Getting values from a lookup control

We recently needed to capture both the GUID and the text value from a CRM lookup control. I found some quick code to do this on the following newsgroup:

var lookupItem = new Array;

lookupItem = crmForm.all.primarycontactid.DataValue;

if (lookupItem[0] != null)
{
// The text value of the lookup.
alert(lookupItem[0].name);

// The GUID of the lookup.
alert(lookupItem[0].id);
}
