v-for 循环数组可以是一个函数

html

1<view class="imgItem" v-for="(defaultItem, defaultIndex) in showMyopenGroupList(myCreateGroup.teamCount,myCreateGroup.userGroups.length)" :key="defaultIndex">
2</view>

js

1showMyopenGroupList(totalNum, num) {
2    let defaultNum = totalNum - num
3    let arr = []
4    for (let i = 0; i < defaultNum; i++) {
5	arr.push(i)
6	}
7    return arr
8},
