This should work:

   Click

JQuery

$(function(){

    $('button').click(function(){

    var len = $('input').length,i,k;
    $('input').css({'border':'solid 1px #888'})

    for(i=0; i < len; i++){
      var v = $('input:eq('+ i +')').val();
      for( k=0; k < i; k++ ){
        var s = $('input:eq('+ k +')').val();
        if( s == v ){
          $('input:eq('+ i +')').css({'border':'solid 1px #F00'})
          $('input:eq('+ k +')').css({'border':'solid 1px #F00'})
          return false;
        }
       }
     }
  })

})
