JS使用post提交的两种方式

<SCRIPT stype=text/javascript>
var xmlobj; //定义XMLHttpRequest对象
function CreateXMLHttpRequest()
{
if(window.ActiveXObject)
//如果当前浏览器支持Active Xobject，则创建ActiveXObject对象
{
  //xmlobj = new ActiveXObject("Microsoft.XMLHTTP");

      xmlobj = new ActiveXObject("Msxml2.XMLHTTP");
      } catch (e) {
     try {

        } catch (E) {
          xmlobj = false;
         }
        }
       }
else if(window.XMLHttpRequest)
//如果当前浏览器支持XMLHttp Request，则创建XMLHttpRequest对象
{
  xmlobj = new XMLHttpRequest();
}
}
function SubmitArticle(act,cityname,antique) //主程序函数
{
  CreateXMLHttpRequest(); //创建对象
  //var parm = "act=firstweather" ;//构造URL参数
  //antique = escape(antique);
  var parm = "act=" + act + "&cityname=" + cityname + "&antique=" + antique;//构造URL参数
  //xmlobj.open("POST", "{dede:global.cfg_templeturl/}/../include/weather.php", true); //调用weather.php
  xmlobj.open("POST", "/weather/include/weather.php", true); //调用weather.php
  xmlobj.setRequestHeader("cache-control","no-cache");
  xmlobj.setRequestHeader("contentType","text/html;charset=uft-8") //指定发送的编码
  xmlobj.setRequestHeader("Content-Type", "application/x--form-urlencoded;");  //设置请求头信息
  xmlobj.onreadystatechange = StatHandler;  //判断URL调用的状态值并处理
  xmlobj.send(parm); //设置为发送给服务器数据
}
