I have one textarea, one file browser control, and one load button. When the user selects a file and clicks the load button, I want to display the contents of the selected file in the textarea. I would like this solution to be designed in Javascript. It should work on Internet Explorer, FireFox, and Chrome.

"contentents in the textg"? Aha...
I'm even uncomfortable about asking the usual "what have you done so far?" or "what's the problem?"... :-)

I'm pretty sure this cannot be done with JavaScript without the data traveling to the server first. However, you can have it travel to the server using AJAX. See here: http://stackoverflow.com/questions/527955/how-can-i-upload-a-file-using-javascript-without-a-postback

Alternatively, you can use Flash and Java (note: not JavaScript) to perform the upload entirely on the client.

I just noticed the question was tagged as JSP and not ASP.NET. Assuming JSP can handle AJAX, the principle should be the same. That is, can't do it entirely on the client (the server will have to be involved), unless Java (on the client side) or Flash are used.
