用request.getParameter("")得不到值

lifei515 2011-12-21 10:20:04

document.getElementById('fm').action="<%=basePath%>/mobilenetinterface?mobile_net_type=runPage&jtq=onlyrecord&urlKey=" + i + "&ProjectID=3&IsModel=false&jtr=" + jtr + "&jtrr=";
document.getElementById('fm').submit();

servlet用这种提交，用request.getParameter("mobile_net_type")后台获取不到值，为null
请各位指教
