Question

我有几个可折叠项，当可折叠div打开时，当用户单击另一个可打开另一个可折叠div但上一个div不能关闭的项目时，我面临一个问题。当用户单击另一个可打开另一个可折叠div的项目时，如何关闭打开的可折叠div。

我尝试了以下类似的方法

<li><a class="layer-item" data-toggle="collapse" href="#baseLayer" role="button" aria-expanded="false" aria-controls="baseLayer" onclick="selectLayer('base')" id="base-layer-btn" title="Base layer">Base layer</a></li>
<li><a class="layer-item" data-toggle="collapse" href="#soilLayer" role="button" aria-expanded="false" aria-controls="soilLayer" onclick="selectLayer('soil')" id="soil-layer-btn" title="Soil layers">Soil layers</a></li>

<div class="collapse" id="baseLayer">...</div>
<div class="collapse" id="soilLayer">...</div>

在我的脚本标签内

<script>
  function selectLayer(layer){
    if(layer == 'soil'){
      $('#baseLayer').collapse('hide')
    }else if(layer == 'base'){
      $('#soilLayer').collapse('hide')
    }
  }
</script>

但是此解决方案无法按预期正常运行。实现我正在寻求的可折叠行为的最佳方法是什么？

Answer 1

请尝试这个

function selectLayer(layer){
    if(layer == 'soil'){
      $('#soilLayer').toggleClass('show')
    }else if(layer == 'base'){
      $('#baseLayer').toggleClass('show')
    }
  }

<li><a class="layer-item"  href="#soilLayer" role="button" aria-expanded="false" aria-controls="soilLayer" onclick="selectLayer('soil')" id="soil-layer-btn" title="Soil layers">Soil layers</a></li>

<div class="collapse" id="baseLayer">Base</div>
<div class="collapse" id="soilLayer">soil</div>

添加一个自定义jquery方法即可解决！

/* On click of any of your list items, only the selected one will have the class of 
`show` and all other will automatically get the class of `hide` */

 $('.layer-item').click(() => {
    $('.collapse').collapse('hide');
  });

<ul>
  <li><a class="layer-item text-primary" data-toggle="collapse" href="#baseLayer" role="button" aria-expanded="false" aria-controls="baseLayer" id="base-layer-btn" title="Base layer">Base layer</a></li>
  <li><a class="layer-item text-warning" data-toggle="collapse" href="#soilLayer" role="button" aria-expanded="false" aria-controls="soilLayer" id="soil-layer-btn" title="Soil layers">Soil layers</a></li>
</ul>


<div class="collapse" id="baseLayer">
  <h1 class="bg-primary">Base Layer</h1>
</div>
<div class="collapse" id="soilLayer">
  <h1 class="bg-warning">Soil Layer</h1>
</div>
