使用prototype.js写的读取RSS的例子

使用prototype.js写的读取RSS的例子，代码如下:
< html>
< head>
< title>ReadRSS< /title>
< script src="common/prototype.js">< /script>
< script>
function send_Request(url)
{
    var request_url =url;//跨域的话,需要写一个代理.
    var request_pars = null;
    var myAjax = new Ajax.Request(
        request_url,
        {
            method:'get',
            parameters:request_pars,
            asynchronous:true,       //true---异步;false---同步.默认为true
            onComplete:processRequest
        }    
    );
}
 
function processRequest(XML_Http_Request){
    var results = XML_Http_Request.responseXML;
    var title = null;
    var item = null;
    var link = null;
    var ccc = results.getElementsByTagName("channel");
    var headtitle = ccc[0].getElementsByTagName("title")[0].firstChild.nodeValue;
    var headlink = ccc[0].getElementsByTagName("link")[0].firstChild.nodeValue;
    var cell = document.createElement("div");
    cell.innerHTML = "< h1>< a href="+headlink+" target=_blank>"+headtitle+"< /a>< /h1>< br>";
    $("result").appendChild(cell);
    var items = results.getElementsByTagName("item");
    for(var i = 0; i <  items.length; i++) {
        item = items[i];
        link=item.getElementsByTagName("link")[0].firstChild.nodeValue;
        title = item.getElementsByTagName("title")[0].firstChild.nodeValue;
        var cell = document.createElement("div");
        cell.innerHTML = "< li>< a href="+link+" target=_blank>"+title+"< /a>< /li>< br>";
        $("result").appendChild(cell);
    }
}
 
var myGlobalHandlers = {
    onCreate:function (){
        Element.show('systemWorking');
    },
    onComplete:function (){
        if(Ajax.activeRequestCount == 0){
            Element.hide('systemWorking');
        }
    }
};
Ajax.Responders.register(myGlobalHandlers);
