我希望spring控制器中的多个标记复选框值在spring中执行多个删除任务，如何获取标记复选框的这些值，如图所示

这里是显示部门详细信息列表的jsp页面，我已经给出了删除多个部门的复选框选项这是我的jsp页面

并且这是我的控制器删除功能，现在它正在执行单个删除任务

Answer 1

您可以在jquery循环中构建部门ID列表：

    for ( var i = 0; i < chks.length; i++) {
        if (chks[i].checked) {
            list.add(getDepartmentId());
        }

然后通过ajax调用将其传递给您的控制器方法：

$.ajax({
  url: deleteDepartment,
  type: 'POST',
  data: list
  })
  .done(function() {
    console.log("success");
  });

在您的控制器方法中，将ID列表包含为requestParam：

deleteDepartment(@RequestParam List<String> list, @ModelAttribute("departmentForm") DepartmentForm departmentForm)

并在您的控制器方法内部执行查询以删除部门ID在您传入的列表中的所有记录。
