Just dipping my toes into the world of knockoutjs, I've got this viewmodel set up:
var Testing = function(){
this.Username = ko.observable("");
this.Password = ko.observable("");
this.email = ko.observable("");
}
I'm tasked with converting only specific data bind values (Username and Password) into JSON. Currently, all values are being converted when I use data = ko.toJSON(this);
Any ideas on how to filter certain data bind values and convert them into JSON?
If you prefer, you can choose to only serialize specific data or follow Ryan Neidermeyer's method of eliminating undesirable properties -
var elements = ko.toJS(this);
var updatedElements = ko.utils.arrayMap(elements, function(element) {
delete element.email;
return element;
});
If you want to customize how your ViewModel is serialized to JSON, simply create a toJSON method in your ViewModel and apply any necessary filtering:
ViewModel.prototype.toJSON = function() {
var copy = ko.toJS(this);
// Remove unnecessary properties before returning the copy
delete copy.unneededProperty;
return copy;
}
For more details on serializing data to JSON with Knockout.js, refer to the official documentation.
