我怎么可以张贴在MVC项目列表 [英] How can I post a list of items in MVC
问题描述
我有它的项目列表的形式简单，我想它们发布到控制器，但有趣的是，我只是不能。其他一切能够顺利进行，除了列表。我查了Ajax调用的萤火虫和后值是有这样的：
I have a simple form with a list of items in it and I'd like to post them to the controller but funny thing is I just cant. Everything else goes through properly except the list. I checked the ajax call in firebug and the post values are there like this:
Answers[0].IsMissing False
Answers[0].Text Ja
Answers[0].Value 0
Answers[1].IsMissing False
Answers[1].Text Nein
Answers[1].Value 1
Id 1cd14b08-ce3b-4671-8cf8-1bcf69f12b2d
Name Ja/Nein
我有以下属性的AnwserScheme类：
I have an AnwserScheme class with the following properties:
public string Name { get; set; }
public bool IsMissing { get; set; }
public List<AnswerDisplayItem> Answers { get; set; }
public AnswerScheme()
{
Answers = new List<AnswerDisplayItem>();
}
我有这样的看法code：
I have this view code:
@for (int i = 0; i < Model.Answers.Count; i++) {
<tr>
<td>
@Html.HiddenFor(model => Model.Answers[i].IsMissing)
@Html.TextBoxFor(model => Model.Answers[i].Value,
new { @class = "inputValue" })
</td>
<td>
@Html.TextBoxFor(model => Model.Answers[i].Text,
new { @class = "inputAnswer" })
</td>
<td>
<span class="span-delete"
data-answer-scheme-id="@Model.Id"
data-answer-id="@Model.Answers[i].Id" >x</span>
</td>
</tr>
}
我有这块阿贾克斯code，负责发布：
I have this piece of ajax code that is responsible for posting:
$.ajax({
url: "/AnswerScheme/AddAnswer",
type: "post",
data: $("#formAnswerScheme").serialize(),
success: function (data) {
console.log(data);
$("#divAnswerSchemeContainer").html(data);
}
});
我在我的控制器中添加答案行动：
I have an add answer action in my controller:
[HttpPost]
public PartialViewResult AddAnswer(AnswerScheme answerScheme)
{
...some logic comes here
}
那么，到底控制器临危模型，而只是简单的特性，不在名单。任何帮助将大大AP preciated！欢呼声。
So in the end the controller recieves the model, but only the simple properties, not the list. Any help would be greatly appreciated! cheers.
推荐答案
我希望能看到更多的类和code的，因为你没有的东西树立正确的。
I wish I could see more of your classes and code, because you don't have something set up right.
我重新从你做了什么提供，其工作的东西。我创建了一个MVC 3项目，该样本。
I recreated something from what you did provide, which works. I created an MVC 3 project for this sample.
