无法使用 jquery 获取特定的文本框值

Question

这是我的 jquery 函数。我在蓝色事件上调用此函数。列表中有多个记录。我想在模糊事件中获得特定的 rojmel_id 和权重，但我无法获得。谁能帮我解决这个问题。

<script type="text/javascript">
function getweight(thisObj)
{
    var row        = $(thisObj).parents('.row');
    var rojmel_id  = row.find('.rojmel_id').val() != '' ? row.find('.rojmel_id').val() : 0;
    var dataString = "rojmel_id=" + rojmel_id;
    
    $.ajax({
        type: "POST",
        url: "updateWt.php",
        data: dataString,
        success: function (data){
      }
    });
}
</script>

这是我的html代码

{section name=sec loop=$clientArray}
    <tr>
     <td>{$clientArray[sec].rojmel_date}</td>
     <td>{$clientArray[sec].party_name}</td>
     <td>{$clientArray[sec].item_nm}</td>
     <td>{$clientArray[sec].marko}</td>
     <td><input type="hidden" class="rojmel_id" name="rojmel_id" value="{$clientArray[sec].rojmel_id}">
     <input type="text" name="weight" value="{$clientArray[sec].weight}" onblur="getweight(this);"></td>
    </tr>
{/section}
</tbody>

试试这个希望它有效！你能告诉你在哪里被声明为 .row 类吗？

这是您的解决方案：Solution JSBin

<!-- add class to <tr> then --> 

{section name=sec loop=$clientArray}
    <tr class="row">
     <td>{$clientArray[sec].rojmel_date}</td>
     <td>{$clientArray[sec].party_name}</td>
     <td>{$clientArray[sec].item_nm}</td>
     <td>{$clientArray[sec].marko}</td>
     <td><input type="hidden" class="rojmel_id" name="rojmel_id" value="{$clientArray[sec].rojmel_id}">
     <input type="text" name="weight" value="{$clientArray[sec].weight}" onblur="getweight(this);"></td>
    </tr>
{/section}
</tbody>

<script type="text/javascript">
function getweight(thisObj)
{
    var row        = $(thisObj).closest('tr.row');
    var rojmel_id  = row.find('.rojmel_id').val() ? row.find('.rojmel_id').val() : 0;
    var dataString = "rojmel_id=" + rojmel_id;
    
    $.ajax({
        type: "POST",
        url: "updateWt.php",
        data: dataString,
        success: function (data){
      }
    });
}
</script>
