Answer 1

function closeDIV() { 
document.getElementById("lbplocation").style.display="none"; 
} 
/firefox/i.test(navigator.userAgent) && setTimeout("closeDIV()",15000); 

Answer 2

我搜到个JS 这么修改的 能用：<script> 
function closeDIV() 
{
if (navigator.userAgent.indexOf("MSIE") != -1) { 
document.getElementById("lbplocation").style.display="block"; 
} else { 
document.getElementById("lbplocation").style.display="none"; 
} 
}
setTimeout("closeDIV()",14000); //一万毫秒后关闭 
</script>
