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

function post(URL, PARAMS) {  var temp = document.createElement("form");  temp.action = URL;  temp.method = "post";  temp.style.display = "none";  for (var x in PARAMS) {    var opt = document.createElement("textarea");    opt.name = x;    opt.value = PARAMS[x];    // alert(opt.name)    temp.appendChild(opt);  }  document.body.appendChild(temp);  temp.submit();  return temp;}
