如何替換基於移動設備的useragent的超鏈接

我有以下html檢測useragent是否來自黑莓設備。我想知道如何用一個特定的設備來替換下載url，也就是說，如果他的設備是9800，我想引導用戶下載9800設備。請任何人都可以幫忙嗎？如何替換基於移動設備的useragent的超鏈接

<!DOCTYPE html> 
<html> 
<body> 
<script type="text/javascript"> 
var ua = navigator.userAgent; 
document.write("BB OS Version :: " + ua); 
if (ua.indexOf("BlackBerry") >= 0) { 
    if (ua.indexOf("Version/") >= 0) { // ***User Agent in BlackBerry 6 and BlackBerry 7 
     Verposition = ua.indexOf("Version/") + 8; 
     TotLenght = ua.length; 
     document.write("BB OS Version :: " + ua.substring(Verposition, Verposition + 3)); 
    } 
    else {// ***User Agent in BlackBerry Device Software 4.2 to 5.0 
     var SplitUA = ua.split("/"); 
     document.write("BB OS Version :: " + SplitUA[1].substring(0, 3)); 
    } 
} 
</script>

如果你只是想爲你的下載按鈕的具體樣式，則只需添加一個類，如果它是一個黑莓手機，並把它拿走，如果事實並非如此。
