javascript - 从 DOM 中删除 bootstrap Modal

Question

我正在编写一段代码，以便在用户通过单击触发事件后动态加载部分内容。

案例场景是:当用户点击帖子时，它将打开一个modal并显示详细 View ，该 View 是使用链接中的slug动态生成的内容。但是，当用户关闭 modal 时，我需要从 DOM 中删除模态。目前我只能隐藏它，但我需要删除它。

这是我的代码。

PHP Laravel HTML 标记 ():

<div class="content-blocks blog hidex">

        <section class="content">
            <div class="block-content">
                <h3 class="block-title">My Blog</h3>
                <div id="post-list" class="col-md-10 col-md-offset-1">

                    {% set posts = blogPosts.posts %}

                    {% for post in posts %}
                    <div class="post">

                        <div class="post-thumbnail">
                            {% if post.featured_images.count %}
                            {% set image = post.featured_images|first %}
                            <a class="open-post" href="{{'blog-post'|page}}">
                                <img
                                        data-src="{{ image.filename }}"
                                        src="{{ image.path }}"
                                        alt="{{ image.description }}"
                                        style="max-width: 100%"/>

                            </a>
                            {% endif %}
                        </div>
                        <div class="post-title">
                            <a class="open-post" href="{{ post.url }}"><h2>{{ post.title }}</h2></a>
                            <p class="post-info">


                                <span class="post-author">Posted by {{ post.user.first_name}} </span>
                                <span class="slash"></span>
                                <span class="post-date">on {{ post.published_at|date('M d, Y') }}</span>
                                <span class="slash"></span>
                                {% if post.categories.count %} in {% endif %}
                                {% for category in post.categories %}
                                <span class="post-category">{{ category.name }}</span>
                                {% if not loop.last %}, {% endif %}
                                {% endfor %}
                            </p>
                        </div>
                        <div class="post-body">
                            <p>{{ post.summary }}</p>
                            <a class="btn open-post" href="{{ post.url }}">Read More</a>
                        </div>
                    </div>
                    {% endfor %}

                    <div class="text-center">
                        {% if posts.lastPage > 1 %}
                        <ul class="pagination">
                            {% if posts.currentPage > 1 %}
                            <li>
                                <a href="{{ this.page.baseFileName|page({ (pageParam): (posts.currentPage-1) }) }}"
                                   aria-label="Previous">
                                    <span aria-hidden="true">&laquo;</span>
                                </a></li>
                            {% endif %}

                            {% for page in 1..posts.lastPage %}
                            <li class="{{ posts.currentPage == page ? 'active' : null }}">
                                <a href="{{ this.page.baseFileName|page({ (pageParam): page }) }}">{{ page }}</a>
                            </li>
                            {% endfor %}

                            {% if posts.lastPage > posts.currentPage %}
                            <li><a href="{{ this.page.baseFileName|page({ (pageParam): (posts.currentPage+1) }) }}"
                                   aria-label="Next">
                                <span aria-hidden="true">&raquo;</span>
                            </a>
                            </li>
                            {% endif %}
                        </ul>
                        {% endif %}
                    </div>
                </div>
            </div>
        </section>
    </div>

JavaScript:

//Blog post Modal
    $('.open-post').on('click', function(){
        var postUrl = $(this).attr("href");

        var post = '<div class="modal" id="post-modal"><div class="inline-menu-container"><a id="modal-close" class="close" data-dismiss="modal"><span aria-hidden="true">&times;</span></a></div><div class="modal-dialog"><div class="modal-content"></div></div></div>';

        $(post).modal({
          remote: postUrl
        })

        return false;
    });
// close the modal
   $('#close').on( 'click', function() {
      $('.name-block').removeClass('reverse');
      $('.name-block-container').removeClass('reverse');
      $('.menu-blocks').removeClass('hidex');
      $('.content-blocks').removeClass('showx');
      $('.content-blocks').addClass('hidex');
      $('.inline-menu-container').removeClass('showx');
      $('.inline-menu-container').addClass('hidex');
      $('.menu-item').removeClass('active');
    });

DOM 中 Javascript 代码的结果:

<div class="modal in" id="post-modal" style="display: block; padding-left: 0px;">
    <div class="inline-menu-container">
    <a id="modal-close" class="close" data-dismiss="modal"><span aria-hidden="true">×</span></a>
</div>
<div class="modal-dialog">
   <div class="modal-content">
   /// all the dynamic content in the modal
   </div>
</div>

现在我需要删除这个结果而不刷新页面。更新:这是关闭 modal 后在 Inspect 中的 HTML 中的外观:

注意:我尝试使用 #post-modal id 从 DOM 中删除模态内容，但没有成功。另外，我还没有找到使用 Delegate 的示例，而模式元素和内容是在加载“DOM”后完全由 javascript 添加的。

Answer 1

Bind an event然后remove() .

$('.modal').on('hidden.bs.modal', function () {
    $(this).remove();
});

或

$('.modal').on('hidden.bs.modal', function () {
    $('.modal').remove();
});
