Question

我目前正在为我的学校进行在线网络编程的最终项目，但是我很难将特定的id从sql分配给按钮id，然后只用一个模式打开它们......这里＆＃39我的编码：

final Map<String, Object> jsonAsObj = (Map<String, Object>) JsonParser.fromJson(JsonJavaFactory.instance, body);

有两种方法可以解决您的问题：

1）你需要将你的模态代码放入while循环中。

2）如果你想拥有单一模态，那么你需要在模态打开时动态地将校园数据绑定到模态中。所以下面我更新了你的代码，以便在用户点击时使隐藏字段“校园ID”动态化从校园列表中编辑按钮：[code]通过这种方式你还需要绑定模态的其他表格数据。

通过这种方式，您还需要绑定模态的其他表单数据。添加评论
