:id="'obj-'x"
needs to be this to work
:id="'obj-' + x"
same works with classes
:class="'lang-' + x"
but i prefer template strings if possible
:class="`lang-${x}`"
This is how you do it
<p v-for="(x, index) in languages" :class="'lang-'+x" :key="index" v-on:click="call(x)" style="border:1px solid black; padding: 10px;">{{x}}</p>
