FragmentDirective

Baseline 2024

Newly available

Since October 2024, this feature works across the latest devices and browser versions. This feature might not work in older devices or browsers.

The FragmentDirective interface is an object exposed to allow code to check whether or not a browser supports text fragments.

It is accessed via the Document.fragmentDirective property.

The code below logs whether or not text fragments are supported in your browser by checking that Document.fragmentDirective is defined. Note that the object is empty, and at present 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.");
}
