Question

How do i define an textarea as required with mojolicious tag helper?

I need to generate a textarea like this

<textarea name="comment" required></textarea>

When trying to do the same with tag helper

%= text_area 'comment', 'required'

I get

<textarea name="comment">required</textarea>

Mojo tag helpers will simply pass extra attributes through (see sub _tag in the source).

In HTML5, an empty attribute can be declared as attr="" (docs here).

So, based on the Mojo text_area docs, the syntax would be:

%= text_area 'comment', required => ''

According to the HTML5 spec they are the same. I am not aware of any way to create empty attributes in mojo. Best. – codnodder Dec 25 '13 at 18:47
You are right www.w3.org/TR/html5/infrastructure.html#boolean-attribute. If the attribute is present, its value must either be the empty string or a value that is an ASCII case-insensitive match for the attribute's canonical name, with no leading or trailing whitespace – David Michael Gang Dec 26 '13 at 07:25

I looked in the hrml5 spec and it does not look like a valid option www.w3.org/TR/html5/infrastructure.html#boolean-attribute. If the attribute is present, its value must either be the empty string or a value that is an ASCII case-insensitive match for the attribute's canonical name, with no leading or trailing whitespace, so 1 is not valid but required => 'required' is one – David Michael Gang Dec 26 '13 at 07:27
