Re: [Dynapi-Help] FileReader, init function, and advice

[Raymond I. <xw...@ya...>]

The FileReader is basically for opening files on the
server without any server-side scripting.

The init function is called once the filereader object
has been initialized. This is because it can use
either the XMLHttp object or a Java Applet. Applets
can only be accessed after the page has been loaded.

As for what object to use for your page I would have
to say it depends. Both objects have their advantages
and disadvantages. The FileReader is mainly for
reading files (or pages) from the server in a
synchronous form.
