<SCRIPT LANGUAGE="JavaScript"><!--if (window.navigator.userAgent.indexOf("MSIE")>=1){//如果瀏覽器為IEsetActiveStyleSheet("default.css");}else{if (window.navigator.userAgent.indexOf("Firefox")>=1){//如果瀏覽器為FirefoxsetActiveStyleSheet("default2.css");}else{//如果瀏覽器為其他setActiveStyleSheet("newsky.css");}}function setActiveStyleSheet(title){ document.getElementsByTagName("link")[0].href="style/"+title; }//--></SCRIPT>

<SCRIPT LANGUAGE="JavaScript"><!--if (window.navigator.userAgent.indexOf("MSIE")>=1){var IE1024="";var IE800="";var IE1152="";var IEother="";ScreenWidth(IE1024,IE800,IE1152,IEother)}else{if (window.navigator.userAgent.indexOf("Firefox")>=1){//如果瀏覽器為Firefoxvar Firefox1024="";var Firefox800="";var Firefox1152="";var Firefoxother="";ScreenWidth(Firefox1024,Firefox800,Firefox1152,Firefoxother)}else{//如果瀏覽器為其他var Other1024="";var Other800="";var Other1152="";var Otherother="";ScreenWidth(Other1024,Other800,Other1152,Otherother)}}function ScreenWidth(CSS1,CSS2,CSS3,CSS4){if ((screen.width == 1024) && (screen.height == 768)){setActiveStyleSheet(CSS1);}else{if ((screen.width == 800) && (screen.height == 600)){setActiveStyleSheet(CSS2);}else{if ((screen.width == 1152) && (screen.height == 864)){setActiveStyleSheet(CSS3);}else{setActiveStyleSheet(CSS4);}}}}function setActiveStyleSheet(title){ document.getElementsByTagName("link")[0].href="style/"+title; }//--></SCRIPT>
