Q976 How can I extract the directory path from the documents location?

Say you have a location of:

http://www.irt.org:8080/some/where/deep/inside/filename.htm?name=martin#anchorname

This corresponds to:

protocol://hostname:port/pathname?search#hash

Then:

alert(location.href); // displays 'http://www.irt.org:8080/some/where/deep/inside/filename.htm?name=martin#anchorname'

alert(location.protocol); // displays 'http:'
alert(location.hostname); // displays 'www.irt.org'
alert(location.host); // displays 'www.irt.org:8080'
alert(location.port); // displays '8080'
alert(location.pathname); // displays '/some/where/deep/inside/filename.htm'
alert(location.search); // displays '?name=martin'
alert(location.hash); // displays 'anchorname'

To get just the directory path, use:

alert(location.pathname.substring(0,location.pathname.lastIndexOf('/'))); // displays '/some/where/deep/inside'
