jquery操作html的object标签的问题

  <object id="FlashID" classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" width="657" height="499">

    <param name="movie" id="paramobject1" value="aa.swf?userName=" />

    <param name="quality" value="high" />

    <param name="wmode" value="transparent" />

    <param name="swfversion" value="6.0.65.0" />

     <!--[if !IE]>-->

    <object type="application/x-shockwave-flash" id="paramobject2" data="aa.swf?userName=" width="657" height="499">

      <!--<![endif]-->

      <param name="quality" value="high" />

      <param name="wmode" value="transparent" />

      <param name="swfversion" value="6.0.65.0" />  

    </object>

    <!--<![endif]-->

  </object>

$(document).ready(function(){

    $.ajax({

        url: "../getURL",

        dataType: "json",

        type: "POST",

        

        error: function (XMLHttpRequest, textStatus, errorThrown) {

            

        },

        

        success: function(result) {

           $('#paramobject1').val(result);

//怎么修改paramobject2的data属性？

        }

    })

})

------解决方案--------------------
$('#paramobject2').attr('data','某个值');
