第一种提交post的方式是传统方式,判断浏览器进行post请求。

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 }

第二种方式则是虚拟表单的形式提交post请求

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