Uni-App中实现多选样式

<template>
		<view class="label-con u-justify-start u-items-center u-flex-wrap">
			<view class="label-list" :class="{'active': isActive.indexOf(index)!=-1}" v-for="(item,index) in tagList" :key="index"
			 @click="addMemberTags(index)">
				{{ item.tag_name }}
			</view>
		</view>
</template>

addMemberTags(index) {
	var that = this;
	if (that.isActive.indexOf(index) == -1) {
		console.log(index) //打印下标
		that.isActive.push(index); //选中添加到数组里
	} else {
		that.isActive.splice(that.isActive.indexOf(index), 1); //取消
	}
}
