How can I change the css class of each th tag from “T” to “ST”? And —

I have an iframe with the following HTML which is empty when I load a page.

[code=html]<iframe id=”A”></iframe> [/code]

I am loading the iframe(A) with the following code using JavaScript:

[CODE]
document.getElementById(A).src = ‘https://adms.lifemark.ca/Apps/app_quickadd_frame.jsp?appid=102946&oppid=’+Current;[/CODE]

After loading the iframe(A) it creates 10 iframe within iframe(A).Each new iframe has 1 table and many th tag.

I have the following question:
1) How can I change the css class of each th tag from “T” to “ST” using Jquery?
2) How can I assign one more function(PI) to the following button within the last table of iframe(A) using Jquery? This function should execute after first fuction(S?.

[code=html]
<table>
<tbody>
<tr>
<td class=”Submit”>
<input type=”Button” value=”Submit” onclick=”sb()” style=”width:200px”>
</td>
</tr>
</tbody>
</table>[/code]

3) How can I enable a checkbox(id=”111″) in all the frames except first frame and assign function(CopyPrevious) to the checkbox using Jquery?

Thanks
