javascript - Convert certain data bind values into Json using Knockoutjs -

i new knockoutjs, have next viewmodel:

var testing = function(){ this.username = ko.observable(""); this.password = ko.observable(""); this.email = ko.observable(""); }

i need convert info bind values(username , password) json. values getting converted json when utilize data = ko.tojson(this);

so how can filter info bind values , convert json ?

you either serialize want or take ryan neidermeyer's approach , remove unwanted properties -

var items = ko.tojs(this); var mappeditems = ko.utils.arraymap(items, function(item) { delete item.email; homecoming item; });
