并且前6个文本框仅允许单个数字，接下来的6个文本框仅允许两个数字。

和所有需要的文本框

Answer 1

有一个名为maxlength的选项。您需要使用它来限制数字。

.textbox1 {
  width: 20px;
  margin-left: 50px;
}
.textbox2 {
  width: 20px;
  margin-left: 10px;
}
.textbox3 {
  width: 20px;
  margin-left: 10px;
}
.textbox4 {
  width: 20px;
  margin-left: 10px;
}
.textbox5 {
  width: 20px;
  margin-left: 10px;
}
.textbox6 {
  width: 20px;
  margin-left: 10px;
}
.textbox7 {
  width: 30px;
  margin-left: 10px;
}
.textbox8 {
  width: 50px;
  margin-left: 100px;
}
.textbox9 {
  width: 50px;
  margin-left: 10px;
}
.textbox10 {
  width: 50px;
  margin-left: 10px;
}
.textbox11 {
  width: 50px;
  margin-left: 10px;
}
.textbox12 {
  width: 50px;
  margin-left: 10px;
}
.txtfkey {
  width: 250px;
}

<form id="form1">
  <div>
    KEY :
    <input type='text' class='textbox1' maxlength="1" />
    <input type='text' class='textbox2' maxlength="1" />
    <input type='text' class='textbox3' maxlength="1" />
    <input type='text' class='textbox4' maxlength="1" />
    <input type='text' class='textbox5' maxlength="1" />
    <input type='text' class='textbox6' maxlength="1" />
    <input type='text' class='textbox7' maxlength="1" />
    <br />
    <br />
    <input type='text' class='textbox8' maxlength="2" />
    <input type='text' class='textbox9' maxlength="2" />
    <input type='text' class='textbox10' maxlength="2" />
    <input type='text' class='textbox11' maxlength="2" />
    <br />
