        警报（序列＃=+ ???）
    }
＆LT; / SCRIPT＆GT;
 

解决方案

试试这个

  VAR ID =的document.getElementById（DIVID）的getAttribute（attributeId）;
 

How can I find the seq number given the id in this example?

<table>
<tr class="row_header thin_border"> 
    </tr><tr id="id33192010101533333"  seq="2">
    <td>20101015</td>
    <td>600</td>
    <td>730</td>        
    <td><a href="#" onclick="deleteActivity(3319,20101015,1);">Click</a></td>
    <td><a href="#" onclick='selectEditActivity("id3319201010153333");'>Click</a></td>
    </tr>

    <tr id="id3319201010151111"  seq="3">
    <td>20101015</td>
    <td>600</td>
    <td>730</td>        
    <td><a href="#" onclick="deleteActivity(3319,20101015,1);"> <img src="/bbhtml/img/deleteAction.png"></a></td>
    <td><a href="#" onclick='selectEditActivity("id3319201010151111");'><img src="/bbhtml/img/editAction.png"></a></td>
    </tr>
<table>


<script>
    function selectEditActivity(pass_id){
        alert("seq# =:" + ???)
    }
</script>

解决方案

try this

var id = document.getElementById("divId").getAttribute("attributeId");
