首页开发

TabControl 的封装

因TabControl组件在home和category页面都可以用到，所以可以在公共组件的content下创建tabControl文件夹进行封装

<template>
  <div class="tab-control">
    <div
      v-for="(item, index) in titles"
      :key="index"
      class="tab-control-item"
      //当索引值与currentIndex相同时，文字高亮
      :class="{ active: index === currentIndex }" 
      @click="itemClick(index)" 
    >
      <span>{{ item }}</span>
    </div>
  </div>
</template>

<script>
export default {
  name: "TabControl",
  props: {
    titles: {
      type: Array,
      default() {
        return [];
      },
    },
  },
  data() {
    return {
      currentIndex: 0,
    };
  },
  methods: {
    itemClick(index) {
      this.currentIndex = index; //设置点击的span为活跃状态
    },
  },
};
</script>

<style>
.tab-control {
  display: flex;
  text-align: center;
  font-size: 15px;
  height: 40px;
  line-height: 40px;
  background-color: #fff;
}
.tab-control-item {
  flex: 1;
}
.tab-control-item span {
  padding: 5px;
}
.active {
  color: var(--color-height-text);
}
.active span {
  border-bottom: 3px solid var(--color-tint);
}
</style>

组件的导入规范

<script>
    //公共组件放一起
import NavBar from "components/common/navbar/NavBar";
import TabControl from "components/content/tabControl/TabControl";
    //home页面相关组件放一起
import HomeSwiper from "./childComps/HomeSwiper";
import RecommendView from "./childComps/RecommendView";
import FeatureView from "./childComps/FeatureView";
    //导入方法放一起
import { getHomeMultidata } from "network/home";

export default {
  name: "Home",
  components: {
    HomeSwiper,
    RecommendView,
    FeatureView,
    //挂载组件规范与上述一致
    NavBar,
    TabControl,
  },
    ...

TabControl停留效果实现

不要在TabControl组件里设置样式，要在Home.vue设置样式，因为只有在Home页面有这个效果

.tab-control {
  display: sticky;
  top: 44px;
}
