我在客户端使用ASP.NET和jQuery。
我使用Json.NET在服务器端序列化DB中的数据,并在Ajax请求到达时将其发送到客户端。
当我打开FireBug时,我看到以下json:
{"d":"[rn {rn "CategoryID": 1,rn "CategoryName": "a",rn "Description": "123",rn "CategoryType": "Personal",rn "Traits": [rn {rn "TraitID": 1,rn "TraitName": "a",rn "Description": "aaa"rn },rn {rn "TraitID": 1,rn "TraitName": "a",rn "Description": "aaa"rn }rn ]rn },rn {rn "CategoryID": 1,rn "CategoryName": "b",rn "Description": "bla bla",rn "CategoryType": "Professional",rn "Traits": [rn {rn "TraitID": 1,rn "TraitName": "a",rn "Description": "aaa"rn },rn {rn "TraitID": 1,rn "TraitName": "a",rn "Description": "aaa"rn }rn ]rn },rn {rn "CategoryID": 1,rn "CategoryName": "c",rn "Description": "123",rn "CategoryType": "Personal",rn "Traits": [rn {rn "TraitID": 1,rn "TraitName": "a",rn "Description": "aaa"rn },rn {rn "TraitID": 1,rn "TraitName": "a",rn "Description": "aaa"rn }rn ]rn },rn {rn "CategoryID": 1,rn "CategoryName": "d",rn "Description": "bla bla",rn "CategoryType": "Professional",rn "Traits": [rn {rn "TraitID": 1,rn "TraitName": "a",rn "Description": "aaa"rn },rn {rn "TraitID": 1,rn "TraitName": "a",rn "Description": "aaa"rn }rn ]rn }rn]"}
我的服务器端代码:
[WebMethod]
public static string LoadRatingForm()
{
bll_Trait t1 = new bll_Trait();
t1.TraitID = 1;
t1.TraitName = "a";
t1.Description = "aaa";
bll_Trait t2 = new bll_Trait();
t2.TraitID = 1;
t2.TraitName = "a";
t2.Description = "aaa";
bll_Trait t3 = new bll_Trait();
t3.TraitID = 1;
t3.TraitName = "a";
t3.Description = "aaa";
bll_Trait t4 = new bll_Trait();
t4.TraitID = 1;
t4.TraitName = "a";
t4.Description = "aaa";
bll_Category c1 = new bll_Category();
c1.CategoryID = 1;
c1.CategoryName = "a";
c1.CategoryType = "Personal";
c1.Description = "123";
c1.Traits.Add(t1);
c1.Traits.Add(t2);
bll_Category c2 = new bll_Category();
c2.CategoryID = 1;
c2.CategoryName = "b";
c2.CategoryType = "Professional";
c2.Description = "bla bla";
c2.Traits.Add(t3);
c2.Traits.Add(t4);
bll_Category c3 = new bll_Category();
c3.CategoryID = 1;
c3.CategoryName = "c";
c3.CategoryType = "Personal";
c3.Description = "123";
c3.Traits.Add(t1);
c3.Traits.Add(t2);
bll_Category c4 = new bll_Category();
c4.CategoryID = 1;
c4.CategoryName = "d";
c4.CategoryType = "Professional";
c4.Description = "bla bla";
c4.Traits.Add(t3);
c4.Traits.Add(t4);
List<bll_Category> list = new List<bll_Category>();
list.Add(c1);
list.Add(c2);
list.Add(c3);
list.Add(c4);
return JsonConvert.SerializeObject(list, Formatting.Indented);
}
我的jQuery代码:
$.ajax({
type: "POST",
url: "MyProfile.aspx/LoadRatingForm",
data: "{}",
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function (response) {
var html;
var categories = response.d;
$.each(categories, function (i, category) {
// create
//while (category.CategoryType == "Professional") {
//
//}
html += category.CategoryName + " ";
});
dialog.append(html);
},
error: function () {
alert("ERROR");
}
});
"dialog"变量是jQuery UI模式对话框,$.ajax代码位于对话框的"open"事件处理程序中。。。
我应该怎么做才能使序列化结果为"正确"的json格式,而不包含任何'\n'、'\r'和'\'?
提前感谢!
您不应该手动对该List进行JSON序列化。
当您通过POST调用ASP.NET并使用内容类型application/json
时,ASP.NET已经在自动为您执行此操作。因此,您最终会得到一个双重序列化的响应,这就是为什么您发现在jQuery已经解析了一次之后,您需要再次解析它。
如果您使用List的返回类型并直接返回列表,那么您的状态应该很好。

您可以尝试return JsonConvert.SerializeObject(list, Formatting.None);
你看过这个相关的问题ASP.NET+jQuery,如何去序列化JSON?。可能与Content-Type标头有关。
编辑:见注释,并没有解析JSON。
根据JSON规范:"空白可以插入任何一对令牌之间。"
http://www.json.org/
所以不用担心。
