Javascript File i/o

Thursday May 25th, 2000

Pete Collins from Alphanumerica and Mozilla developers have created a Javascript interface for doing file i/o in Mozilla, which will allow new Mozilla components like Alphanumerica's Crash Recovery system to function properly.

Patterned after the PHP filesystem functions, simple functions such as file read/write and directory create are supported. The code has not yet made it into the nightly build, but they expect it will get in soon.

Note from AN: There seems to be a misconception about Javascript File I/O being a security risk. It is important to clarify that this project is not opening any security holes in Mozilla. There is a difference between Javascript on the Internet and Javascript inside the application. Javascript is used inside Mozilla to create the functionality for the application. This is in contrast to any Javascript downloaded from the Internet that is used for functionality only inside a Web page. This project does not grant any access to Javascript found on the Internet. For more information about how Javascript is used inside Mozilla read more about XPCOM and XPConnect.

"First off, I'm pretty sure Skins can contain JavaScript (especially for custom button functionality)"

A custom button would require xul and js to make it work. That is known as a package I believe. A skin is just a .css file.

So if you use skins (only css files), you have nothing to worry about. If you install a package (I believe you have to run XPInstall... see the install for ChatZilla) then yes, there is the possability for virus' and other nasty things. But you do get an install dialog coming up when that happens.
