$.parseJSON(data)只支持标准的JSON

$.parseJSON()只支持标准的JSON,不标准的还是用eval("("+data+")")吧

什么 是标准的呢?

key和value都带引号的就是标准的;   而且必须是双引号,单引号也不行

string msg = "";
Model.Users currentUser;
string jsonStr = "";
//JavaScriptSerializer js = new JavaScriptSerializer();
bool result = bll.UserLogin(loginID, loginPwd, out msg, out currentUser);
if (!result) {
 jsonStr = "{\"result\":\"false\",\"msg\":\"" + msg + "\"}";
 context.Response.Write(jsonStr);
} else {
 //记录登陆成功的用户到Session中
 context.Session.Add("currUser", currentUser);

 if (string.IsNullOrEmpty(redirectUrl)) {
  jsonStr = "{\"result\":\"true\",\"msg\":\"OK\",\"redirect\":\"\"}";
  context.Response.Write(jsonStr);
 } else {
  jsonStr = "{\"result\":\"true\",\"msg\":\"OK\",\"redirect':\"" + context.Server.UrlDecode(redirectUrl) + "\"}";
  context.Response.Write(jsonStr);
 }
}
