【问题描述】：

我有一个按钮，当点击它时会显示一个引导模式模态包含侧边栏选项卡。

我的问题是当我关闭模式并通过单击按钮再次打开它时，它将使用最后一个激活的选项卡打开一旦我关闭模式并再次打开模式而不重新加载页面，我希望激活的选项卡成为第一个选项卡。

bootstrap 使用的是哪个版本的？

【解决方案1】：

只需使用 Bootstrap 默认方法 modal 和 tab

$('#MyDetailsModal').on('show.bs.modal', function (event) { 
    $(this).find('.nav a:first').tab('show');
})

<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script>


<div>
    <a href="#" class="popupLink btn btn-info btn-lg" data-toggle="modal" data-target="#MyDetailsModal">MyDetailsModal
    </a>
</div>

<div class="modal" id="MyDetailsModal" tabindex="-1" role="dialog" arialabelledby="myDetailsModal" aria-hidden="true">
    <div class="modal-dialog modal-details" role="document">
        <div class="modal-content modal-details">
            <div class="modal-header">
                <button type="button" class="close close-button" data-dismiss="modal" aria-label="Close" id="btnId"> </button>
            </div>

            <div class="modal-body">
                <div class=" tabs-left" id="modal-tabs">
                    <ul class="nav nav-tabs">
                        <li class="active">
                            <a href="#personal" data-toggle="tab">personal</a>

                        <li>
