MSCRM: testing a User's Role (CRM 4.0 only)

Code required to test whether the logged in user to Microsoft CRM has a particular role:

function currentUserHasRole(roleName)
{
//get Current User Roles
var oXml = GetCurrentUserRoles();

if(oXml != null)
{
//get list of role names
var roles = oXml.selectNodes("//BusinessEntity/q1:name");

if(roles != null)
{
for( i = 0; i < roles.length; i++)
{
if(roles[i].text == roleName)
{
//return true if user has this role
return true;
}
}
}

}
//not found, return false
return false;

}

function GetCurrentUserRoles()
{
var 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\">" +

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);
xmlHttpRequest.send(xml);

var resultXml = xmlHttpRequest.responseXML;
return(resultXml);

}



The code need to be placed at the top of any Form Event where you want to use the function. the function can then simply be called as follows:

if(currentUserHasRole(‘Salesperson')){
//do this stuff
}else{
//do other stuff
}



We hope this helps anyone getting to grips with java script coding in MSCRM 4.0!

Please post any thoughts or improvements that you have to this.
