如果将数字粘贴到第一个框中，如何将数字分发到其他框？

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

在 JSfiddle

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();
  }
 }
});

.passInput {text-align: center;}

<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>
</form>

推荐答案

要获取剪贴板数据文本，请使用 ev.originalEvent.clipboardData.getData（'text'），

比确保剪裁长度正好是6个字符长并且都是数字。

通过拆分字符串为每个输入分配新值，并聚焦最后一个输入：

To get the clipboard data text use ev.originalEvent.clipboardData.getData('text'),
than make sure the trimmed length is exactly 6 characters long and all are digits.
Assign to each input it's new value by splitting the string, and focus the last input:

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

$inp.on({
  paste(ev) {
    const pasteStr = ev.originalEvent.clipboardData.getData('text').trim();
    if (!/\d{6}/.test(pasteStr)) return ev.preventDefault(); // pass invalid. Exit here
    const s = pasteStr.split('');
    $inp.val(i => s[i]).eq(5).focus(); 
  },
  input(ev) {
    if (this.value) $inp.eq($inp.index(this) + 1).focus();
  },
  keydown(ev) {
    const i = $inp.index(this);
    if (ev.which === 8 && !this.value && i) $inp.eq(i - 1).focus();
  }
});

.passInput {
  text-align: center;
}

Copy and paste into any field: 456123<br>
Than try with some invalid string: aA123B

<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>
</form>
