I'm getting data from a WCF service,and i map, and bind the data with my DOM object :
var PayinyVM = {};
$.getJSON('/service/PaidService.svc/PaidList', function (data) {
var tmp = JSON.stringify(data.d);
PayinyVM.model = ko.mapping.fromJSON(tmp);
ko.applyBindings(PayinyVM);
});
the result is shown as excepted on my DOM bind it to model. What I couldn't find out is how to add some computed observable let's say my data is returning people with FirstName and LastName, how can I make a computed observable FullName with FN + ' ' + LN.
Here's a working copy of your fiddle, I had to make a lot of assumptions as your fiddle wasn't even correct javascript and seemed quite confused and didn't even reference knockout
var PaidPeople = function(data) {
var self = this;
ko.mapping.fromJS(data, {}, this);
this.fullName = ko.computed(function () {
return self.Name() + " : just ";
});
}
var PayinyVM = function (data) {
var self = this;
ko.mapping.fromJS(data, {
'model' : {
create: function(options) {
return new PaidPeople(options.data);
}
}
}, self);
};
var data = {model:[{__type: "PaidPeople:#model", Amount:110, Attendee:1, Name:'John'}]};
ko.applyBindings(new PayinyVM(data));
and a fiddle that works : http://jsfiddle.net/qeUHd/
