我使用asp.net和web表单。
在我的项目中，我有asmx web服务
在我的项目中，我有asmx web服务
[WebMethod]
public string GetSomething()
{
// avoid circual reference(parent child)
List<RetUsers> res = repo.GetAllUser().Select(c => new RetUsers {User_ID = c.User_ID,User_Name = c.User_Name,Date_Expire = c.Date_Expire }).ToList();
string res1 = res.ToJson();
// extension methods
return res.ToJson();
}
结果是这种格式。
[
{"User_ID":1,"User_Name":"Test 1","Date_Expire":null},{"User_ID":2,"User_Name":"Test 2","Date_Expire":null}
]
1 – Test 1,2 – Test 2.
解决方法
返回列表，并使用[ScriptMethod(ResponseFormat = ResponseFormat.Json)]属性 – 它将创建JSON对象作为自动返回：
[WebMethod]
[ScriptMethod(ResponseFormat = ResponseFormat.Json)]
public List<RetUsers> GetSomething()
{
// avoid circual reference(parent child)
List<RetUsers> res = repo.GetAllUser().Select(c => new RetUsers {User_ID = c.User_ID,Date_Expire = c.Date_Expire }).ToList();
return res;
}
在JS方面：
$.ajax(
{
type: "POST",async: true,url: YourMethodUrl,data: {some data},contentType: "application/json; charset=utf-8",dataType: "json",success: function(msg)
{
var resultAsJson = msg.d // your return result is JS array
// Now you can loop over the array to get each object
for(var i in resultAsJson)
{
var user = resultAsJson[i]
var user_name = user.User_Name
// Here you append that value to your label
}
}
})
