和我喜欢的按钮clik代码

 var viewModel = {
            messages: ko.observableArray()
        };
        ko.options.useOnlyNativeEvents = true;
        ko.applyBindings(viewModel);
        $.getJSON('@Url.Action("statusMessages", "Home")', function (data) {
            viewModel.messages(data);
        });

和我的按钮html代码

var LikeButtonClick = function (id) {

            $.getJSON('@Url.Action("Like", "Home")/' + id).done(function (d) {
                if (d.State) 
                    toastr.info("Beğendiniz.");
                else
                    toastr.error("Beğenmekten Vazgeçtiniz");

                var message = ko.utils.arrayFirst(viewModel.messages(), function (currentMessage) {
                    return currentMessage.MessageId == d.Id; 
                });
                if (message) {
                    console.log(message.MessageId)
                    // refresh
                }

            })
        };

Answer 1

您似乎在某个地方有一个名为LikeCount的可观察属性，但您没有将其包含在问题中。

你需要做的地方：

var viewModel = {
        messages: ko.observableArray(),
LikeCount: ko.observable();
    };

并且在你的json中你需要更新那个observable：

viewModel.LikeCount(data.LikeCount); //or similar

Knockoutjs observablearray刷新值
