Adding ids dynamically to href elements in Vue.js

As a newcomer, I am facing an issue with dynamically adding an id to my href tag.

Below is the code snippet:

  <div class="col-md-6"  v-for="Product in data">
      <div class="panel panel-default" >
          <div class="panel-heading">
              {{ Product.name }}
          </div>
          <div class="panel-body" v-for = "Category in Product.Categories">
              <div class="panel-group" id="accordion">
                  <div class="panel panel-default">
                      <div class="panel-heading">
                          <h4 class="panel-title">

                              <!--SEE HREF BELOW -->
                              <a data-toggle="collapse" data-parent="#accordion" href="#{{Category._id}}"  >
                                   {{ Category.name }}</a>
                           </h4>
                       </div>

                       <!-- SEE ID BELOW AS WELL -->
                       <div id="{{ Category._id }}" class="panel-collapse collapse">
                           <div class="panel-body"></div>
                       </div>
                 </div>
            </div>    
       </div>
 </div>

I am attempting to assign _id to the href attribute in

<a data-toggle="collapse" data-parent="#accordion" href="#{{Category._id}}">

, and using the same Id for the

<div id="{{ Category._id }}" class="panel-collapse collapse">

tag mentioned above the href.

Any suggestions on how I can achieve this?

Thank you!

Answer №1

Give this a shot: :href="`#${Category._id}`"

In Vue, the colon signals to treat the value as JavaScript rather than a plain string. The backticks allow for string interpolation, enabling you to include the preceding hash symbol.

In Vue 2, you cannot use interpolation directly. Instead, you need to bind your properties to a data object or compute them using v-bind (or the colon shorthand) like this:

<a data-toggle="collapse" data-parent="#accordion" v-bind:href="`#${Category._id}`">

An approach using a computed property would be:

new Vue({
  el: '#app',
  computed:{
    href(){
      return '#' + this.Category._id
    }
  },
  data(){
    return {
      Category: {
        _id: 1
      }
    }
  }
})

This way, you can update it dynamically.
