Gadget-HotCat.js

Pyynnön esittäjä: --Usp 21. maaliskuuta 2008 kello 22.51 (UTC)

Suora linkki keskusteluun: Wikipedia:Kahvihuone (tekniikka)#Gadget-HotCat.js pienoisohjelmaksi

Esimerkki muualta: Commons

Apuväline nopeaan luokitteluun. .js lisättäisiin pienoisohjelmaksi kuten Commonsissa.

Ensiksi keskustelu tekniikkakahvihuoneelle (vaikka en epäile etteikö tämä laajennus olisi riittävän hyödyllinen niin tehdään nyt kaiken taiteen sääntöjen mukaan ettei kohta ole kymmenen tusinaa pienoisohjelmaa joista yhdeksän tusinaa on vain yhden käyttäjän käytössä). --Agony (403) 22. maaliskuuta 2008 kello 06.52 (UTC)

Ei näyttänyt herättävän vastustusta joten vaihe 2 olisi lokalisointi (koodi ohessa). --Agony (403) 1. huhtikuuta 2008 kello 17.28 (UTC)

AJAX-pikaesikatselu pienoisohjelmaksi

Esimerkki muualta: en:User:Alex Smotrov/qpreview.js

Olen käyttänyt jonkin aikaa AJAX-pikaesikatselua ja se toimii. Sillä voidaan esikatsella tekstiä huomattavasti nopeammin kuin jo olemassa olevalla esikatselulla. Tekijän koodi en:User:Alex Smotrov/qpreview.js

Etuja:

• Mahdollistaa nopean (lähes välittömän, jos sivu ei ole kovin pitkä) esikatselun
• Koodin muokkauksia voi kumota esim. ctrl+z -yhdistelmällä
• sivu ei siirry alkuun vaan pysyy muokkausruudun kohdalla
• muokkausruutu pysyy paikallaan, eli ei siirry aina alkuun esikatseltaessa, mikä on pitkissä sivuissa (kuten kahvihuone) todella hyvä ominaisuus
• avaa "avattava"-mallineet aina

"Huonoja" puolia:

• ei päivitä luokkia
• ei päivitä käytetyt mallineet listaa
• ei päivitä kielilinkkejä
• varsinainen esikatselu alkaa tuntumaan harmillisen hitaalta ja siirtymä alkuun sivulla ja muokkausruudussa huonolta ominaisuudelta.

Minulla esikatselu toimi suoraan lisäämällä omaan monobook.js :ään koodi:

//AJAX-pikaesikatselu
// install [[User:Alex Smotrov/qpreview.js]]
qPreviewKey = '`'; // accesskey: ~
qPreviewName = 'Pikakatselu';  
qPreviewWait = 'Odota…'
qPreviewAtBottom = true;
document.write('<script type="text/javascript" src="'
+ 'http://en.wikipedia.org/w/index.php?title=User:Alex Smotrov/qpreview.js'
+ '&action=raw&ctype=text/javascript"></' + 'script>');

Eli ei taida tarvita muuta lokalisoinita kuin painikkeiden nimien suomentaminen. --Usp 2. huhtikuuta 2008 kello 19.00 (UTC)

Muokkaa-linkki

Suora linkki keskusteluun: Wikipedia:Kahvihuone (tekniikka)#Miksi muokkaa-linkki karkailee

Esimerkki muualta: fr:Mediawiki:Common.js (Déplacement des [modifier])

Muokkaa-linkin muuttaminen siten että se sijoittuu suoraan otsikon viereen. Toteutettava myös javascript-koodi liitettäväksi omaan monobook.js-tiedostoon jolla tämä muutos voidaan kumota.
