repr works quite well, and I've used it with lots of different
javascript... However I'm not completely confident in it as it fails
for unicode.
eg.
>>> a = u'a=\'asdfd\';\n\r\n'
>>> a
u"a='asdfd';\n\r\n"
>>> print repr(a)
u"a='asdfd';\n\r\n"
This is an invalid js string. eek. So first we need to translate it
to the correct charset encoding for the document. However js and
python encoding of unicode in strings is different too.
Here is one below which kind of works for js unicode stuff. But not
correctly, and the output isn't the best(too many backslashes), and it
isn't the fastest.
def encode_js(text, charset = None):
if type(text)==type(u""):
text= text.encode([charset, 'utf-8'][charset==None])
text = text.replace("\r", "\\r").replace("\n", "\\n")
text = text.replace('"', '\\"').replace("'", "\\'")
return "'" + text + "'"
This would be a good function to get right. We need the
specifications, as well as unittests first :)
