If you use javascript code with Django-template filter or other related things, it will be not sufficient to qoute string in javascript. This filter escape the string and quote it.

import os
from django.template.defaultfilters import escape

@register.filter(name="tojavascript")
def tojavascript (value) :
	if len(value.split(os.linesep)) > 1 :
		__s = ["\"%s\"" % escape(i) for i in value.split(os.linesep)]
		return "%s\n%s" % (__s[0], "\n".join([" + %s" % i for i in __s[1:]]), )
	else :
		return "\"%s\"" % escape(value)

doesn't seem to work.

the code is also exceedingly unclear, perhaps you'd care to explain it a bit?
