我一直在使用Twitter Bootstrap进行下拉菜单,但问题是我使菜单可以移动而不是OnClick切换,是否有可能使这个菜单OnClick切换崩溃像我之前做的那样只能在其他触控设备上使用?

HOVERABLE

                <a class="nav-link dropdown" href="#">
          Dropdown link
        </a>
                <div class="dropdown-menu">
                    <a class="dropdown-item" href="#">1</a>
                    <a class="dropdown-item" href="#">2</a>
                    <a class="dropdown-item" href="#">3</a>
                    <a class="dropdown-item" href="#">4</a>
                    <a class="dropdown-item" href="#">5</a>
                </div>
            </li>
        </ul>
    </div>
</nav>

<style>
    .dropdown-menu {}

    .dropdown:hover .dropdown-menu {
        display: block;
        margin-top: 0;
    }
</style>

在基本引导代码中,我们将data-toggle="dropdown"id="dropdownMenuButton" aria-labelledby="dropdownMenuButton"

放在一起

所以我想知道是否可以在Touch设备上再次使用Basic!

您可以使用@media查询和CSS中与Bootstrap相同的断点,并仅将hover应用于非移动设备断点:

@media only screen and (min-width : 320px) {
    /* Custom, iPhone Retina */    
}

@media only screen and (min-width : 480px) {
    /* Extra Small Devices, Phones */ 
}

@media only screen and (min-width : 768px) {
    /* Small Devices, Tablets */
}

/* Medium Devices, Desktops, Large Devices, Wide Screens */
@media only screen and (min-width : 992px) {
    .dropdown:hover .dropdown-menu {
        display: block;
        margin-top: 0;
    }
}

这是基于Bootstrap 3断点。 这将导致悬停仅对屏幕产生影响,宽度超过992px
