Question

如果子级具有“PageText_L657n”类，则尝试将类添加到具有“pricecolor”类的字体标记。

    <table width="100%" cellspacing="0" cellpadding="0">
  <tbody>
    <tr>
      <td width="64%" valign="top"> Stock Item (Usually Ships Within 24 Hours) <br>
        <font class="text colors_text"><span class="PageText_L483n"><b><span class="PageText_L334n">MSRP</span>: $4,895.00</b> </span></font><br>
        <b><font class="pricecolor colors_productprice"><span class="PageText_L483n"><font class="text colors_text"><b>Regular Price: </b></font> $1,872.34 </span></font></b><br>
        <br>
      <a class="pricecolor colors_productprice"><span class="PageText_L657n"><span style="font-size: 16px; color: rgb(0, 0, 255);">Click To Get Today's Special Price!</span></a></td>
      <td width="36%" align="right"></td>
    </tr>
  </tbody>
</table>

<script>
$(function(){
$(".pricecolor").child().hasClass("PageText_L657n").addClass("ice1");
});

</script>
