当用户单击提交按钮时，我试图提醒一个值。我为两个选择标签都提供了“必需”属性，但它不起作用。

我想在用户提交按钮时提醒一个值。谁能告诉我哪里出错了？

代码：-

function openWindow() {
  var OR = document.getElementById("request").value;
  var SZ = document.getElementById("sites").value;
  var ORSZ = OR + SZ;
  alert(ORSZ); 
}

  
<select id="request" class="dropdownbox" required>
    <option value="">Select</option>
    <option value="ip">approve</option>
    <option value="url">reject</option>
  </select>
  
  <select id="sites" class="dropdownbox" required>
    <option value="">Select</option>
    <option value="cp">Account</option>
    <option value="sm">Demat</option>
    
  </select>

 <input type="button" onclick="openWindow()" value="Submit">
   

我有这样的两个数组.

 $array5 = json_decode('[{"time":"12:08 PM","md5":1201},{"time":"01:00 PM","md5":1121},{"day":"03:03 PM","md5":1401},{"time":"03:36 PM","md5":1334}] 
',true);
 $array6 = json_decode('[{"time":"12:08 PM","ips":20},{"time":"01:00 PM","ips":10},{"time":"03:02 PM","ips":12},{"time":"03:36 PM","ips":11}]', true);

使用array_merge_recursive的组合数组是:

[{"time":"12:08 PM","url":1201,"ips":20},{"time":"01:00 PM","url":1121,"ips":10},{"time":"03:03 PM","url":1401},{"time":"03:36 PM","url":1334,"ips":11},{"time":"03:02 PM","ips":12}] 

现在我想根据时间对这个数组进行排序.是否有可能根据时间对这个数组进行排序？
