Question

显示注释代替脚本通常输出的最简单方法是什么？

我目前有以下代码：

<p id="orderBy">
<script type="text/javascript"> 
  <!-- 
  // Array of day names
  var dayNames = ["Sunday","Monday","Tuesday","Wednesday",
                "Thursday","Friday","Saturday"];
  var nextWorkingDay = [ 1, 2, 3, 4, 5, 1, 1 ];
  var now = new Date();
  document.write("Order by 5pm today for dispatch on " +
                 dayNames[nextWorkingDay[now.getDay()]]);
  // -->
</script>
</p>

（根据Display tomorrow's name in javascript?）

例如，上面的代码输出如下：

Order by 5pm today for dispatch on Monday

如果因为任何原因禁用了javascript，我想要以下内容：

Order by 5pm for next working day dispatch

我该怎么做？

Answer 1

使用<noscript>：

<noscript>
    Order by 5pm for next working day dispatch
</noscript>

或将文本放入普通元素并使用JavaScript隐藏它。

Answer 2

<p id="orderBy">
<script type="text/javascript"> 
  <!-- 
  // Array of day names
  var dayNames = ["Sunday","Monday","Tuesday","Wednesday",
                "Thursday","Friday","Saturday"];
  var nextWorkingDay = [ 1, 2, 3, 4, 5, 1, 1 ];
  var now = new Date();
  document.write("Order by 5pm today for dispatch on " +
                 dayNames[nextWorkingDay[now.getDay()]]);
  // -->
</script>
<noscript>Order by 5pm for next working day dispatch</noscript>
</p>

如果Javascript不起作用，显示消息？
