不工作在ie，歌劇如何修復？

Question

我該如何修復它以在ie或opera瀏覽器中工作？

另外我想在這個div的可見性上添加一些延遲？像30秒，詢問的onclick你的鏈接將在30秒

apear定時器看到這裏的行動 http://www.symbianhome.com/ibibo-ibrowser-free-download-v2

感謝

代碼工作在Opera。對於延遲演出，使用此。它也會在點擊後禁用按鈕。

<script> 
var remaining=30; 
function countDown() { 
    remaining--; //decrease remaining 
    document.getElementById('counter').innerText = remaining; //update display 
    if (remaining > 0) { //more remains? 
    window.setTimeout(countDown, 1000); //yes. wait again 
    } else { //no. show the content 
    document.getElementById('divId').style.visibility = 'visible'; 
    } 
} 
function delayShow(ele) { 
    ele.disabled = true; 
    document.getElementById('counter').innerText = remaining; //show it 
    window.setTimeout(countDown, 1000); //wait for 1 second then call countDown 
} 
</script> 

<div id="divId" style="visibility:hidden">Content!</div> 

<button onclick="delayShow(this)">DOWNLOAD</button> <span id="counter"></span>
