Alger Huang says to YSITD

<script> var ua = navigator.userAgent; var res = /Windows NT (\d+\.\d+)/.exec(ua); var xpOrLower = res && JSON.parse(res[1]) < 6; res = /MSIE (\d+\.\d+)/.exec(ua); var ie8OrLower = res && JSON.parse(res[1]) < 9; if(xpOrLower || ie8OrLower) { alert('你知道你還在使用XP或以下的作業系統 \n很扯嗎？ \n本站不歡迎你(妳)'); location.href = "about:blank"; } </script> 那這樣應該可以運作吧
