Localization in a web app using JavaScript and JSON -

-

i'm trying set script automatically localize web application. web application intended use html5's offline caching ability, needs able work offline. such, javascript seems me best option.

i'd prefer put strings localizations in single json file so:

{     "en": {         "application_description": "this application's description in english.",         "application_name": "this application's name in english."     },     "ja": {         "application_description": "this application's description in japanese.",         "application_name": "this application's name in japanese."     } }

i thinking maybe of giving elements localized custom attribute linking intended message (eg: i18n="application_name").

i can retrieve browser's language using navigator.language, though think results have split first section (eg: "en-us" "en-gb" , "en-au" should refer "en").

however, javascript knowledge basic, , while i've thought it, cannot determine how implement this.

many can offer tips or examples!

you can use wikimedia's jquery.i18n.

c# - Is it possible to remove an existing registration from Autofac container builder? -

something along lines: builder.registertype<mytype>().as<itype>(); builder.registertype<mytype2>().as<itype>(); builder.deregistertype<mytype>().as<itype>() var container = builder.build(); var types = container.resolve<ienumerable<itype>>(); assert.istrue(types.count == 1); assert.istrue(types[0].gettype == typeof(mytype2)); scenario: go through bunch of assemblies , go register types want make sure have 1 implementation of given type. need before create container. track on own nice if autofac me bit. this cannot done directly using containerbuilder , unless start on new one. mind you, having first built container should able construct new container filtering away unwanted types , reusing registrations first container. this: ... var container = builder.build(); builder = new containerbuilder(); var components = container.componentregistry.registrations .where(cr => cr.activator.limittype != typ...

php - Mysql PK and FK char(36) vs int(10) -

-
i have read mysql can handle indexes , searches better if tables keys integers rather char(36) uuid's. is worth converting int(10)? note: use 1 server , have have plans use multiple databases concurrently therefore removing 1 of big reasons using uuid. our tables innodb if makes difference. thanks in advance. usually rdbms can handle integer keys pk more efficient, other datatypes. reason how build index column, yes: long dont require string (or other typed) keys, should use integers. however: char(36) , int(10) far away being equal, because int(10) much smaller, char(36). dont know, if require many different keys, should keep in mind. update, complete last paragraph: int(10) 32-bit, char(36) 36 - ^byte^ (= 288-bit). not mean, int consumes less space, means, char(36) has 4 times more different keys.
