Topic awaiting preservation: Multine innerhtml (Page 1 of 1)

Is there a escape sequence for multiline statements (I'm want to put a couple of tables using document.getElementById(id.innerHTML but i dont want to do it all in the same line

Well, you can do this:

document.getElementById(id).innerHTML = "blah blah blah"
+ "blah blah blah"
+ "blah blah blah";

there's no one-statement-per-line restriction. You just can't let the quotes themselves span the newline character.

Thanks

I think I'll take this opportunity to warn those of you who like to ignore semi-colons in your code. This is a rare possibility, but it can happen. Suppose you wrote this code:

a=b+c
(a==d)?func1():func2()

This two line code will likely cause an error. 100 points to anyone who can say why.

I suppose if the browser ignores the line break it might try to multiply c with either true or false, or maybe with one of the function names. Do I win?

Right idea, but not exactly correct; you get partial credit =)

You don't have paretheses around the conditional statement so the 1st statement gets included as part of the condition.

I think you've basically got it. The problem is, since there are no semicolons, the interpreter (the browser running the javascript) is forced to put them in itself. The rules for automatic semicolon insertion are:

1. if leaving the semicolon out at the end of the line would cause a syntax error, put one in.
2. otherwise, if it's possible to understand the code without inserting a semicolon, don't.

So the interpreter sees the two statements as this:

a=b+c(a==d)?func1():func2()

And it looks for a function named "c". That function probably doesn't exist, so an error is thrown. (Note that it's not a *syntax* error, because the syntax itself makes sense. That's why a semicolon wasn't inserted.)
