JavaScript: The Definitive Guide, 6th Edition

Name

URL — Blob URL methods

Synopsis

The URL property of the Window object refers to this URL object. In the future, this object may become a constructor for a URL parsing and manipulation utility class. At the time of this writing, however, it simply serves as a namespace for the two Blob URL functions described below. See Blobs and Blob URLs for more on Blobs and Blob URLs.

The URL object is new at the time of this writing and the API is not yet stable. You may need to use it with a vendor-specific prefix: webkitURL, for example.

Functions

string createObjectURL(Blob blob)

Return a Blob URL for the specified blob. HTTP GET requests for that URL will return the contents of blob.

void revokeObjectURL(string url)

Revoke the specified Blob url, so that it is no longer associated with any Blob and can no longer be loaded.
