Exploring the application of javascript method within a Vue template

Currently, I am attempting to extract a numeric value from the end of a URL. However, I am encountering an error in doing so. It has been a while since I last worked with Vue, but I know that we can use methods/functions to achieve the desired outcome. Could someone please point out where my mistake lies?

<ul>
    <li  v-for="(character, index) in characters" :key="index">
     <router-link :to="'/characters'+ character.url.split("/").pop()">
        {{character.name}}
      </router-link>
    </li>
  </ul>

Answer №1

Providing an illustration to assist with understanding:

new Vue({
  el: '#app',
  data: {
    character: {
      url: 'https://jsonplaceholder.typicode.com/todos/101'
    }
  },
})
<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.17/vue.js"></script>

<div id="app">
  <div v-html="`/characters/${character.url.split('/').pop()}`"></div>
  <div> {{ `/characters/${character.url.split('/').pop()}` }}</div>
</div>

This approach utilizes string literals (known as Template literals or Template strings) in order to enhance code readability and minimize the use of quotation marks and concatenation operators like +.
