Topic awaiting preservation: JavaScript != JScript ? (Page 1 of 1)

I just recently found out that Javascript and Jscript are not the same thing...?

Apparently, JScript is "Micro$oft's version" of Javascript.
Funny, because I had been using the terms interchangably until now.

What I'd like to know is: are there any specific differences in the actual language? And which one am I supposed to use?

(I googled this and only found a few pages stating that JScript is different, providing no details.)

Yeah, Jscript is MS's version of JavaScript, but they're really very similar. Jscript has extra, IE-only features. It's best to say "JavaScript," in my opinion, since that's the original, but it doesn't really matter.

IE-only features such as...?

Such as document.all, for instance.

and like the functions allowing the manipulation of files offline. Sorry I don't have the JScript documentation but I've seen some kind of File Explorer done in JScript with those functions.

Ahhhhh...

Yes, those sites that try to sell you security software by claiming they can see inside your hard drive. Hehehe.


Thanks guys, for clearing that up.

Doh!


You're right. I got confused. Well either way, I think I get it now...

On another note...


I'm writing up a browser detection script and I'm wondering if there are any "official" browser names that have to be used in the navigator appname thingy. I mean what's the difference between say, "Internet Explorer" and "Microsoft Internet Explorer"? Will either one work? How about appnames for lesser known browsers?

Or is this all blatantly obvious?

Sorry. I'm clueless when it comes to JavaScript.

Perhaps this is of some interest then...

Cool script.
But ehr .... i really have no use for the information overload it generates.....

Wow.

What I hand in mind was a bit simpler, but thanks anyways.

I wrote a browser sniffer, too!

if (document.all)

*stabs Slime*

I obviously didn't write the above. I just thought it could be rather useful.

Is that available only for IE????
Hmmm......
Here is a story.
You know I am studying web stuff at polytechnic. I took a class of JavaScript and ActionScript. I made a script which was sort of css switcher. My tutor wrote document.all on the board. I cannot remember all the script but I am sure about that. Cuz I was wondering what the hell all was.
Thanks for telling me that, Slime. Otherwise I didnot know about this.
Cya.
