How to pass a value from Vue data to href?

You need to use v-bind: or its alias :. For example,

<a v-bind:href="'/job/'+ r.id">

or

<a :href="'/job/' + r.id">

Or you can do that with ES6 template literal:

<a :href="`/job/${r.id}`"

If you want to display links coming from your state or store in Vue 2.0, you can do like this:

<a v-bind:href="''"> {{ url_link }} </a>
