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'},

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