我有json绑定到视图模型的问题.这是我的代码：
部分viewmodels(Addressviewmodel有更多的属性)：
public class Addressviewmodel { [Display(Name = "Address_Town",ResourceType = typeof(Resources.PartyDetails))] public string Town { get; set; } [Display(Name = "Address_Country",ResourceType = typeof(Resources.PartyDetails))] public Country Country { get; set; } } public class Country : EntityBase<string> { public string Name { get; set; } protected override void Validate() { if (string.IsNullOrEmpty(Name)) { base.AddBrokenRule(new BusinessRule("CountryName","required")); } } }
使用Javascript：
$(document).on("click","#addAddress",function () {
var jsonData = {
"Town": $('#txt-Town').val(),"District": $('#txt-District').val(),"Street": $('#txt-Street').val(),"PostCode": $('#txt-PostCode').val(),"FlatNumber": $('#txt-FlatNumber').val(),"PremiseName": $('#txt-PremiseName').val(),"PremiseNumber": $('#txt-Premisenumber').val(),"Country": {
"Name": $('#txt-Country').val(),}
};
var addressData = JSON.stringify(jsonData);
$.ajax({
url: '/Customer/SaveAddress',type: "POST",dataType: "json",contentType: "application/json; charset=utf-8",data: addressData,success: function (result) {
$("#addIndividualAddressDialog").data("kendoWindow").close();
},error: function (result) {
alert("Failed");
}
});
});
控制器负责人：
[HttpPost] public ActionResult SaveAddress(Addressviewmodel addressviewmodel)
这是我用firebug看到的：
这就是我在VS看到的：
正如你所看到的,普通属性被绑定正确,但我的嵌套对象(国家)是空的.我读了很多不同的文章,我仍然不知道我做错了什么.请帮帮我！
解决方法
问题来自于你的action方法参数：
[HttpPost] public ActionResult SaveAddress(Addressviewmodel addressviewmodel)
当你使用JSON.stringify(),你发送一个字符串到您的控制器,而不是一个对象！所以,你需要做一些工作来实现你的目标：
1)更改您的动作方法参数：
[HttpPost] public ActionResult SaveAddress(string addressviewmodel)
2)将该字符串反序列化为一个对象 – 即Addressviewmodel：
IList<Addressviewmodel> modelObj = new JavaScriptSerializer().Deserialize<IList<Addressviewmodel>>(addressviewmodel);
所以,你最后的行动方法应该如下：
[HttpPost] public ActionResult SaveAddress(string addressviewmodel) { IList<Addressviewmodel> modelObj = new JavaScriptSerializer().Deserialize<IList<Addressviewmodel>>(addressviewmodel); // do what you want with your model object ... }
