由于php中的js文件，提交按钮无法工作

I从js创建了自动完成列表框。我下载了这个js。

但是由于我的代码中的js实现。。。

我的保存和搜索按钮不工作。。。

但是当我评论这个js文件时。。。提交按钮工作正常

但是这个js对于我将listbox作为自动完成文本框也是必要的。。。

请告诉我这本书要改什么。。使按钮和列表框都工作。

我的保存按钮代码

<?php
if($_POST && isset($_POST['submit']))
{}
?>

下面是我的列表框

<select class="special-flexselect"  id="society" name="society" tabindex="5" >                      
     <option  value="" ></option>
      <?php foreach ($society as $soc){ ?>  
 <option  value="<?php echo $soc["society"]; ?>"><?php echo $soc["society"]; ?></option>
  <?php }?>
                            </select>

下面是我的js代码
