使用 jquery [auto country by IP/intl-tel-input jquery library] 获取国家代码的输入值

Question

I need to submit COUNTRY CODE to URL based on the selected country value.

Im using Intl-Tel-Input for this: https://github.com/jackocnr/intl-tel-input

Here is HTML code:

<form id="redirform" method="GET" action="#link"> 
                                <div class="gtd-form-wrapper">
                                    <input type="hidden" id="country" name="country">

                                <div class="form-group">
                                    <input name="phone" pattern="[0-9]*" id="phone" class="f w-input" data-value-missing="Use numbers only. No country code! No whitespaces!" required="required" placeholder="Phone">
                                </div> 

                                <div class="form-group">
                                    <button class="submit-button w-button gtd-form-submit" type="submit">SUBMIT</button>
                                </div>
                            </form> 

Here is jQuery:

        var input = document.querySelector("#phone");
        window.intlTelInput(input, {
            initialCountry: "auto",
            geoIpLookup: function(success, failure) {
                $.get("https://ipinfo.io/", function() {}, "jsonp").always(function(resp) {
                var countryCode = (resp && resp.country) ? resp.country : "";
                success(countryCode);
                });
            },
        });

        input.addEventListener('countrychange', function () {
                $('#country').val(iti.getSelectedCountryData().iso2);
            });

        $('#redirform').on('submit',function(){
        var $input = $(this).find("input[name=country]");
            $('#country').val(iti.getSelectedCountryData().iso2);
        });

Seems you need to get the selected country value from the intl input. You don't need to add country input in HTML.

    var intl = window.intlTelInput(input, {
        initialCountry: "auto",
        geoIpLookup: function(success, failure) {
            $.get("https://ipinfo.io/", function() {}, "jsonp").always(function(resp) {
            var countryCode = (resp && resp.country) ? resp.country : "";
            success(countryCode);
            });
        },
    });

    $('#redirform').on('submit', function(e) {
        e.preventDefault();
        var countryData = iti.getSelectedCountryData();

        var form = $('#form');
        form.append($("<input>").attr("type", "hidden").attr("name", "country").val(countryData.iso2));

        form.submit();
    });

while the form is submitting, there is a hidden input is created and the value is set, so you don't need to worry about it.

Because you have told you to need to get the country value into URL, the form will submit as GET because the method of the form is GET.

Hope this will help you. thanks.
