Vue Js Get Every nth Element/item of Array: To retrieve every nth element of an array in Vue.js, you can employ the array’s filter method along with the modulo operator. By applying the filter method and checking if the index of each element is divisible evenly by n (using the modulo operator), you can selectively obtain the desired elements from the array.
How can I retrieve every Nth element/item of an array in Vue js?
The code snippet provided demonstrates how to use Vue.js to get every nth element of an array.
The Vue instance is created with an array of numbers and a variable “nth” that represents the desired value of n. The computed property “everyNthElements” utilizes the filter method on the array and checks the index of each element.
Only elements whose index plus one is divisible evenly by the value of “nth” are included in the filtered result.
Vue Js Get Every Nth Element/Item Of Array Example
<div id="app">
<p>Array: {{array}}</p>
<p>Every nth Element:{{everyNthElements}}</p>
</div>
<script type="module">
const app = new Vue({
el: "#app",
data() {
return {
array: [1, 2, 3, 4, 5, 6, 7, 8, 9, 10],
nth: 2, // Set the desired value of n here
};
},
computed: {
everyNthElements() {
return this.array.filter((_, index) => (index + 1) % this.nth === 0);
},
}
});
</script>
