Use WeChat applet to achieve text scrolling effect

As an emerging application development method, applet has the characteristics of rapid development, cross-platform and user-friendliness. It has been Becoming the first choice of more and more developers. In WeChat mini programs, achieving text scrolling effects is a common requirement. This article will introduce how to use WeChat mini programs to achieve text scrolling effects through specific code examples.

1. Create a new WeChat applet project

First, we need to create a new WeChat applet project. In the WeChat Developer Tools, select New Project, fill in the project name, AppID and other relevant information, and then click OK to create the project.

2. Write page layout code

After creating the project, we need to write the page layout code. Open the pages/index/index.wxml file in the project and add the following code to the file:

<view class="scroll-container">
   <view class="scroll-content">
      <view class="scroll-item">{{scrollText}}</view>
   </view>
</view>

The above code defines a file named scroll-container Container, which contains a content container named scroll-content, and a scroll text named scroll-item.

3. Write style code

In the pages/index/index.wxss file, add the following code to define the style of the page:

.scroll-container {
   width: 100%;
   height: 100%;
   overflow: hidden;
}

.scroll-content {
   white-space: nowrap;
   animation: scroll 5s linear infinite;
}

.scroll-item {
   display: inline-block;
   font-size: 40rpx;
   color: #000000;
   padding-right: 10rpx;
   padding-left: 10rpx;
   animation: text-animation 5s linear infinite;
}

@keyframes scroll {
   0% {
      transform: translateX(0);
   }
   100% {
      transform: translateX(-100%);
   }
}

@keyframes text-animation {
   0% {
      opacity: 0;
   }
   20% {
      opacity: 1;
   }
   80% {
         opacity: 1;
     }
   100% {
         opacity: 0;
     }
}

The above code defines scroll-containerThe width of the container is 100%, the height is 100%, and the excess part is set to be hidden. scroll-contentThe container is set to white-space: nowrap; so that the text does not wrap, and an animation named scroll is used to achieve the scrolling effect. scroll-item defines the style of scrolling text and uses an animation named text-animation to achieve the fade-in and fade-out effect.

4. Write logic code

In the pages/index/index.js file, add the following code to achieve the logic of the text scrolling effect:

Page({
  data: {
    scrollText: '这是一个文字滚动效果的小程序示例，可以根据实际需求自定义滚动文字内容。',
  },
})

A scrollText variable is set in the above code to store the content of the scrolling text.

5. Build and preview the mini program

After completing the above code writing, click the build button in the WeChat developer tools to get the preview QR code of the mini program, and use WeChat on your mobile phone Scan the preview QR code to see the text scrolling effect of the mini program.

Summary:

Through the above steps, we successfully implemented a WeChat applet with text scrolling effect. By setting the width of the container, defining animations, and using related styles, we can easily achieve the text scrolling effect. Of course, the above example is just a simple implementation, and developers can customize it according to actual needs, such as changing text color, font size, scrolling speed, etc.

As a rapid development and user-friendly application development method, WeChat applet provides developers with rich interfaces and styles, helping developers to quickly implement various application functions. I hope this article can help everyone understand and master the text scrolling effect of WeChat applet.
