What's the effect of newline in javascript?

[roarde]

I lost a neat widget provided by my isp after they did a page edit. Turns out the tool they used reformatted the text and added a newline in the middle of the widget's window open definition. "Javascript" is defined:

Code:

<script type="text/javascript">

The error(?) is here:

Code:

function opensessionwin(whichone) {
remote =
window.open("","sessionwin","width=240,height=400,toolbar=0,location=0,directories=0,status=0,menubar=0[EXTRA NEWLINE HERE]
,scrollbars=1,resizable=1");

Question is, is newline in code supposed to be ignored as in html, or is it interpreted as, say, bash would? (BTW, "{" is matched by "}" at end of declaration.)

Not interested in writing js myself, but don't want to send in an erroneous fix request.

thank you

Just whipped this off to a friend who does java  programming for a living. Should hear back shortly.

Buddy says it looks like it's a "reminder" for additional code to be added later. The brackets would break the app and prevent it from running properly.

Thanks, retired1af. They may indeed have wished to disable it. It gives session length, remaining, etc., and sometimes conficts with the figures given by their support personnel.

Does leave me wondering how js knows the beginning and end of a declaration, tho.

Just re-read. Your java-programming buddy knew it's javascript, right?

Yepper.

I'll have to try for clarity one more time.

[EXTRA NEWLINE HERE] (including "[" and "]") was inserted by me in hopes of better pointing out the "extra" newline. "[]" being notation for "inserted by editor", I used it. Seems I'm speaking English when I should be speaking code.

So, was it "{}" (the original) or "[]" (my insertion) that broke the code.

I'd still like to know what newline (or may be win CRLF) does in js code.

Thanks again.

Square brackets are used to reference objects. Even with my limited abilities in writing code, what is between those brackets (INSERT NEWLINE HERE) is not an object. To insert a new line in javascript, \n is used.

If the author is attempting to insert a comment, using square  brackets isn't the way to go as they definitely have a use within javascript, and adding comments isn't one of those uses.
