javascript - 只打开一个 Accordion 面板 vue.js/bootstrap vue

Question

构建了一个 bootstrap-vue Accordion 并且一切都按预期工作但是，我只是添加了展开所有/折叠所有按钮，这些按钮也按我预期的那样运行但现在我的问题是当我直接点击任何 Accordion 面板时它们全部打开。有没有办法让他们只打开点击的面板？

html:

   <div class="container container-accordion-one">
      <!--expand all / collapse all row -->
      <div class="row row-expand-collapse">
        <div class="offset-md-1 col-expand-collapse">
          <ul class="list-expand-collapse">
            <li><a href="#/" @click="showCollapse = true" class="font__card-body">Expand All</a></li>
            <li><a href="#/" @click="showCollapse = false" class="font__card-body">Collapse All</a></li>
          </ul>
        </div>
      </div>
      <!--end: expand all / collapse all row -->
      <div class="row">
        <div class="offset-md-1 accordion-style-one">
          <div role="tablist">
            <b-card no-body class="">
              <b-card-header href="#" v-b-toggle.accordion-1 header-tag="header" class="accordion-header" role="tab">
                <p class="font__accordion-header">Accordion 1</p>
                <i class="fal fa-plus accordionClosed" />
                <i class="fal fa-minus accordionOpen" />
              </b-card-header>
              <b-collapse id="accordion-1" v-model="showCollapse" role="tabpanel">
                <b-card-body>
                  <p>Lorem ipsum dolor sit amet, consectetur adipisicing elit. Architecto distinctio enim fugit, inventore odio odit perferendis quas quo veritatis voluptate.</p>
                </b-card-body>
              </b-collapse>
            </b-card>

            <b-card no-body class="">
              <b-card-header href="#" v-b-toggle.accordion-2 header-tag="header" class="accordion-header" role="tab">
                <p class=" font__accordion-header">Accordion 2</p>
                <i class="fal fa-plus accordionClosed" />
                <i class="fal fa-minus accordionOpen" />
              </b-card-header>
              <b-collapse id="accordion-2" v-model="showCollapse" role="tabpanel">
                <b-card-body>
                  <p>Lorem ipsum dolor sit amet, consectetur adipisicing elit. Architecto distinctio enim fugit, inventore odio odit perferendis quas quo veritatis voluptate.</p>
                </b-card-body>
              </b-collapse>
            </b-card>

            <b-card no-body class="">
              <b-card-header href="#" v-b-toggle.accordion-3 header-tag="header" class="accordion-header" role="tab">
                <p class=" font__accordion-header">Accordion 3</p>
                <i class="fal fa-plus accordionClosed" />
                <i class="fal fa-minus accordionOpen" />
              </b-card-header>
              <b-collapse id="accordion-3" v-model="showCollapse" role="tabpanel">
                <b-card-body>

                </b-card-body>
              </b-collapse>
            </b-card>
          </div>
        </div>
      </div>
    </div>

js:

export default {
  name: 'm',
  components: {
   LinksTo
  },
  data() {
    return {
      showCollapse: false
    };
  }
};

由于您希望每个折叠都能够单独打开或关闭，因此您需要为每个折叠设置一个 v-model 变量。在下文中，我使用数组来存储折叠状态:

<template>
  <div>
    <b-button @click="expandAll">Expand all</b-button>
    <b-button @click="collapseAll">Collapse all</b-button>

    <b-button block v-b-toggle.accordion-1 class="mt-2">Accordion 1</b-button>
    <b-collapse id="accordion-1" v-model="collapseStates[0]">
      <div>Lorem ipsum dolor sit amet.</div>
    </b-collapse>

    <b-button block v-b-toggle.accordion-2 class="mt-2">Accordion 2</b-button>
    <b-collapse id="accordion-2" v-model="collapseStates[1]">
      <div>Lorem ipsum dolor sit amet.</div>
    </b-collapse>

    <b-button block v-b-toggle.accordion-3 class="mt-2">Accordion 3</b-button>
    <b-collapse id="accordion-3" v-model="collapseStates[2]">
      <div>Lorem ipsum dolor sit amet.</div>
    </b-collapse>
  </div>
</template>

<script>
export default {
  data() {
    return {
      collapseStates: [false, false, false]
    }
  },
  methods: {
    expandAll() {
      this.collapseStates = this.collapseStates.map(x => true)
    },
    collapseAll() {
      this.collapseStates = this.collapseStates.map(x => false)
    }
  }
}
</script>
