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); }
