-this问题已被固定的目的是通过myself-序列化包含数组
SO我试图使用knockoutJS并测试映射插件和我在与序列化,其包含一个对象的一些问题和array
下面是控制器我和下面的JavaScript,我遇到的问题是无论我尝试(你可以看到注释掉的尝试修复)我不能让儿童数组传递给JavaScript来显示孩子 - {"id":5,"name":"Testing this works","children":"[{},{}]"}
是所有通过。
有人能指出我朝着正确的方向请
namespace TestingKnockout.Controllers
{
public class child
{
int id;
String name;
public child(int id, string name)
{
this.id = id;
this.name = name;
}
}
public class HomeController : Controller
{
public ActionResult Index()
{
return View();
}
public virtual string GetData()
{
List<child> childrenList = new List<child>(){
new child(2, "bob"),
new child(4, "dave")
};
var result = new
{
id=5,
name="Testing this works",
children = childrenList
//children = Newtonsoft.Json.JsonConvert.SerializeObject(childrenList)
//children = new{ id = 2, name = "bob" }
};
//String resultsToHighlightJSON = Newtonsoft.Json.JsonConvert.SerializeObject(childrenList);
//return resultsToHighlightJSON;
return new JavaScriptSerializer().Serialize(result);// +resultsToHighlightJSON;
}
}
}
这是我的javascript:
<script language="javascript" type="text/javascript">
var originalData = {
id: 1,
name: "Main",
children: []
};
var updatedData = {
id: 1,
name: "Main",
children: [{ id: 2, name: "bob" }, { id: 3, name: "ted"}]
};
function Child(id, name) {
this.id = ko.observable(id);
this.name = ko.observable(name);
}
var options = {
children: {
key: function (data) {
return ko.utils.unwrapObservable(data.id);
}
}
}
var viewModel = ko.mapping.fromJS(originalData, options);
viewModel.counter = 1;
viewModel.addChild = function() {
viewModel.children.push(new Child(++viewModel.counter, "new"));
};
viewModel.applyUpdate = function() {
var basePath="<%: Url.Content("~/") %>";
var url = basePath + 'Home/GetData/';
$.get(url, function (response) {
var Employee = $.parseJSON(response);
$("#EditLink").html("testing this out : " + Employee.children[1].name);
//ko.mapping.fromJS(updatedData,viewModel);
ko.mapping.fromJS(Employee,viewModel);
});
}
$(document).ready(function() {
ko.applyBindings(viewModel);
});
您是否已经使用小提琴手来看看什么是真正被返回给客户端JSON? – 2013-02-18 16:00:23

啊,所有正在传递的是{“id”:5,“name”:“Testing this works”,“children”:“[{},{}]”}不是因为你不能像这样在C#中序列化一个泛型列表?尝试将其更改为数组,然后查看是否有效。 – 2013-02-18 18:45:00
