Transaction undefined error when creating object store in indexedDB -



Transaction undefined error when creating object store in indexedDB -

i have problem code hope can help me with. i've set .open , it's next code (unupgradeneede, onsuccess, onerror aso.) in js file , phone call js file. seems code openingen indexeddb , creating object stores never executes. code

window.indexeddb = window.indexeddb || window.mozindexeddb || window.webkitindexeddb || window.msindexeddb; contosodata = { db: null, usedb: function (successcallback) { var request = window.indexeddb.open("contosodata", 2); request.onsuccess = function (e) { contosodata.db = request.result; console.log('indexeddb.success'); successcallback(); }; request.onupgradeneeded = function (e) { console.log('indexeddb.upgradeneeded'); contosodata.db = e.target.result; if (contosodata.db.objectstorenames.contains("bookingstore")) { contosodata.db.deleteobjectstore("bookingstore"); var bookingstore = contosodata.db.createobjectstore("bookingsstore", { keypath: "id", autoincrement: true }); bookingstore.createindex = ('title', 'title', { unique: false }); bookingstore.createindex = ('id', 'id', { unique: true }); } else if (contosodata.db.objectstorenames.contains("workerstore")) { contosodata.db.deleteobjectstore("workerstore"); var workerstore = contosodata.db.createobjectstore("workerstore", { keypath: "employeenr" }); } else if (contosodata.db.objectstorenames.contains("customerstore")) { contosodata.db.deleteobjectstore("customerstore"); var customerstore = contosodata.db.createobjectstore("customerstore", { keypath: "orgnr" }); } var machinestore = contosodata.db.objectstorenames.contains("machinestore", { keypath: "machinenr" }); contosodata.db.deleteobjectstore("machinestore"); var machinestore = contosodata.db.createobjectstore("machinestore"); }; request.onerror = function (e) { console.log('indexeddb.onerror: ' + e); }; request.onblocked = function (e) { console.log('indexeddb.locked'); }; } }; contosodata.usedb(function (db) { var transaction = contosodata.db.transaction(['bookingsstore'], 'readwrite'); var objectstore = transaction.objectstore('bookingsstore'); console.log(objectstore.name); });

and then, when seek run it, transaction undefined when seek create transaction in other js-file... i've checked js-file function open indexeddb linked in right way , order html-file. i've set breake points , looks usedb code never execute. code

function init() { contosodata.usedb(); calendar.createcalendar(); } calendar.createcalendar = function () { var transaction = contosodata.db.transaction(["bookingstore"], "readwrite"); var bookingstore = transaction.objectstore("bookingstore"); }

is there i'm missing? searched , tried find solution without success far...

will this

function init() { calendar.createcalendar(); } calendar.createcalendar = function () { var transaction = contosodata.db.transaction(["bookingstore"], "readwrite"); var bookingstore = transaction.objectstore("bookingstore"); } contosodata.usedb(init);

indexeddb

Accessing MATLAB's unicode strings from C -

Accessing MATLAB's unicode strings from C - how can access underlying unicode info of matlab strings through matlab engine or mex c interfaces? here's example. let's set unicode characters in utf-8 encoded file test.txt, read as fid=fopen('test.txt','r','l','utf-8'); s=fscanf(fid, '%s') in matlab. now if first feature('defaultcharacterset', 'utf-8') , c engevalstring(ep, "s") , output text file utf-8. proves matlab stores unicode internally. if mxarraytostring(enggetvariable(ep, "s")) , unicode2native(s, 'latin-1') give me in matlab: non-latin-1 characters replaced character code 26. need getting access underlying unicode info c string in unicode format (utf-8, utf-16, etc.), , preserving non-latin-1 characters. is possible? my platform os x, matlab r2012b. addendum: documentation explicitly states "[mxarraytostring()] supports multibyte encoded characters...
