I have a <div/> tag which contains a file upload <input id="file" type="file"/> tag. I want to post the contents of the input tag to a php page using $.ajax() or $.post() but how do I grab the contents of the input tag having its type as "file"? so I can submit it using the jQuery ajax functions?

Note: My code doesn't have a <form/> tag yet. I am not sure if its mandatory to upload files. Also i've seen some workarounds using <iframe> I want to know if this can be done otherwise.

I don't want to use any plugins to do this.

A byte stream can't be part of an asynchronous request.

In other words, you can't send data using AJAX approaches.

True. And I've answered that because he's thinking in jQuery $.ajax or any other approach using AJAX.
@MatíasFidemraizer: This is not true. You can catch the data using "drop" event listener (e.g. on div) using event.dataTransfer.files and then create new FormData using var fd = new FormData(); fd.append("fileToUpload", fileList[i]);, create new XMLHTTPRequest and send the data: request.send(fd);.
@Julian I guess you're talking about HTML5. Feel free to edit my answer adding this info and I'll approve the edit for you.
