CRM 2011 – Setting a user lookup with the logged in user with Javascript

Sometimes you need to log the current user in a User Lookup.

Xrm.Page.context.getUserId()

if you wanted to set a user lookup field you would need to do this

var setUservalue = new Array();
 setUservalue[0] = new Object();
 setUservalue[0].id = Xrm.Page.context.getUserId();
 setUservalue[0].entityType = 'systemuser';
//setUservalue[0].name = retrievedUser.FullName;

Xrm.Page.getAttribute("meta_aurarrangedby").setValue(setUservalue)

meta_aurarrangedby is a user lookup field

This will set the correct guid but the user name will be blank until the page is reloaded if you want to add the user name then you need to retrieve the user name using the guid the example code below will do this using an OData query but you will have to add the json2.js file to the entity so it can be called from your javascript.

function Getinfo() {
 var context;
 var serverUrl;
 var UserID;
 var ODataPath;
 context = Xrm.Page.context;
 serverUrl = context.getServerUrl();
 UserID = context.getUserId();
 ODataPath = serverUrl + "/XRMServices/2011/OrganizationData.svc";
 var retrieveUserReq = new XMLHttpRequest();
 retrieveUserReq.open("GET", ODataPath + "/SystemUserSet(guid'" + UserID + "')", true);
 retrieveUserReq.setRequestHeader("Accept", "application/json");
 retrieveUserReq.setRequestHeader("Content-Type", "application/json; charset=utf-8");
 retrieveUserReq.onreadystatechange = function () {
 retrieveUserReqCallBack(this);
 };
 retrieveUserReq.send();

}

function retrieveUserReqCallBack(retrieveUserReq) {
if (retrieveUserReq.readyState == 4 /* complete */) {

if (retrieveUserReq.status == 200) {
 var retrievedUser = this.parent.JSON.parse(retrieveUserReq.responseText).d;
 if (retrievedUser.FullName != null)

var setUservalue = new Array();
 setUservalue[0] = new Object();
 setUservalue[0].id = Xrm.Page.context.getUserId();
 setUservalue[0].entityType = 'systemuser';
 setUservalue[0].name = retrievedUser.FullName;

Xrm.Page.getAttribute("meta_aurarrangedby").setValue(setUservalue)
 }

else {

 }
 }
}
