这个问题以前曾被问过,但我审查过的没有一个给出明确或完整的解决方案。我希望你能在这里帮助我。
我想使用 AjaxHelper 将从客户端输入的数据(输入文本字段)传递到服务器。如果有更优雅的解决方案,请回复与我的示例相关的代码。
我也尝试过使用 Ajax.BeginForm() 但没有成功。请记住,这里有两个按钮。一种动态附加用户在输入字段下方输入的内容。第二个按钮只是一个简单的非 ajax 发布到控制器。
使用 Ajax.ActionLink() 和局部视图“_NewRow.cshtml”动态附加项目以定义标记。
这是我的 Index.cshtml:
@model MyAccount
@using (Html.BeginForm())
{
@Html.ValidationSummary(excludePropertyErrors: true)
<fieldset>
<div class="form-element cf">
<div class="form-label">
<span>Approvers:</span>
</div>
<div class="form-input cf">
@Html.TextBox("accountName", string.Empty, new { @class = "input-search-person" })
@Ajax.ActionLink("Add", "AddRecipient", "Test",
new
{
accountName = "Value from Input here."
},
new AjaxOptions
{
UpdateTargetId = "recipientList",
HttpMethod = "POST",
InsertionMode = InsertionMode.InsertAfter
})
<div style="display: block; margin-top: 5px">
<div id="recipientList">
</div>
</div>
</div>
</div>
</fieldset>
<input type="submit" class="btn green rounded" id="Submit" name="Submit" value="Submit" />
}
这是我的 TestController.cs:
public class TestController : Controller
{
public PartialViewResult AddRecipient(string accountName)
{
MyAccount acct = new MyAccount();
acct.LastName = accountName;
acct.Email = "some email";
return PartialView("_NewRow", acct);
}
[HttpGet]
public ActionResult Index()
{
return View();
}
[HttpPost]
public ActionResult Index(IEnumerable<string> accountList, string accountName)
{
if (Request.IsAjaxRequest())
{
MyAccount acct = new MyAccount();
acct.LastName = accountName;
acct.Email = "some email";
return PartialView("_NewRow", accountName);
}
if (ModelState.IsValid)
{
RedirectToAction("AnotherAction", "AnotherController");
}
return View();
}
}
这是我的部分视图“_NewRow.cshtml”:
@model MyAccount
@using (Html.BeginCollectionItem("recipients"))
{
@Html.HiddenFor(model => model.LastName)
@Html.HiddenFor(model => model.Email)
<span>@Model.LastName<span>(@Model.Email)</span></span>
}
这是我的简单模型 MyAccount.cs:
[Serializable]
[DataContract]
public class MyAccount
{
[DataMember]
public virtual string LastName { get; set; }
[DataMember]
public virtual string Email { get; set; }
}
您的帮助将不胜感激。谢谢!
