eh-fixed-tagfield - adds a tag field fixed to the browser window
The script (eh-fixed-tagfield.user.js) adds an extra semi-transparent tag field at the top left corner of the browser window. The new field will work in the same way as the tag field at the top of the gallery page but will not change into buttons to withdraw or downvote. For downvoting you still need to go to the main tag field.
Two major design decisions can be seen in the script:
-
There is an event listener bound to the entire window, which may be annoying and even conflicting with other scripts. Yet the code for the handler is in one place and can be safely commented out, the script works without that event. The event exists only for the convenience of using the TAB button to gain focus to the new tag field.
-
The autocomplete function uses .indexOf() because it is an incredibly fast method (no regex matching over a long list) yet it has the bad side that it does not carry over the case. This should not be visible since EH tags are all lowercase and most people would never input upper case letters, yet it may prove to be a strange behaviour to some.
The fetish tag autocomplete needs to understand separation of tags with commas. The commas work for voting but do not work for the completion. In other words, the completion only works when a single tag is in the field.
The code is dependent on the reverse engineering of the exiting Javascript on the page of an EH gallery. Changes to the JavaScript present on the page may break this script. Best efforts were made to not interfere with the main tag field, and after testing I could not find any interference. Yet my reverse engineering of the code on the page may be slightly off so bug may appear.
