javascript - Offline App with depended ajax dropdowns - using local sqlitedb -


i have offline "app" (web page) using combination of html/css/js/sqlite/json working -- leveraging google chrome. able store submitted data local form local sqlite db - via js. have button click function feed submitted local data cloud - remote internet mysql database. along -- have simple html button when clicked - can refresh remote data cloud (mysql database) local pc (sqlite) - refreshing local users sqlite source data - using json/php apis (pushing , pulling data)

the 1 thing struggling with, how overcome (w/o creating full blow app or installing wamp/xampp) development of these local web pages use ajax drive dependent drop-down menu selections - on local form (for example: selecting state drive menu city names) - within console error log see "cross origin requests supported protocol schemes: http, data, chrome, chrome-extension, https" messages.

is possible this? - ....where of code on local device? (without php , web server) - if so, recommendations? can of if on our public web server - effort, need of locally.

here tables: create table customer ( cid int primary key, name varchar(32) ) create table ord ( oid int primary key, cid int foreign key references customer, address varchar(20) ) here's linq-to-sql statement: var aaa = c in db.customer select new { c, o = c.ord.tolist() }; and here's inexplicable query generated linq-to-sql: select [t0].[cid] [cid], [t0].[name] [name], [t1].[oid] [oid], [t1].[cid] [cid2], [t1].[address] [address], (select count(*) [dbo].[ord] [t2] [t2].[cid] = [t0].[cid]) [value] [dbo].[customer] [t0] left outer join [dbo].[ord] [t1] on [t1].[cid] = [t0].[cid] order [t0].[cid], [t1].[oid] i want understand how rid of count(*) part. it's entirely uncalled for! linq needs count(*) in order determine number of entries returned o = c.ord.tolist() .
