初始化后如何更新选项或更改货币

Question

我正在使用 https://github.com/autoNumeric/autoNumeric/blob/master/README.md#options-update

并且不知道如何更新 AutoNumeric 中的选项

所以预期的结果是根据我的选择更改货币

但是显示错误update is not a function

还是我错过了有关我一直在使用的更新的某些信息？

document.getElementById('anPrice_set').addEventListener('change',autoNumericLoad)
var an_obj

function autoNumericLoad() {
  var elemPrice = document.getElementById("anPrice_set")
  var priceSelect = elemPrice.options[elemPrice.selectedIndex].value
  var elemsPrice = document.querySelectorAll('[name="price"], #amount')
  if (AutoNumeric.isManagedByAutoNumeric(elemsPrice[0])) {
   an_obj.update(AutoNumeric.getPredefinedOptions()[priceSelect]) //**
  } else {
   an_obj = AutoNumeric.multiple('[name="price"], #amount', AutoNumeric.getPredefinedOptions()[priceSelect])
  }
}

document.addEventListener('DOMContentLoaded',() => {
autoNumericLoad()
document.getElementById('anPrice_set').addEventListener('change',autoNumericLoad)
})

<script src="https://unpkg.com/autonumeric@4.6.0/dist/autoNumeric.min.js"></script>
<div>
  <label for="anPrice_set">*Currency*</label>
  <select id="anPrice_set">

查看将 an_obj 分配给 Autonumeric 实例所需的文档，例如：

const an_obj = new AutoNumeric(domElement);

然后您就可以为 an_obj

致电 update
