There's nothing wrong with your IDB code. Look for your answer in the code you haven't presented, particularily the AJAX response (is your JSON parsed the way you think it is?)
Be sure to attach event listeners for the error
event. I'm positive that if your IDB "inserts nothing" then in fact it's not true that "no error is showed" and rather no error is seen due to callback mismanagement.
Here's a working implementation, modified from a previous answer I've given on this tag. This implementation doesn't have the uniqueness constraints you've put on your schema on purpose: it shows that your looping is fine. The entries below all look good.
var db_name = 'SO_22977915',
store_name = 'people';
$.ajax({
url: '/echo/json/',
type: 'post',
dataType: 'json',
data: {
json: JSON.stringify({
case1: [{
"name": "nick",
"age": 28
}, {
"name": "katie",
"age": 32
}],
case2: [{
"husband": {
"name": "Jhon",
"age": 23
},
"wife": {
"name": "Marie",
"age": 24
}
}]
})
},
success: function (data) {
var request,
upgrade = false,
doTx = function (db, entry) {
addData(db, entry, function () {
getData(db);
});
},
getData = function (db) {
db.transaction([store_name], "readonly").objectStore(store_name).openCursor(IDBKeyRange.lowerBound(0)).onsuccess = function (event) {
var cursor = event.target.result;
if (null !== cursor) {
console.log("entry", cursor.value);
cursor.continue();
}
};
},
addData = function (db, entry, finished) {
console.log('adding', entry);
var tx = db.transaction([store_name], "readwrite"),
people = [];
tx.addEventListener('complete', function (e) {
finished();
});
$.each(entry.case1, function (key, value) {
tx.objectStore(store_name).add(value);
});
$(entry.case2).each(function (key, value){
people.push(value.husband);
people.push(value.wife);
});
$.each(people, function (key, value) {
tx.objectStore(store_name).add(value);
});
};
request = window.indexedDB.open(db_name);
request.oncomplete = function (event) {
if (upgrade) {
doTx(request.result, data);
}
};
request.onsuccess = function (event) {
if (!upgrade) {
doTx(request.result, data);
}
};
request.onupgradeneeded = function (event) {
var db = event.target.result;
db.createObjectStore(store_name, {
keyPath: null,
autoIncrement: true
});
}
}
});
A cursor and console.log
shows all entries as being added:
