I am using the Google maps API along with the HTML 5 geolocation API to display my position as a marker on a map. Once this marker is displayed I have a simple on marker double-click function that saves a new marker to my current position using indexedDB. Everything goes well until the Object is about to be stored, then I received the message "Uncaught DataCloneError: Failed to execute 'put' on 'IDBObjectStore': An object could not be cloned." in the console. my code is as follows:
function initialize() {
var mapProperties = { // Set the maps properties
center: new google.maps.LatLng(55.8580, -4.2590),
zoom: 8,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(document.getElementById("map-overview"), mapProperties); //Display the map in the map-overview div
function NogeoLocation(e) { //A function to handle users that do not have Geolocation
if (e) {
var content = 'Error: Unfortunately the Geolocation service failed.';
} else {
var content = 'Error: Sorry, Your web browser doesn\'t support geolocation.';
}
var options = { //Error options
map: map,
position: new google.maps.LatLng(60, 105), //Set new position on Error
content: content //Display error message
};
var infowindow = new google.maps.InfoWindow(options);
map.setCenter(options.position);
}
//Using HTML5 Geolocation
if (navigator.geolocation) {
navigator.geolocation.getCurrentPosition(function (position) {
var position = new google.maps.LatLng(position.coords.latitude,
position.coords.longitude);
var contentString = "Here is your current location!" + "<button onclick='myBtn()'>Save</button>"
var infowindow = new google.maps.InfoWindow({
content: contentString
});
var marker = new google.maps.Marker({
position: position,
map: map,
title: 'My House'
});
google.maps.event.addListener(marker, 'click', function () {
infowindow.open(map, marker);
});
var db;
function indexedDBOk() {
return "indexedDB" in window;
}
google.maps.event.addListener(marker, 'dblclick', function () {
alert("dbl Click");
console.log(position);

var openRequest = indexedDB.open("idarticle_people", 1);

Reset to default 11marker can't be cloned because the object stored in the map-property contains a reference to a DOMNode(#map-overview), which can't be cloned (see:Things that don't work with structured clones).
Remove the map-property, it will not be re-usable at all because the google.maps.Map-instance will not exist when you retrieve the marker later.
I discovered that the reason for the error was to try to add an object that was not recognized to a cache.
this.storage.set ("page", HomePage);
I switched to a string and it worked
this.storage.set ("page", "HomePage");
