我在使用Formvalidator.io时遇到了一些问题，我的猜测是它与我的代码嵌套有关...
我在下面的代码示例中的第972行收到错误。错误如下：
Uncaught TypeError: Cannot read property 'id' of null
代码中的第972行是：
var selected_department_id = $('#departmentName').select2('data').id;
当我尝试验证表单时会触发错误。
在console.log(selected_department_id)上我得到了预期的结果，所以我知道该函数已声明并按预期工作。
有人对可能导致此错误的内容有任何建议吗？

return obj;
