データ属性

次のデータ属性を要素に対して利用することで、Turbo の挙動をカスタマイズできます。

原文

The following data attributes can be applied to elements to customize Turbo’s behaviour.

data-turbo="false" disables Turbo Drive on links and forms including descendants. To reenable when an ancestor has opted out, use data-turbo="true". Be careful: when Turbo Drive is disabled, browsers treat link clicks as normal, but native adapters may exit the app. Note that if Turbo ignores a path, then setting data-turbo="true" will not force/override it to enable.

  • data-turbo-track="reload" tracks the element’s HTML and performs a full page reload when it changes. Typically used to keep script and CSS link elements up-to-date.
  • data-turbo-track="dynamic" tracks the element’s HTML and removes the element when it is absent from an HTML response. Typically used to remove style and link elements during navigation.
  • data-turbo-frame identifies the Turbo Frame to navigate. Refer to the Frames documentation for further details.
  • data-turbo-preload signals to Drive to pre-fetch the next page’s content
  • data-turbo-prefetch="false" disables prefetching links when the element is hovered.
  • data-turbo-action customizes the Visit action. Valid values are replace or advance. Can also be used with Turbo Frames to promote frame navigations to page visits.
  • data-turbo-permanent persists the element between page loads. The element must have a unique id attribute. It also serves to exclude elements from being morphed when using page refreshes with morphing
  • data-turbo-temporary removes the element before the document is cached, preventing it from reappearing when restored.
  • data-turbo-eval="false" prevents inline script elements from being re-evaluated on Visits.
  • data-turbo-method changes the link request type from the default GET. Ideally, non-GET requests should be triggered with forms, but data-turbo-method might be useful where a form is not possible.
  • data-turbo-stream specifies that a link or form can accept a Turbo Streams response. Turbo automatically requests stream responses for form submissions with non-GET methods; data-turbo-stream allows Turbo Streams to be used with GET requests as well.
  • data-turbo-confirm presents a confirm dialog with the given value. Can be used on form elements or links with data-turbo-method.
  • data-turbo-submits-with specifies text to display when submitting a form. Can be used on input or button elements. While the form is submitting the text of the element will show the value of data-turbo-submits-with. After the submission, the original text will be restored. Useful for giving user feedback by showing a message like “Saving…” while an operation is in progress.
  • download opts out of Turbo since the link is for downloading files and not navigation.
