壁纸小程序Vue3(首页布局)

1.创建一个公共目录common来存放css和images

App.vue中引用

<style lang="scss">

/*每个页面公共css */

@import 'common/style/common-style.scss';

</style>

2.渲染轮播图

<template>
	<view class="homeLayout">
      <view class="banner">
        <swiper indicator-dots indicator-color="rgba(255,255,255,0.5)"
          indicator-active-color="#fff" autoplay
          circular
        >
          <swiper-item v-for="item in 3" >
              <image src="../../common/images/lxja.webp" mode="widthFix"></image>
          </swiper-item>
        </swiper>
      </view>
	</view>
</template>

<script setup>

	
</script>

<style lang="scss" scoped>
	.homeLayout{
    .banner{
      width: 750rpx;
      padding: 30rpx 0;
      swiper{
        width: 750rpx;
        height: 340rpx;
      
        // swiper-item{}
        //简化
        &-item{
          width: 100%;
          height: 100%;
          padding: 0 30rpx;
          image{
            width: 100%;
            height: 100%;
            border-radius: 10rpx;
          }
        }
      }
    }
  }
</style>

3.公告的轮播

  <view class="notice">
          <view class="left">
              <uni-icons type="sound-filled" size="20" color="#28b389"></uni-icons>
              <text class="text">公告</text>
          </view>
          <view class="center">
              <swiper vertical autoplay interval="1500" duration="300" circular>
                    <swiper-item v-for="item in 4">文字内容文字内容文字内容文字内容文字内容文字内容</swiper-item>
              </swiper>
          </view>
          <view class="right">
                <uni-icons type="right" size="16" color="#333"></uni-icons>
          </view>
          
      </view>

  .notice{
      width: 690rpx;
      height: 80rpx;
      line-height: 80rpx;
      background: #f9f9f9;
      margin: 0 auto;
      border-radius: 80rpx;
      display: flex;
      .left{
        width: 140rpx;
        display: flex;
        align-items: center;
        justify-content: center;
        .text{
          color: #28b389;
          font-weight: 600;
          font-size: 28rpx;
        }
      }
      .center{
        flex: 1;
        swiper{
          height: 100%;
          &-item{
            height: 100%;
            font-size: 30rpx;
            color: #666;
            //超出的文字用...替换
            overflow: hidden;
            white-space: nowrap;
            text-overflow: ellipsis;
          }
        }
      }
      .right{
        width: 70rpx;
        display: flex;
        align-items: center;
        justify-content: center;
      }
    }

4.渲染公告下的内容

创建公共标题组件common-title

 <view class="select">
          <common-title></common-title>
          <view class="content">
              <scroll-view scroll-x>
                <view class="box" v-for="item in 8">
                    <image src="../../common/images/lxja.webp" mode="aspectFill"></image>
                </view>
              </scroll-view>
          </view>
      </view>

将元素的display属性设置为inline-block可以让元素既有行内元素可以一行显示多个的特性，又有块级元素可以设置宽高的特性。

.select{
      padding-top: 50rpx;
      .content{
        width: 720rpx;
        margin-left: 30rpx;
        margin-top: 30rpx;
        scroll-view{
          white-space: nowrap;
          .box{
            width: 200rpx;
            height: 430rpx;
            display: inline-block;
            margin-right: 15rpx;
            image{
              width: 100%;
              height: 100%;
              border-radius: 10rpx;
            }
          }
          .box:last-child{
            margin-right: 30rpx;
          }
        }
      }
    }

5.引入插槽定义公共标题模块

common-title

<template>
  <view class="common-title">
      <view class="name">
        <!-- 插槽 -->
        <slot name="name"></slot>
      </view>
      <view class="custom">
        <slot name="custom"></slot>
      </view>
  </view>
</template>

<script setup>
 
</script>

<style lang="scss" scoped>
.common-title{
  display: flex;
  justify-content: space-between;
  align-items: center;
  padding: 0 30rpx;
  .name{
    font-size: 40rpx;
  }
}
</style>

index.vue

  <view class="select">
          <common-title>
              <template #name>每日推荐</template>
              <template #custom>
                <view class="date">
                    <uni-icons type="calendar" size="18" color="#28b389"></uni-icons>
                    <view>
                        <uni-dateformat :date="Date.now()" format="dd日"></uni-dateformat>
                    </view>
                </view>
              </template>
          </common-title>
          <view class="content">
              <scroll-view scroll-x>
                <view class="box" v-for="item in 8">
                    <image src="../../common/images/lxja.webp" mode="aspectFill"></image>
                </view>
              </scroll-view>
          </view>
      </view>
      
      <view class="theme">
          <common-title>
            <template #name>专题精选</template>
            <template #custom>
              <navigator url="" class="more">More+</navigator>
            </template>
          </common-title>
      </view>

6.渲染专题精选

index.vue

 <view class="theme">
          <common-title>
            <template #name>专题精选</template>
            <template #custom>
              <navigator url="" class="more">More+</navigator>
            </template>
          </common-title>
          <view class="content">
              <theme-item v-for="item in 8"></theme-item>
          </view>
      </view>

.theme{
        padding-top: 50rpx;
        .more{
          font-size: 32rpx;
          color: #888;
        }
        .content{
          margin-top: 30rpx;
          padding: 0 30rpx;
          //网格布局
          display: grid;
          //每个元素中间有一个间隙
          gap: 15rpx;
          //一行展示三个每行平均分配
          grid-template-columns: repeat(3,1fr);
        }
    }

新创建一个组件them-item

<template>
  <view class="themeTtem">
      <navigator url="" class="box">
        <image class="pic" src="https://img1.baidu.com/it/u=871832137,2572636834&fm=253&fmt=auto&app=120&f=JPEG?w=800&h=1198" mode="aspectFill"></image>
        <view class="mask">盛世美颜</view>
        <view class="tab">3天前更新</view>
      </navigator>
  </view>
</template>

.themeTtem{

.box{

height: 340rpx;
border-radius: 10rpx;
//不加overflow:圆角显示不出来

overflow: hidden;

position: relative;

.pic{

width: 100%;

height: 100%;

}

.mask{

width: 100%;

height: 70rpx;

position: absolute;

bottom: 0;

left: 0;

//磨砂透明
background: rgba(0,0,0,0.2);
color: #fff;
display: flex;
align-items: center;
justify-content: center;
//模糊滤镜
backdrop-filter: blur(20rpx);
font-weight: 600;
font-size: 30rpx;

}

.tab{

position: absolute;

left: 0;

top: 0;

background: rgba(250,129,90,0.7);

backdrop-filter: blur(20rpx);

color: #fff;

font-size: 22rpx;

padding: 6rpx 14rpx;

//左上 右上 右下 左下
border-radius: 0 0 20rpx 0;
//网格文字最小为12px,要想小于12px,可进行如下操作
//缩放
transform: scale(0.8);
//以左上角基准偏移
transform-origin: left top;

}

}

}

1)渲染更多标题

index.vue
<view class="theme">

<common-title>

<template #name>专题精选</template>

<template #custom>

<navigator url="" class="more">More+</navigator>

</template>

</common-title>

<view class="content">
<theme-item v-for="item in 8"></theme-item>
<theme-item :isMore="true"></theme-item>
</view>

</view>
them-item
<view class="themeTtem">

<navigator url="" class="box" v-if="!isMore">

<image class="pic" src="https://img1.baidu.com/it/u=871832137,2572636834\&fm=253\&fmt=auto\&app=120\&f=JPEG?w=800\&h=1198" mode="aspectFill"></image>

<view class="mask">盛世美颜</view>

<view class="tab">3天前更新</view>

</navigator>

<navigator url="" class="box more" v-else>
<image class="pic" src="https://img1.baidu.com/it/u=351608013,944758287\&fm=253\&fmt=auto\&app=138\&f=JPEG?w=500\&h=751" mode="aspectFill"></image>
<view class="mask">
<uni-icons type="more-filled" size="34" color="#fff"></uni-icons>
<view class="text">更多</view>
</view>
</navigator>

</view>

.box.more{

.mask{

width: 100%;

height: 100%;

flex-direction: column;

}

.text{

font-size: 28rpx;

}

}
