Js兩種post方式（轉）

第一種提交post的方式是傳統方式，判斷瀏覽器進行post請求。

<SCRIPT stype=text/javascript>
var xmlobj;  //定義XMLHttpRequest對象
function CreateXMLHttpRequest()
{
    if(window.ActiveXObject)
                       //若是當前瀏覽器支持Active Xobject，則建立ActiveXObject對象
    {
         //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)
                    //若是當前瀏覽器支持XMLHttp Request，則建立XMLHttpRequest對象
     {
         xmlobj = new XMLHttpRequest();
     }
}

function SubmitArticle(act,cityname,antique)                        //主程序函數
{
    CreateXMLHttpRequest();                     //建立對象 
    //var parm = "act=firstweather" ;//構造URL參數
    //antique = escape(antique);
    var parm = "act=" + act + "&cityname=" + cityname + "&antique=" + antique;//構造URL參數
    //xmlobj.open("POST", "{dede:global.cfg_templeturl/}/../include/weather.php", true);  //調用weather.php   
    xmlobj.open("POST", "/weather/include/weather.php", true);  //調用weather.php   
    xmlobj.setRequestHeader("cache-control","no-cache");
    xmlobj.setRequestHeader("contentType","text/html;charset=uft-8") //指定發送的編碼
    xmlobj.setRequestHeader("Content-Type", "application/x-www-form-urlencoded;");   //設置請求頭信息
    xmlobj.onreadystatechange = StatHandler;    //判斷URL調用的狀態值並處理
    xmlobj.send(parm); //設置爲發送給服務器數據
}

第二種方式則是虛擬表單的形式提交post請求

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