<script type="text/javascript">
        var hkey_key;
        var hkey_root = "HKEY_CURRENT_USER";
        var hkey_path = "\\Software\\Microsoft\\Internet Explorer\\PageSetup\\";

        //设置网页打印的页眉页脚为空
        function pagesetup_null() {
            try {
                var RegWsh = new ActiveXObject("WScript.Shell");
                hkey_key = "header";
                RegWsh.RegWrite(hkey_root + hkey_path + hkey_key, "");
                hkey_key = "footer";
                RegWsh.RegWrite(hkey_root + hkey_path + hkey_key, "");
            } catch (e) { }
        }

        //设置网页打印的页眉页脚为默认值
        function pagesetup_default() {

            } catch (e) { }
        }

        function doPrint() {
