This code for some reason writes an error Uncaught Syntax Error: Unexpected token : What can be wrong?

the result that is returned when executing http://vkontakte.ru/feed2.php should be in JS format, in this case instead of

 {"user":{"id":7594127},"friends":{"count":0},"messages":{"count":0},"events":{"count":0},"groups":{"count":0},"photos":{"count":0},"videos":{"count":0},"notes":{"count":0},"gifts":{"count":0},"lang":{"id":"0","p_id":0},"activity":{"hash":"d41d8cd98f00b204e9800998ecf8427e"}}

should be displayed

 document.write(' {"user":{"id":7594127},"friends":{"count":0},"messages":{"count":0},"events":{"count":0},"groups":{"count":0},"photos":{"count":0},"videos":{"count":0},"notes":{"count":0},"gifts":{"count":0},"lang":{"id":"0","p_id":0},"activity":{"hash":"d41d8cd98f00b204e9800998ecf8427e"}} ')
