javascript - 单选按钮仅在 DataTable 的第一个表中附加一个事件

我几天来一直在寻找这个问题的解决方案，但到目前为止还没有成功。

我使用java servlet动态填充了三个表，其中DataTables包含在两个Bootstrap Modal中，其中我有单选按钮来启用或禁用使用Jquery和javascript编辑/删除的行，但由于某种原因只有第一页中的单选按钮发生该事件，而不同页面中的其他人则不执行任何操作。

这是我的jsp代码:

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>

<jsp:include page="/RetreiveAlumno" />

编辑:似乎每个页面都有另一组独立于其他页面但没有事件的单选按钮

最佳答案

从表面上看，发生的情况是您的事件并未绑定(bind)到动态元素。您需要将 yoru 事件绑定(bind)到始终存在的元素。尝试像这样绑定(bind)您的事件:

$(document).on('event','.radiobuttonclass', function(e){
   //code for event here.
});

关于javascript - 单选按钮仅在 DataTable 的第一个表中附加一个事件，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/45595307/
