What is the best way to begin a v-for loop?
For instance, we have an array named "array" with the following values:
array = [dog, cat, e, f, g];
I am interested in using a v-for loop that will start looping through and only consider the first 3 values.
Thank you for your help!
To display only the first 3 elements of an array in Vue, you can create a computed property.
new Vue({
el: "#app",
template: '<ul><li v-for="item of subArray">{{ item }}</li></ul>',
data: {
array: ["one", "two", "three", "four", "five"]
},
computed: {
subArray(){ return this.array.slice(0,3) }
}
})<script src="https://cdn.jsdelivr.net/npm/vue/dist/vue.js"></script>
<div id="app"></div>Consider implementing a v-if condition to verify whether the position of the item is within the first three elements.
Simply utilize the included index functionality
<template v-for="(item, index) in list">
<p v-if="index <= 3">[[ index ]]</p>
</template>
and voila!
