解釋:

 

var IE1024="";
var IE800="";
var IE1152="";
var IEother="";


引號裡面分別填寫,使用者使用IE的時候並且解析度為1024*768,800*600,1152*864要使用的css檔案名稱.

 

var Firefox1024="";
var Firefox800="";
var Firefox1152="";
var Firefoxother="";


引號裡面分別填寫,使用者使用FF的時候並且解析度為1024*768,800*600,1152*864要使用的css檔案名稱.

 

var Other1024="";
var Other800="";
var Other1152="";
var Otherother="";


引號裡面分別填寫,使用者使用其他瀏覽器的時候並且解析度為1024*768,800*600,1152*864要使用的css檔案名稱.

不判斷解析度,只判斷瀏覽器

應E.Qiang提議,編如下代碼。實現根據瀏覽器類型自動調用不同CSS。

代碼:


<SCRIPT LANGUAGE="javascript">
<!--
if (window.navigator.userAgent.indexOf("MSIE")>=1)
{
file://如果瀏覽器為IE
setActiveStyleSheet("default.css");
}else{
if (window.navigator.userAgent.indexOf("Firefox")>=1)
{
file://如果瀏覽器為Firefox
setActiveStyleSheet("default2.css");
}else{
file://如果瀏覽器為其他
setActiveStyleSheet("newsky.css");
}

function setActiveStyleSheet(title){ 
document.getElementsByTagName("link")[0].href="style/"+title; 
}
file://-->
</SCRIPT>

解釋:

如果瀏覽器為IE,則調用default.css

如果瀏覽器為Firefox,則調用default2.css

如果瀏覽器為其他,則調用newsky.css

用法:放在<head></head>中即可。
