I want user upon clicking a button it will load the a txt file from a eg Desktop and display the contents.
Can this be done?
I found a lot of examples for loading a file but not displaying it.
JavaScript in the browser can't access the user's file system - it would be a security issue.
Additionally, check out this SO question - the File API will allow this.
There's an excellent tutorial on html5rocks.com, 'Reading Files in JavaScript using the File APIs', that shows how to use the FileReader interface:
