Question

我使用knockoutjs使用foreach循环在表格中显示多条记录，在用户点击行编辑时，在我们软件的先前版本中，它显示了tr中的输入字段，以便用户可以编辑。现在我的任务是在用户单击特定tr的用户名时在bootstrap弹出窗口中显示输入字段。问题是当我点击任何一行时，它只在模态弹出窗口中显示第一行的数据。以下是我的完整页面代码

<div class="hidden cstm-right-sc" data-bind="css: { hidden: false }" id="AdminPanel">

请帮助我，我是淘汰赛的新手。这非常重要。

Answer 1

您在myModal内多次创建ID为foreach: Users的模式，因此您有多个具有相同ID的模态。它打开了第一个使用该ID找到的模态，这是第一个记录。您需要唯一地命名模态，例如

<td>
    <span data-bind="click: $root.Edit, text: LoginName,
          css: { clickable: $root.EditId() === null },
          attr: {'data-target', '#myModal' + Id()}"
          data-toggle="modal"></span>
</td>

和

<tr class="modal fade" data-bind="attr: { id: 'myModal' + Id()}"
    role="dialog" tabindex="-1">

在弹出窗口中编辑数据时，仅显示knockoutjs中所有行的第一行数据
