ajax不跨域：此demo是注册页面的一部分

$.ajax({
                    url:'http://gameapi.xiaoyou-game.com/user/register',
                    type:'post',
                    dataType:'json',
                    data:{'username':username,'phone_text':phone_text},
                    success:function(data,status){
                        if(data.key == -1){
                            $('#msg').html('用户名已存在！');
                        }else if(data.key == -2){
                            $('#msg').html('手机短信验证码输入错误！');
                        }else if(data.key == 1){
                            $('#register_form').submit();
                        }
                    },
                　　error:function(){
