是否建议在原型对象上创建计算属性?
这是我在下面尝试过的,但是firstName
绑定将函数作为字符串返回,而不是执行它(http://jsfiddle.net/W37Yh)。
var HomeViewModel = function(config, $, undefined) {
if (!this instanceof HomeViewModel) {
return new HomeViewModel(config, $, undefined);
}
this.firstName = ko.observable(config.firstName);
this.lastName = ko.observable(config.lastName);
};
HomeViewModel.prototype.fullName = function() {
return ko.computed(function() {
return this.firstName() + " " + this.lastName();
}, this);
};
var model = new HomeViewModel({
firstName: "John",
lastName: "Smith"
}, jQuery);
ko.applyBindings(model);
