我使用oninput屬性使input字段在插入時(shí)自動(dòng)生成千位分隔符，并且有效。但我想要實(shí)現(xiàn)的是，它也允許放置點(diǎn).字符，因?yàn)槲蚁氆@得兩位小數(shù)，到目前為止這是我的代碼不起作用：function separator(input) {   let nums = input.value.replace(/,/g, '');  if(!nums)return;  input.value = parseFloat(nums).toLocaleString(); }function addition() {  var number1 = document.getElementById('number1').value;  var number2 = document.getElementById('number2').value;  number1 = number1.replace(/[,]+/g, '');  number2 = number2.replace(/[,]+/g, '');    if (number1 == "")    number1 = 0;  if (number2 == "")    number2 = 0;      var result = parseFloat(number1) + parseFloat(number2);  result = result.toFixed(2);  if (!isNaN(result)) {      document.getElementById('total').value = result;  }  document.getElementById('total').onchange();}<table>  <tr>    <td><input onkeyup="addition()" oninput="separator(this)" type="text" id="number1" placeholder="123,456.16"></td>    <td>+</td>    <td><input onkeyup="addition()" oninput="separator(this)" type="text" id="number2" placeholder="123,456.16"></td>    <td>=</td>    <td><input onchange="separator(this);" type="text" name="total" id="total" placeholder="total" readonly></td>  </tr></table>即使我已經(jīng)設(shè)置了input帶有屬性的字段type="text"，它仍然不能放置點(diǎn).字符。如何解決這個(gè)問題？
