Question

If i define object like

var Person = function(id, name, country) {
    var self = this;
    self.id = ko.observable(id);
    self.name = ko.observable(name);
    self.country = ko.observable(country); 

    return self;
};

How can i remove property “country” from this object on click event of button. Thing is that when i send data to webservice i dont want to send this property to it.

Please see fiddle here where i am trying to remove property “country” on click event of save button.

You have to delete this property from all objects:

this.SaveDetail = function() {
    ko.utils.arrayForEach(people(), function(item){
        delete item["country"];                 
    });
};

Here is working fiddle: http://jsfiddle.net/nZDrk/8/
