intl tel输入无法与jQuery 3.6.0一起正常工作

Question

我有两个代码，一个是旧代码，它运行得很好，然后我决定升级到jquery 3.6.0，但我遇到了一个问题，代码停止工作，所以我从这里得到了一个新代码，但它运行不正常。

旧代码

var telInput = $("#phone"),
  errorMsg = $("#error-msg"),
  validMsg = $("#valid-msg");
// initialise plugin
telInput.intlTelInput({
  utilsScript: "https://cdnjs.cloudflare.com/ajax/libs/intl-tel-input/11.0.4/js/utils.js"
});
var reset = function() {
  telInput.removeClass("error");
  errorMsg.addClass("hide");
  validMsg.addClass("hide");
};
// on blur: validate
telInput.blur(function() {
  reset();
  if ($.trim(telInput.val())) {
    if (telInput.intlTelInput("isValidNumber")) {
      validMsg.removeClass("hide");
      var getCode = telInput.intlTelInput('getSelectedCountryData').dialCode;
      alert(getCode);
    } else {
      telInput.addClass("error");
      errorMsg.removeClass("hide");
    }
  }
});
// on keyup / change flag: reset
telInput.on("keyup change", reset);

<script type="text/javascript" src="//code.jquery.com/jquery-2.1.3.js"></script>
<link rel="stylesheet" type="text/css" href="https://cdnjs.cloudflare.com/ajax/libs/intl-tel-input/6.4.1/css/intlTelInput.css">
<script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/intl-tel-input/6.4.1/js/intlTelInput.min.js"></script>
<input id="phone" type="tel">
<span id="valid-msg" class="hide">✓ Valid</span>
<span id="error-msg" class="hide">Invalid number</span>

在jsbin上：https://jsbin.com/heqokumase/edit?html，js，输出

这个代码运行得很好，例如，除了(数字和+(之外，它不允许任何输入。如果用户用数字键入国家代码，它会自动删除国家代码。

新代码

var input = document.querySelector("#registration-phone-number");
var errorMap = ["Invalid number", "Invalid country code", "Too short", "Too long", "Invalid number"];
window.addEventListener("load", function() {
  errorMsg = document.querySelector("#error-msg"),
    validMsg = document.querySelector("#valid-msg");
  var iti = window.intlTelInput(input, {
    utilsScript: "https://cdnjs.cloudflare.com/ajax/libs/intl-tel-input/17.0.15/js/utils.js"
  });
  window.intlTelInput(input, {
    // allowDropdown: false,
    // autoHideDialCode: false,
    // autoPlaceholder: "off",
    // dropdownContainer: document.body,
    // excludeCountries: ["us"],
    // formatOnDisplay: false,
    geoIpLookup: function(callback) {
      $.get("https://ipinfo.io", function() {}, "jsonp").always(function(resp) {
        var countryCode = (resp && resp.country) ? resp.country : "";
        callback(countryCode);
      });
    },
    hiddenInput: "full_number",
    initialCountry: "auto",
    // localizedCountries: { 'de': 'Deutschland' },
    // nationalMode: false,
    // onlyCountries: ['us', 'gb', 'ch', 'ca', 'do'],
    placeholderNumberType: "MOBILE",
    // preferredCountries: ['cn', 'jp'],
    separateDialCode: true,
    utilsScript: "https://cdnjs.cloudflare.com/ajax/libs/intl-tel-input/17.0.15/js/utils.js",
  });
  $(validMsg).hide();
  input.addEventListener('blur', function() {
    reset();
    if (input.value.trim()) {
      if (iti.isValidNumber()) {
        $(validMsg).show();
      } else {
        $(input).addClass('form-control-danger');
        var errorCode = iti.getValidationError();
        errorMsg.innerHTML = errorMap[errorCode];
        $(errorMsg).show();
      }
    }
  });
  input.addEventListener('change', reset);
  input.addEventListener('keyup', reset);
});

var reset = function() {
  $(input).removeClass('form-control-danger');
  errorMsg.innerHTML = "";
  $(errorMsg).hide();
  $(validMsg).hide();
};

<input id="registration-phone-number" type="tel">
<span id="valid-msg" class="hide">✓ Valid</span>
<span id="error-msg" class="hide">Invalid number</span>

它起作用，但它不将输入仅限于(数字和+(，也不会在数字输入时自动删除国家代码；"太短"；尤其是在加载开始时，它会自动获得用户所在的国家/地区，但正如我所说，如果你写的数字没有国家/地区代码，就会出现错误"；"太短"；除非您再次选择国家/地区，否则它将显示为有效。

如何通过jquery的新更新和intltel输入的新更新使新代码像旧代码一样完美地工作？

我解决了它，下面是任何想要它的人的代码：(

     var input = document.querySelector("#phone"),
        errorMap = ["Invalid number", "Invalid country code", "Too short", "Too long", "Invalid number"],
        result = document.querySelector("#result");
    
    
    window.addEventListener("load", function () {
      
      
      errorMsg = document.querySelector("#error-msg");
    
    function getIp(callback) {
     fetch('https://ipinfo.io', { headers: { 'Accept': 'application/json' }})
       .then((resp) => resp.json())
       .catch(() => {
         return {
           country: '',
         };
       })
       .then((resp) => callback(resp.country));
    }
      
    var iti = window.intlTelInput(input, {
                // allowDropdown: false,
                // dropdownContainer: document.body,
                // excludeCountries: ["us"],
                hiddenInput: "full_number",                         
                nationalMode: false,
                formatOnDisplay: true,           
                separateDialCode: true,
                autoHideDialCode: true,

      input.addEventListener('keyup', formatIntlTelInput);
    input.addEventListener('change', formatIntlTelInput);
    
    function formatIntlTelInput() {
        if (typeof intlTelInputUtils !== 'undefined') { // utils are lazy loaded, so must check
            var currentText = iti.getNumber(intlTelInputUtils.numberFormat.E164);
            if (typeof currentText === 'string') { // sometimes the currentText is an object :)
                iti.setNumber(currentText); // will autoformat because of formatOnDisplay=true
            }
        }
    }
       
      
             
           input.addEventListener('keyup', function () {
