php - TypeError：无法读取未定义选项卡上的属性“nodeName”

问题描述

我正在尝试使用下拉菜单显示选项卡。选项卡工作正常，但错误仍然存​​在，当我在下拉菜单中选择选项卡菜单时，它不会关闭下拉菜单，但会显示相应的选项卡并显示错误。

<div class="dropdown">
    <button class="btn dropdown-toggle dropdown-tabs" style="background-color: #fdcd3d; color: #000;" type="button" data-toggle="dropdown">Achievers
        <span class="caret"></span>
    </button>
    <ul class="dropdown-menu" id="myTab" role="tablist">
        <li id="#achiever" name="Achievers">
            <a class="dropdown-link" name="#achiever" data-toggle="tab" href="#achiever" role="tab" aria-controls="home" aria-expanded="true">Achievers</a>
        </li>
        <li id="#articles" name="Articles">
            <a class="dropdown-link" name="#articles" data-toggle="tab" href="#articles" role="tab" aria-controls="profile">Articles</a>
        </li>
        <li id="#bulletins" name="Bulletins">
            <a class="dropdown-link" data-toggle="tab" role="tab" aria-controls="profile">Bulletins</a>
        </li> 
        <li id="#events" name="Events">
            <a class="dropdown-link" data-toggle="tab" href="#events" role="tab" aria-controls="profile">Events</a>
        </li>             
        <li id="#jobs" name="Jobs">
            <a class="dropdown-link" data-toggle="tab" href="#jobs" role="tab" aria-controls="profile">Jobs</a>
        </li>                 

    </ul>
</div>

我的 js 下拉菜单代码

$(document).ready(function(){

    $('.dropdown-menu > li > a').click(function(e){
        var id = $(this).parent().attr('id');
        var text = $(this).parent().attr('name');
        // var tab = $('.tab-pane').attr('id');
        e.preventDefault();
        $('.dropdown-tabs').text(text);

        if(id != null){
            $('a[href="' + id + '"]').tab('show');
        }

    });

});

解决方案

id 必须以a-zorA-Z开头，不能以#.

然后在 中$('a[href="' + id + '"]').tab('show');，您需要更改为$('a[href="#' + id + '"]').tab('show');

$(document).ready(function(){
  $('.dropdown-menu > a').click(function(e){
    var text = $(this).text();
    $('.dropdown-toggle').text(text);
    $(this).tab('show');
    $(this).removeClass("active");
  });

});
