javascript - 将函数结果调用到 Web 文档

Question

所以我对 HTML 和编程完全陌生。我正在尝试完成学校作业的一道题，但遇到了很多麻烦。我已经完成了教程并用谷歌搜索了很多，但我似乎无法弄清楚。

我有这个功能:

function showDate() {
  thisDate = new Date();
  var thisWDay=thisDate.getDay();
  var thisDay=thisDate.getDate();
  var thisMonth=thisDate.getMonth();
  var thisYear=thisDate.getFullYear();
  var mName = new Array("January", "February", "March", "April", "May", 
    "June", "July", "August", "September", "October","November", "December");
  var wdName = new Array("Sunday", "Monday", "Tuesday", "Wednesday",
    "Thursday", "Friday", "Saturday");
  return wdName[thisWDay]+", "+mName[thisMonth]+" "+thisDay+", "+thisYear;
}

我需要在网络文档中显示此函数的输出。 我正在遵循教程，但它似乎不想工作。我知道我做错了什么。 这是我所拥有的:

<script type="text/javascript">
  function showDate();
  document.write("Today is <b> " + showDate() + "</b>");
</script>

我知道这可能非常简单，但任何朝正确方向的插入将不胜感激。

Answer 1

试试这个:

function showDate() {
  var thisDate = new Date();
  var thisWDay = thisDate.getDay();
  var thisDay = thisDate.getDate();
  var thisMonth = thisDate.getMonth();
  var thisYear = thisDate.getFullYear();
  var mName = new Array("January", "February", "March", "April", "May",
    "June", "July", "August", "September", "October", "November", "December");
  var wdName = new Array("Sunday", "Monday", "Tuesday", "Wednesday",
    "Thursday", "Friday", "Saturday");
  return wdName[thisWDay] + ", " + mName[thisMonth] + " " + thisDay + ", " + thisYear;
}

您将在函数调用后设置变量。

<script type="text/javascript">
var dt = showDate();
document.write("Today is <b> " + dt + "</b>");
</script>
