There’s a box with six entries. If the desired number is directly pasted into the boxes..

123456

How do I distribute the numbers to the other boxes when they are pasted into the first box?

on JSfiddle

Javascript:

var $inp = $(".passInput");

$inp.on({
 input: function(ev) {
  if(this.value) {
    $inp.eq($inp.index(this) + 1).focus();
  }
 },
 keydown: function(ev) {
  var i = $inp.index(this);
  if(ev.which===8 && !this.value && i) {
    $inp.eq(i - 1).focus();
  }
 }
});

HTML:

<form action="" role="form" method="post" id="passForm">
  <input type="text" class="passInput" name="pass[]" maxLength="1" size="1" autocomplete="off" min="0" max="9" required pattern="\d{1}" autofocus>
  <input type="text" class="passInput" name="pass[]" maxLength="1" size="1" autocomplete="off" min="0" max="9" required pattern="\d{1}">
  <input type="text" class="passInput" name="pass[]" maxLength="1" size="1" autocomplete="off" min="0" max="9" required pattern="\d{1}">
  <input type="text" class="passInput" name="pass[]" maxLength="1" size="1" autocomplete="off" min="0" max="9" required pattern="\d{1}">
  <input type="text" class="passInput" name="pass[]" maxLength="1" size="1" autocomplete="off" min="0" max="9" required pattern="\d{1}">
  <input type="text" class="passInput" name="pass[]" maxLength="1" size="1" autocomplete="off" min="0" max="9" pattern="\d{1}">
  <button type="submit" class="btn btn-lg btn-primary">SUBMIT</button>
