§ The attribute reference Expression

Attribute references get and set HTML attributes on elements. The form is @<name> for the attribute itself, or @<name>='<value>' to specify a value for commands like add and toggle.

§ Examples

<button _="on click add @disabled">Disable Me!</button>

<button _="on click remove @disabled">Enable Me!</button>

<button type="button" _="on click add @type='submit'">Change My Type!</button>

<button type="button" _="on click set my @type to 'submit'">Change My Type As Well!</button>

Attribute references can be read with the possessive or of form:

set x to my @data-x
set x to the @data-x of #other

§ Syntax

@<name>[='<value>']
