Vue.js 动态href

Question

So, I'm trying to create a dynamic href in a Vue component that can be edited in the App.vue file (without having to edit it in the component file).

Just like the name1, name2, name3 and name4 you can see in the file

<div class="navigationdrawer">
    <div id="mySidenav" class="sidenav">
        <a href="#">{{ name1 }}</a>
        <a href="#">{{ name2 }}</a>
        <a href="#">{{ name3 }}</a>
        <a href="#">{{ name4 }}</a>
    </div>
</div>

<script>
export default {
        name: 'NavigationDrawer',
        props: {
            msg: String,
            name1: String,
            name2: String,
            name3: String,
            name4: String,
            link1: String,
            link2: String,
            link3: String,
            link4: String
        }
</script>

When I put <a href= {{ link1 }}>{{ name1 }}</a> It works with {{ name1 }} but the {{ link1 }} part gives an error.

Mustaches cannot be used inside HTML attributes. Instead, use a v-bind directive:

<a v-bind:href="link1">{{ name1 }}</a>

or with shorthand

<a :href="link1">{{ name1 }}</a>

Also, I would suggest to use an array of links to make the component more dynamic.

<div class="navigationdrawer">
  <div id="mySidenav" class="sidenav">
    <a :href="link.href" v-for="link in links" :key="link.href">
      {{ link.name }}
    </a>
  </div>
</div>

links:

[
 { name: 'Name 1', href: 'http://name1.com' },
 { name: 'Name 2', href: 'http://name2.com' },
]
