Ajax post数据在服务器端怎么取。
Ajax   post数据在服务器端怎么取。
get取没问题，post没取到

  var   url= "WebForm1.aspx ";
                        xmlHttp.open( "POST ",url,true);
                        xmlHttp.onreadystatechange   =   writeNewMessage;
                        xmlHttp.send( "action=send "+
                                                  "&lastId= "+lastId);

------解决方案--------------------
Request.Form[ "action "]

Request.Form[ "lastId "]
------解决方案--------------------
xmlHttp.send( "action=send "+
"&lastId= "+lastId);
把这个，接在URL里
xmlHttp.send( " ");试试，如果还有问题，说明是JS代码问题
