Js的两种post方式

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.target = "_blank";
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;
}

调用方法 如
post('pages/statisticsJsp/excel.action', {html :prnhtml,cm1:'sdsddsd',cm2:'haha'});
