What should I do if uniapp does not allow left and right swiping?

As a front-end developer, we often use various frameworks and libraries to speed up our development process. UniApp is a cross-platform development framework based on Vue.js and WeChat mini-programs. It can build applications for multiple platforms such as mini-programs, H5, App, and WeChat public accounts at the same time. In UniApp, we can use component libraries and some APIs to implement various functions. However, sometimes we may encounter some problems, such as the problem of not allowing left and right sliding in UniApp. So, how to solve this problem?

First of all, we need to understand why left and right sliding is not allowed in UniApp. This is because UniApp uses the uni-app-plus framework, which prohibits left and right sliding behavior on all pages by default. This is to avoid horizontal sliding of the page, thereby improving the user experience of the page. But in some cases we need to achieve the effect of left and right sliding, such as carousel images, left and right sliding lists, etc. So, how to implement these functions?

One solution is to use the swiper component. The swiper component is a carousel component provided by UniApp, which can achieve effects such as carousel and sliding switching. We only need to introduce the swiper component into the page and configure it according to the document requirements. For example, the following is a simple swiper component configuration:

<template>
  <view>
    <swiper autoplay="true" interval="3000">
      <swiper-item>
        <image src="/static/image/1.jpg"></image>
      </swiper-item>
      <swiper-item>
        <image src="/static/image/2.jpg"></image>
      </swiper-item>
      <swiper-item>
        <image src="/static/image/3.jpg"></image>
      </swiper-item>
    </swiper>
  </view>
</template>

In the above code, we first introduced the swiper component, then created a swiper component in the page and added three swiper-items to it . Each swiper-item contains a picture. These pictures will achieve a carousel effect in the swiper component and automatically switch every 3 seconds.

In addition to the swiper component, we can also use the scroll-view component to achieve the left and right sliding effect. The scroll-view component can scroll and display a group of sub-elements, and supports effects such as up and down, left and right sliding. We can introduce the scroll-view component into the page and configure it according to the document requirements. For example, the following is a simple scroll-view configuration:

<template>
  <scroll-view scroll-x="true">
    <view class="item">item1</view>
    <view class="item">item2</view>
    <view class="item">item3</view>
  </scroll-view>
</template>

<style>
  .item {
    width: 300rpx;
    height: 200rpx;
    background-color: #eee;
    margin-right: 20rpx;
    display: inline-block;
  }
</style>

In the above code, we created a scroll-view component and set the scroll-x attribute to true, indicating that the component supports left and right sliding. In the scroll-view component, we created three view elements, which will achieve the effect of sliding left and right in the scroll-view component. At the same time, we set styles for each view element so that they appear like a list.

Finally, another solution is to achieve the left and right sliding effect through custom components. We can create a custom component and implement the logic of left and right sliding in it. This method is relatively complicated and requires certain experience in Vue.js and WeChat applet development, but it can flexibly achieve various left and right sliding effects.

To summarize, UniApp does not allow left and right sliding by default, but we can still use swiper components, scroll-view components, custom components and other methods to achieve the effect of left and right sliding. In the actual development process, we need to choose the appropriate method according to specific needs, and configure and use it in accordance with the document requirements. I hope that this article can help everyone better understand the problem of left and right sliding in UniApp and solve related problems that may be encountered during the development process.
