uniapp——点赞、取消点赞

案例

更新点赞状态，而不是每次都刷新整个列表。避免页面闪烁，提升用户体验

代码

<view class="funcBtn zan" @click="onZan(index,item.id)">
	<image src="/static/images/circle/zan.png" mode="aspectFill"
		v-if="!item.like_status"></image>
	<image src="/static/images/circle/zan2.png" mode="aspectFill"
		v-if="item.like_status"></image>
	<view class="nums">{{item.like_num}}</view>
</view>

// 点赞
function onZan(index, likeId) {
	if (list.value[index].like_status) {
		list.value[index].like_status = false
		list.value[index].like_num--
		likeImport(likeId)
	} else {
		list.value[index].like_status = true
		list.value[index].like_num++
		likeImport(likeId)
	}
}
//接口
function likeImport(likeId) {
	api.getLikeSave({
		release_id: likeId
	}).then(res => {
		if (res.code == 1) {

		}
	})
}
