jquery ajax/post/get 传参数给 mvc的action 1.ActionResult Test1 2.View Test1.aspx 3.ajax page 4.MetaObjectMigration.cs string json convert to class 5.相关的代码下载（包含用的相关类， jquery.json.js等）

ActionResult Test1

public ActionResult Test1(string nameJS, UserInfoInputData model, string js)
{
UserInfoInputData userinfo = new UserInfoInputData();
if (!string.IsNullOrEmpty(js))
{
userinfo = (UserInfoInputData)js.ToInputDataObject(typeof(UserInfoInputData));
}

ViewData["Time"] = model.Name + "  :" + userinfo.Name;
ViewData["Time2"] = model.age;
ViewData["Message"] = "Test1  :" + nameJS + "  :" + typeof(UserInfoInputData).ToString();

ViewData["js"] = userinfo.ToJSON();

return View();
}

Test1.aspx

ajax page 四种写法

function test(parameters) {
var sjson = '{ "name~!@#$%^&*(){}|:\"<>?/.,\';\\[]v-name": "nvar", "desc": "des" } ';
var sjs = '{"Name":"jsname", "age":3}';
//get post 都可以
$.post("Test1", "nameJS=" + encodeURIComponent(sjson) + "&model.name=modelName&model.age=3" + "&js=" + encodeURIComponent(sjs));

//model.name model.Name 都可以
var json = { "nameJS": "~!@#$%^&*(){}|:\"<>?/.,';\\[]v-name",
"model.name": "modelname", "model.age": 1,
"js":'{"Name":"jsname", "age":3}'
};
$.post("Test1", json);

var param = {};
param["nameJS"] = "paramjs";
param["model.Name"] = "someone";
param["model.age"] = 2;
param["js"] = '{"Name":"jsname", "age":3, "Tags":"tag1"}';
//或者param["js"] = JSON.stringify({"Name":"jsname", "age":3, "Tags":"tag1"});
$.post("Test1", param);

var metaformJsonItem = new Object();
metaformJsonItem.nameJS = "~!@#$%^&*(){}|:\"<>?/.,';\\[]v-name";
metaformJsonItem.js = JSON.stringify({
//key:value  key注意大小写
"Name": "~!@#$%^&*(){}|:\"<>?/.,';\\[]v-jsname",
"Tags": JSON.stringify(["tag1", "tag2"]),
"age": 3,
"Ids": JSON.stringify([1, 2, 3]), //或者'[1, 2, 3]'
"Country": 0,
"Countries": JSON.stringify([1, 2])
});
metaformJsonItem["model.Name"] = "modelname";
metaformJsonItem["model.age"] = "11";

$.post("Test1", metaformJsonItem);
}
