json_escape(s)
public
A utility method for escaping HTML entities in JSON strings using uXXXX JavaScript escape sequences for string literals:
json_escape("is a > 0 & a < 10?") # => is a \u003E 0 \u0026 a \u003C 10?
Note that after this operation is performed the output is not valid JSON. In particular double quotes are removed:
json_escape('{"name":"john","created_at":"2010-04-28T01:39:31Z","id":1}') # => {name:john,created_at:2010-04-28T01:39:31Z,id:1}
This method is also aliased as j, and available as a helper in Rails templates:
<%=j @person.to_json %>
