hast utility to get the state of a <menu> element.

Install

npm:

npm install hast-util-menu-state

Use

var menuState = require('hast-util-menu-state')

// If there’s no last element or that node is not a `menu`:
menuState([{type: 'element', tagName: 'a'}]) // => null

// If the last node is a `menu` without `type`:
menuState([{type: 'element', tagName: 'menu'}]) // => 'toolbar'

// If the last node is a `menu` with a `type`, or that node has
// a parent `menu` with a type:
menuState([
  {type: 'element', tagName: 'menu', properties: {type: 'context'}},
  {type: 'element', tagName: 'li'},
  {type: 'element', tagName: 'menu'}
]) // => 'context'

API

Get the state of a <menu> element. The state is calculated from the lowest <menu> with a valid type property. If no <menu> has a type, it defaults to 'toolbar'.

The algorithm stops looking for higher <menu>s if a template element, or non-element, is found.

Parameters
Returns

string? — either 'context' or 'toolbar' (the state the menu is in), or null, if the last node is not a menu element.

Security

hast-util-menu-state does not change the syntax tree so there are no openings for cross-site scripting (XSS) attacks.
