如何在按钮点击时关闭bootstrap下拉菜单？

Question

我有一个引导下拉菜单,我打开并让它保持打开状态,当我使用我放在其中的网格时,我可以在下拉区域外单击时关闭下拉列表,但我想将其关闭按钮点击事件..

这是下拉列表的html

<div class="dropdown">
    <button class="btn dropdown-toggle col-md-3" type="button" data-toggle="dropdown">
        Select Category
        <span class="caret"></span>
    </button>
    <ul class="dropdown-menu col-md-7" onClick="event.stopPropagation();">
        <div id="MaterialGridList" style="height:440px;"></div>
        <button type="button" id="btnFilter" class="btn btn-sm btn-success">Filter</button>
    </ul>
</div>

正如您在下拉菜单的onClick事件中看到的那样,它会保持打开状态.所以我想做的是在btnFilter点击事件上关闭它.有任何想法吗？

Answer 1

你可以使用里面有按钮的toggle功能.dropdown:

$('#btnFilter').click(function() {
  $(this).parents('.dropdown').find('button.dropdown-toggle').dropdown('toggle')
});

<div class="dropdown">
    <button class="btn dropdown-toggle col-md-3" type="button" data-toggle="dropdown">
        Select Category
        <span class="caret"></span>
    </button>
    <ul class="dropdown-menu col-md-7" onClick="event.stopPropagation();">
        <div id="MaterialGridList" style="height:440px;"></div>
        <button type="button" id="btnFilter" class="btn btn-sm btn-success">Filter</button>
    </ul>
</div>

只需data-toggle="dropdown"在要关闭菜单的元素上添加标签即可。

<button type="button" id="btnFilter" class="btn btn-sm btn-success" data-toggle="dropdown">Filter</button>
