我正在尝试将复选框列表中的值数组绑定到具有字节属性类型的模型。所以我从复选框选择中返回 {"1", "2" , "3"} 在它到达我的模型之前我需要它以字节格式，以便它可以正确地传递给我的模型。属性字节 { 获取；放; }

我的淘汰视图模型 where self.DaysList = ko.observableArray(); 是我的复选框列表属性。

function ScheduledCommand() {
    //data
    var self = this;
    // An observable is a “JavaScript object that can notify subscribers about changes.” 
    // When the contents of an observable change, the view is automatically updated to match.
    self.ScheduledCommandId = ko.observable();
    self.NextOccurence = ko.observable();
    self.CommandType = ko.observable();
    self.CommandAssembly = ko.observable();
    self.IntervalAmount = ko.observable();
    self.IntervalType = ko.observable();
    self.Catchup = ko.observable();
    self.Retry = ko.observable();
    self.SendToQueue = ko.observable();
    self.Enabled = ko.observable();
    self.SelectedCommand = ko.observable();
    self.DaysList = ko.observableArray();

    var Command = {
        ScheduledCommandId: self.ScheduledCommandId,
        NextOccurence: self.NextOccurence,
        CommandType: self.CommandType,
        CommandAssembly: self.CommandAssembly,
        IntervalAmount: self.IntervalAmount,
        IntervalType: self.IntervalType,
        Catchup: self.Catchup,
        Retry: self.Retry,
        SendToQueue: self.SendToQueue,
        Enabled: self.Enabled,
        SelectedCommand: ko.observable(),
        DaysList: ko.observableArray(),
    };

    self.Command = ko.observable();
    self.Commands = ko.observableArray();
    self.get = function () {
        $.ajax({
            url: '/api/Values',
            cache: false,
            type: 'GET',
            contentType: 'application/json; charset=utf-8',
            data: {},
            success: function (data) {
                self.Commands(data); //Put the response in ObservableArray
                $("#btnGetCommands").hide();
                $("#commandlist").show();
                $("#btnHideCommands").show();
            }
        });
    }

    self.hidecommands = function ()
    {
        $("#btnGetCommands").show();
        $("#btnHideCommands").hide();
        $("#commandlist").hide();
    }
    //ko.bindingHandlers.bootstrapPopover = {
    //    init: function (element, valueAccessor, allBindingsAccessor, Command) {
    //        var options = valueAccessor();
    //        var defaultOptions = {};
    //        options = $.extend(true, {}, defaultOptions, options);
    //        $(element).popover(options);
    //    }
    //};

    self.create = function (formElement) {
        if (Command.NextOccurence() != "" && Command.CommandType() != "" && Command.CommandAssembly() != "") {
            $.ajax({
                url: '/api/Values',
                cache: false,
                type: 'POST',
                contentType: 'application/json; charset=utf-8',
                data: ko.toJSON(Command),
                success: function (data) {
                    // alert('added');
                    self.Commands.push(data);
                    self.DaysList("");
                    self.NextOccurence("");
                    self.CommandType("");
                    self.CommandAssembly("");
                    self.IntervalAmount("");
                    self.IntervalType("");
                    self.Catchup("");
                    self.Retry("");
                    self.SendToQueue("");
                    self.Enabled("");
                    alert("Command " + self.CommandType() + " successfully created.")
                }
            }).fail(
                     function (xhr, textStatus, err) {
                         alert(err);
                     });

        }
        else {
            alert('Please Enter All the Values !!');
        }
    },
        self.selectCommand = function (command) {
            self.SelectedCommand(command.ScheduledCommandId)
            alert(command.ScheduledCommandId);
        },
    document.getElementById("btnGetCommands").onclick
}
$(document).ready(function () {
    // When the DOM is fulled loaded, call the ko.applyBindings function and pass 
    // in a new instance of the commandViewModel:
    $("#btnHideCommands").hide();
    $("#commandlist").hide();
    ko.applyBindings(new ScheduledCommand());
    // The ko.applyBindings method activates Knockout and wires up the view-model to the view.
});

我的 API 控制器方法这对 DaysList 没有价值

    public HttpResponseMessage Post(ScheduledCommand model)
    {
        repo.Add(model);

        var response = Request.CreateResponse<ScheduledCommand>(HttpStatusCode.Created, model);

        string uri = Url.Link("DefaultApi", new { id = model.ScheduledCommandId });

        response.Headers.Location = new Uri(uri);

        return response;
    }

最后是我的复选框列表。

         @foreach (var item in ViewData["checklist"] as IEnumerable<SelectListItem>)
         { 
            <div class="checkbox">
              <label>
                <input type="checkbox" data-bind="attr: { value: @item.Value}, checked: $root.DaysOfWeek">
                @item.Text
              </label>
            </div>
         }

它的 Knockout 方面很好，它返回了我想要的内容，但我无法将其转换为字节。感谢您的时间！

我想要做的是尝试在将可淘汰的可观察数组传递给服务器之前将其转换为字节，以满足参数类型（小整数）。相反，我所做的是创建一个“占位符”（字符串数组）属性并将其转换为字节以满足我的数据属性。

我只是希望使用 javascript 删除额外的步骤。
