I just want to write class plan__part_${this.res}
within element
v-bind:
:key="item.id"
></div>```

As you can see in following snippet your code working fine, don't use this
in template:
new Vue({
el: '#demo',
data() {
return {
res: '1',
item: {id: 1}
}
}
})
Vue.config.productionTip = false
Vue.config.devtools = false
.plan__part_1{
background: violet;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.17/vue.js"></script>
<div id="demo">
<div :class="{[`plan__part_${res}`]: true }" :key="item.id">
{{ res }}
</div>
</div>
<iframe name="sif1" sandbox="allow-forms allow-modals allow-scripts" frameborder="0"></iframe>
CodePudding user response:
For this case if your current implementation is not working then you can try using computed
v-bind:
:key="item.id"
></div>
and in
computed: {
getClass() {
if(this.flag) return `plan__part_${this.res}`;
return '';
}
Note: this.flag
is actually the boolean that you have used in the template
