无法从 Vue 路由器中删除下划线-link

Question

我想我几乎尝试了所有尝试从 router-link 中删除下划线的方法。

这是我的代码：

<router-link :to="{name: 'Plan'}">
   <div>Plan Your Trip</div>
      <div class='expander'>
      <router-link :to="{name: 'Plan'}">COVID-19</router-link>
      <router-link :to="{name: 'Plan'}">Visa</router-link>
      <router-link :to="{name: 'Plan'}">Essentials</router-link>
   </div>
</router-link>

我正在尝试仅从 子链接 中删除下划线。

我尝试过的事情：

行内样式

<router-link style="text-decoration: none !important;" :to="{name: 'Plan'}">COVID-19</router-link>

赋值class

<router-link class="sub-link" :to="{name: 'Plan'}">COVID-19</router-link>

<style scoped>
   .sub-link{text-decoration: none !important;}
</style>

声明标签

<router-link tag="div" :to="{name: 'Plan'}">COVID-19</router-link>

<style scoped>
   div{text-decoration: none !important;}
</style>

分配单独的标签 + 为该标签声明class

<router-link :to="{name: 'Plan'}">
   <div class="sub-link">COVID-19</div>
</router-link>

这些只是几个列表，我确实尝试了我能想到的所有可能的方法...我是否缺少有关自定义 Vue 的内容router-link？

Answer 1

当您检查 DOM 中的 router-link 时，您会发现它是一个 a 标签。请记住，即使删除了初始下划线，当您将鼠标悬停在路由器 link 文本上时，也会出现下划线。

使用这个片段

<router-link :to="{name: 'Plan'}">
   <div>Plan Your Trip</div>
      <div class='expander'>
      <router-link :to="{name: 'Plan'}">COVID-19</router-link>
      <router-link :to="{name: 'Plan'}">Visa</router-link>
      <router-link :to="{name: 'Plan'}">Essentials</router-link>
   </div>
</router-link>

.expander a {
  text-decoration: none;
}

.expander a:hover {
  text-decoration: none;
}

外部 router-link 正在将 text-decoration: underline 应用于其 inner-text，内部 router-link 也将 text-decoration: underline 应用于其 inner-text .

此刻你的内在 router-links 基本上应用了双下划线。

您需要将其从两者中删除。如果您需要另一个元素具有 text-decoration: underline，则单独为该元素设置它。

Answer 3

使用display: inline-block;text-decoration:none;，诀窍是显示：inline-block;.

Css spec 州

For block containers that establish an inline formatting context, the decorations are propagated to an anonymous inline element that wraps all the in-flow inline-level children of the block container. For all other elements it is propagated to any in-flow children. Note that text decorations are not propagated to floating and absolutely positioned descendants, nor to the contents of atomic inline-level descendants such as inline blocks and inline tables.

示例：代码中的 link COVID-19 将删除下划线。

<router-link :to="{name: 'Plan'}">
   <div>Plan Your Trip</div>
      <div class='expander'>
      <router-link :to="{name: 'Plan'}" style="display: inline-block;text-decoration:none;">COVID-19</router-link>
      <router-link :to="{name: 'Plan'}">Visa</router-link>
      <router-link :to="{name: 'Plan'}">Essentials</router-link>
   </div>
</router-link>

下面是一个演示：

let Layout = {
  template: `<div>
  <h4>Layout Page </h4>
  <router-link to="/contact">
  <div>
    <p>Links<p>
    <router-link to="/contact/add" style="display: inline-block;text-decoration:none;">Add1</router-link>
    <router-link to="/addcontact">Add2</router-link>
  </div>
  </router-link>
  <router-view></router-view>
  </div>`
};
let Home = {
  template: '<div>this is the home page. Go to <router-link to="/contact">contact</router-link> </div>'
};

let ContactList = {
  // add <router-view> in order to load children route of path='/contact'
  template: '<div>this is contact list, click <router-link to="/contact/add">Add Contact In sub Router-View</router-link> here to add contact<p><router-view></router-view></p> Or Click <router-link to="/addcontact">Add Contact In Current Router-View</router-link></div>'
};

let ContactAdd = {
  template: '<div>Contact Add</div>'
}

let router = new VueRouter({
  routes: [{
    path: '/',
    redirect: 'home',
    component: Layout,
    children: [{
        path: 'home',
        component: Home
      },
      {
        path: 'contact',
        component: ContactList,
        children: [{
          path: 'add',
          component: ContactAdd
        }]
      },
      {
        path: 'addcontact', // or move ContactAdd as direct child route of path=`/`
        component: ContactAdd,
      }
    ]
  }]
});

new Vue({
  el: '#app',
  components: {
    'App': {
      template: '<div><router-view></router-view></div>'
    },
  },
  router
});
