Migration to CRM 2011/13/15 and Converting CRM 4.0 JavaScript

I’ve seen a lot of CRM 4.0 JavaScript over the past years. A lot of us used unsupported customization to create a better user experience that fit the needs of our clients but sometimes these customization are unsupported… but do the job! (At one time  J ). The problem comes when we need to migrate the code to a newer version! 

When using the solution to detect errors on the code we usually came across the following:
·        .text
·        .selectSingleNode
·        ActiveXObject
·        crmForm.all
·        crmFormSubmit

So here are some examples how to convert:

CRM 4.0
CRM 2011/13/15
var id = crmFormSubmit.crmFormSubmitId.value;

var id = Xrm.Page.data.entity.getId();
var postalcode = crmForm.all.address1_postalcode.DataValue;

var postalcode = Xrm.Page.getAttribute("address1_postalcode").getValue();


var accountValue = accountLookup.DefaultValue[0].data = accountLookup.getValue()[0].data;
var accountValue = Xrm.Page.getAttribute("sourcefield").getValue();
 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);
var xmlHttpRequest = new XMLHttpRequest();
    xmlHttpRequest.open('POST', getServerUrl() + '/XRMServices/2011/Organization.svc/web', false);
    xmlHttpRequest.setRequestHeader('Accept', 'application/xml, text/xml, */*');
    xmlHttpRequest.setRequestHeader('Content-Type', 'text/xml; charset=utf-8');
    xmlHttpRequest.setRequestHeader('SOAPAction', 'http://schemas.microsoft.com/xrm/2011/Contracts/Services/IOrganizationService/Retrieve');
// IE 8 and below
var node = resultXml.selectSingleNode("//Entity/");
  // IE 9/10, Chrome, Firefox & Safari
 parser = new DOMParser();
 var node = parser.parseFromString(resultXml, "text/xml");
 node = node.getElementsByTagName("Entity/ ")[0];

This solution is useful to convert the code automatically but be careful some of the code is not converted properly.
