VueJS关闭路线改变的汉堡菜单

Question

我有一个简单的VueJS应用程序和Bootstrap的导航栏:

<template>
  <header id="header">
    <nav class="navbar mynavbar navbar-fixed-top">
      <div class="container">
        <div class="navbar-header">
          <button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#navbar-collapse">
            <span class="sr-only">Toggle navigation</span>
            <span class="icon-bar"></span>
            <span class="icon-bar"></span>
            <span class="icon-bar"></span>
          </button>
          <a class="logo" href="index.html"><img src="images/logo.png" alt=""></a>
        </div>

        <div class="collapse navbar-collapse" id="navbar-collapse">
          <ul class="nav navbar-nav navbar-right">
            <li><router-link to="/home"><a>Home</a></router-link></li>
             <li><router-link to="/about"><a>About Us</a></router-link></li>
          </ul>
        </div><!-- /.navbar-collapse -->
      </div><!-- /.container -->
    </nav>
  </header>
</template>

现在我想确保在更改路径时,Bootstrap菜单关闭.完成此任务的最佳方法是什么？

Answer 1

无需 Bootstrap 和 jQuery，可以使用类切换和观察路由变化轻松实现。

<a role="button" class="navbar-burger" aria-label="menu" aria-expanded="false" 
    @click="toggledNav = !toggledNav"
>
   <span aria-hidden="true"></span>
   <span aria-hidden="true"></span>
   <span aria-hidden="true"></span>
</a>

脚本：

export default {
  data () {
    return {
      toggledNav: false
    }
  },
  watch: {
    '$route' () {
      this.toggledNav = false
    }
  }
}

Answer 2

router-link您可以直接查看$route属性以进行更改,而不是向每个人添加事件处理程序:

<script>
export default {
  watch: {
    '$route' () {
      $('#navbar-collapse').collapse('hide');
    }
  }
}
</script>

你可以尝试一下：

<template>
    <header id="header">
        <nav class="navbar mynavbar navbar-fixed-top">
            <div class="container">
                <div class="navbar-header">
                <button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#navbar-collapse">
                    <span class="sr-only">Toggle navigation</span>
                    <span class="icon-bar"></span>
                    <span class="icon-bar"></span>
                    <span class="icon-bar"></span>
                </button>
                <a class="logo" href="index.html"><img src="images/logo.png" alt=""></a>
                </div>

                <div class="collapse navbar-collapse" id="navbar-collapse">
                    <ul class="nav navbar-nav navbar-right">
                        <li><router-link @click.native="closeMenu()" to="/home"><a>Home</a></router-link></li>
                        <li><router-link @click.native="closeMenu()" to="/about"><a>About Us</a></router-link></li>
                    </ul>
                </div><!-- /.navbar-collapse -->
            </div><!-- /.container -->
        </nav>
    </header>
</template>
<script>
    export default {
        methods: {
            closeMenu() {
                $('#navbar-collapse').collapse('hide');
            }
        }
    }
</script>
