javascript - Knockout view model serialize to db and retrieve -

i have web form use knockout , have implement new feature save form draft db , later load again modify or submit.

is there feature on knockout framework serialize viewmodel other form(like json) save db. later load , populate view easily.

i know can save viewmodel json db , later can load , fill each property on view model below. im looking feature serialize , later populate whole viewmodel @ once using it.i have lot of properties , don't want fill each property writing code line below.

var somejson = /* fetched saved viewmodel json */; var parsed = json.parse(somejson);  // update view model properties viewmodel.firstname(parsed.firstname); viewmodel.pets(parsed.pets); 

use mapping plugin , replace code one:

var somejson = /* fetched saved viewmodel json */; var parsed = json.parse(somejson);  // update view model properties viewmodel = ko.mapping.fromjs(data);
