jquery - Stop $.ajax on beforeSend

Question

I have this jQuery ajax call:

$.ajax({
    url : 'my_action',
    dataType: 'script',
    beforeSend : function(){
        if(1 == 1) //just an example
        {
            return false
        }
    },
    complete: function(){
        console.log('DONE');
    }
});

I want to stop the ajax call under the beforeSend if the condition returns true but return false does not stop the ajax call.

How can I stop the ajax call on the beforeSend?

======= UPDATE =========

return false works as well.

$.ajax({
    url : 'my_action',
    dataType: 'script',
    beforeSend : function(xhr, opts){
        if(1 == 1) //just an example
        {
            xhr.abort();
        }
    },
    complete: function(){
        console.log('DONE');
    }
});
