我想显示昨天的日期和日期。
今天日期的脚本:
<script type="text/javascript">
<!--
// Array of day names
var dayNames = new Array("Sunday","Monday","Tuesday","Wednesday","Thursday","Friday","Saturday");
// Array of month Names
var monthNames = new Array("January","February","March","April","May","June","July","August","September","October","November","December");
var now = new Date();
document.write(dayNames[now.getDay()] + ", " +
monthNames[now.getMonth()] + " " +
now.getDate() + ", " + now.getFullYear());
// -->
</script>
我知道添加 -1 会更改日期/年份，但它不会成功更改星期/月份的日期，因为我们已在数组中列出了日期/月份，因此星期日和之前没有任何内容一月之前没有任何事情。
如何显示昨天/几天前的日期，确保日期和月份会发生变化？
最佳答案
你可以尝试这个:参见 DEMO
dayNames[now.getDay()==0?6:now.getDay()-1]
编辑:
将 setDate 设置为昨天: Demo
now.setDate(now.getDate()-1); // set yesterday for now
