使用prototype.js写的读取RSS的例子

prototype Ajax XML

<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); 
</script> 
</head> 
<body onLoad="javascript:send_Request('http://esoft.bokee.com/rss2.xml');"> 
<div id='systemWorking'>Loading...</div> 
<div id="result"></div> 
</body> 
</html>
