How to use setInterval in a Vue component?
To use setInterval in a Vue component, we call it with a callback.
For instance, we write
<script>
//...
export default {
//...
methods: {
todo() {
this.intervalid = setInterval(() => {
this.changes = (Math.random() * 100).toFixed(2) + "%";
}, 3000);
},
},
//...
};
</script>
to call setInterval with a function that sets the value of this.changes every 3 seconds.
We call it with an arrow function so this is still the Vue component instance inside the setInterval callback.
