What is the simplest SOAP example using Javascript?
To be as useful as possible, the answer should:
Be functional (in other words actually work)
Send at least one parameter that can be set elsewhere in the code
Process at least one result value that can be read elsewhere in the code
Work with most modern browser versions
Be as clear and as short as possible, without using an external library
This is the simplest JavaScript SOAP Client I can create.

There are many quirks in the way browsers handle XMLHttpRequest, this JS code will work across all browsers:
https://github.com/ilinsky/xmlhttprequest
This JS code converts XML into easy to use JavaScript objects:
http://www.terracoder.com/index.php/xml-objectifier
The JS code above can be included in the page to meet your no external library requirement.
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" ' +

xmlhttp.send(xml);

Two other options:
JavaScript SOAP client:
http://www.guru4.net/articoli/javascript-soap-client/en/
Generate JavaScript from a WSDL:
https://cwiki.apache.org/confluence/display/CXF20DOC/WSDL+to+Javascript
This cannot be done with straight JavaScript unless the web service is on the same domain as your page. Edit: In 2008 and in IE<10 this cannot be done with straight javascript unless the service is on the same domain as your page.
If the web service is on another domain [and you have to support IE<10] then you will have to use a proxy page on your own domain that will retrieve the results and return them to you. If you do not need old IE support then you need to add CORS support to your service. In either case, you should use something like the lib that timyates suggested because you do not want to have to parse the results yourself.
If the web service is on your own domain then don't use SOAP. There is no good reason to do so. If the web service is on your own domain then modify it so that it can return JSON and save yourself the trouble of dealing with all the hassles that come with SOAP.
Short answer is: Don't make SOAP requests from javascript. Use a web service to request data from another domain, and if you do that then parse the results on the server-side and return them in a js friendly form.
You can use the jquery.soap plugin to do the work for you.
This script uses $.ajax to send a SOAPEnvelope. It can take XML DOM, XML string or JSON as input and the response can be returned as either XML DOM, XML string or JSON too.
Example usage from the site:
$.soap({
url: 'http://my.server.com/soapservices/',
method: 'helloWorld',
data: {
name: 'Remy Blom',
msg: 'Hi!'
},
success: function (soapResponse) {
// do stuff with soapResponse
// if you want to have the response as JSON use soapResponse.toJSON();
// or soapResponse.toString() to get XML string
// or soapResponse.toXML() to get XML DOM
},
error: function (SOAPResponse) {
// show error
}
});
Has anyone tried this? https://github.com/doedje/jquery.soap
Seems very easy to implement.
Example:
$.soap({
url: 'http://my.server.com/soapservices/',
method: 'helloWorld',
data: {
name: 'Remy Blom',
msg: 'Hi!'
},
success: function (soapResponse) {
// do stuff with soapResponse
// if you want to have the response as JSON use soapResponse.toJSON();
// or soapResponse.toString() to get XML string
// or soapResponse.toXML() to get XML DOM
},
error: function (SOAPResponse) {
// show error
}
});
will result in
<soap:Envelope
xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:Body>
<helloWorld>
<name>Remy Blom</name>
<msg>Hi!</msg>
</helloWorld>
</soap:Body>
</soap:Envelope>
Thomas:
JSON is preferred for front end use because we have easy lookups. Therefore you have no XML to deal with. SOAP is a pain without using a library because of this. Somebody mentioned SOAPClient, which is a good library, we started with it for our project. However it had some limitations and we had to rewrite large chunks of it. It's been released as SOAPjs and supports passing complex objects to the server, and includes some sample proxy code to consume services from other domains.

This may not meet all your requirements but it is a start at actually answering your question. (I switched XMLHttpRequest() for ActiveXObject("MSXML2.XMLHTTP")).
Some great examples (and a ready-made JavaScript SOAP client!) here:
http://plugins.jquery.com/soap/
Check the readme, and beware the same-origin browser restriction.
The question is 'What is the simplest SOAP example using Javascript?'
This answer is of an example in the Node.js environment, rather than a browser. (Let's name the script soap-node.js) And we will use the public SOAP web service from Europe PMC as an example to get the reference list of an article.
const XMLHttpRequest = require("xmlhttprequest").XMLHttpRequest;
const DOMParser = require('xmldom').DOMParser;
function parseXml(text) {
let parser = new DOMParser();
let xmlDoc = parser.parseFromString(text, "text/xml");
Array.from(xmlDoc.getElementsByTagName("reference")).forEach(function (item) {
console.log('Title: ', item.childNodes[3].childNodes[0].nodeValue);
});
}
function soapRequest(url, payload) {
let xmlhttp = new XMLHttpRequest();
xmlhttp.open('POST', url, true);
// build SOAP request
xmlhttp.onreadystatechange = function () {
if (xmlhttp.readyState == 4) {
if (xmlhttp.status == 200) {
parseXml(xmlhttp.responseText);
}
}
}
// Send the POST request
xmlhttp.setRequestHeader('Content-Type', 'text/xml');
xmlhttp.send(payload);
}
soapRequest('https://www.ebi.ac.uk/europepmc/webservices/soap',
`<?xml version="1.0" encoding="UTF-8"?>
<S:Envelope xmlns:S="http://schemas.xmlsoap.org/soap/envelope/">
<S:Header />
<S:Body>
<ns4:getReferences xmlns:ns4="http://webservice.cdb.ebi.ac.uk/"
xmlns:ns2="http://www.scholix.org"
xmlns:ns3="https://www.europepmc.org/data">
<id>C7886</id>
<source>CTX</source>
<offSet>0</offSet>
<pageSize>25</pageSize>
<email>ukpmc-phase3-wp2b---do-not-reply#europepmc.org</email>
</ns4:getReferences>
</S:Body>
</S:Envelope>`);
Before running the code, you need to install two packages:
npm install xmlhttprequest
npm install xmldom
Now you can run the code:
node soap-node.js
And you'll see the output as below:
Title: Perspective: Sustaining the big-data ecosystem.
Title: Making proteomics data accessible and reusable: current state of proteomics databases and repositories.
Title: ProteomeXchange provides globally coordinated proteomics data submission and dissemination.
Title: Toward effective software solutions for big biology.
Title: The NIH Big Data to Knowledge (BD2K) initiative.
Title: Database resources of the National Center for Biotechnology Information.
Title: Europe PMC: a full-text literature database for the life sciences and platform for innovation.
Title: Bio-ontologies-fast and furious.
Title: BioPortal: ontologies and integrated data resources at the click of a mouse.
Title: PubMed related articles: a probabilistic topic-based model for content similarity.
Title: High-Impact Articles-Citations, Downloads, and Altmetric Score.
Simplest example would consist of:
Getting user input.
Composing XML SOAP message similar to this
<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>
<GetInfoByZIP xmlns="http://www.webserviceX.NET">
<USZip>string</USZip>
</GetInfoByZIP>
</soap:Body>
</soap:Envelope>
POSTing message to webservice url using XHR
Parsing webservice's XML SOAP response similar to this
<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>
<GetInfoByZIPResponse xmlns="http://www.webserviceX.NET">
<GetInfoByZIPResult>
<NewDataSet xmlns="">
<Table>
<CITY>...</CITY>
<STATE>...</STATE>
<ZIP>...</ZIP>
<AREA_CODE>...</AREA_CODE>
<TIME_ZONE>...</TIME_ZONE>
</Table>
</NewDataSet>
</GetInfoByZIPResult>
</GetInfoByZIPResponse>
</soap:Body>
</soap:Envelope>
Presenting results to user.
But it's a lot of hassle without external JavaScript libraries.
function SoapQuery(){
var namespace = "http://tempuri.org/";
var site = "http://server.com/Service.asmx";
var xmlhttp = new ActiveXObject("Msxml2.ServerXMLHTTP.6.0");
xmlhttp.setOption(2, 13056 ); /* if use standard proxy */
var args,fname = arguments.callee.caller.toString().match(/ ([^\(]+)/)[1]; /*Имя вызвавшей ф-ции*/
try { args = arguments.callee.caller.arguments.callee.toString().match(/\(([^\)]+)/)[1].split(",");
} catch (e) { args = Array();};
xmlhttp.open('POST',site,true);
var i, ret = "", q = '<?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><'+fname+ ' xmlns="'+namespace+'">';
for (i=0;i<args.length;i++) q += "<" + args[i] + ">" + arguments.callee.caller.arguments[i] + "</" + args[i] + ">";
q += '</'+fname+'></soap:Body></soap:Envelope>';
// Send the POST request
xmlhttp.setRequestHeader("MessageType","CALL");
xmlhttp.setRequestHeader("SOAPAction",namespace + fname);
xmlhttp.setRequestHeader('Content-Type', 'text/xml');
//WScript.Echo("Запрос XML:" + q);
xmlhttp.send(q);
if (xmlhttp.waitForResponse(5000)) ret = xmlhttp.responseText;
return ret;
};
function GetForm(prefix,post_vars){return SoapQuery();};
function SendOrder2(guid,order,fio,phone,mail){return SoapQuery();};
function SendOrder(guid,post_vars){return SoapQuery();};
Angularjs $http wrap base on XMLHttpRequest. As long as at the header content set following code will do.
"Content-Type": "text/xml; charset=utf-8"
For example:
function callSoap(){
var url = "http://www.webservicex.com/stockquote.asmx";
var soapXml = "<soapenv:Envelope xmlns:soapenv=\"http://schemas.xmlsoap.org/soap/envelope/\" xmlns:web=\"http://www.webserviceX.NET/\"> "+
"<soapenv:Header/> "+
"<soapenv:Body> "+
"<web:GetQuote> "+
"<web:symbol></web:symbol> "+
"</web:GetQuote> "+
"</soapenv:Body> "+
"</soapenv:Envelope> ";
return $http({
url: url,
method: "POST",
data: soapXml,
headers: {
"Content-Type": "text/xml; charset=utf-8"
}
})
.then(callSoapComplete)
.catch(function(message){
return message;
});
function callSoapComplete(data, status, headers, config) {
// Convert to JSON Ojbect from xml
// var x2js = new X2JS();
// var str2json = x2js.xml_str2json(data.data);
// return str2json;
return data.data;
}
}

I have a server running OTRS 5 and I would like to retrieve a list in XML format. I'm running a JavaScript code that should display the list, but instead I get an error.
My local server is https://labcentos3/otrs/mds.pl?Action=ServiceList.
I think its a Perl script that runs on the server side and then displays a list in XML format.
This is what I get if I browse the local link: it gives me the list I want
I wrote HTML and JavaScript to try to do the same for working with the retrieved data later, but I can't get past an error.
HTML

var user = "bla bla bla";
var pass = "bla bla bla"
var getXMLFile = function(path, callback) {
var request = new XMLHttpRequest();
request.open("POST", path);
request.setRequestHeader("Content-Type", "text/plain");
//request.setRequestHeader("Content-Type", "application/x-www-form-urlencoded");
request.setRequestHeader('Authorization', 'Basic ' + btoa(user + ":" + pass));
request.onreadystatechange = function() {
if(request.readyState === 4 && request.status === 200) {
callback(request.responseXML);
}
};
request.send();
};
getXMLFile("https://labcentos3/otrs/mds.pl?Action=ServiceList", function(xml) {
console.log(xml);
});
The error I get in the Chrome console is this:
XMLHttpRequest cannot load https://labcentos3/otrs/mds.pl?Action=ServiceList. The request was redirected to 'https://labcentos3/otrs/index.pl', which is disallowed for cross-origin requests that require preflight.
I have a function in my Apache Cordova application to create a new list item inside a sharepoint list, and I was wondering if it was possible to add an image to this new item, this would come as an 'attachment' in the sharepoint list. My function to add a new item looks like this:
function CreateItem(Title, Description) {
var soapEnv =
"<soapenv:Envelope xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" " +
"xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" " +

"<soapenv:Body>" +
"<UpdateListItems xmlns=\"http://schemas.microsoft.com/sharepoint/soap/\">" +

"<updates>" +
"<Batch OnError=\"Continue\">" +
"<Method ID=\"1\" Cmd=\"New\">" +
"<Field Name=\"ID\">New</Field>" +
"<Field Name=\"Title\">" + Title + "</Field>" +
"<Field Name=\"Description\">" + Description + "</Field>" +
"</Method>" +
"</Batch>" +
"</updates>" +
"</UpdateListItems>" +
"</soapenv:Body>" +
"</soapenv:Envelope>";
$.ajax({
url: "URL",
type: "POST",
dataType: "xml",
data: soapEnv,
beforeSend: function (xhr) {
xhr.setRequestHeader("SOAPAction",
"http://schemas.microsoft.com/sharepoint/soap/UpdateListItems");
},
complete: processCreateResultSuccess,
contentType: "text/xml; charset=\"utf-8\"",
error: processCreateResultError
});
}
The image is taken with the Cordova app and has the ID "image". Any thoughts?
SharePoint: AddAttachment SOAP Web Service
Yes, you can use SharePoint SOAP web services to upload an image attachment to a list. However, there are some limitations.
My demo below uses the AddAttachment action of the Lists web service. The required parameters are listed and can be modified for your own environment. The demo simply adds a text file attachment, but it works with images and other file types too. Also works with SP 2007-2013.
The limitation is that files must be encoded as base-64 for transfer within the SOAP envelope. On the client side, base-64 file encoding is not a trivial task. I've done it using the FileReader object, but that is only available in modern browsers (IE10). There might be other options with mobile devices, but I've not researched it. Alternatively, you might look at the newer REST API.
<html>
<body>
<script type='text/javascript'>
function addAttachment( ) {
var webUrl = '', // base url when list in sub site
listName = 'CustomList', // list name or guid
listItemID = '1', // list item id
fileName = 'HelloWorld.txt', // file name
attachment = 'SGVsbG8gV29ybGQ=', // base-64 encode file data "Hello Word!"
xhr, soap;
soap = (
'<?xml version="1.0" encoding="utf-8"?>'+

);
xhr = new XMLHttpRequest();
xhr.open( 'POST', webUrl + '/_vti_bin/Lists.asmx', true );
xhr.setRequestHeader('Content-Type', 'text/xml; charset=utf-8');
xhr.setRequestHeader('SOAPAction', 'http://schemas.microsoft.com/sharepoint/soap/AddAttachment');
xhr.onreadystatechange = function() {
if (xhr.readyState != 4) return;

I am trying to call a (.asmx) soap web service that require basic authentication using jQuery (or anything that would work).
And how to pass parameters to the (.asmx) soap web service
I've not been able to come up with any answers on Google. Is it possible?
OK, Finally I was able to resolve this issue :)
I was searching in the wrong direction, I was looking how to open the URL secured by basic authentication using $.Ajax, where I should search for consuming SOAP service from JavaScript using XMLHttpRequest()
the following is the answer to my question:
var symbol = "MSFT";
var xmlhttp = new XMLHttpRequest();
//xmlhttp.open("POST", "http://www.webservicex.net/stockquote.asmx?op=GetQuote", true);
// if you use username and password to secure your URL
xmlhttp.open("POST", "http://www.webservicex.net/stockquote.asmx?op=GetQuote", true, 'username', 'password');
xmlhttp.onreadystatechange = function() {
if (xmlhttp.readyState == 4) {
console.log(xmlhttp.responseText);
}
}
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" ' +

'<symbol>' + symbol + '</symbol> ' +
'</GetQuote> ' +
'</soap:Body> ' +
'</soap:Envelope>';
xmlhttp.send(xml);
You need to use jquery ajax for that.
var uri="http://asmx_file_path/asmx_service_file_name/method_name_in_asmx_file"
//ex: var uri = "http://mysite.test.com/services/data/mobile.asmx?method=login&username=" + uname+ "&password=" + pwd;
$.ajax({
type: "GET",
url: uri,
success: function (msg) {
jasondata = eval('(' + msg + ')');
},
});
You also need to add service reference for that asmx file.
<asp:ScriptManagerProxy ID="ScriptManagerProxy1" runat="server">
<Services>
<asp:ServiceReference Path="~/services/data/mobile.asmx" />
</Services>
</asp:ScriptManagerProxy>
You can have a look at this tutorial.

So I have this HTML file that tests the user's screen resolution, and plugins installed using Javascript. So when the user accesses the page it sees: (e.g.) Your current screen resolution is 1024x768 and you have the following plugins installed: Plug-in No.2- Java Deployment Toolkit 7.0.10.8 [Location: npdeployJava1.dll], Plug-in No.3- Java(TM) Platform SE 7 U1 [Location: npjp2.dll], Plug-in No.4- Microsoft Office 2003 [Location: NPOFFICE.DLL]... I also need to save this information in a file on the server. All users are having firefox or chrome. How do I do this using AJAX?
<html>
<body>
<script language="JavaScript1.2">
document.write("Your current resolution is "+screen.width+"*"+screen.height+"")

Thanks
Without jQuery (raw JavaScript):
var data = "...";// this is your data that you want to pass to the server (could be json)
//next you would initiate a XMLHTTPRequest as following (could be more advanced):
var url = "get_data.php";//your url to the server side file that will receive the data.
var http = new XMLHttpRequest();
http.open("POST", url, true);
//Send the proper header information along with the request
http.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
http.setRequestHeader("Content-length", data.length);
http.setRequestHeader("Connection", "close");
http.onreadystatechange = function() {//Call a function when the state changes.
if(http.readyState == 4 && http.status == 200) {
alert(http.responseText);//check if the data was received successfully.
}
}
http.send(data);
Using jQuery:
$.ajax({
type: 'POST',
url: url,//url of receiver file on server
data: data, //your data
success: success, //callback when ajax request finishes
dataType: dataType //text/json...
});
I hope this helps :)

Do you know jQuery? It will be much easier with jQuery.
var data = "";
for (var i=0; i < num_of_plugins; i++) {
var list_number=i+1;
document.write("<font color=red>Plug-in No." + list_number + "- </font>"+navigator.plugins[i].name+" <br>[Location: " + navigator.plugins[i].filename + "]<p>");
data += "<font color=red>Plug-in No." + list_number + "- </font>"+navigator.plugins[i].name+" <br>[Location: " + navigator.plugins[i].filename + "]<p>";
}
$.post('savedata.php', {data=data}, function(){//Save complete});
Then in savedata.php you can write something like the following:
$data = $_POST['data'];
$f = fopen('file', 'w+');
fwrite(f, $data);
fclose($f);
Do a request from javascript to a page which runs server side code.
Send post request with ajax http://www.javascriptkit.com/dhtmltutors/ajaxgetpost.shtml to for example an apsx page. From aspx you could save it to a text file or database.
I am calling a web service which is located on another host.
It is working fine in IE but not in FF,Opera etc..
Here is my code :
if(xmlHttpReq.readyState == 0){
xmlHttpReq.open('POST', strURL, true);
xmlHttpReq.setRequestHeader('Content-Type', 'application/x-www-form-urlencoded');
xmlHttpReq.onreadystatechange = function() {
if (xmlHttpReq.readyState == 4 && xmlHttpReq.status == 200) {
var resultString = xmlHttpReq.responseXML;
document.getElementById('webserviceresponsetext').value = resultString.text;
}
}
xmlHttpReq.send(packet);
}
}
var packet = '<?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>'+
'<authenticate xmlns="http://interfaces.service.webservices.webs.eic.com">" '+
'<ParameterName>abc</ParameterName>'+
'<ParameterName>1234</ParameterName>'+
'</authenticate></soap:Body>'+
'</soap:Envelope>';
This method just calls authenticate method and returns true/false if user abc is valid user or not.1234 is password for abc user.
Please help...
Thanks in advance...
I am getting this error in FF:
XML Parsing Error: no element found Location: moz-nullprincipal:{cb5142f9-33a8-44ca-bc9d-60305ef7cea8} Line Number 1, Column 1:
If you want ajax to reliably work across browsers, I'd recommend using jQuery.
It'll abstract away the complexity of dealing with the XmlHttpReq directly, give you a much cleaner syntax and work across all major browsers.
Have a look at jQuery's ajax API for a start.
Your code could look similar to this:
$.ajax({
url: "test.html",
context: document.body,
success: function(){
$(this).addClass("done");
}
});
