jquery – 将json提交给MVC3动作

ko.utils.postJson(LOCATIOn.href,ko.toJSON(viewmodel));

$.ajax({
    url: LOCATIOn.href,type: "POST",data: ko.toJSON(viewmodel),datatype: "json",contentType: "application/json charset=utf-8",success: function (data) { alert("success"); },error: function (data) { alert("error"); }
});

Steve Sanderson有一个较旧的示例,它演示了如何在控制器操作中正确绑定提交的JSON数据： http://blog.stevensanderson.com/2010/07/12/editing-a-variable-length-list-knockout-style/

它的要点是他创建了一个名为“FromJson”的属性,如下所示：

public class FromJsonAttribute : CustomModelBinderAttribute
{
    private readonly static JavaScriptserializer serializer = new JavaScriptserializer();

    public override IModelBinder GetBinder()
    {
        return new JsonModelBinder();
    }

    private class JsonModelBinder : IModelBinder
    {
        public object BindModel(ControllerContext controllerContext,ModelBindingContext bindingContext)
        {
            var Stringified = controllerContext.httpContext.request[bindingContext.ModelName];
            if (String.IsNullOrEmpty(Stringified))
                return null;
            return serializer.Deserialize(Stringified,bindingContext.ModelTypE);
        }
    }
}

然后,动作看起来像：

[httpPost]
    public ActionResult Index([FromJson] IEnumerable<GiftModel> gifts)

现在,您可以使用ko.utils.postJson提交数据并使用适当的视图进行响应.
