我正在尝试遍历数据库并为每条记录创建一个文本框。在我尝试使用控制器中的信息之前,一切正常。如何将此信息传递回控制器?
<% Using (Html.BeginForm("NewEnvCd", "Config", Nothing, FormMethod.Post))%>
<%: Html.Hidden("Environment", Model.NewEnvironment)%>
<div class="box" style="margin-top:30px;width:800px;">
<h4 >Add New Environment Code</h4>
<div>
<div>
<div style="float:left; text-decoration:underline;">Environment Code</div><div style="float:right;width:400px;text-decoration:underline;">Parameter Values</div>
</div>
<br /><br />
<% Dim i As Int32 = 0 %>
<% For Each cfg In Model.ParameterValues%>
<div style="margin-bottom:5px;">
<div style="float:left;">
<%: Html.Hidden("newEnvironment", Model.NewEnvironment)%>
<%: Html.Hidden("cfg[" & i & "].Name", cfg.Name) %>
<%: Html.Hidden("cfg[" & i & "].EnvCd", cfg.EnvCd) %>
<%: cfg.Name%>
</div>
<div style="float:right;">
<%: Html.TextBox("cfg[" & i & "]value", If(Not cfg.Value Is Nothing, cfg.Value, ""), New With {.style = "width:400px;"})%>
</div>
<div class="clear"></div>
</div>
<% i += 1 %>
<% Next %>
<input type="submit" value="Save" />
<%: Html.ActionLink("Return to List", "Index", "Config") %>
</div>
</div>
<% End Using %>
控制器如下所示:
Function NewEnvCd(ByVal newEnvironment As String, Optional ByVal copyEnvironment As String = "") As ActionResult
Dim model As NewEnvCdModel
model = New NewEnvCdModel(newEnvironment, copyEnvironment)
Return View(model)
End Function
<HttpPost()>
Function NewEnvCd(ByVal newEnvironment As String, ByVal name As String, ByVal value As String, ByVal cfg As IList(Of ConfigData.tblTT_Configuration))
If (cfg.Count() = 0 OrElse String.IsNullOrWhiteSpace(name)) Then
Return RedirectToAction("Index")
End If
For Each c In cfg
Repository.CreateEnvironment(If(c.EnvCd, newEnvironment), c.Name, c.Value)
Next
Return RedirectToAction("index")
End Function
我可能不清楚我的问题,但我正在寻找的答案与使用每个 cfg 记录的名称有关(即 cfg.Name、cfg.Value、cfg.EnvCd)。我试图单独传递 cfg 的参数(ByVal 名称作为字符串,ByVal 值作为字符串),当我应该将 cfg 作为列表或可查询(ByVal cfg As IList(Of ConfigData.tblTT_Configuration))传递时,然后从控制器中提取值。谢谢你们的帮助。
