在部分视图中基于viewdata更改BeginForm操作？

Question

我有一个在同一页面上多次存在的部分视图。这将添加到视图中：

@Html.Partial("PersonalTagPartial", Model.PT, new ViewDataDictionary{{"TagTypeControl", 1}} )

@Html.Partial("PersonalTagPartial", Model.PT, new ViewDataDictionary{{"TagTypeControl", 0}} )

然后在部分视图中，我得到了一个这样的提交表单：

@using (Html.BeginForm("AddPersonalTag", "Post", FormMethod.Post, new { id = "frmAddPersonalTags" })){

当TagTypeControl设置为0时，如何将AddPersonalTag更改为RemovePersonalTag？

Answer 1

试试这样：

@using (Html.BeginForm((ViewBag.TagTypeControl == "1" ? "AddPersonalTag" : "RemovePersonalTag"), "Post", FormMethod.Post, new { id = "frmAddPersonalTags" }))
{
    ...
}

但你也可以直接将动作名称传递给partial：

@Html.Partial("PersonalTagPartial", Model.PT, new ViewDataDictionary { { "SubmitTo", "AddPersonalTag" } })
@Html.Partial("PersonalTagPartial", Model.PT, new ViewDataDictionary { { "SubmitTo", "RemovePersonalTag" } })

然后在部分内部：

@using (Html.BeginForm(ViewBag.SubmitTo, "Post", FormMethod.Post, new { id = "frmAddPersonalTags" }))
{
    ...
}
