Instance Method Details

#embed_code(options = {}) ⇒ Object

Generates some HTML code that allows embedding of the resource of the current request. Creates an iframe element with the embed link as src attribute. HTML options can be customized. Returns a string.

Examples

Assuming the current request is ‘/’ (root):

embed_code()
# => "<iframe width="560" height="315" src="http://localhost:3000/embed" frameborder="0"
    sandbox="">Your Browser does not support HTML iFrame Element.</iframe>"

embed_code(fallback: "")
# => "<iframe width="560" height="315" src="http://localhost:3000/embed" frameborder="0"
    sandbox=""></iframe>"

embed_code(width: 760, height: 500)
# => "<iframe width="760" height="500" src="http://localhost:3000/embed" frameborder="0"
    sandbox="">Your Browser does not support HTML iFrame Element.</iframe>"

embed_code(width: nil, height: nil)
# => "<iframe src="http://localhost:3000/embed" frameborder="0" sandbox="">Your Browser
    does not support HTML iFrame Element.</iframe>"

  embed_url = current_page_embed_url
  return nil unless embed_url.present?

  # set values
  fallback = options.delete(:fallback) || "Your Browser does not support HTML iFrame Element."
  default_html = {width: 560, height: 315, src: embed_url, frameborder: 0, sandbox: ''}
  default_html.merge!(options)

  # create element
  element = content_tag(:iframe, fallback, default_html)
  "#{element}"
end
