简介

前面把商品列表页的查询展示逻辑基本完成了。每个功能单独测试是没有问题了，但是连在一起呢？新增的功能是否会对以前的功能产生影响。

测试与修复

很遗憾，确实有bug。加入商品分页功能以后，我们试着点击价格筛选和排序，发现页面都错乱了。所以我们需要对GoodsList.vue进行如下修改：

<template>
  <div>
    <PageHeader></PageHeader>
    <PageBread>
      <span>Goods</span>
    </PageBread>
    <div class="accessory-result-page accessory-page">
      <div class="container">
        <div class="filter-nav">
          <span class="sortby">Sort by:</span>
          <a href="javascript:void(0)" class="default" :class="{'cur': sortChecked === 'default'}" @click="checkSort('default')">Default</a>
          <a href="javascript:void(0)" class="price" :class="{'cur': sortChecked === 'priceUp' ||  sortChecked === 'priceDown'}" @click="checkSort(isPriceUp?'priceDown':'priceUp')">Price
            <span v-if="isPriceArrowUp">↑</span>
            <span v-else>↓</span>
            <!--<svg class="icon icon-arrow-short">-->
              <!--<symbol id="icon-arrow-short" viewBox="0 0 25 32">-->
                <!--<title>arrow-short</title>-->
                <!--<path class="path1" d="M24.487 18.922l-1.948-1.948-8.904 8.904v-25.878h-2.783v25.878l-8.904-8.904-1.948 1.948 12.243 12.243z"></path>-->
              <!--</symbol>-->
              <!--<use xlink:href="#icon-arrow-short"></use>-->
            <!--</svg>-->
          </a>
          <a href="javascript:void(0)" class="filterby stopPop" @click="showFilterBy">Filter by</a>
        </div>
        <div class="accessory-result">
          <!-- filter -->
          <div class="filter stopPop" id="filter" :class="{'filterby-show': isShowFilterBy}">
            <dl class="filter-price">
              <dt>Price:</dt>
              <dd><a href="javascript:void(0)" :class="{'cur': priceChecked === 'all'}" @click="checkPriceFilter('all')">All</a></dd>
              <dd v-for="(item, index) in priceFilterList" :key="index">
                <a v-if="item.endPrice" href="javascript:void(0)" :class="{'cur': priceChecked === index}" @click="checkPriceFilter(index)">{{item.startPrice}} - {{item.endPrice}}</a>
                <a v-else href="javascript:void(0)" :class="{'cur': priceChecked === index}" @click="checkPriceFilter(index)">> {{item.startPrice}}</a>
              </dd>
            </dl>
          </div>

          <!-- search result accessories list -->
          <div class="accessory-list-wrap">

再看一看，是不是就正常了。这一章我就不上太多的图了，大家可以试着到处点一下，看看是否仍然有问题。
