The
DOM location interface exposes the HTML document's URI parsed into its properties. However, it is
ancient and has problems that bug me but otherwise rarely show up in the real world. Complaining about mostly theoretical issues is why blogging exists, so here goes:
- The location object's search, hash, and protocol properties are all misnomers that lead to confusion about the correct terms:
- The 'search' property returns the URI's query property. The query property isn't limited to containing search terms.
- The 'hash' property returns the URI's fragment property. This one is just named after its delimiter. It should be called the fragment.
- The 'protocol' property returns the URI's scheme property. A URI's scheme isn't necessarily a protocol. The http URI scheme of course uses the HTTP protocol, but the https URI scheme is
the HTTP protocol over SSL/TLS - there is no HTTPS protocol. Similarly for something like mailto - there is no mailto wire protocol.
- The 'hash' and 'search' location properties both return null in the case that their corresponding URI property doesn't exist or if its the
empty string. A URI with no query property and a URI with an empty string query property that are otherwise the same, are not equal URIs and are allowed by HTTP to return different content.
Similarly for the fragment. Unless the specific URI scheme defines otherwise, an empty query or hash isn't the same as no query or
hash.
But like complaining about
the number of minutes in an hour none of this can ever change without huge compat issues on the web.
Accordingly I can only give my thanks to Anne van Kesteren and the awesome work on the
URL standard moving towards a more sane (but still working
practically within the constraints of compat) location object and URI parsing in the browser.

can be revoked and replaced. How do you revoke a finger?"

Sarah and I got an exercise bike on sale and when attempting to put it together found that it was missing a bag of about ten different screws. The manufacturer website said we could order
a replacement bag for thirty dollars (!!) but since the instructions listed the various kinds of screws we needed I figured we could just go to a hardware store and buy them.
We started at Home Depot because I didn't know better. The screws are all listed in metric sizes which is apparently uncommon and a helpful senior worker forwarded us to McLendons whose stock was better but we were again redirected this time to Tacoma Screw Products.
Tacoma Screw Products is great! See them for your hardware needs first! The store has a back area with every kind of screw ever. I felt a little out of place as as all the customers looked like
contractors. The employee who helped me explained the various options I had in screws as the bike instructions weren't as explicit as they could have been. In the end I bought all my screws for
only one dollar (much better than $30!) and they all fit correctly.
