我这么写代码能够正确执行..但是IE左下会出错说:
报错: 'cells.0.getElementsByTagName(...).0.innerHTML ' 为空或不是对象

<script language=javascript>

function showzd()
{
var textflie = document.getElementById( "zd ").rows;
var length=textflie.length;
for(var i=1;i <length;i++)
{
var tTime = textflie[i].cells[0].getElementsByTagName( 'span ')[0].innerHTML;


if ( tTime == "主队 " )
{
if (textflie[i].style.display == "none " ) {textflie[i].style.display = "block " } else {textflie[i].style.display = "none " }

}

}
}
</script>
<table width= "610 " border= "0 " cellpadding= "0 " cellspacing= "1 " bgcolor= "#006699 " class= "font12bcenter " id= "zd ">
<tr>
<td height= "20 " onclick= "showzd(); "> <div class= "STYLE1 " > 主队往绩 </div> </td>
