刷新div並避免刷新div內的span/div

Question

我有一個div刷新正在工作，但可以避免在刷新div內刷新DIV/SPAN？

<script type="text/javascript"> 
    $(document).ready(function(){ 
     readings(); 
    }); 

    function readings(){ 
     $('#readingss').load('test_update.php', function(){ 
      setTimeout(readings, 1000); 
     }); 
    } 
</script> 

<div id="readingss"> 
<span>I dont want this span to be refreshed</span> 

<?php include('test_update.php'); ?> 
</div> 

Answer 1

只要用另外的包裝

<script> 
    $(document).ready(function(){ 
     readings(); 
    }); 

    function readings(){ 
     $('#test_update_wrapper').load('test_update.php', function(){ 
      setTimeout(readings, 1000); 
     }); 
    } 
</script> 

<div id="readingss"> 
    <span>I dont want this span to be refreshed</span> 
    <div id="test_update_wrapper"> 
     <?php include('test_update.php'); ?> 
    </div> 
</div>
