前几天小项目，没考虑周全，让后端改接口，改成数组中包含对象中包含数组的形式，后来越琢磨越不对，后台把所有数据放在了一个对象里，我拿弹窗数据不好拿，索性又改了回来，把后端折腾够呛，自己也折腾够呛，发上来，以示警戒

改前拿数据

<div class='your-container'>

			<div>综合排序</div>
			<div class="sortHot" @click="mostHot"><p>最热</p><div class="sortImg"><img src="../../assets/imgs/mosthot.png" alt=""></div></div>
			<div class="sortHot" @click="mostNew"><p>最新</p><div class="sortImg"><img src="../../assets/imgs/mostview.png" alt=""></div></div>
			<div class="adhibition" @click="adhibition(0)">应用</div>
			<div class="adhibition" @click="adhibition(1)">算法</div>
		</div>

		<vue-scroll :ops="ops">
					<div class='your-content'>
							<ul class="listBox"  @handle-resize="handleResize">
								<li v-for="(item,index) in list" :key="index" class="lis">
										<div class="listIcon">

												<div class="details" @click="detailsClick">详情</div>
											</div>
											<div class="spans" v-for='(value,key,idx) in item' :key='idx'>
												<p v-if='Object.prototype.toString.call(value).slice(8,-1)  == "Array"'><span>{{value[0]}}:</span><span class="lastname">{{value[1]}}</span></p>

								</li>
							</ul>
						</div>
        </vue-scroll>
				<detailsPopUp @manage="manshow" v-if="manageshow"/>
    </div>

改后
