var http;

function test(element){

var trid=element.id;

var trvalue=element.value;

if(window.ActiveXObject){

try {

alert("ie");

http= new ActiveXObject("Msxml2.XMLHTTP") ;

} catch (e) {

try {

alert("ie2");

http= new ActiveXObject("Microsoft.XMLHTTP") ;

} catch (e2) {

;

}

}

} else if(window.XMLHttpRequest){

http= new XMLHttpRequest() ;

}

var url = "${it.rootUrl}controller/post";

var str="id="+trid+"&name="+trvalue;

http.onreadystatechange = callback;

http.open("POST",url,true);

http.setRequestHeader("Content-length",str.length);

http.setRequestHeader("Content-Type","application/x-www-form-urlencoded");

http.send(str);

}

public void doPost(StaplerRequest req, StaplerResponse rsp)

throws ServletException, IOException, InterruptedException {

String result=null;

int count = Hudson.getInstance().getComputers().length;

//    int c = 1;

String url = Hudson.getInstance().getRootUrl();

String[][] slave = getipmac();

//        String temp=null;

System.out.println(    "------------header---"+req.getHeader("id"));

System.out.println(    req.getDateHeader("id"));

int c= Integer.parseInt(req.getParameter("id"));

String temp=req.getParameter("name");

System.out.println("---------------temp---"+temp);

System.out.println("------c-----"+c);

......

rsp.setContentType("text/html;charset=utf-8");

PrintWriter out=rsp.getWriter();

out.write(result); //将信息写入response

out.flush();

out.close();

//    rsp.forwardToPreviousPage(req);

}

}

错误信息在   int c= Integer.parseInt(req.getParameter("id"));

没有获取到参数

应该如何传参数？
