PHP if语句中的Jquery

Question

Need help to put some jquery function inside if statement . I want to hide my div when data from database is empty . I've done like this , and nothing happened.

                            <script>
                                $(document).ready(function () {
                                    $( '.table-wrapper').css("display","none");
                                });
                            </script>                       <===update

                    <?php }else{ ?>
                        <?php foreach($all_data->result() as $data){ ?>
                            <tr> 
                                <td><?php echo $data->id_history;?></td>
                                <td><?=$data->id_admin;?></td>
                                <td><?=$data->ipc;?></td>
                                <td><?=$data->task_date;?></td>
                                <td><?=$data->task_time;?></td>
                                <?php if ($data->id_task == 1){ ?>
                                    <td>Login Site</td>  
                                <?php }else{ ?>
                                    <td>Logout Site</td>
                                <?php } ?>
                                <td>-</td>
                            </tr>
                        <?php } ?>  
                    <?php } ?>

Is it possible to put some jquery inside php ??

Answer 1

Try this one

<!--Always generate table-->
<div class='table-wrapper'>
    <table>
       <?php foreach($all_data->result() as $data){ ?>
          <tr> 
         <td><?php echo $data->id_history;?></td>
         <td><?=$data->id_admin;?></td>
         <td><?=$data->ipc;?></td>
         <td><?=$data->task_date;?></td>
         <td><?=$data->task_time;?></td>
         <?php if ($data->id_task == 1){ ?>
            <td>Login Site</td>  
         <?php }else{ ?>
            <td>Logout Site</td>
         <?php } ?>
         <td>-</td>
     </tr>
<?php } ?>  
</table>
</div>

<!-- Hide Wrapper if no data -->
<script>
var div = $(".table-wrapper");
if(div.html() == "<table></table>") {
   div.css("display","none");
}
</script>
