Bootstrap Dropdown Active在悬停时打开，并在单击时链接 [英] Bootstrap Dropdown Active open on hover and link on click

问题描述

我一直在尝试修改django-oscar的导航栏菜单. http://latest.oscarcommerce.com/en-gb/

I have been trying to modify django-oscar's navbar menu. http://latest.oscarcommerce.com/en-gb/

我不知道的是，菜单浏览商店"在主页加载页面时仍然保持打开状态，而在其他所有页面上单击时都打开.我不知道为什么会这样.有没有办法使其悬停打开并在点击时添加<a>标签?

What I can't figure out is that the menu 'browse store' remains open on page load on homepage but opens on click on all other pages. I can't figure out why that would happen. Is there a way to to make it open on hover and to add an <a> tag on click?

这是与奥斯卡文档中相关部分有关的html模板-

This is the html template concerning the related part in oscar's documentation -

<div class="navbar-collapse primary-collapse collapse">
        {% block nav_dropdown %}
            <ul id="browse" class="nav navbar-nav">
                <li class="dropdown active {% if expand_dropdown %}open{% endif %}">
                    <a href="#" class="dropdown-toggle" {% if not expand_dropdown %} data-toggle="dropdown"{% endif %}>
                        <span class="nav-line-1">Shop by</span><span class="nav-line-2">  Category</span>
                        <b class="caret"></b>
                    </a>
                    <ul class="dropdown-menu" data-navigation="dropdown-menu">
                        {% category_tree depth=2 as tree_categories %}
                        <li><a tabindex="-1" href="{% url 'catalogue:index' %}">{% trans "All products" %}</a></li>
                        {% if tree_categories %}
                            <li class="divider"></li>
                            {% for tree_category, info in tree_categories %}
                                {% if info.has_children %}
                                    <li class="dropdown-submenu">
                                        <a tabindex="-1" href="{{ tree_category.get_absolute_url }}">{{ tree_category.name }}</a>
                                        <ul class="dropdown-menu">
                                        {% else %}
                                            <li><a tabindex="-1" href="{{ tree_category.get_absolute_url }}">{{ tree_category.name }}</a></li>
                                        {% endif %}

                                        {% for close in info.num_to_close %}
                                            </ul></li>
                                        {% endfor %}
                            {% endfor %}
                        {% endif %}
                    </ul>
                </li>
                {% block nav_extra %}
                {% endblock %}
            </ul>
        {% endblock %}

    </div><!-- /navbar-collapse -->
</div>

推荐答案

主菜单执行此操作的原因是，在<li class="dropdown active"和其他页面上没有open属性，我刚刚检查了站点，这迫使菜单打开.

The reason the home menu is doing that is because you have a atribute of open on the <li class="dropdown active" and on the other pages you don't, I just checked the site and that is forcing the menu open.

关于您的问题，它的行为与其他页面不同，请点击打开.这是因为您忘记在<li class="dropdown active"下方的a标记上添加data-toggle="dropdown".菜单代码应与主页上的以下代码相同:

About your issue with it not behaving the same as the other pages and opening on click. This is becuase you forgot to add the data-toggle="dropdown" on the a tag just beneath <li class="dropdown active". The menu code should be as per the following on the homepage:

<ul id="browse" class="nav">
    <li class="dropdown active"> 
      <a href="#" class="dropdown-toggle" data-toggle="dropdown">Browse store<b class="caret"></b></a>
        <ul class="dropdown-menu" data-navigation="dropdown-menu" style="width: 212px;">
            <li><a tabindex="-1" href="/en-gb/catalogue/">All products</a>
            </li>
            <li class="divider"></li>
            <li class="dropdown-submenu"> 
                <a tabindex="-1" href="/en-gb/catalogue/category/books_1/">Books</a>
                <ul class="dropdown-menu">
                    <li><a tabindex="-1" href="/en-gb/catalogue/category/books/fiction_2/">Fiction</a>
                    </li>
                    <li><a tabindex="-1" href="/en-gb/catalogue/category/books/non-fiction_4/">Non-Fiction</a>
                    </li>
                </ul>
            </li>
            <li class="divider"></li>
            <li><a href="/en-gb/offers/">Offers</a>
            </li>
        </ul>
    </li>
</ul>

您想在悬停时打开它，我认为您可以使用JQuery进行调查，并可能检查菜单是否悬停在上面，然后添加如下所示的打开类:

You wanted to have it open on hover, i think yo ucan look into using JQuery and maybe checking if the menu has been hovered on and then adding the open class like this:

$('.dropdown').hover(function(){ 
  $('.dropdown-toggle', this).trigger('click'); 
});
