javascript - Bootstrap 手动折叠

Question

我有几个可折叠项目，当可折叠 div 打开并且用户单击另一个项目打开另一个可折叠 div 但前一个 div 没有关闭时，我遇到了一个问题。当用户单击打开另一个可折叠 div 的另一个项目时，如何关闭打开的可折叠 div。

我已经尝试过类似下面的东西

<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工作。实现我正在寻求的可折叠行为的最佳方法是什么？

请试试这个，

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

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