getting XMLHttpRequest cannot load (URL) Response for preflight is invalid (redirect)

here am trying to get reccurring events from calendar list for sharepoint Online app and there am using code as like
hostWebUrl = decodeURIComponent(manageQueryStringParameter('SPHostUrl'));
function GetListData() {
var webUrl = hostWebUrl;// = "http://server/sitewhereyourlistexists";
var listGuid = "{2000da75-8663-42d9-9999-ad855c54b4e0}"
// An XMLHttpRequest object is used to access the web service
var xhr = new XMLHttpRequest();
var url = webUrl + "/_vti_bin/Lists.asmx";
xhr.open("POST", url, true);
xhr.setRequestHeader("Content-Type", "text/xml; charset=utf-8");
xhr.setRequestHeader("SOAPAction", "http://schemas.microsoft.com/sharepoint/soap/GetListItems");
// The message body consists of an XML document
// with SOAP elements corresponding to the GetListItems method parameters
// i.e. listName, query, and queryOptions
var data = "<?xml version=\"1.0\" encoding=\"utf-8\"?>" +
"<soap:Envelope xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\">" +

// Here we define what code we want to run upon successfully getting the results
xhr.onreadystatechange = function () {
if (xhr.readyState == 4) {
if (xhr.status == 200) {
var doc = xhr.responseXML;
// grab all the "row" elements from the XML results
var rows = doc.getElementsByTagName("z:row");
var results = "Today's Schedule (" + rows.length + "):\n\n";
var events = {};
for (var i = 0, len = rows.length; i < len; i++) {
var id = rows[i].getAttribute("ows_FSObjType"); // prevent duplicates from appearing in results
if (!events[id]) {
events[id] = true;
var allDay = rows[i].getAttribute("ows_fAllDayEvent"),
title = rows[i].getAttribute("ows_Title"),
start = rows[i].getAttribute("ows_EventDate");
var index = start.indexOf(" ");
var date = start.substring(5, index) + "-" + start.substring(2, 4); // get the date in MM-dd-yyyy format
start = start.substring(index, index + 6); // get the start time in hh:mm format
var end = rows[i].getAttribute("ows_EndDate");
index = end.indexOf(" "); end = end.substring(index, index + 6); // get the end time in hh:mm format
results += date + " " + (allDay == "1" ? "All Day\t" : start + " to " + end) + " \t " + title + "\n";
}
}
alert(results);
} else {
alert("Error " + xhr.status);
}
}
};
// Finally, we actually kick off the query
xhr.send(data);
}
after calling this function in decument. ready section it is not retrieving any data but there is ine error which i can see in console of browser that is as below

You will click on the correct request in the left hand side panel, then select "Inspectors" in the right hand side top panel. Then choose between the different request and response options.

Get Particular node value in array from xml

I have one variable name as result in javascript Function.
The result variable's value is xml,
I need to form an Array with the opportunityid(which is highlighted in Image) values only.
how to get from the particular node value and form a array.?
I was used following Function,
function guid(){
var xml = "<?xml version='1.0' encoding='utf-8'?>" +
"<soap:Envelope xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\" xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\">" +
GenerateAuthenticationHeader() +
"<soap:Body>" +
"<RetrieveMultiple xmlns=\"http://schemas.microsoft.com/crm/2007/WebServices\">" +
"<query xmlns:q1=\"http://schemas.microsoft.com/crm/2006/Query\" xsi:type=\"q1:QueryExpression\">" +
"<q1:EntityName>opportunity </q1:EntityName>" +
"<q1:ColumnSet xsi:type='q1:ColumnSet'>" +
"<q1:Attributes>" +
"<q1:Attribute>opportunity id</q1:Attribute>" +
"</q1:Attributes>" +
"</q1:ColumnSet>" +
"<q1:Distinct>false</q1:Distinct>" +
"</query></RetrieveMultiple>" +
"</soap:Body></soap:Envelope>";
var xmlHttpRequest = new ActiveXObject("Msxml2.XMLHTTP");
xmlHttpRequest.Open("POST", "/mscrmservices/2007/CrmService.asmx", false);
xmlHttpRequest.setRequestHeader("SOAPAction", "http://schemas.microsoft.com/crm/2007/WebServices/RetrieveMultiple");
xmlHttpRequest.setRequestHeader("Content-Type", "text/xml; charset=utf-8");
xmlHttpRequest.setRequestHeader("Content-Length", xml.length);
xmlHttpRequest.send(xml);
var result = xmlHttpRequest.responseXML.xml;
var doc = new ActiveXObject("MSXML2.DOMDocument");
doc.async = false;
doc.loadXML(result);
}

As I can see the structure of your xml, it is as follows:
<soap:Body>
<RetrieveMultipleResponse>
<RetrieveMultipleResult>
<BusinessEntities>
<BusinessEntity>
<q1:oppourtunityid>
</q1:oppourtunityid>
</BusinessEntity>
</BusinessEntities>
</RetrieveMultipleResult>
</RetrieveMultipleResponse>
</soap:Body>
for this you can make use of DOM Element as follows:
var businessEntites = result.getElementsByTagName('BusinessEntity');
var oppidArr = [];
for(var i=0; i<businessEntities.length; i++)
{
var oppid = businessEntites.item(i).getElementsByTagName('q1:oppourtunityid').item(0).childNodes[0].nodeValue;
oppidArr[i] = oppid;
}

I guess, you should try below code, I have copied some of it from Mozilla's site as it's having best practice code with conditions :)
function guid(){
var xml = "<?xml version='1.0' encoding='utf-8'?>" +
"<soap:Envelope xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\" xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\">" +

"<soap:Body>" +
"<RetrieveMultiple xmlns=\"http://schemas.microsoft.com/crm/2007/WebServices\">" +
"<query xmlns:q1=\"http://schemas.microsoft.com/crm/2006/Query\" xsi:type=\"q1:QueryExpression\">" +
"<q1:EntityName>opportunity </q1:EntityName>" +
"<q1:ColumnSet xsi:type='q1:ColumnSet'>" +
"<q1:Attributes>" +
"<q1:Attribute>opportunity id</q1:Attribute>" +
"</q1:Attributes>" +
"</q1:ColumnSet>" +
"<q1:Distinct>false</q1:Distinct>" +
"</query></RetrieveMultiple>" +
"</soap:Body></soap:Envelope>";
var xmlHttpRequest;
if (window.XMLHttpRequest) { // Mozilla, Safari, ...
xmlHttpRequest = new XMLHttpRequest();
} else if (window.ActiveXObject) { // IE
try {
xmlHttpRequest = new ActiveXObject("Msxml2.XMLHTTP");
}
catch (e) {
try {
xmlHttpRequest = new ActiveXObject("Microsoft.XMLHTTP");
}
catch (e) {}
}
}
if (!xmlHttpRequest) {
alert('Giving up :( Cannot create an XMLHTTP instance');
return false;
}
xmlHttpRequest.onreadystatechange = getContents;
xmlHttpRequest.open("POST", "/mscrmservices/2007/CrmService.asmx", false);
xmlHttpRequest.setRequestHeader("SOAPAction", "http://schemas.microsoft.com/crm/2007/WebServices/RetrieveMultiple");
xmlHttpRequest.setRequestHeader("Content-Type", "text/xml; charset=utf-8");
xmlHttpRequest.setRequestHeader("Content-Length", xml.length);
xmlHttpRequest.send(xml);
function getContents() {
if (xmlHttpRequest.readyState === 4) {
if (xmlHttpRequest.status === 200) {
var xmldoc = xmlHttpRequest.responseXML;
var root_node = xmldoc.getElementsByTagName('q1:Attributes').item(0);
alert(root_node.firstChild.data);
} else {
alert('There was a problem with the request.');
}
}
}
}

Post web service from javascript

I'm triying to post webservice from javascript. I'am using this test webservice to post. But If I look in firebug I get following exception:
XML parsing error: syntax error Location: moz-nullprincipal:{9e8dc1d9-98d5-48f5-9106-5a19cb9ca7aa} Column: 1, Row: 1:
Reload the page to get source for: http://www.w3schools.com/webservices/tempconv...
^
My code is shown below:
var xmlhttp = new XMLHttpRequest();
xmlhttp.open('POST', 'http://www.w3schools.com/webservices/tempconvert.asmx', true);
// build SOAP request
var sr =
'<soapenv:Envelope' +
'xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" ' +
'xmlns:api="http://127.0.0.1/Integrics/Enswitch/API" ' +
'xmlns:xsd="http://www.w3.org/2001/XMLSchema" ' +
'xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">' +
'<soapenv:Body>' +
'<CelsiusToFahrenheit xmlns="http://tempuri.org/">' +
'<Celsius>44</Celsius>' +
'</CelsiusToFahrenheit>'+
'</soapenv:Body>' +
'</soapenv:Envelope>';
xmlhttp.onreadystatechange = function () {
if (xmlhttp.readyState == 4) {
if (xmlhttp.status == 200) {
alert('done use firebug to see response');
}
}
}
// Send the POST request
xmlhttp.setRequestHeader('Content-Type', 'text/xml');
xmlhttp.send(sr);
// send request
// ...
Have you any idea?

I found the problem.
I gave space near soapenv.
So it is look like now:
'<soapenv:Envelope' + ' ' +
'xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" ' +
'xmlns:api="http://127.0.0.1/Integrics/Enswitch/API" ' +
'xmlns:xsd="http://www.w3.org/2001/XMLSchema" ' +
'xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">' +
'<soapenv:Body>' +
'<CelsiusToFahrenheit xmlns="http://tempuri.org/">' +
'<Celsius>44</Celsius>' +
'</CelsiusToFahrenheit>'+
'</soapenv:Body>' +
'</soapenv:Envelope>';

Unable to pass JSONObject from JAVA Class to jsp

I have looked at this example but I am still unable to retrieve the JSON Object in the jsp. Here's the code in my MyCalendarController.java class:
public class MyCalendarController implements Controller{
public ModelAndView handleRequest(HttpServletRequest request,
HttpServletResponse response) throws Exception {
if("Add".equals(request.getParameter("action"))){
...
JSONObject jObj = new JSONObject();
jObj.put("test", "Success");
response.getWriter().write(jObj.toString());
...
}
return new ModelAndView("mycalendar", "model", myModel);
}
and here's how I'm trying to retrieve it in jsp but the alert always says 'undefined'
var queryString = "?action=Add";
queryString += "&t=" + title;
queryString += "&sDT=" + stDate + "T" + stHour + ":" + stMin + ":00";
queryString += "&eDT=" + eDate + "T" + eHour + ":" + eMin + ":00";
$.ajax({
type:"GET",
url: "mycalendar.htm" + queryString,
success: function(response){
alert(response.test);
}
});
Note: I am trying to create the JSON Object when the ajax call is made to the class from the jsp. I am new to ajax and javascript so must be doing something wrong... Please help!!!
In the above mentioned code, the response.responseText property is 'undefined'. But I tried it another way:
var ajaxRequest;
try{
ajaxRequest = new XMLHttpRequest();
}catch (e){
try{
ajaxRequest = new ActiveXObject("Msxml2.XMLHTTP");
}catch (e) {
try{
ajaxRequest = new ActiveXObject("Microsoft.XMLHTTP");
}catch (e){
alert("Your browser broke!");
return false;
}
}
}
ajaxRequest.onreadystatechange = function(){
if(ajaxRequest.readyState == 4){
alert(ajaxRequest.responseText);
alert("test: " + ajaxRequest.test);
}
}
var queryString = "?action=Add";
queryString += "&t=" + title;
queryString += "&sDT=" + stDate + "T" + stHour + ":" + stMin + ":00";
queryString += "&eDT=" + eDate + "T" + eHour + ":" + eMin + ":00";
ajaxRequest.open("GET", "mycalendar.htm" + queryString, true);
ajaxRequest.send(null);
This way I get the ajaxRequest.responseText but the alert("test: " + ajaxRequest.test); still shows undefined

var a = '<%=DropDown.returnList()%>';
var countryObj = JSON.parse(a);
var s = $('#selectCountry');
for(var val in countryObj)
{
$('<option />', {value: val, text: countryObj[val]}).appendTo(s);
}

Try to alert(response.responseText),I am not sure.

Multiple SOAP request using Javascript

All
I am using my SOAP API using java script.
this example explain how to send single soap request using js
var symbol = "MSFT";
var xmlhttp = new XMLHttpRequest();
xmlhttp.open("POST", "http://www.webservicex.net/stockquote.asmx?op=GetQuote",true);
xmlhttp.onreadystatechange=function() {
if (xmlhttp.readyState == 4) {
alert(xmlhttp.responseText);
// http://www.terracoder.com convert XML to JSON
var json = XMLObjectifier.xmlToJSON(xmlhttp.responseXML);
var result = json.Body[0].GetQuoteResponse[0].GetQuoteResult[0].Text;
// Result text is escaped XML string, convert string to XML object then convert to JSON object
json = XMLObjectifier.xmlToJSON(XMLObjectifier.textToXML(result));
alert(symbol + ' Stock Quote: $' + json.Stock[0].Last[0].Text);
}
}
xmlhttp.setRequestHeader("SOAPAction", "http://www.webserviceX.NET/GetQuote");
xmlhttp.setRequestHeader("Content-Type", "text/xml");
var xml = '<?xml version="1.0" encoding="utf-8"?>' +
'<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" ' +
'xmlns:xsd="http://www.w3.org/2001/XMLSchema" ' +
'xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">' +
'<soap:Body> ' +
'<GetQuote xmlns="http://www.webserviceX.NET/"> ' +
'<symbol>' + symbol + '</symbol> ' +
'</GetQuote> ' +
'</soap:Body> ' +
'</soap:Envelope>';
xmlhttp.send(xml);
// ...Include Google and Terracoder JS code here...
Now i want to send multiple soap request at a time (mean request more than one envelop).

As long as the third parameter in XMLHttpRequest.open is set to true the call will be asynchronous. So your should just be able to send a new one without much effort. You do need a new XMLHttpRequest object for it to work.
If you want to use the same callback you can just define it as a function and use this to work with the request object.
function soapCallback() {
if (this.readyState == 4) {
alert(this.responseText);
// http://www.terracoder.com convert XML to JSON
var json = XMLObjectifier.xmlToJSON(this.responseXML);
var result = json.Body[0].GetQuoteResponse[0].GetQuoteResult[0].Text;
// Result text is escaped XML string, convert string to XML object then convert to JSON object
json = XMLObjectifier.xmlToJSON(XMLObjectifier.textToXML(result));
alert(symbol + ' Stock Quote: $' + json.Stock[0].Last[0].Text);
}
}
var symbol = "MSFT";
var xml = '<?xml version="1.0" encoding="utf-8"?>' +
'<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" ' +
'xmlns:xsd="http://www.w3.org/2001/XMLSchema" ' +
'xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">' +
'<soap:Body> ' +
'<GetQuote xmlns="http://www.webserviceX.NET/"> ' +
'<symbol>' + symbol + '</symbol> ' +
'</GetQuote> ' +
'</soap:Body> ' +
'</soap:Envelope>';
var xmlhttp1 = new XMLHttpRequest();
xmlhttp1.open("POST", "http://www.webservicex.net/stockquote.asmx?op=GetQuote",true);
xmlhttp1.onreadystatechange=soapCallback;
xmlhttp1.setRequestHeader("SOAPAction", "http://www.webserviceX.NET/GetQuote");
xmlhttp1.setRequestHeader("Content-Type", "text/xml");
xmlhttp1.send(xml);
var xmlhttp2 = new XMLHttpRequest();
xmlhttp2.open("POST", "http://www.webservicex.net/stockquote.asmx?op=GetQuote",true);
xmlhttp2.onreadystatechange=soapCallback;
xmlhttp2.setRequestHeader("SOAPAction", "http://www.webserviceX.NET/GetQuote");
xmlhttp2.setRequestHeader("Content-Type", "text/xml");
xmlhttp2.send(xml);
