Question

我想创建一种我已列出

的表格

我将以某种模式将一些MVC模型映射到Ko ViewModel：

function User(data) {
    this.userAlias = ko.observable(data.UserAlias);
    this.userFirstName = ko.observable(data.UserFirstName);
    this.userLastName = ko.observable(data.UserLastName);
};

function Day(data) {
    var self = this;

    self.date = ko.observable(data.Date);
    self.dateStr = ko.observable(data.dateStr);
    self.dtDay = ko.observable(data.dtDay);
    self.value = ko.observable(data.Value);

    self.users = ko.observableArray([]);
};

users的{{1}}值是Day()的数组如何构建有效的数组以将其用作参数？

Answer 1

如果您正在进行ajax调用，Day view model看起来会像这样......

function Day(data) {
    var self = this;

    self.date = ko.observable(data.Date);
    self.dateStr = ko.observable(data.dateStr);
    self.dtDay = ko.observable(data.dtDay);
    self.value = ko.observable(data.Value);

    self.users = ko.observableArray([]);

    var users = this.users;

    //get users and push into observable array
    $.getJSON('url', function (json) {
            var mappedData = ko.utils.arrayMap(json, function (u) {
                return new User(u.UserAlias, u.UserFirstName, u.UserLastName);
           });
         users(mappedData);
      });
};

你的标记看起来像这样......

data-bind="foreach: users"

Answer 2

您可以使用ko.toJSON，如下所示：

var raw = ko.toJSON(self.users());

Knockoutjs - 我可以使用View Model参数创建foreach绑定吗？
