Document: fragmentDirective property

Baseline 2025

Newly available

Since March 2025, this feature works across the latest devices and browser versions. This feature might not work in older devices or browsers.

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

The code below logs whether or not text fragments are supported in your browser by checking for existence of the object. Note that the object is empty, and at present it is mainly intended for feature detection. In the future, it might include other information.

<pre id="log"></pre>

const logElement = document.querySelector("#log");
function log(text) {
  logElement.innerText = text;
}

#log {
  height: 20px;
}

if (document.fragmentDirective) {
  log("Your browser supports text fragments.");
} else {
  log("Text fragments are not supported in your browser.");
}
