DESCRIPTION
Mojolicious::Plugin::TagHelpers is a collection of HTML tag helpers for Mojolicious.
Most form helpers can automatically pick up previous input values and will show them as default. You can also use "param" in Mojolicious::Plugin::DefaultHelpers to set them manually and let necessary attributes always be generated automatically.
% param country => 'germany' unless param 'country';
<%= radio_button country => 'germany' %> Germany
<%= radio_button country => 'france' %> France
<%= radio_button country => 'uk' %> UK
|
This is a core plugin, that means it is always enabled and its code a good example for learning how to build new plugins, you're welcome to fork it.
