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.valuethis.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},
