导文

unaipp自带的标签页和ui设计相差太大，直接修改组件比手写一个还麻烦，下面手写一个。

样式

先用scroll-view做一个滑动，不然多的话滑动不了。

	<scroll-view class="scroll-view_H" scroll-x="true" @scroll="scroll" scroll-left="120">
				<span class="checkDetails-nav-item action">
					体重
				</span>
				<span class="checkDetails-nav-item">
					餐食
				</span>
				<span class="checkDetails-nav-item">
					喝水
				</span>
				<span class="checkDetails-nav-item">
					睡眠
				</span>
				<span class="checkDetails-nav-item">
					运动
				</span>
			</scroll-view>

然后实现默认样式，和标签页点击样式。

.scroll-view_H {
			white-space: nowrap;
			width: 100%;
			background: #fff;
		}

		.scroll-view-item {
			height: 300rpx;
			line-height: 300rpx;
			text-align: center;
			font-size: 36rpx;
		}

		.scroll-view-item_H {
			display: inline-block;
			width: 100%;
			height: 300rpx;
			line-height: 300rpx;
			text-align: center;
			font-size: 36rpx;
		}

		.checkDetails-nav-item {
			font-size: 16px;
			font-weight: 500;
			letter-spacing: 0px;
			line-height: 30px;
			color: rgba(75, 89, 105, 1);
			text-align: left;
			vertical-align: top;
			background: #fff;
			padding: 0px 30px;

		}

		.action {
			font-size: 18px;
			font-weight: 700;
			letter-spacing: 0px;
			line-height: 25.2px;
			color: rgba(12, 16, 25, 1);
			position: relative;
		}

		.action::after {
			content: '';
			position: absolute;
			background-image: url(../../static/checkDetails/action.png);
			background-size: 100%;
			background-repeat: no-repeat;
			width: 28px;
			height: 10px;
			top: 18px;
			left: 34px;
		}

改成动态列表

循环自定义的teb组件就好

		<scroll-view class="scroll-view_H" scroll-x="true" @scroll="scroll" scroll-left="120">
				<span v-for="(item, index) in navList" :key="index" class="checkDetails-nav-item" :class="{ 'action': navCurrent == item.value }">
					{{ item.text }}
				</span>
			</scroll-view>

在data中定义列表，和当前展示的页面值

	data() {
		return {
			navCurrent: 'weight',
			navList: [{
				text: '体重',
				value: 'weight'
			}, {
				text: '餐食',
				value: 'food'
			}, {
				text: '喝水',
				value: 'drink'
			}, {
				text: '睡眠',
				value: 'sleep'
			}, {
				text: '运动',
				value: 'sport'
			}],
		}
	},

加上切换页面效果。

切换点击效果

加上一个handleSwitch点击事件

<span v-for="(item, index) in navList" :key="index" class="checkDetails-nav-item"
					:class="{ 'action': navCurrent == item.value }" @click="handleSwitch(item)">
					{{ item.text }}
				</span>

切换navCurrent 值就好

handleSwitch(item){
			this.navCurrent = item.value
		}

加上点击自动滑动scroll-view

先把scroll-left改成动态的，在handleSwitch方法中添加index索引值传过去

<scroll-view class="scroll-view_H" scroll-x="true" :scroll-left="scrollValue">
				<span v-for="(item, index) in navList" :key="index" class="checkDetails-nav-item"
					:class="{ 'action': navCurrent == item.value }" @click="handleSwitch(item, index)">
					{{ item.text }}
				</span>
			</scroll-view>

使用index索引值，判断滑动位置

handleSwitch(item,index) {
			this.navCurrent = item.value
			this.scrollValue = index * 100
		}

加上切换组件效果

先创建好组件，一般放在components里面

在父页面中引入组件，在template里面写组件

	<view class="checkDetails">
		<view class="checkDetails-nav">
			<scroll-view class="scroll-view_H" scroll-x="true" :scroll-left="scrollValue">
				<span v-for="(item, index) in navList" :key="index" class="checkDetails-nav-item"
					:class="{ 'action': navCurrent == item.value }" @click="handleSwitch(item, index)">
					{{ item.text }}
				</span>
			</scroll-view>
		</view>
		<drinkPage v-if="navCurrent == 'drink'"></drinkPage>
		<foodPage v-if="navCurrent == 'food'"></foodPage>
		<sleepPage v-if="navCurrent == 'sleep'"></sleepPage>
		<sportPage v-if="navCurrent == 'sport'"></sportPage>
		<weightPage v-if="navCurrent == 'weight'"></weightPage>

	</view>
</template>

<script>

别忘了用import 引入和components注册组件名哦

import drinkPage from './components/drinkPage/index.vue'
import foodPage from './components/foodPage/index.vue'
import sleepPage from './components/sleepPage/index.vue'
import sportPage from './components/sportPage/index.vue'
import weightPage from './components/weightPage/index.vue'

export default {
	components: {
		drinkPage,
		foodPage,
		sleepPage,
		sportPage,
		weightPage
	},
