How to remove Empty Properties from a multi depth JavaScript Object? -

-

i've got js object: 

var test = {"code_operateur":[""],"cp_cult":["",""],"annee":["2011"],"ca_cult":[""]}

when use function: 

for (i in test) {      if ( test[i] == "" || test[i] === null ) {          delete test[i];       }   }

i get: 

{"cp_cult":["",""],"annee":["2011"]}

okay not bad, i'd remove empty "cp_cult" property (which array , not string other).

note: don't want manually delete key!

try:

function isempty(thingy) {  for(var k in thingy){   if(thingy[k]) {    return false;   }  }  return true; }  for(i in test) {  if ( test[i] == "" || test[i] === null || (typeof test[i] == "object" && isempty(test[i])) ) {   delete test[i];  } }

however, depending on complexity of object, you'd need more advanced algorithms. example, if array can contain array of empty strings (or more levels) , should deleted, you'd need check well.

edit: trying make fit needs, please have at: http://jsfiddle.net/jvhne/

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.
