URLPattern: hash property
Baseline
2025
Newly available
Since September 2025, this feature works across the latest devices and browser versions. This feature might not work in older devices or browsers.
Note: This feature is available in Web Workers.
The hash read-only property of the URLPattern interface is a string containing the pattern used to match the fragment part of a URL.
This is the normalized value of the hash pattern passed to the constructor, an inherited value from a baseURL passed to the constructor, or the default value ("*"), which matches any hash.
Value
A string.
Examples
Basic usage
The below example creates a URLPattern object with books/:id for the hash part and logs the property.
This pattern matches any fragment that starts with books/ and ends with an arbitrary string identifier.
const pattern = new URLPattern("https://example.org#books/:id");
console.log(pattern.hash); // 'books/:id'
console.log(pattern.test("https://example.org#books/123")); // true
