You need to make a soap request in a js file.
In your js file you should have something like this:
function sendSOAPRequest(webServiceMethod, params, callbackMethod, isAsynchronous, callContext)
{
//Get the token from local storage
var token = window.localStorage.getItem("token");
//Get the soap envelope with given parameters
var soapEnvelope = getEnvelopeFromParam(webServiceMethod, params);
//Send the soap request
$.ajax({
url: "https://www.zzz.com/yyy/soap",
type: "POST",
dataType: "xml",
data: soapEnvelope,
context: callContext,
complete: callbackMethod,
async: isAsynchronous,
timeout: 60000,
contentType: "text/xml; charset=\"utf-8\"",
beforeSend: function (xhr) {
xhr.setRequestHeader('SOAPAction', 'http://zzz.com/yyy/uuu/Iooo/' + webServiceMethod);
xhr.setRequestHeader('Authorization', token);
}
});
}
function getEnvelopeFromParam(webServiceMethod, parameters)
{
var soapEnvelope = '<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/"><s:Body><' + webServiceMethod + ' xmlns="http://zzz.com/yyy/uuu">';
$.each(parameters, function(key, value) {
if(value)
{
soapEnvelope += '<' + key + '>' + value + '</' + key + '>';
}
else
{
//Send a null value
soapEnvelope += '<' + key + ' i:nil="true" xmlns:i="http://www.w3.org/2001/XMLSchema-instance"/>';
}
});
soapEnvelope += '</' + webServiceMethod + '></s:Body></s:Envelope>';
return soapEnvelope;
}
this is a method to call webservice. You have the specify the right adresses corresponding to your server.
Now include this js file in your html
<script type="text/javascript" src="myFile.js"></script>
Now you have to call your js function from your html page (for exemple)
sendSOAPRequest("myfunction", params, endFunction, true, this);
And you have to define the endFunction
function endFunction(xmlHttpRequest, status)
{
//Work with xmlHttpRequest and check status
}
