Ajax json_encode error: "Uncaught SyntaxError: Unexpected token :" when returning array with keys

Chrome console shows error when I send json_encode from php with defined keys, but works when I do not define keys:

"Uncaught SyntaxError: Unexpected token :"

This PHP ajax_return_array.php code works:

 $array = array("a","b","c","d");
 echo json_encode( $array );

This PHP jax_return_array.php code fails:

 $array = array(1=>"a",2=>"b",3=>"c",4=>"d");
 echo json_encode( $array );

jquery ajax:

$.ajax({
    type: "POST",
    url: "ajax_return_array.php",
    success: function(result) {
        if(result) {
            resultObj = eval (result);
            alert( resultObj );
        } else {
            alert("error");
        }
    }
});
