's a simple example of getting the size of a file before uploading. It's using jQuery to detect whenever the contents are added or changed, but you can still get
files[0].size
without using jQuery.Here's a more complete example, some proof of concept code to Drag and Drop files into FormData and upload via POST to a server. It includes a simple check for file size.

After take time exploring around, I finally found the answer. This is my code to get file attach with jQuery:
This is just the example code for getting the file size. If you want do other stuffs, feel free to change the code to satisfy your needs.

Browsers with HTML5 support has files property for input type. Font real madrid 2013. This will of course not work in older IE versions.

ucefkh's solution worked best, but because $.browser was deprecated in jQuery 1.91, had to change to use navigator.userAgent:

you need to do an ajax HEAD request to get the filesize. with jquery it's something like this

Please do not use
ActiveX
as chances are that it will display a scary warning message in Internet Explorer and scare your users away. If anyone wants to implement this check, they should only rely on the FileList object available in modern browsers and rely on server side checks only for older browsers (progressive enhancement).

You can use PHP filesize function. During upload using ajax, please check the filesize first by making a request an ajax request to php script that checks the filesize and return the value.

You can by using HTML5 File API: http://www.html5rocks.com/en/tutorials/file/dndfiles/
However you should always have a fallback for PHP (or any other backend language you use) for older browsers.

Personally, I would say Web World's answer is the best today, given HTML standards. If you need to support IE < 10, you will need to use some form of ActiveX. I would avoid the recommendations that involve coding against Scripting.FileSystemObject, or instantiating ActiveX directly.
In this case, I have had success using 3rd party JS libraries such as plupload which can be configured to use HTML5 apis or Flash/Silverlight controls to backfill browsers that don't support those. Plupload has a client side API for checking file size that works in IE < 10.

Input Type File Accept
feof(fid) only ever becomes true when there is no input remaining _and_ a read operation then attempts to read input that is not there. feof() does not look forward to see whether there is more input or not: it just reports on whether the eof flag has been set already by a read operation on an empty buffer having tried and failed to get input. If you had the case where, for example, you had a file that ended in XYZPDQ with no end-of-line indicator, then when a read operation got to that line, it would read the data that is there but *not* set the end-of-line indicator (in this case the buffer was not empty), and feof would not report true until the *next* read attempt found the buffer empty and nothing more to fetch.
