Is there a way to display this code using Vuejs and v-for?
I'm interested in displaying data beginning with index 0, followed by every third index up to index 15. The total length of the data is 16.
For example, like this: 0,3,6,9,12,15
for(i = 0; i < data.length; i+=3) {}
To optimize the data, you can preprocess it in the computed property:
new Vue({
el: "#app",
data() {
return {
items: [0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15],
}
},
computed: {
everyThird: function() {
const thirds = []
for(let i = 0; i < this.items.length; i+=3) {
thirds.push(this.items[i])
}
return thirds;
}
},
})<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.17/vue.js"></script>
<div id="app">
<li v-for="(item, i) in everyThird" :key="i">
{{ item }}
</li>
</div>If you want to filter elements in an array based on a specific condition, you can achieve this by using a computed property. Create an array within the computed property that only includes elements with indexes divisible by 3. Then, utilize this filtered array in your v-for loop. Below is an example of how you can implement this in your Vue.js component:
<div>
<li v-for="(item, index) in elementInThirdPlace" :key="index">
{{ item }}
</li></div>
export default {
data () {
return { items: [1,2,3,4,5,6,6] }
},
computed: {
elementInThirdPlace () {
return this.items.filter((element, index) => index % 3 == 0 )
}
}
}
}
