我正在使用Knockout来允许在页面的网格中输入数据。在ajax调用返回后，我很难更新特定的行。
这是jsFiddle
我从小提琴中取出了ajax调用，但问题是一样的。我正在努力从ajax调用传回的数据更新特定的行observable数组。我知道你可以从服务器返回的数据绑定数组，但是由于这个项目的复杂性 - 这很难做到。
我希望能够在数据恢复时将状态更新为已保存/错误。
感谢任何帮助。
感谢。

答案 0 :(得分：1)
您似乎错过了已保存/未保存状态标签上的data-bind。它应该是：
<td>
<span class="label" data-bind="text: Status">Unsaved</span>
</td>
