Dgrid +选择问题

Question

仍然在尝试使用Dgrid (0.4)和dojo (1.10)，我现在有了另一个选择问题。

我的网页包含一个当你点击一个按钮时打开的对话框。在此对话框中，我们有以下代码，这些代码通过Json HTTP页面显示包含来自数据库的数据的网格。这可以很好地工作，甚至排序和查询过滤。

我想要做的是允许用户双击一行，获得第一列中包含的选定行Id，以更新主页中的表单。为此，我使用了dgrid/selection。但是，它总是返回网格的最后一行，而不是用户选择的那一行。

选择代码基于此：http://dgrid.io/tutorials/0.4/hello_dgrid/

有什么想法吗？

谢谢

Answer 1

只是找到了原因。这些列需要有一个名为ID的'id‘列，我只需将'contact_id’列改为'id‘，它就能正常工作。

谢谢
