仅在移动视图 - Bootstrap 3上折叠DIV

Question

我有侧边栏搜索参数.我想仅在移动设备上对此DIV进行折叠功能.使用Bootstrap 3 - 最新版本.

这是HTML标记.

<div class="col-md-3 col-sm-4 SearchParameters">
            <h4 data-toggle="collapse" data-target="#search">Location</h4>
            <div class="col-md-12 sCheck no-gutter collapse" id="search">
                <h5>Lahore (254)</h5>
                <div class="col-md-12">
                    <form role="form">
                        <div class="checkbox checkbox-primary">
                            <input type="checkbox" id="ModelTown">
                            <label for="ModelTown">Model Town</label>
                        </div>
                        <div class="checkbox checkbox-primary">
                            <input type="checkbox" id="DHA">
                            <label for="DHA">DHA</label>
                        </div>
                        <div class="checkbox checkbox-primary">
                            <input type="checkbox" id="CG">
                            <label for="CG">Cavalry Ground</label>
                        </div>
                        <div class="checkbox checkbox-primary">
                            <input type="checkbox" id="Gulberg">
                            <label for="Gulberg">Gulberg</label>
                        </div>
                        <div class="checkbox checkbox-primary">
                            <input type="checkbox" id="Samnabad">
                            <label for="Samnabad">Samnabad</label>
                        </div>
                        <div class="checkbox checkbox-primary">
                            <input type="checkbox" id="AIT">
                            <label for="AIT">Allama Iqbal Town</label>
                        </div>
                        <div class="checkbox checkbox-primary">
                            <input type="checkbox" id="GardenTown">
                            <label for="GardenTown">Garden Town</label>
                        </div>
                        <div class="checkbox checkbox-primary">
                            <input type="checkbox" id="Township">
                            <label for="Township">Township</label>
                        </div>
                        <div class="checkbox checkbox-primary">
                            <input type="checkbox" id="FaisalTown">
                            <label for="FaisalTown">Faisal Town</label>
                        </div>
                        <a href="#">20 more locations</a>
                    </form>
                </div><!-- form-group -->
                <div class="clearfix"></div>
                <h5 class="second">Availability</h5>

                <div class="col-md-12 SelectDays">
                    <a href="#" class="Day">M</a>
                    <a href="#" class="Day">T</a>
                    <a href="#" class="Day active">W</a>
                    <a href="#" class="Day">Th</a>
                    <a href="#" class="Day">F</a>
                    <a href="#" class="Day">S</a>
                    <a href="#" class="Day">SU</a>
                </div><!-- SelectDays -->

                <div class="col-md-12 TimeSet">
                    <!-- timeFunction -->
                </div><!-- TimeSet -->

            </div><!-- col-md-12 -->
        </div><!-- SearchParameters -->

我使用SearchParameters DIV为代码赋予样式.

注意:我想只在移动设备上折叠"SearchParameters"div并用按钮打开它..应该只有1个div.我可以隐藏这个div并显示另一个在移动设备上可见的div,但这不是一个好方法.我想折叠这个div并仅在移动设备上按下按钮显示它.

Answer 1

你可以这样做:

<button class="visible-xs" data-toggle="collapse" data-target="#SearchParameters">Toggle it</button>

<div class="hidden-xs col-md-3 col-sm-4 SearchParameters" id="SearchParameters">
...

CSS:

#SearchParameters.in,
#SearchParameters.collapsing {
    display: block!important;
}

Answer 2

由于"in"类将可折叠元素定义为open,因此在移动设备上将其删除会导致折叠元素开始折叠.

例如

<button data-toggle="collapse" data-target="#collapsible">Show/Hide</button>
<div class="collapse in" id="collapsible">
    Content Here.
</div>
<div class="visible-xs" id="xs-check"></div>
<script>
if( $("#xs-check").is(":visible") )
    $("#collapsible").removeClass("in");
</script>
