i have jquery validator plugin , need have ajax validation method. first of all, tried use remote , understand sends element's value , uses element's name. if need other parameter name instead of element's name? method can applied different form elements class , need sure send same parameter element's value. so, if have this: <input name="zip1" class="zip" /> <input name="zip2" class="zip" /> and rule config this: remote: 'http://example.com' then ajax calls 'example.com/?zip1=value' , 'example.com/?zip2=value' , while need have specific parameter name. another thing need process response , i'm not sure how remote . so i'm thinking creating custom method instead of using remote , ajax call parameter name want, process response , set validation status. is there better solution?

in entity framework 6 there multiple way of adding / removing entities, example adding entities, can use:- b.students.add(student); db.savechanges(); or db.entry(student).state = entitystate.added; db.savechanges(); and when deleting object:- db.entry(studenttodelete).state = entitystate.deleted; db.savechanges(); or db.remove(studenttodelete) db.savechanges(); i did not find resources talks differences , , of online tutorials mention both approaches if same. have read reply on article link using dbset.add set status entity , related entities/collections added, while using entitystate.added adds related entities/collections context leaves them unmodified, , same thing applies dbset.remove & entitystate.deleted so these differences correct ? edit as understand graph operation means both parent , child got deleted/added , if parent marked deletion or addition. did these 2 tests :- using (var db = new testcontext()) { var = new department { departmen...

i have trouble understanding how worst case time complexity of constructing suffix tree linear - particularly when need build suffix tree string may composed of repeating single character such "aaaaa". even if construct compressed suffix tree "aaaaa", won't able compress nodes since no 2 edges starting out of node can have string-labels beginning same character. this result in suffix tree of height 5, , @ each insertion of suffix, need keep traversing root leaf. here how approached: suffixes: a, aa, aaa, aaaa, aaaaa create root node, create edge bearing 'a' , connect new node, left bears "$", , repeat process until can aaaaa. this result in o(n^2) instead of o(n). missing here? i agree comments, here more details: the procedure describe forming aaaaa tree o(n), not o(n^2). node , leaf creation constant-time operations, , perform them n==5 times. assumption of o(n^2) seems based on idea you'd traverse root leaf in ...

currently, using standard setup node.js + passport + ajax webserver, backbone on client, , app server exposing apis back-end. client makes ajax request node, housecleaning such checking session authentication, passes request along app server. we experimenting replacing ajax portion between client , node websockets. part have working fine. using passport check if request authenticated. standard node route, request , response included trivial task, i'm not sure how socket. var server = http.createserver(app).listen(port); var io = socketio.listen(server); var namespaced = io.of('/socket/test'); namespaced.on('connection', function (socket) { console.log('a user connected /socket/test'); socket.on('fetch', function (args) { // client has sent socket message functionally replace ajax request // authenticate session here - how request?? }); });
