NAME

Template::Flute::Filter::JsonVar - JSON to Javascript variable filter

DESCRIPTION

Takes a Perl structure or a JSON string and returns Javascript which parses the JSON string with Jquery and assigns it to the variable json.

The following example shows you how to inject the JSON variable into the template:

HTML Template:

    <script type="text/javascript" id="vars"></script>

XML Specification:

    <value name="jsvars" id="vars" filter="json_var"/>

Values for Template::Flute:

    Template::Flute->new(...,
        values => {jsvars =>
          {username => 'shopper@nitesi.biz', city => 'Vienna'},
        },
    );

This results in the following JavaScript:

    <script type="text/javascript" id="vars">
    var json = $.parseJSON('{"city":"Vienna","username":"shopper@nitesi.biz"}');
    </script>
