procedure TForm1.btn1Click(Sender: TObject);
var
jo:ISuperObject;
Temp:string;
temp1:Boolean;
begin
  jo:=SO(mmo1.Text);
  ShowMessage(jo.AsJSon(False,True));
  temp:=jo['name'].AsString;
  ShowMessage(temp);
  temp:= jo['sex'].AsString; //jo[]中额的字符串大小写要一致不一致会报错比如Sex就会报错
  ShowMessage(temp);

temp:=jo['weight'].AsString;
  ShowMessage(temp);
  temp:=jo['addresses'].Asstring;
  ShowMessage(temp);
  ShowMessage(jo['tel'].AsString);
  showmessage(jo['children'].AsString);
end;
