How to only show slot if it has content with Vue.js?
To only show slot if it has content with Vue.js, we can check the this.$slots property in our component.
For instance, we write
<template>
<div id="app">
<div class="panel-footer" v-if="hasFooterSlot">
<slot name="footer"></slot>
</div>
</div>
</template>
<script>
//...
export default {
//...
computed: {
hasFooterSlot() {
return !!this.$slots.footer;
},
},
//...
};
</script>
to check if the footer slot is added with !!this.$slots.footer.
We put this in the hasFooterSlot computed property, so we can use that in our template with v-if to conditionally display the footer slot with
<div class="panel-footer" v-if="hasFooterSlot">
<slot name="footer"></slot>
</div>
Conclusion
To only show slot if it has content with Vue.js, we can check the this.$slots property in our component.
