使用复杂模型验证局部视图？
我有一个时间表应用程序，我在其中使用 jQuery 加载 PartialView。一切正常，但我不知道如何验证输入。我尝试按照以前的方式进行操作，但它不起作用：
<% for (int i = 0; i < Model.Tasks.Count; i++)
{
var task = Model.Tasks[i];
%>
<tr class="taskrow">
<td class="customer">
<%: task.Customer.CustomerName %>
</td>
<td class="task">
<%: task.TaskName %>
</td>
<% for (int j = 0; j < task.TimeSegmentList.Count; j++)
{ %>
<td>
<%: Html.TextBoxFor(model => model.Tasks[i].TimeSegmentList[j].Hours, new { @class = "hourInput" })%>
<%: Html.ValidationMessageFor(model => model.Tasks[i].TimeSegmentList[j].Hours)%>
</td>
<% } %>
</tr>
<% } %>
虽然此 PartialView 是使用 jQuery 加载的，但它还包含一个提交到操作方法的提交按钮。
因为我使用的是实体框架，所以我读到我需要使用 DataAnnotations 来装饰模型，如下所示：
[MetadataType(typeof(TimeSegmentMetaData))]
public partial class TimeSegment
{
public class TimeSegmentMetaData
{
[Range(0,24,ErrorMessage = "Must be between 0 and 24 hours")]
public object Hours { get; set; }
}
}
所以我想确保在此处输入的 Hours 是 0 到 24 之间的数字。 （我还想确保它是一个 int，但我还没有做到这一点，需要首先进行验证）
所以这不起作用，我做错了什么？是否无法执行此操作，因为我在 PartialView 中有带有 for 循环的复杂模型？
我也在考虑尝试找到某种严格的 jQuery 验证（我已经看到为此存在 jQuery 插件），但我不知道如何在 PartialView 中使用 jQuery。因为当 document.ready 函数位于主（父）视图中时，如何让 jQuery 运行？无论如何我都需要这个，因为以后我希望能够在用户选择输入字段时执行一些操作...
PS：我对 jQuery 和 MVC 仍然相当陌生，所以我真的很感激关于以下方面的明确指示：我做错了什么...谢谢！
I have a timesheet application where I load a PartialView with jQuery. Everything works fine, but I have no idea how to validate the input. I have tried to do it similarly to how I've done it before, but it doesn't work:
<% for (int i = 0; i < Model.Tasks.Count; i++)
{
var task = Model.Tasks[i];
%>
<tr class="taskrow">
<td class="customer">
<%: task.Customer.CustomerName %>
</td>
<td class="task">
<%: task.TaskName %>
</td>
<% for (int j = 0; j < task.TimeSegmentList.Count; j++)
{ %>
<td>
<%: Html.TextBoxFor(model => model.Tasks[i].TimeSegmentList[j].Hours, new { @class = "hourInput" })%>
<%: Html.ValidationMessageFor(model => model.Tasks[i].TimeSegmentList[j].Hours)%>
</td>
<% } %>
</tr>
<% } %>
Although this PartialView is loaded using jQuery, it also contains a submit button which submits to an action method.
Because I'm using the Entity Framework I have read that I need to decorate the model with DataAnnotations like this:
[MetadataType(typeof(TimeSegmentMetaData))]
public partial class TimeSegment
{
public class TimeSegmentMetaData
{
[Range(0,24,ErrorMessage = "Must be between 0 and 24 hours")]
public object Hours { get; set; }
}
}
So I want to make sure it's a number between 0 and 24 entered here for Hours. (I would also like to make sure it's an int, but I haven't gotten to that yet, need to make validation work at all first)
So this doesn't work, what am I doing wrong? Is it not possible to do this because I have the complex model with the for loop in the PartialView?
I was also thinking of trying to find some sort of strict jQuery validation (I've seen jQuery plugins exist for this), but I can't figure out how to use jQuery within the PartialView. Because how can I get jQuery to run when the document.ready function is within the main (parent) view? I would need this anyway, because later I want to be able to do things if a user selects an input field...
PS: I'm still rather new to both jQuery and MVC, so I'd really appreciate clear pointers as to what I'm doing wrong... Thanks!

我首先将类型更改为 Int。另外，您可以使用 foreach 而不是 For 循环
I would start by changing the type to an Int. Also, you can use foreach instead of the For loop
