我尝试了淘汰赛映射样本,并认为我几乎没有。 我似乎没有能够在新富加入到viewModel.foos - 任何人都可以看到我在这里错过了吗?
var Foo = function (data) {
var self = this;
self.id = data.id;
self.Name = ko.observable(data.Name);
}
var dataMappingOptions = {
key: function(data) {
return data.id;
},
create: function (options) {
return new Foo(options.data);
}
};
var viewModel = {
foos: ko.mapping.fromJS([]),
loadInitialData: function () {
ko.mapping.fromJS(serverData, dataMappingOptions, viewModel.foos);
},
loadUpdatedData: function () {
ko.mapping.fromJS(serverData, dataMappingOptions, viewModel.foos);
}
};
viewModel.addFoo = function () {
viewModel.foos.push(ko.mapping.fromJS(new Foo()));
viewModel.loadUpdatedData();
}
