layui页面
因为页面中的数据使用layui的form模块获取值，formData对象无法直接将多选框的值加入请求头，所以先将获取的多选按钮的值转为数组，然后使用
formData.classId=arr_box;方法，将数组追加到formData中，后台获取值。

//取消
function cancelExam() {
var index = parent.layer.getFrameIndex(window.name);

}
</script>
</body>
</html>后台获取值：
代码语言：javascript复制 @RequestMapping("updateNotice")
public boolean updateNotice(NoticeInfo noticeInfo,Integer[] classId){
return false;
}NoticeInfo为对象，因为表单中的其他值为对象中的属性，顾框架会将其他属性封装成对象接受，classId数组将接受前台的数组。
