# A utility method for escaping HTML entities in JSON strings.
|
||||
# This method is also aliased as <tt>j</tt>.
|
||||
#
|
||||
# Note that after this operation is performed the output is not
|
||||
# a valid JSON.
|
||||
#
|
||||
# In your ERb templates, use this method to escape any HTML entities:
|
||||
# <%=j @person.to_json %>
|
||||
#
|
||||
# ==== Example:
|
||||
# puts json_escape("{\"name\":\"john\",\"created_at\":\"2010-04-28T01:39:31Z\",\"id\":1}")
|
||||
# # => {name:john,created_at:2010-04-28T01:39:31Z,id:1}
|
||||
#
|
||||
# puts json_escape("is a > 0 & a < 10?")
|
||||
# # => is a \u003E 0 \u0026 a \u003C 10?
