Bootstrap在出现错误消息后保留当前选项卡

Question

我在Rails 4上使用引导标签浏览用户配置文件（设计）。如果显示错误消息，我想保持当前选项卡打开。

例如，当用户提交新密码但输入错误的当前密码时，将显示设计错误消息，但它会切换回第一个选项卡。

我已经让当前标签在刷新时保持活动状态：

<script>
    $(document).ready(function() {
    if(location.hash) {
        $('a[href=' + location.hash + ']').tab('show');
    }
    $(document.body).on("click", "a[data-toggle]", function(event) {
        location.hash = this.getAttribute("href");
    });
});
$(window).on('popstate', function() {
    var anchor = location.hash || $("a[data-toggle=tab]").first().attr("href");
    $('a[href=' + anchor + ']').tab('show');
});
</script>

但不是在出现错误消息时。这是我的标签设置......

<div class="row">
  <div class="col-md-8 col-md-offset-2">
    <ul class="nav nav-tabs" style="margin-top: 80px" id="myTab">
        <li class="active"><a data-toggle="tab" href="#sectionA">Your Answers</a></li>
        <li><a data-toggle="tab" href="#sectionB">Change Password</a></li>
        <li><a data-toggle="tab" href="#sectionC">Edit Profile</a></li>
