Document: fragmentDirective property

Experimental: This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

The fragmentDirective read-only property of the Document interface returns the FragmentDirective for the current document.

Value

A FragmentDirective object.

Examples

Try running the following in a supporting browser's devtools, in a tab with one or more matched text fragments:

document.fragmentDirective;

You should get a FragmentDirective object instance returned with a structure similar to the following:

items: [
  {
    prefix: "",
    textStart: "Module Workers",
    textEnd: "",
    suffix: "support",
    type: "text",
  },
  {
    prefix: "feedback on",
    textStart: "usability",
    textEnd: "",
    suffix: "",
    type: "text",
  },
];

This functionality is mainly intended for feature detection at present, but in future, it could be expanded to include other information such as translation hints.
