无法获取Struts2-jquery-grid行Id以进行删除
无法获取Struts2-jquery-grid行Id以进行删除
提问于 2012-10-09 12:47:10
我正在用Struts2和Jquery Grid开发一个小应用程序，用于显示数据结果。
当我点击编辑按钮时，特定的行id就会出现。但是当我单击delete按钮删除该行时，它的id就不会出现了。当对选中的行执行删除操作时，如何获取行的id (Struts2 Jquery Grid)？
请帮帮我。

我也有同样的问题。log4j调试帮助我解决了这个问题。即使您在.jsp的subjectId字段中使用了‘key="true“’，id仍然被简单地作为'id‘传递。
所以，在你的行动中，而不是：
int SubjectId;尝试：
private int id;并定义它的getter和setter。
