MSCRM 2011 - Disable fields based on Lookup Change - Retrieve Lookup Values using Javascript

Right now i am going to brief about retrieving value from MSCRM lookup field and disabling the other fields based on Lookup change.

Scenario :

I have a lookup, in which i want to disable other field whenever the lookup value is selected as "Country". Here the sample script.

//Code Starts
var lookupItem = new Array;

if (Xrm.Page.getAttribute("lookupfieldid").getValue())
{
    lookupItem = Xrm.Page.getAttribute("lookupfieldid ").getValue();

    if (lookupItem[0] != null)
    {
        if (lookupItem[0].name == "Country")
        {
            Xrm.Page.getControl("fieldname").setDisabled(true);
        }
        else
        {
            Xrm.Page.getControl("fieldname").setDisabled(false);
        }
    }

}
//Code end.

Add the above code on the Lookup field on change event.
