why do both lines of code work?!

[Geoff Cox]

Hello,

I have 2 lines of code which are different but both work. I refer to
the 3rd line with the url in it. In the first case the // are not
escaped, in the second they are.

Either

soundManager.cr eateSound({
id:'mySound'+t,
url:'http://www.site.com/files/Track' + (+t+35) + '.mp3',
onfinish:functi on(){document.g etElementById(' test'+t+1).clas sName =
'visibleDiv2'} });
soundManager.pl ay('mySound'+t) ;
count++;

Or

soundManager.cr eateSound({
id:'mySound'+t,
url:'http:\/\/www.site.com/files/Track' + (+t+35) + '.mp3',
onfinish:functi on(){document.g etElementById(' test'+t+1).clas sName =
'visibleDiv2'} });
soundManager.pl ay('mySound'+t) ;
count++;

The only difference as far as I can see is that with the

url:'http://www.site.com/files/Track' + (+t+35) + '.mp3',

the part after http: to the end of the line is grayed out with
Homesite (my html editor) whereas with

url:'http:\/\/www.site.com/files/Track' + (+t+35) + '.mp3',

it is not.

Is there any other difference?! I am used to the idea of escaping
various characters but usually the "\" is required for the code to
work.

Cheers

No. / don't need to be escaped. You can, however - as you noticed it
won't have any effect, except worsening the readability. Masking is
needed though, when working with regular expressions.
