สอบถามคะ ถ้าจะกำหนด javascript เปิดหน้าใหม่(New Tab) จะต้องกำหนดอย่างไรคะ

function flightSearch(p_form){
		var full_month_de = p_form.departMonth.value.split('/');
		var year_de = full_month_de[1];
		var month_de = full_month_de[0];

		var full_month_re = p_form.returnMonth.value.split('/');
		var year_re = full_month_re[1];
		var month_re = full_month_re[0];
		
		var p_departDate = p_form.departDay.value+'/'+month_de+'/'+year_de;
		var p_returnDate = p_form.returnDay.value+'/'+month_re+'/'+year_re;
		var p_roundTrip;
		
		for (var i=0; i < p_form.roundTrip.length; i++){
			if (p_form.roundTrip[i].checked){
				p_roundTrip = p_form.roundTrip[i].value;
			}
		}

//		var record = {
//			roundTrip : p_roundTrip,
//			routeFrom : p_form.routeFrom.value,
//			routeTo : p_form.routeTo.value,
//			departDate : p_departDate,
//			returnDate : p_returnDate,
//			guest : p_form.guest.value,
//			child : p_form.child.value,
//			infant : p_form.infant.value
//		};
//		window.open("http://192.168.2.31/ebooking/index.php?c=ebooking&search={roundTrip:'"+p_roundTrip+"',routeFrom:'"+p_form.routeFrom.value+"',routeTo:'"+p_form.routeTo.value+"',departDate:'"+p_departDate+"',returnDate:'"+p_returnDate+"',guest:"+p_form.guest.value+",child:"+p_form.child.value+",infant:"+p_form.infant.value+"}");
		window.location.href = "http://"+window.location.host+"/ebooking/index.php?c=ebooking&search={roundTrip:'"+p_roundTrip+"',routeFrom:'"+p_form.routeFrom.value+"',routeTo:'"+p_form.routeTo.value+"',departDate:'"+p_departDate+"',returnDate:'"+p_returnDate+"',guest:"+p_form.guest.value+",child:"+p_form.child.value+",infant:"+p_form.infant.value+"}";
		return false;
