view向controller提交列表

第一次将view中列表提交到controller,尝试了下,还是可以的

要传输的实体类

    /// <summary>
    /// 用于展示的角色类
    /// </summary>
    public class Action4Role
    {
        /// <summary>
        /// 行为Id
        /// </summary>
        public string ActionId { get; set; }
        /// <summary>
        /// 角色Id
        /// </summary>
        public string RoleId { get; set; }
        /// <summary>
        /// 角色名字
        /// </summary>
        public string ActionName { get; set; }
        /// <summary>
        /// 所属项目名称
        /// </summary>
        public string ApplicationName { get; set; }
        /// <summary>
        /// 是否授权
        /// </summary>
        public bool IsAuthorize { get; set; }
    }

get请求

        public ActionResult ActionRole(string RoleId)
        {
            var allActions = PowerService.GetActions().ToList();
            var role = new Role4Select() { Id = RoleId };
            var roles = PowerService.GetRoles(role).ToList();
            ViewData["RoleName"] = PowerService.GetRoleById(RoleId).Name;
            return View(roles);
        }

@model List<DTOs.Role.Action4Role>

@{
    ViewBag.Title = "ActionRole";
    Layout = "~/Views/Shared/_Layout.cshtml";

        @for (int i = 0; i < Model.Count() ; i++)

<script>
    $(function () {
        $('#checkAll').change(function () {
            var isAll = document.getElementById('checkAll').checked;
            $checkBoxs = $('input[type="checkbox"]').each(function () {
                $(this).prop("checked", isAll);
            })
        })
    })
</script>

post请求

        [AcceptVerbs(HttpVerbs.Post)]
        public ActionResult SaveActionRoleList([Form]IEnumerable<Action4Role> actionList)
        {
            var roleId = actionList.First().RoleId;
            var IsAuthRoleIds = actionList.Where(a => a.IsAuthorize).Select(a => a.ActionId);
            var NoAuthRoleIds = actionList.Where(a => !a.IsAuthorize).Select(a => a.ActionId);
            PowerService.RoleAddAction(roleId, IsAuthRoleIds.ToArray());
            PowerService.RoleDeleteAction(roleId, NoAuthRoleIds.ToArray());
            return RedirectToAction("RoleList");
        }

以前总以为Model和字典在view和controller之间的通讯没有太多区别,也通过这个需求加深了对Model的理解.

加油,相信自己,明天可以的!
