<view>

<view class='main-title'>资讯</view>  

<scroll-view class="scroll-horizontal" scroll-x="true" wx:for="{{newTitles}}" wx:key="item">

<view id='{{item.colid}}' class='nav-item'>{{item.colname}}</view>

</scroll-view>

</view>

.scroll-horizontal{

width: 100%;

height: 40px;

white-space: nowrap;

}

.nav-item{

width: 100px;

height: 40px;

line-height: 30px;

text-align: center;

display: inline-block;

background-color: #E2FCFE;

}

//index.js

//获取应用实例

const app = getApp()

Page({

data: {

newTitles: [{ colname: 'xx', colid: 1 }, { colname: 'tt', colid: 2 }, { colname: 'gg', colid: 3 }]

}

})

为什么scroll-x无效，按官网文档上不加属性值true也试过，是无效的

<scroll-view class="scroll-horizontal" scroll-x wx:for="{{newTitles}}" wx:key="item">

<view id='{{item.colid}}' class='nav-item'>{{item.colname}}</view>

</scroll-view>
