You need to create an AjaxAppender. It's covered in the documentation of log4javascript (for example, in the quick start tutorial: http://log4javascript.org/docs/quickstart.html).

var log = log4javascript.getLogger("server");
var ajaxAppender = new log4javascript.AjaxAppender("/yourapp/jslog.do");
log.addAppender(ajaxAppender);

log.debug("Testing server log");
