Bootstrap 24 小时弹出一次的模态

Question

我在 SharePoint 网站上创建了一个 Bootstrap 模式弹出框。页面加载时出现 I 弹出窗口。我还添加了设置 cookie 的代码，使弹出窗口只出现一次，但这不起作用。你能解决这个问题吗？下面是我的代码：

        <a href="#" type="button" data-toggle="modal" data-target="#myModal"><strong>Read more</strong></a> 

        <div class="modal fade" id="myModal" role="dialog" aria-hidden="true" style="display: none;"> 
        <div class="modal-dialog" style="width: 1000px;"> 
        <div class="modal-content"> 
        <div class="modal-body"> 

        TEXT HERE!

        <div class="modal-footer">
        <button class="btn btn-default" type="button" data-dismiss="modal">Close</button></div> 
        </div>
        </div>
        </div> 
        </div> 

        <script type="text/javascript">
        $(window).on('load',function(){
        $('#myModal').modal('show');
        });
        </script>
        </script>

        <script type="text/javascript">

        $(document).ready(function() {
        if ($.cookie('pop') == null) {
        $('#myModal').modal('show');
        $.cookie('pop', '1');
        }
        });</script>

Answer 1

当用户访问站点时检查cookie是否已经存在，如果不存在则创建一个1天--

if (typeof $.cookie('modal_shown') === 'undefined'){ // no cookie

    $('#myModal').modal('show');
    $.cookie('modal_shown', 'yes', { expires: 1 }); // set cookie expiry to 1 day

} else { // have cookie
    // do something
}

还要确保在代码中包含您正在使用的插件。

示例测试演示，你可以试试。

<!-- Modal -->
<div class="modal fade" id="exampleModalLong" tabindex="-1" role="dialog" aria-labelledby="exampleModalLongTitle" aria-hidden="true">
    <div class="modal-dialog" role="document">
        <div class="modal-content">
            <div class="modal-header">
                <h5 class="modal-title" id="exampleModalLongTitle">Modal title</h5>
                <button type="button" class="close" data-dismiss="modal" aria-label="Close">
                    <span aria-hidden="true">&times;</span>
                </button>
            </div>
            <div class="modal-body">
                ...
            </div>
            <div class="modal-footer">
                <button type="button" class="btn btn-secondary" data-dismiss="modal">Close</button>
                <button type="button" class="btn btn-primary">Save changes</button>
            </div>
        </div>
    </div>
</div>
<script type="text/javascript"
        src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.5.0/jquery.min.js">

<script type="text/javascript"

</script>
<script type="text/javascript">
    $(function () {
        console.log($.cookie('pop'));
        if (!$.cookie('pop')) {
            $('#exampleModalLong').modal('show');
            $.cookie('pop', '1');
        }
    })

</script>
