Use errorPlacement option

errorPlacement (default: Places the error label after the invalid element) Type: Function() Customize placement of created error labels. First argument: The created error label as a jQuery object. Second argument: The invalid element as a jQuery object.

    errorPlacement: function(error,element){ 
                        //error.insertAfter(element); 
                        //use error.html() as content in your popup div or simply
                        alert(error.html());             
                     }
