regarding Login User and Owner of record

hi i am using below code to check login user and owner f record is same or not 

function loginUser() {
var setUservalue = Xrm.Page.context.getUserName();
alert(setUservalue + typeof (setUservalue));
var value = Xrm.Page.getAttribute("ownerid").getValue();
var Name = value[0].name;
console.log(value);
alert(Name + typeof (Name));
if (setUservalue === value) {
alert("success");
}
