uniapp 滑动切换

说明：本案例的样式基于colorui组件库 感兴趣的小伙伴能够看下教程 colorui组件库开发文档或者csdn的文档，顺便再分享下 colorui的群资源

最近项目中须要用到滑动切换的效果，本身懒得写就去网上找了下，发现网上的也不靠谱，不是样式错乱就是其余bug，反正到你的电脑上就是各类bug般的存在，恰好趁着过年的时间把这个完整的效果给小伙伴们陈列下个人gitee

效果图

组件封装

• swiper-tab.vue

• html

<template>
	<view class="">
	  <scroll-view scroll-x class="nav bg-white" style="scrollStyle">
	    <view class="flex text-center">
	      <view class="cu-item flex-sub" :style="scrollItemStyle" @tap="tabtap(index)" :class="tabIndex==index?'text-blue cur':''" v-for="(tab,index) in tabBars" :key="tab.id">{{tab.name}} {{tab.num?tab.num:''}}</view></view>
	  </scroll-view>
	</view>
</template>

• css

<style>
	.uni-swiper-tab {
		border-bottom:1upx solid #EEEEEE;
	}
	.swiper-tab-list {
		color:#969696;
		font-weight:bold;
	}
	.uni-tab-bar .active {
		color:#343434;
	}
	.active .swiper-tab-line {
		border-bottom:6upx solid #FEDE33;
		width:70upx;
		margin:auto;
		border-top:6upx solid #FEDE33;
		border-radius:20upx;
	}

</style>

• js

export default {
props: {
tabBars: Array,
tabIndex: Number,
scrollStyle: {
type: String,
default: ""
},
scrollItemStyle: {
type: String,
default: ""
}
},
methods: {
tabtap(index) {
//点击tab时把本身的index传给父组件index.vue
this.$emit('tabtap', index);
},
}
}

页面中使用

• 引用组件

<script>import swiperTab from "../../components/swiper-tab/swiper-tab.vue"
export default {
    components:
    {
      swiperTab
    },
    onLoad() {
      uni.getSystemInfo({
        success: (res) = >{
          let height = res.windowHeight - uni.upx2px(100) 
          this.swiperheight = height;
        }
      })
    },
    data() {
      return {
        tabIndex: 0,
        // 选中的
        tabBars: [{
          name: "关注",
          id: "guanzhu"
        },

• css(重点)

<style>
	/* 解决不能滚动问题 */
	/* uni-swiper .uni-swiper-wrapper, */
	uni-swiper-item {
	    overflow-y: scroll !important;
	}
</style>
