在 BootstrapVue 中禁用侧边栏的滚动和处理 Close 方法

Question

我想问 2 个关于 BootstrapVue 中的 Sidebar 的问题。

打开边栏后禁用滚动
单击边栏外部时如何处理关闭方法（背景）

我正在使用 https://bootstrap-vue.org/docs/components/sidebar

<template>
  <div>
    <b-button v-b-toggle.sidebar-backdrop>Toggle sSidebar</b-button>
    <b-sidebar
      id="sidebar-backdrop"
      title="Sidebar with backdrop"
      backdrop
      shadow
    >
      <div class="px-3 py-2">
        <p>
          Cras mattis consectetur purus sit amet fermentum. Cras justo odio, dapibus ac facilisis
          in, egestas eget quam. Morbi leo risus, porta ac consectetur ac, vestibulum at eros.
        </p>
        <b-img src="https://picsum.photos/500/500/?image=54" fluid thumbnail></b-img>
      </div>
    </b-sidebar>
  </div>
</template>

谢谢你和感激。

您可以通过在正文中添加 bootstrap class overflow-hidden 来删除滚动条。

将方法挂接到边栏上的 @change 方法，该方法在显示和隐藏边栏时触发。

侧边栏还有一个 @hidden 事件，当侧边栏隐藏时会触发该事件。

new Vue({
  el: '#app',
  methods: {
    toggleBodyScrollbar(visible) {
      const body = document.getElementsByTagName('body')[0];

      if(visible)
        body.classList.add("overflow-hidden");
      else
        body.classList.remove("overflow-hidden");
    }
  }
})
