Question

我将其编程为在一段时间内显示一些图像。它应该从美国东部时间12月2日午夜到美国东部时间12月3日午夜显示。当我在12月2日的午夜检查时它正在工作，当我今天早上检查它已经死了。你能告诉我我的错误在哪里吗？

 <script type="text/javascript">

 var banner = new Array();
 banner[0] = "";
 banner[1] = "";
 banner[2] = "";
 banner[3] = "";
 banner[4] = "";
 banner[5] = "";
 banner[6] = "";
 var d = new Date();
 if ((d.getUTCDate() >= 2 && d.getUTCHours() >= 5) && (d.getUTCDate() <= 4 && d.getUTCHours() <=5)) 
 {
 document.write(banner [0], banner [1], banner [6], banner [5])}  
 else
 {
 document.write(banner [6], banner [5], banner [4], banner[1])
 }
 </script>

Answer 1

（d.getUTCDate（）＆gt; = 2＆amp;＆amp; d.getUTCHours（）＆gt; = 5）指的是12/2 5:00 am到12/3 0:00 am

（d.getUTCDate（）＆lt; = 4＆amp;＆amp; d.getUTCHours（）＆lt; = 5）指12/4 0:00 am到12/4 5:00 am

12/3 0:00 am到12/4 0:00失踪，

因此：

var banner = new Array();
 banner[0] = "0";
 banner[1] = "1";
 banner[2] = "2";
 banner[3] = "3";
 banner[4] = "4";
 banner[5] = "5";
 banner[6] = "6";
 var d = new Date();
 if ((d.getUTCDate() == 3)||(d.getUTCDate() >= 2 && d.getUTCHours() >= 5) && (d.getUTCDate() <= 4 && d.getUTCHours() <=5)) 
 {
 document.write(banner [0], banner [1], banner [6], banner [5])}  
 else
 {
     alert(d.getUTCHours())
 document.write(banner [6], banner [5], banner [4], banner[1])
 }

document.write特定时间
