Vue Js Get Middle Element of Array:In Vue.js, to obtain the middle element of an array, you can follow these steps: Retrieve the array’s length using the length property.
Divide the length by 2 to determine the index of the middle element. To account for array indices starting at 0, use the Math.floor() function to round down the calculated index value.
Access the element at the computed index using bracket notation, i.e., array[index]. Finally, assign the middle element to a variable for further use.
How can I retrieve the middle element of an array using Vue js?
This Vue.js code displays an array and calculates the middle element of the array. The array [1, 2, 3, 4, 5, 6, 7]
is stored in the myArray
data property. The middleItem
data property is initially set to null
.
When the Vue instance is mounted (mounted
lifecycle hook), it calculates the index of the middle element by dividing the length of the array by 2 and rounding it down using Math.floor()
. The calculated index is then used to retrieve the middle element from the array, and it is assigned to the middleItem
property.
Vue Js Get Middle Element of Array Example
<div id="app">
<p>Array: {{ myArray }}</p>
<p>Middle Item: {{ middleItem }}</p>
</div>
<script type="module">
const app = new Vue({
el: "#app",
data() {
return {
myArray: [1, 2, 3, 4, 5, 6, 7,],
middleItem: null
};
},
mounted() {
const middleIndex = Math.floor(this.myArray.length / 2);
this.middleItem = this.myArray[middleIndex];
}
});
</script>
