@Kurtis Rader
i'm sure the non-buildin type 'article' instance have 'title' attribute.The
'article' is dict like, so I always use article[0].title instead.
after format 'article[0]', information shown as below:
---
<!--Article(key=Key('Article', 5905064635924480),
title=u'mytitlestring tag', type=u'Translate')-->
---(use ' instead)
<!--Article(key=Key('Article', 5905064635924480), title=u'mysomestring',
type=u'Translate')-->
---
if i'm sure article[0] contains title property, as:article[0].title print
out 'mysomestring'.
For the non-buildin type, how to alert article[0].title in javascript?
@Markus Unterwaditzer
Did you say that I must use json to dumping the non-buildin type for jinja2?
if it is, I must redirect my focus to json way.
( but i think jinja2 could process alert("{{article[0].title}}"); in some
other way. )
