Learn the method for incorporating a changing name into a radio button with Vue.js

How do I dynamically name radio buttons?

<tr v-for="user in users">
    <td>
        <input type="radio" :name="groups_[[ user.id ]]" v-bind:value="photographer" v-bind:checked="user.group.name == photographer"> <label>photographer</label>

        <input type="radio" :name="groups_[[ user.id ]]" v-bind:value="client" v-bind:checked="user.group.name == client"> <label>client</label>
    </td>
</tr>

Upon implementing the code above, an error message appears:

The property or method "groups_" is not defined on the instance but referenced during render. Make sure to declare reactive data properties in the data option.

Answer №1

To convert the groups_ into a string, simply add single quotes around it. Next, use the plus sign (+) to join the groups_ string with the user id.

<input type="radio" :name="'groups_' + user.id" v-bind:value="photographer" v-bind:checked="user.group.name == photographer"> <label>photographer</label>

<input type="radio" :name="'groups_' + user.id" v-bind:value="client" v-bind:checked="user.group.name == client"> <label>client</label>
