jquery – 获取单选按钮的文本而不是值

<SCRIPT type="text/javascript">
    $(function() 
    {   

        var ids = new Array();

        for(var i = 0; i < <?PHP  echo $numR; ?>; i++)
        {
            ids.push(i);
        }

        function f(place) {
           $("#prod_btn" + place).click(function () {

                var combine = "prod_title" + place;
                var userNameVal = $("#" + combine).val();
                var radVal = $('input:radio[name=prod_rad' + place +']:checked').val();
                $.post( 
                 "cart.PHP",{ uval : userNameVal,rval : radVal },function(data) {
                    $('#show_search2').html(data);
                 }

              );


           });
        }

        for (var i=0; i<ids.length; i++) 
        {

           f(ids[i]);
        }

    });
</SCRIPT>

这是HTML

while ($i < $numR)
{
$prod_image_id = 'prod_image'.$i.'';
$prod_title_id = 'prod_title'.$i.'';
$prod_priceM_id = 'prod_priceM'.$i.'';
$prod_priceA_id = 'prod_priceA'.$i.'';
$prod_priceH_id = 'prod_priceH'.$i.'';
$prod_priceP_id = 'prod_priceP'.$i.'';
$prod_rad_id = 'prod_rad'.$i.'';
$prod_btn_id = 'prod_btn'.$i.'';

$prodID         = MysqL_result($result,$i,"astm_product_ID");
$prodName       = MysqL_result($result,"astm_product_name");
$prodPic        = MysqL_result($result,"astm_product_image");

$mPrice         = MysqL_result($result,"astm_mill_finish_price");
$aPrice         = MysqL_result($result,"astm_anodised_price");
$hPrice         = MysqL_result($result,"astm_hanolok_price");
$pPrice         = MysqL_result($result,"astm_powdercoat_price");

    echo "<li>";
    echo "<DIV id='prod_container'>";
    echo "<DIV id = 'fp1'><center><IMG class = 'imagesize' src='images/fp1.png' id = '$prod_image_id'/></center></DIV>";
    echo "<DIV><p>$prodName<p><input type = 'hidden' id = '$prod_title_id' value = '$prodName' /></DIV>";
    echo "<DIV><input type='radio' value='$mPrice' name='$prod_rad_id'>Mill Finish - PHP $mPrice</input></DIV>";
    echo "<DIV><input type='radio' value='$aPrice' name='$prod_rad_id'>Anodised - PHP $aPrice</input></DIV>";
    echo "<DIV><input type='radio' value='$hPrice' name='$prod_rad_id'>Hanolok - PHP $hPrice</DIV>";
    echo "<DIV><input type='radio' value='$pPrice' name='$prod_rad_id'>Powder Coat - PHP $pPrice</input></DIV>";
    echo "<DIV><button type='button' id = '$prod_btn_id' onClick = 'fg_popup_form(\"fg_formContainer\",\"fg_form_InnerContainer\",\"fg_backgroundpopup\");'>Add to Cart</button></DIV>";
    echo "</DIV>";
    echo "</li>";

$i++;
}

js只是获取所选单选按钮的值和产品名称.它工作正常.我的问题是我还想获得所选单选按钮的文本. “.text()”对我不起作用,我不知道为什么.帮帮我谢谢！
