Пример SOAP-запроса

Задача: Заполнить атрибут формы значением атрибута связанной сущности.

Решение: написан код на JScript

var oAttribute = crmForm.all.campaignid;
if (oAttribute.DataValue != null && oAttribute.DataValue[0] != null)
{

sEntityName = 'campaign';
GUID = oAttribute.DataValue[0].id;
sAttributeName = 'new_sourceid';

var authenticationHeader = GenerateAuthenticationHeader();

// Prepare the SOAP message.
var xml = "";
xml = 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'>"+
authenticationHeader+
"<soap:Body>"+
"<Retrieve xmlns='http://schemas.microsoft.com/crm/2007/WebServices'>"+
"<entityName>"+sEntityName+"</entityName>"+
"<id>"+GUID+"</id>"+
"<columnSet xmlns:q1='http://schemas.microsoft.com/crm/2006/Query' xsi:type='q1:ColumnSet'>"+
"<q1:Attributes>"+
"<q1:Attribute>"+sAttributeName+"</q1:Attribute>"+
"</q1:Attributes>"+
"</columnSet>"+
"</Retrieve>"+
"</soap:Body>"+
"</soap:Envelope>";

// Prepare the xmlHttpObject and send the request.
var xHReq = new ActiveXObject("Msxml2.XMLHTTP");
xHReq.Open("POST", "/mscrmservices/2007/CrmService.asmx", false);
xHReq.setRequestHeader("SOAPAction","http://schemas.microsoft.com/crm/2007/WebServices/Retrieve");
xHReq.setRequestHeader("Content-Type", "text/xml; charset=utf-8");
xHReq.setRequestHeader("Content-Length", xml.length);
xHReq.send(xml);
// Capture the result.
var resultXml = xHReq.responseXML;

// Check for errors.
var errorCount = resultXml.selectNodes('//error').length;

if (errorCount == 0)
{
if (resultXml.selectSingleNode("//q1:" + sAttributeName) != null)
{
var lookupData = new Array();
var lookupItem = new Object();
var id;
lookupItem.id = resultXml.selectSingleNode("//q1:" + sAttributeName).nodeTypedValue;
lookupItem.typename = 'new_source';
var customername = resultXml.selectSingleNode("//q1:" + sAttributeName).getAttribute("name");

lookupItem.name = customername;
lookupData[0] = lookupItem;
crmForm.all.new_sourceid.DataValue = lookupData;
}
}
}
