Javascript 无法在HTML中自动刷新两个表

我想问，为什么我不能刷新两个html表？只有一个？Javascript代码是否有问题？我已经尝试声明2个变量，并尝试为每个变量创建脚本，但仍然没有成功，我尝试将变量名称更改为唯一的变量，但仍然没有成功。我的完整代码如下：

    <!-- SALES.HTML -->

               <div id="transactions_left">

            </p>

        <div class="row">
                  <div class="col-sm-12"><b>

                            <script>
                                var table = $("#salestableid");
                                    var refresh = function() {
                                      table.load("salestable.php", function() {
                                        setTimeout(refresh, 1); 
                                      });
                                    };
                                refresh();

                                var table1 = $("#sales_countid");
                                    var refresh1 = function() {
                                      table.load("sales_count.php", function() {
                                        setTimeout(refresh1, 1); 
                                      });
                                    };
                                refresh1();
                            </script>

在

表1的刷新代码中，您可以改为刷新
表

table1.load（…）
而不是下面代码中的
table.load（…）

var table1 = $("#sales_countid");
var refresh1 = function() {
    table.load("sales_count.php", function() {
    setTimeout(refresh1, 1); 
    });
};
