我有一个 PartialView 在这样调用时可以正常工作:
<div id="EmailAddresses">
@foreach (FormEmailMessageEmailAddress toRecipient in Model.ToRecipients)
{
@Html.Partial("~/Views/FormEmailMessageEmailAddresses/_Edit.cshtml", toRecipient)
}
</div>
下一部分代码,我有一个 Ajax 调用,它返回模型并添加到 DOM:
<div class="form-group">
<div class="col-md-10" style="float: right;">
@Ajax.ActionLink(
"Add",
"AddNewEmailAddress",
null,
new { id = Model.Oid },
new AjaxOptions
{
HttpMethod = "GET",
InsertionMode = InsertionMode.InsertAfter,
UpdateTargetId = "EmailAddresses",
},
new { style = "btn btn-info" }
)
</div>
</div>
“~/Views/FormEmailMessageEmailAddresses/_Edit.cshtml”看起来基本上是这样的:
@model x.Models.Forms.Actions.FormEmailMessageEmailAddress
@using (Html.BeginCollectionItem(ViewData.TemplateInfo.HtmlFieldPrefix + ".ToRecipients"))
{
@* Bunch of omitted code *@
}
从数据库条目填充 PartialView 时,Html.BeginCollectionItem 字符串看起来类似于EmailMessages[997a1db6-6205-4118-90e4-11013d8d33db].ToRecipients[780bd8fa-4121-4d45-8fbc-35f4b8fd3086]
,但是,当从 Ajax 函数调用时,它看起来像.ToRecipients[222a5fa2-70d6-4cac-afbc-e865b0a753be]
。
因为缺少前缀,控制器看不到新的集合。
使用HtmlFieldPrefix
Ajax 调用或其他我不正确的东西时没有信息,请让我知道您的想法,以便为我提供解决方案。
