```
$(function(){
    $.ajax({
        url: 'http://xxx/',
        type: 'GET',
        crossDomain:true,
        cache:true,
        dataType:"script",
        success:function(data,textStatus,jqXHR){

            alert(data);
        }
    }); 
});

```

actually server is returning json object and in my firebug it is showing 
SyntaxError: invalid label
