求助：如何动态修改

[Sundyegg]

html如下:
<td id="T22" class="tx-l" onclick="GetClickInfo(this.id);" background="../img/cal_bg03.gif" height="49"><strong id="F22" class="tx-gray" ></strong></td>

我现在需要往<strong>之间添加text;同时还要修改<td>中的背景,我设了2个id,希望通过id选中<strong>和<td>但无法实现,希望诸位大虾指点一下,谢谢.

F22.innerHTML="sdfsdfsdfsdf"
T22.style.backgroundImage = "url(../img/cal_bg03.gif)"

用一个td的id就可以了
tdid.style.backgroundImage ="....";
tdid.innerHTML=strContent.bold();
