<input type=checkbox name=mm onclick="checkItem('All')"><br/>
<input type=checkbox name=mm onclick="checkItem('All')"><br/>
<input type=checkbox name=mm onclick="checkItem('All')"><br/>
<input type=checkbox name=mm onclick="checkItem('All')"><br/><br/>
<input type=checkbox name=All2 onclick="checkAll('mm2')">全选<br/>
<input type=checkbox name=mm2 onclick="checkItem('All2')"><br/>

<input type=checkbox name=mm2 onclick="checkItem('All2')"><br/>
<input type=checkbox name=mm2 onclick="checkItem('All2')"><br/>
<input type=checkbox name=mm2 onclick="checkItem('All2')"><br/>
</form>
<SCRIPT LANGUAGE="javascript">
function checkAll(str)
{
var a = document.getElementsByName(str);
var n = a.length;
for (var i=0; i<n; i++)
