Js两种post方式(转)

第一种提交post的方式是传统方式,判断浏览器进行post请求。

<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 }

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'});
