【问题描述】：
我需要从动作方法运行部分视图作为子动作方法，但它会将我重定向到另一个视图。
1- 我尝试使用Html.Action("myAction","myController") 和[ChildActionOnly] 数据注释，但没有任何好处
2- 我尝试使用Html.RenderAction("myAction", "My Controller")，并将操作方法更改为PartialViewResult 和return PartialView("View", myData)，但没有任何好处。
3- 我尝试使用 JQuery AJAX，但也没有任何好处。
** 这是控制器
[Authorize(Roles = "Admin")]
[HttpPost]
[ChildActionOnly]
public ActionResult _GetUserRoles(string UserName)
{
SqlParameter param1 = new SqlParameter("@UserName", UserName);
try
{
IList<GetUserRolesViewModel> roles = Identitydb.Database.SqlQuery<GetUserRolesViewModel>("admin.sp_GetUserRoles @UserName",
((ICloneable)param1).Clone()).ToArray().ToList();
return View(roles);
}
catch (Exception ex)
{
ViewBag.Error = ex.ToString();
return RedirectToAction("ErrorSaveData");
}
}
** 这是部分查看代码
@model IEnumerable<AMSIdentity.Controllers.GetUserRolesViewModel>
@if (Model == null)
{
<table></table>
}
else
{
<table class="table table-responsive table-striped table-hover table-bordered table-condensed container" style="margin-top: 5%;">
<thead>
<tr>
<th>
@Html.DisplayNameFor(model => model.Name)
</th>
<th>
@Html.DisplayNameFor(model => model.Id)
</th>
</tr>
</thead>
<tbody>
@foreach (var item in Model)
{
<tr>
<td>
@Html.DisplayFor(modelItem => item.Name)
</td>
<td>
@Html.DisplayFor(modelItem => item.Id)
</td>
</tr>
}
</tbody>
</table>
<br />
@Html.ActionLink("Return Back", "RemoveRoleFromUser", "Manage")
}
** 这是父页面代码
ViewBag.Title = "RemoveRoleFromUser";
var error = ViewBag.Error as IEnumerable<String>;
}
<h2> Remove role from user </h2>
<ul></ul>
<div class="row container">
<div class="col-md-6">
@using (Html.BeginForm())
{
@Html.AntiForgeryToken()
<div class="form-horizontal">
<hr />
@Html.ValidationSummary(true, "", new { @class = "text-danger" })
<div class="form-group">
@Html.Label("Username", htmlAttributes: new { @class = "control-label col-md-2" })
<div class="col-md-10">
@Html.Editor("UserName", new { htmlAttributes = new { @class = "form-control" } })
</div>
<hr />
@Html.Label("Role Id", htmlAttributes: new { @class = "control-label col-md-2" })
<div class="col-md-10">
@Html.Editor("RoleId", new { htmlAttributes = new { @class = "form-control" } })
</div>
</div>
<div class="form-group">
<div class="col-md-offset-2 col-md-10">
<input type="submit" value="Remove" class="btn btn-default btn-danger" />
</div>
</div>
</div>
}
</div>
<div class="col-md-6">
<div class="row container">
<div class="col-md-12">
<h3> Get user roles </h3>
@using (Html.BeginForm("_GetUserRoles", "Manage", FormMethod.Post))
{
@Html.AntiForgeryToken()
<div class="form-horizontal">
<hr />
@Html.ValidationSummary(true, "", new { @class = "text-danger" })
<div class="form-group">
@Html.Label("Username", htmlAttributes: new { @class = "control-label col-md-2" })
<div class="col-md-10">
@Html.Editor("UserName", new { htmlAttributes = new { @class = "form-control" } })
</div>
</div>
<div class="form-group">
<div class="col-md-offset-2 col-md-10">
<input type="submit" value="Get rules" class="btn btn-default btn-success" id="btnRules"/>
</div>
</div>
</div>
}
</div>
</div>
<div class="row container">
<div class="col-md-12">
@Html.Partial("_GetUserRoles")
</div>
</div>
</div><!--Second Column-->
</div> <!--End of row-->
@section Scripts {
@Scripts.Render("~/bundles/jqueryval")
}
** 这是视图模型
public class GetUserRolesViewModel
{
[DisplayName("Username")]
public string Name { get; set; }
[Key]
[DisplayName("Role Id")]
public string Id { get; set; }
}
** 这是我用来运行局部视图的 AJAX 代码
<script type="text/javascript">
//$(document).ready(function ()
//{
$("#btnRules").click(function (e)
{
var UserName = $("#UserName").val();
$.ajax({
url: '/Manage/_GetUserRoles',
dataType: 'html',
data:{"UserName": UserName},
success: function (data)
{
$('#listRules').html(data);
},
error: function (xhr, ajaxOptions, thrownError)
{
alert('Failed to retrieve rules.');
}
});
});
//});
</script>
** 路线图片
Route Config Picture
我希望在 RemoveRoleFromUser 的同一视图中部分运行 Action Method (_GetUserRoles)。
【问题讨论】：
-
请分享jQuery ajax 代码。使用 jQuery ajax 应该可以工作。
-
@akg179 我在上面添加了 JQuery AJAX 代码。
