This class inherits a constructor from Dommy::Element

Instance Method Details

#__internal_instantiated_sheet__ ⇒ Object

The memoized sheet, or nil when none was created yet or the element's text changed since (stale sheet). Lets the cascade read CSSOM state only for sheets someone actually touched, without instantiating sheet objects for every <style> in the document.

# File 'lib/dommy/html_elements.rb', line 4589

def __internal_instantiated_sheet__
  @__sheet if @__sheet && @__sheet_text == text_content.to_s
end

#__js_get__(key) ⇒ Object

# File 'lib/dommy/html_elements.rb', line 4593

def __js_get__(key)
  case key
  when "disabled"
    disabled

    self.disabled = value

# File 'lib/dommy/html_elements.rb', line 4558

def disabled
  @__disabled == true
end

#disabled=(v) ⇒ Object

# File 'lib/dommy/html_elements.rb', line 4562

def disabled=(v)
  @__disabled = !!v
end

#sheet ⇒ Object

style.sheet — always non-nil for <style>. Memoized per text content (CSSOM: repeated reads return the same object), seeded with the element's CSS text so insertRule/deleteRule order against it. Rewriting the element's text discards the sheet and any rules inserted via CSSOM — browsers re-parse into a fresh sheet too.

# File 'lib/dommy/html_elements.rb', line 4571

def sheet
  text = text_content.to_s
  return @__sheet if @__sheet && @__sheet_text == text

  @__sheet_text = text
  @__sheet = CSSStyleSheet.new(
    owner_node: self,
    media: media,
    title: @__node__["title"].to_s,
    type: (type.empty? ? "text/css" : type),
    source_text: text
  )
