        var depaterment = document.getElementById('depaterment') ;
        var  select_v=parseInt(depaterment.options[depaterment.selectedIndex].value);
       // alert(select_v);
        switch(select_v){
        case 111:
             document.getElementById('txt').value='111'
             document.getElementById('mem').value='111部门'
             break;
                 case 222:
             document.getElementById('txt').value='222'
             document.getElementById('mem').value='222部门'
             break;
                 case 333:
             document.getElementById('txt').value='333'
             document.getElementById('mem').value='333部门'
             break;
        }
}
