我试图获取当前行ID ID编辑图标

请查找TableWidgets文件，如下面的链接所示 https://drive.google.com/folderview?id=0BwtwIV52Ve6kRFBJdkFCY0NvQUk&usp=sharing

的index.php

 <script type="text/javascript">
$(document).ready(function() { 
    $('#list-grid table td div [action=tw-edit]').click(function(event) {
        var rowId =$(this).closest("div.list-grid").attr("id");
        alert (rowIdx);

    });     
});
</script>
 <?php $this->beginWidget('application.widgets.TableWidget', 
        array(      
         'dataProvider'=>$dataProvider,
         'fixedHead' => true,
         'id' => 'list-grid',                   
        )); 
 ?> 
<?php $this->endWidget(); ?>
