how do i pass js string variable to php without losing newlines and spaces?

i have a javascript variable which contains a string with new lines and spaces e.g "a \n d" i want to pass this to php without losing any spaces or new lines. currently i am using this:

my_window = window.open("", "ChemEdit Molfile", "status=1,width=550,height=350");    
urlString = "/chemedit/b.php?var=" +r;
my_window.location = urlString;

where r is the string i pass.

but if i do this in php 

echo $_GET["var"];

i just get it on one line with the spaces gone

please help

if you're going to pass newline and spaces in an url, you have to abide by the character rules of url strings, in which spaces must be represented as '%20' and newlines '\n" is '%5Cn'. the answers above will probably do this automatically, but if you find you ever need to manually encode or adjust, here is a reference for all special ascii characters that should be converted for passing through an http header request: http://www.w3schools.com/tags/ref_urlencode.asp

You need to encode the string, you can use encodeURIcomponent() for that.

I am not sure but try using encodeURIComponent function:

my_window.location = encodeURIComponent(urlString);
