Answer 1

verwenden Sie einfach jede Funktion über die Ein- und prüfen, ob ist impty:

$(function() { 
 
    $('#submit').on('click', function() { 
 
     $("input").each(function() { 
 
      if ($(this).val() == "") { 
 
       $(this).css('border-color', 'red'); 
 
      } 
 
      else $(this).css('border-color', 'green'); 
 
     }); 
 
     return false; 
 
    }); 
 
});

input { 
 
    border: none; 
 
    padding: 4px 0; 
 
    background: 0 0; 
 
    text-align: left; 
 
    outline: none; 
 
    display: block; 
 
    width: 100%; 
 
    border-bottom: 1px solid #ccc 
 
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> 
 
<input type='text' id='title' placeholder='Add title'> 
 
<input type='text' id='location' placeholder='Add location'> 
 
<input type='text' id='description' placeholder='Add description'> 
 
<input type='time' id='time'> 
 
<button id='submit'>submit</button>
