看看下面代码,提交表单quickevent，ajax处理返回的xml数据，在createJSEvent中处理，duty[0].firstChild.nodeValue总报错说缺少对象，怀疑是不是返回的根本就不是xml，大伙帮找下问题
<form name=quickevent action=javascript:submite();>
<input type=hidden name=dd>
<input type=hidden name=sd>
<input type=hidden name=desc>
<input type=hidden name=title>
<input type=hidden name=users>
<input type=hidden name=busy>
<input type=hidden name=allday>
</form>

function submite(){
var filename= 'test.do?action=create ';
importXML(filename, 'createJSEvent ');
}


function createJSEvent(xml){
var duty=xml.getElementsByTagName( "duty ");
var xmlRe = duty[0].firstChild.nodeValue;
alert(xmlRe);
}


var rq = new Array();

function importXML(_1,_2) {
return handleRequest(_1,_2);
}
function handleRequest( rurl, fallback) {
rurl += ( ( rurl.indexOf( '? ') + 1 ) ? '& ' : '? ' ) + ( new Date() ).getTime();
if( window.XMLHttpRequest )
return handleNS(rurl,fallback);
if( !navigator.__ice_version && window.ActiveXObject )
return handleIE(rurl,fallback);
if( document.createElement && document.childNodes )
return handleOthers(rurl,fallback);
return false;
}

function handleIE(u,f) {
try {
try {
var xmlObject = new ActiveXObject( 'Microsoft.XMLDOM ' );
} catch(e) {
var xmlObject = new ActiveXObject( 'Msxml2.XMLHTTP ' );
}
rt = rq.length
rq[rt] = xmlObject;
rq[rt].onreadystatechange = new Function( 'if( rq[ '+rt+ '].readyState == 4 ) { '+f+ '(rq[ '+rt+ ']); rq[ '+rt+ ']=null; } ' );
rq[rt].load(u);
return true;
} catch(e) {}
}

//action代码示例
public ActionForward create(ActionMapping actionMapping,
ActionForm actionForm, HttpServletRequest request,
HttpServletResponse response) {
StringBuffer sb = new StringBuffer( " <duty> ");
sb.append( " <id> 8a814a8c1153e4b3011153f27c920002 </id> ")
sb.append( " <users> ");
sb.append( " <user> ");
sb.append( " <userid> 402882880f5760bf010f57783cd20002 </userid> <username> 李杰 </username> ");
sb.append( " </user> ");
sb.append( " </users> ");
sb.append( " <date> 2007-03-15 </date> ");
sb.append( " <starttime> 03:00 PM </starttime> ");
sb.append( " <endtime> 03:30 PM </endtime> ");
sb.append( " <allday> off </allday> ");
sb.append( " <description> </description> ");
sb.append( " </duty> ");

response.setContentType( "text/xml ");
response.getWriter().write(dutyXML);

return null;
}
