var HKEY_Root,HKEY_Path,HKEY_Key;
HKEY_Root="HKEY_CURRENT_USER";
HKEY_Path="\\Software\\Microsoft\\Internet Explorer\\PageSetup\\";
//设置网页列印的页眉页脚为空
function PageSetup_Null(){
try{
var Wsh=new ActiveXObject("WScript.Shell");
HKEY_Key="header";
Wsh.RegWrite(HKEY_Root+HKEY_Path+HKEY_Key,"");
HKEY_Key="footer";
Wsh.RegWrite(HKEY_Root+HKEY_Path+HKEY_Key,"");
}
catch(e){}
}
//设置网页列印的页眉页脚为预设值
function PageSetup_Default() {
try{
var Wsh=new ActiveXObject("WScript.Shell");
HKEY_Key="header";
Wsh.RegWrite(HKEY_Root+HKEY_Path+HKEY_Key,"&w&b页码,&p/&P");
HKEY_Key="footer";
Wsh.RegWrite(HKEY_Root+HKEY_Path+HKEY_Key,"&u&b&d");
