VueJS: How to Access the Previous Item in v-repeat
In v2 of vue.js, you need to this form of v-for to get the index:
v-for="(item, index) in items"You can then use items[index - 1] to get the previous value (making sure your function checks it isn't undefined).
You can use the $index variable along with entries like this
<td>@{{ getCostPerDay(entries[$index-1]) + ' €' }}</td>For more reading about $index have a look at Displaying Lists
<div v-for="grade, i in grades"> <input v-model="grade.name"> <input v-model.number="grade.percent"> <div v-if="i > 0 && grade.percent > grades[i - 1].percent"> Invalid: percent must be lower than previous grade </div></div>
