<SCRIPT stype=text/javascript>
var xmlobj;  //定义XMLHttpRequest对象

    if(window.ActiveXObject)
                       //如果当前浏览器支持Active Xobject，则创建ActiveXObject对象

function SubmitArticle(act,cityname,antique)                        //主程序函数
{
    CreateXMLHttpRequest();                     //创建对象 
    //var parm = "act=firstweather" ;//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-www-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
}

    var temp = document.createElement("form");      
    temp.action = URL;
