uniapp列表多選

選中並獲取值，實現的程式碼如下：

<template>
	<view class="index">
		<view class="new_box" style="margin-top: 20upx;">
			<view class="bbox">
				<view class="list-box" v-for="(item,index) in list" :key="index">
					<view class="list-ed">
						<image class="list-img" src="../../static/logo.png" mode="aspectFill"></image>
						<view class="list-right">
							<view class="list-head" @click="choice(index)">
								<view :class="[item.selected?'selde':'noselde']">{{item.selected?"已選擇":"選擇"}}<text :class="[item.selected?'selde-q':'noselde-q']"></text></view>
							</view>
							<view class="list-name">{{item.title}}</view>
							<view class="list-da">
								<view>課程：<text>{{item.course}}</text></view>
								<view>時長：<text>{{item.duration}}</text>分</view>
							</view>
						</view>
					</view>
				</view>
				<view class="sure" @click="sure">確認</view>
			</view>
		</view>
	</view>
</template>

<script>
	export default {
		data() {
			return {
				list: [{
						course_id: "001",
						title: "一個很長很長很長的標題一個很長很長很長的標題一個很長很長很長的標題一個很長很長很",

					},
				],
				selectId:[],
			};
		},
		methods: {
			//選擇課程
			choice(index){
				if(this.list[index].selected == true){
					this.list[index].selected = false;
					//取消選中時刪除陣列中的值
					for(var i = 0; i < this.selectId.length; i++){
					    if(this.selectId[i] === this.list[index].course_id){

					return false;
				}
				var listIds = this.selectId.join(",")
				console.log("提交的資料",listIds)
