line break character in javascript

[Matt]

What is the syntax for line break character in javascript?? For example, the
following code will yield error "
unterminated string constant." If I put the following in one line, then no
error.

window.showModalDialog("page2.html",
document,"menubar=no, titlebar=no, toolbar=no, location=no,
directories=no, status=no, menubar=no,scrollbars=yes, resizable=no,
copyhistory=yes, width=400, height=500");


Please advise. thanks!!

Placing a line break in that string might cause problems anyway. What
you're looking for is a way to concatenate strings so you can spread them
across multiple lines. Use:

myFunction( 'first part of a string' +
'second part of a string' );

That would be the same as passing

'first part of a stringsecond part of a string'

to the function (no space between 'string' and 'second' is intentional).

However, you can actually shorten that string; boolean values can be
omitted if false. It is their default value. You could write:

window.showModalDialog('page2.html', document,
'scrollbars,copyhistory,resizable,width=400,height=500');

Note that you can also omit '=yes', and that I removed the spaces. The
former isn't necessary, and the latter isn't allowed. Finally, notice that
I included resizable: you shouldn't prevent the user from resizing the
page - it is their browser, not yours.
