创建了一个数据库，保存了一个文档。检索的文档，已编辑的文档，试图用新值将文档放回原位。

我正在取回NaN

var TotalDrills;
TotalDrills = new PouchDB(currentDB);

var doc = {
"_id": "DrillCount","TotalDrillCount": 0.0,"_rev": success._rev,};
TotalDrills.put(doc);



TotalDrills.get("DrillCount",function (failure,success) {
if (failure) {
console.log("Error getting Drill: " + failure); }  
else {
console.log("TotalDrills database TotalDrillsQuantity id 
Successfully got Drill: " + success);
TotalDrillsCount = success.TotalDrillCount;
TotalDrillsCount = parseInt(TotalDrillsCount);
console.log(TotalDrillsCount);
console.log("just .val: " + TotalDrillsCount);
}
});
console.log("TotalDrillsCount: " + TotalDrillsCount);
