hash is a read/write string property of the URL object. It specifies the anchor portion of a URL, including the leading hash (#) mark. For example, the hash property of the following (fictitious) URL is "#result".
This anchor portion of a URL refers to a named position within the data referenced by the URL. In HTML files positions are named with anchors created with the <A NAME="anchor_name"> tag.
