Question

我的页面左侧有一组按钮。单击这些按钮时，它会显示一个div。我遇到了其中一个按钮的问题。一个名为'公告'。它可能是所有这些问题，但这是我尝试将内容放入的第一个div。我正在尝试添加一个表格。它正在做的是将下一个按钮的内容包含在公告中，反之亦然，对于进行它的按钮。我创建了一个JSfiddle来展示我在做什么。我的页面上的结果是一样的。它显示了这个

<div id='dues'>League Dues</div>

在公告div中。它还会显示我的<th>，但如果您点击公告并尝试重新发布，<th>就会消失。

为什么会这样？

我检查了你的jsfiddle代码，发现你使用过insertAfter。我已将其替换为html

此外，您还没有关闭公告的div元素，这会导致问题。

检查以下代码。

 jQuery(document).ready(function () {
                     $('.panel_out input').on('click', function(){
                        var id_to_show = '#' + this.id.replace('_button', '');
                        $(id_to_show).show().siblings().hide();
                    }).first().trigger('click');
$("input.arrowBtn").click(function(){
                    $(this).siblings('.arrow-left').remove();
                    $("<div class='arrow-left'></div>").html($(this));
                });
                });

HTML code：

    <div class="panel_out">
        <div class="panel">
            <input type='button' class="panel_buttons arrowBtn" id='user_requests_button' value='User Requests'>
            <input type='button' class="panel_buttons arrowBtn" id='message_center_button' value='Message Center'>
            <input type='button' class="panel_buttons arrowBtn" id='edit_rankings_button' value='Team Rankings'>
            <input type='button' class="panel_buttons arrowBtn" id='draft_order_button' value='Draft Order'>
            <input type='button' class="panel_buttons arrowBtn" id='draft_input_button' value='Draft Input'>
            <input type='button' class="panel_buttons arrowBtn" id='announcements_button' value='Announcements'>
            <input type='button' class="panel_buttons arrowBtn" id='dues_button' value='League Dues'>
        </div>
    </div>
    <div class="dashboard_selection">
        <div id="dashboard_welcome">Welcome to the Admin Dashboard</div>
        <div id='user_requests'>User Requests</div>
        <div id='message_center'>Message Center</div>
        <div id='edit_rankings'>gfg</div>
        <div id='draft_order'>Draft Order</div>
        <div id='draft_input'>Draft Input</div>
        <div id='announcements'>
            Current Announcements
                <table>
                    <tr>
                        <th>ID</th>
                        <th>Username</th>
                        <th>Message</th>
                        <th>Date</th>
                    </tr>
                    <tr>
                        <td><?php echo $announcements_id; ?></td>
                        <td><?php echo $announcements_username; ?></td>
                        <td><?php echo $announcements_messages; ?></td>
                        <td><?php echo $announcements_date; ?></td>
                    </tr>    
                </table>
</div>
        <div id='dues'>League Dues</div>
    </div>
