JavaScript Help

[Mr_Bean]

Hello guys,

For one of my assignments I have to write an epub readed in JavaScript and I have no idea where to start. The reason is that we have only had 1 JavaScript lecture where they just covered the basics.

If anyone could help me with simply reading from a file in JavaScript, or perhaps point me to a good tutorial that could help me, that would be awesome. I mainly need help with accessing all files in a specific folder.

I have been Googling a lot, but they don't help with accessing multiple files in a folder, just with manually selecting files with a dialog.

This is quite urgent and any help will be appreciated.

Thanks,

Mr_Bean

I'm too lazy to actually read it, but try starting here: http://nodejs.org/docs/v0.4.8/api/fs.html#file_System
Note that File I/O is unlikely to be allowed for in-browser use due to security and shit.

 

[Mr_Bean]

Thanks, will take a look at that.

EDIT: Could someone please explain what is going on here:

r.onload = (     // r is a variable containing a FileReader
    function (f) {
        return function (e) {
            var contents = e.target.result;
            alert(contents);
        };
    })(f);

I'm not even sure how to indent that properly :/

I don't actually know anything about javascript, so I can't help you much. Cept by bumping the thread.

 

[Mr_Bean]

Please can someone explain what is happening here.
It is really urgent.

 

[Zakamutt]

Why don't you tell whomever gave you the assignment about your situation?

 

[Mr_Bean]

I have sent 2 emails but no reply...
They have taught us basically nothing and expect us to do this huge assignment.
Starting to get irritated with this now ;(

 

[Zakamutt]

Well if you're not getting help here, stackoverflow might be the place to go. Not sure though, your question isn't that generic

 

[Mr_Bean]

All that I need is for someone to explain what the above code does.
From there I should be fine.

I would explain it to you now but I'm kind of in a hurry. You should ask your question here. Hope the website helps you.

 

[Mr_Bean]

Don't worry, I think I've figured it out by myself.

 

[WindowsVistaSucks]

I just got back. But alright, good to know you've figured it out.
