[英]Posting javascript array of objects to MVC4 controller
This is my controller action: 这是我的控制器动作:
public ActionResult BrowsePartial(IList<SearchParam> searchParams = null)
{
//...
}
This is the object model: 这是对象模型:
public class SearchParam
{
public string Order { get; set; }
public string Type { get; set; }
public string Value { get; set; }
}
And here is how i send data to controller: 这是我如何将数据发送到控制器:
$.ajax(
{
type: "GET",
url: url,
data: { searchParams: [{ Order: "fghfdhgfdgfd", Type: "sasdsa", Value: "saddsadsads" }, { Order: "fghfdhgfdgfd", Type: "sasdsa", Value: "saddsadsads" }, { Order: "fghfdhgfdgfd", Type: "sasdsa", Value: "saddsadsads" }] },
mode: "replace",
cache: false,
});
Now, when i debug the action, i have an IList<SearchParam>
that is correctly initialized with 3 elements. 现在,当我调试动作时,我有一个
IList<SearchParam>
,它已正确初始化为3个元素。 However, fields of each SearchParam
object ( Order
, Type
and Value
) are initialized to null. 但是,每个
SearchParam
对象( Order
, Type
和Value
)的字段都初始化为null。 What could be the problem here? 这可能是什么问题?
I think, the only way you can send your array parameter in a single request is to stringify it, and deserialize in your controller. 我认为,在单个请求中发送数组参数的唯一方法是对其进行字符串化,并在控制器中进行反序列化。
$.ajax(
{
type: "GET",
url: url,
data: { searchParams: JSON.stringify([{ Order: "fghfdhgfdgfd", Type: "sasdsa", Value: "saddsadsads" }, { Order: "fghfdhgfdgfd", Type: "sasdsa", Value: "saddsadsads" }, { Order: "fghfdhgfdgfd", Type: "sasdsa", Value: "saddsadsads" }])},
mode: "replace",
cache: false,
});
public ActionResult BrowsePartial(string searchParams = null)
{
SearchParam params = JsonConvert.DeserializeObject<SearchParam>(searchParams);
}
But I maybe mistaken ;) 但我可能错了;)
