Template::Plugin::JSON::Escape(3pm) User Contributed Perl Documentation Template::Plugin::JSON::Escape(3pm) NAME
Template::Plugin::JSON::Escape - Adds a .json vmethod and a json filter. SYNOPSIS
[% USE JSON.Escape( pretty => 1 ) %]; <script type="text/javascript"> var foo = [% foo.json %]; var bar = [% json_string | json %] </script> or read in JSON [% USE JSON.Escape %] [% data = JSON.Escape.json_decode(json) %] [% data.thing %] DESCRIPTION
This plugin allows you to embed JSON strings in HTML. In the output, special characters such as "<" and "&" are escaped as "uxxxx" to prevent XSS attacks. It also provides decoding function to keep compatibility with Template::Plugin::JSON. FEATURES
USE JSON.Escape Any options on the USE line are passed through to the JSON object, much like "to_json" in JSON. json vmethod A ".json" vmethod converts scalars, arrays and hashes into corresponding JSON strings. [% json_stuct = { foo => 42, bar => [ 1, 2, 3 ] } %] <script> var json = [% json_struct.json %]; </script> <span onclick="doSomething([% json_struct.json %]);"> json filter A "json" filter escapes "<", ">", "&", "+", "U+2028" and "U+2029" as "uxxxx". In the attribute, you may just use an "html" filter. [% json_string = '{ "foo": 42, "bar": [ 1, 2, 3 ] }' %] <script> var json = [% json_string | json %]; </script> <span onclick="doSomething([% json_string | html %]);"> json_decode method A "json_decode" method allow you to convert from a JSON string into a corresponding data structure. [% SET json_struct = JSON.Escape.json_decode(json_string) %] [% json_struct.foo | html %] SEE ALSO
