Question

我试图在提交时从intlTelInput插件获得扩展，但由于某种原因它返回空。以下是一个示例：https://jsfiddle.net/msfk6top/

代码：

<link rel="stylesheet" href="https://intl-tel-input.com/node_modules/bootstrap/dist/css/bootstrap.min.css?7">
<link rel="stylesheet" href="https://intl-tel-input.com/node_modules/intl-tel-input/build/css/intlTelInput.css?37">

<form id="my_form">
    <input name="phone" type="tel" id="phone" class="form-control">
    <input type="submit">
</form>

<!-- use old jquery so demo works in IE -->
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<script src="https://intl-tel-input.com/node_modules/intl-tel-input/build/js/intlTelInput.js?60"></script>

<script>
    $("#phone").intlTelInput();

    $("#my_form").submit(function () {
        alert($("#phone").intlTelInput("getExtension"));
    });
</script>

知道为什么它没有返回所选择的扩展名吗？

Answer 1

初始化插件时，您需要指定utilsScript选项才能使getExtension生效。

在您的plunker中，请执行：

$("#phone").intlTelInput({utilsScript:'https://intl-tel-input.com/node_modules/intl-tel-input/build/js/utils.js'});

utilsScript应该是intl-tel-input插件中包含的utils.js script的路径。
