How to call/launch/execute workflow and wait until its execution to make some action with JavaScript in Microsoft Dynamics CRM

from here: http://a33ik.blogspot.com/2009/09/how-to-calllaunchexecute-workflow-and.html

Author of code for workflow executing is Jian Wang. I wrote a code that waits for the workflow to be completed.

So the code:

ExecuteWorkflow = function(entityId, workflowId)

{

   var xml = "" +

   "\"1.0\" encoding=\"utf-8\"?>" +

   "\"http://schemas.xmlsoap.org/soap/envelope/\" xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\">" +

   GenerateAuthenticationHeader() +

   "  " +

   "    \"http://schemas.microsoft.com/crm/2007/WebServices\">" +

   "      \"ExecuteWorkflowRequest\">" +

   "        " + entityId + "" +

   "        " + workflowId + "" +

   "      " +

   "    " +

   "  " +

   "" +

   "";



   var xmlHttpRequest = new ActiveXObject("Msxml2.XMLHTTP");

   xmlHttpRequest.Open("POST", "/mscrmservices/2007/CrmService.asmx", false);

   xmlHttpRequest.setRequestHeader("SOAPAction","http://schemas.microsoft.com/crm/2007/WebServices/Execute");

   xmlHttpRequest.setRequestHeader("Content-Type", "text/xml; charset=utf-8");

   xmlHttpRequest.setRequestHeader("Content-Length", xml.length);

   xmlHttpRequest.send(xml);

   var resultXml = xmlHttpRequest.responseXML;

   return(resultXml.selectSingleNode('//soap:Envelope/soap:Body/ExecuteResponse/Response/Id').nodeTypedValue);

}



WaitWorkflowExecution = function(workflowId)

{

   var xml = ""+

   "+

   " xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance'"+

   " xmlns:xsd='http://www.w3.org/2001/XMLSchema'>"+

   GenerateAuthenticationHeader() +

   ""+

   ""+

   "asyncoperation"+

   ""+workflowId+""+

   ""+

   ""+

   "statuscode"+

   ""+

   ""+

   ""+

   ""+

   "";



   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);

   var resultXml = xHReq.responseXML;



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

   if (errorCount != 0)

   {

       setTimeout("WaitWorkflowExecution('" + workflowId + "');", 1000);

      

   }

   else

   {

       var executionstatus = resultXml.selectSingleNode("//soap:Envelope/soap:Body/RetrieveResponse/RetrieveResult/q1:statuscode").nodeTypedValue;

  



       if (executionstatus == 30)//Workflow completed

       {

           alert("Workflow Completed!");

       }

       else

       {

           setTimeout("WaitWorkflowExecution('" + workflowId + "');", 1000);

       }

   }

}



var theWorkflowId = "6eb47269-4139-40b3-a96d-255ef2d78e6a"; //change to your workflow Id

var workflowInstanceId = ExecuteWorkflow(crmForm.ObjectId, theWorkflowId);



WaitWorkflowExecution(workflowInstanceId);
