我在選擇菜單的Html部分視圖沒有得到更新，而返回更新的部分視圖。我錯過了什麼？
@using (Html.BeginForm("userrights", "Users", FormMethod.Post, new { @class = "form-horizontal", role = "form", @id = "userrights_frm", @name = "userrights_frm" }))
{
<div class="form-group">
<div class="col-md-7" style="padding-right:10px">
@Html.TextBoxFor(m => m.firstname, new { @class = "form-control", @id = "firstname", @name = "firstname", @placeholder = "Serach By User Name" })
@Html.HiddenFor(m => m.id, new { @class = "form-control", @id = "id", @name = "id" })
</div>
<div class="col-sm-2">
<button type="submit" id="btn_search" value="Search" name="btn_search" class="btn btn-default">Search</button>
</div>
<div class="clearfix"></div>
</div>
<div class="form-group">
<div class="col-md-1" style="padding-top:7px"> Select Top Link </div>
<div class="col-sm-6">
@Html.DropDownList("selectedMenu", Model._menu.Select(menu => new SelectListItem { Text = menu.menuname, Value = menu.menuid.ToString() }), "Select Menu", new { @class = "form-control" })
</div>
<div class="clear"></div>
</div>
@Html.Partial("_userRightPartial", Model._UserRightPartialView)
<div class="clear"></div>
}
AjaxMethod改變
$("#selectedMenu").change(function() {
mnid = $(this).val();
userId = $("#userid").val();
$.ajax({
type: 'POST',
url: "/Users/getsubmenus",
data: "{userid:'" + userId + "',menuid:'" + mnid + "'}",
contentType: "application/json; charset=utf-8",
dataType: 'json',
success: function (data) {
if (data.result == "Error") {
alert(data.message);
}
}
});
});
操作結果稱爲Ajax 「的getsubmenus」
public ActionResult getsubmenus(string userid, string menuid)
{
userright _userright = new userright();
user _user = _ftwCommonMethods.GetuserDataById(Convert.ToInt32(userid));
UserRightPartialView _UserRightPartialView = new UserRightPartialView();
if (_user!=null)
{
IEnumerable<SubMenuListModel> _SubMenuListModel = _ftwCommonMethods.GetSubMenuItemsByMenu(_user.id.ToString(), menuid);
_UserRightPartialView.firstname = _user.firstname;
_UserRightPartialView.userid = _user.id;
_UserRightPartialView._SubMenuListModel = _SubMenuListModel;
}
return PartialView("_userRightPartial", _UserRightPartialView);
}
的ActionResult當我點擊搜索按鈕
[HttpPost]
[AuthorizeUser]
public ActionResult userrights(FormCollection form_collection)
{
IEnumerable<MenuListModel> _MenuListModel = _ftwCommonMethods.GetMenuItems();
int userid = 0;
if (!string.IsNullOrEmpty(form_collection["id"].ToString()) && form_collection["id"].ToString() != "0")
{
userid = Convert.ToInt32(form_collection["id"].ToString());
}
user _user = _ftwCommonMethods.GetuserDataById(userid);
UserRightViewSearch _UserRightViewSearch = new UserRightViewSearch();
_UserRightViewSearch._menu = _MenuListModel;
if (_user != null)
{
IEnumerable<SubMenuListModel> _SubMenuListModel = _ftwCommonMethods.GetSubMenuItems(_user.id.ToString());
UserRightPartialView _UserRightPartialView = new UserRightPartialView();
_UserRightPartialView.firstname = _user.firstname;
_UserRightPartialView.userid = _user.id;
_UserRightViewSearch.id = _user.id;
_UserRightPartialView._SubMenuListModel = _SubMenuListModel;
_UserRightViewSearch._UserRightPartialView = _UserRightPartialView;
}
else
{
ViewData["message"] = "User Not Found.";
}
return View(_UserRightViewSearch);
}

的事情是，當我搜索記錄我得到了局部視圖的所有子菜單項開始。然後我想要做的是當我選擇特定的菜單鏈接下拉部分視圖應該只更新所選菜單的子菜單
你需要停止可怕的使用嘗試覆蓋'id'和'name'屬性具有完全相同的值，他們已經是我在上一個問題中提到的（'new + @ name =「 ..「'甚至不起作用）。你可以在ajax選項中指定'dataType：'json'，但你實際返回的html（'PartialView'），所以它會失敗。將其更改爲'數據類型：「HTML」，'並以'URL：「@ Url.Action（‘getsubmenus’，‘用戶’）」，'以確保您的網址是正確生成 –
您也有其他問題的局部視圖因爲您的'foreach'循環中的控件正在生成重複的'name'屬性而沒有索引器，所以不會綁定到模型及其由於重複的'id'屬性而生成無效的html。您需要使用'for'循環或自定義'EditorTemplate' –
刪除重複的ID和名稱，但沒有用..不工作 – Atul
