I am trying to make a JS program using a text file on the client side. The thing is that it was difficult to find out how to do such a basic functionality because it is not a desired feature. I want to open a text file which is not in the local directory of a user but in the directory with the html file. So, what I want is the JS version of this code (which is in python)

# Open a file
fo = open("foo.txt", "wb")
fo.write( "Python is a great language.\nYeah its great!!\n");

# Close opend file
fo.close()

Thanks!

You can read a file with FileReader() (as a result of a user selecting files) but fortunately we can't modify client's or server's files with JavaScript in client side (there is no FileWriter()). To do that, you should upload the file to the server (through Ajax or a simple html form) and modify it with server side code.
