Yesterday, I encountered an abnormal option display in the project. The screenshot is as follows:

The effect after using css control in Firefox

css does not work in chrome and IE

Code:

<div class="controls">         <select name="ksname" id="ksname">             <?php                 while (!!$rowDK = fetchAssoc($resultDK))                  {             ?>             <optgroup label="<?php echo $rowDK['name']; ?>">               <?php                $resultKS = queryDB("select table_dake.id,table_keshi.sid,table_keshi.name from table_dake,table_keshi where table_dake.name='{$rowDK['name']}' and table_keshi.sid=table_dake.id");                 while(!!$rowKS = fetchAssoc($resultKS))                 {               ?>                 <option  value ="<?php echo $rowKS['name']; ?>"><?php echo $rowKS['name']; ?></option>                                  <?php                     </optgroup>                   }                 }                 free($resultDK);                 free($resultKS);             ?>         </select>     </div>

After reading the source code, there are indeed not many styles, but there is an extra after each option. After looking back at the code, I realized that I wrote in the inner loop. According to my The logic should be placed in the outer loop. After adjustment, everything is normal.

So, there is another way to debug the code: view the original code
