最近正在用uniapp框架做微信小程序,遇到一个需求,分类浏览数据。于是,我打算用uni-segmented-control加swiper联动来实现,首先上代码:
<template>
<view class="page-box">
<uni-segmented-control style="margin-left: 15rpx;margin-right: 15rpx;margin-top:15rpx;" :current="tabIndex" :values="items"
@clickItem="onClickItem" styleType="button" activeColor="#007aff"></uni-segmented-control>
<swiper :current="tabIndex" style="margin: 15rpx;" class="content-box" :duration="300" @change="ontabchange">
<swiper-item>
<view>我是第一个内容页</view>
</swiper-item>
<swiper-item>
<view>我是第二个内容页</view>
</swiper-item>
<swiper-item>
<view>我是第三个内容页</view>
</swiper-item>
</swiper>
</view>
</template>
<script>
export default {
data() {
return {
WORKERID:'',
baseurl:'',
datalist:[],
tabIndex:0,
datalist2:[],
//items:['装配补加','mpm补加','其他补加','其他补加1','其他补加2','其他补加3','其他补加4','其他补加5'],
items:['装配补加','mpm补加','其他补加'],
datalist3:[]
}
},
onLoad() {
this.baseurl=getApp().globalData.baseurl;
this.WORKERID=uni.getStorageSync("WORKERID");
},
onShow() {
this.shuaxin();
},
methods: {
onClickItem(e){
this.tabIndex = e.currentIndex;
},
ontabchange(e){
this.tabIndex = e.target.current;
},
}
}
</script>
<style>
page {
width: 100%;
height: 100%;
}
.page-box {
display: flex;
flex-direction: column;
height: 100%;
}
.head-box {
flex-shrink: 0; //保持内容不缩放,适用于内容不确定大小时候
// height:100rpx; //设置高度为100,如果内容确定为这么高的话
}
.flexbox {
display: flex;
flex-direction: column;
height: 100%;
}
.content-box {
flex-grow: 1; //充满屏幕
height: 100%; //如果中间不充满屏幕的话,自适应,底部会跟随在中间布局后面
overflow: auto;
}
.footer-box {
flex-shrink: 0; //保持内容不缩放,适用于内容不确定大小时候
// height:100rpx; //设置高度为100,如果内容确定为这么高的话
}
.scroll-Y {
flex-grow: 1; //充满屏幕
height: 100vh; //如果中间不充满屏幕的话,自适应,底部会跟随在中间布局后面
overflow: auto;
}
.line-h {
height: 3rpx;
background-color: #cccccc;
}
</style>
但是当我的items中的选项多的时候,页面就会变得很难看,所有的元素都会挤在一起,于是我就想在uni-segmented-control的外面套个scroll-view,uni-segmented-control加个style=“width:1000rpx”,但是不好使,还是那个样子。没办法,我只好动uni-segmented-control的源码了,首先咱先看看uni-segmented-control的源码
<template>
<view :class="[styleType === 'text'?'segmented-control--text' : 'segmented-control--button' ]"
:style="{ borderColor: styleType === 'text' ? '' : activeColor }" class="segmented-control">
<view v-for="(item, index) in values" :class="[ styleType === 'text' ? '': 'segmented-control__item--button',
index === currentIndex&&styleType === 'button' ? 'segmented-control__item--button--active': '',
index === 0&&styleType === 'button' ? 'segmented-control__item--button--first': '',
index === values.length - 1&&styleType === 'button' ? 'segmented-control__item--button--last': '' ]" :key="index"
:style="{ backgroundColor: index === currentIndex && styleType === 'button' ? activeColor : '',borderColor: index === currentIndex&&styleType === 'text'||styleType === 'button'?activeColor:'transparent' }"
class="segmented-control__item" @click="_onClick(index)">
<view>
<text :style="{color:
index === currentIndex
? styleType === 'text'
? activeColor
: '#fff'
: styleType === 'text'
? '#000'
: activeColor}" class="segmented-control__text" :class="styleType === 'text' && index === currentIndex ? 'segmented-control__item--text': ''">{{ item }}</text>
</view>
</view>
</view>
</template>
<script>

我的处理方法比较简陋,就是在原组件的样式里加个宽度,然后外面加个scrollview,时间不多,就先这么对付着。大佬们可以把宽度做成组件的属性。
<scroll-view scroll-x="true">
<uni-segmented-control style="margin-left: 15rpx;margin-right: 15rpx;margin-top:15rpx;" :current="tabIndex" :values="items"
@clickItem="onClickItem" styleType="button" activeColor="#007aff"></uni-segmented-control>
</scroll-view>
