How to use Vue for multi-terminal adaptation and responsive design

In the mobile Internet era, we must not only pay attention to the adaptation of web pages on different screen sizes, but also consider the adaptability of various mobile devices and platforms. compatibility. As a popular front-end framework, Vue provides many convenient tools and technologies that can help developers achieve multi-terminal adaptation and responsive design. This article will introduce how to use Vue for multi-terminal adaptation and responsive design, and provide code examples.

1. Use flexible.js for mobile adaptation

On mobile devices, different screen resolutions and pixel densities will lead to differences in page display effects. In order to achieve mobile adaptation, we can use the flexible.js library to dynamically adjust the size of page elements according to the pixel ratio of the device. The specific steps are as follows:

(1) Introduce the flexible.js library into the project. You can install it through npm or download the library file directly.

(2) Introduce the flexible.js library into the entry file main.js.

import 'flexible.js';

(3) Use rem as the unit in the project to set the size of page elements. flexible.js will dynamically calculate the pixel value corresponding to the rem unit based on the viewport width and device pixel ratio.

.container {
  width: 10rem;
  height: 5rem;
}

After the above steps are completed, the size of the page elements will be adapted according to the pixel ratio of the device, thereby achieving mobile adaptation.

2. Responsive design using Vue

Vue provides the capability of responsive design, which can automatically update the status of the page according to different devices and user operations. Developers can use Vue’s computed properties and listeners to implement responsive designs. The specific steps are as follows:

(1) Declare the data that needs to be responded to in the Vue instance.

data() {
  return {
    screenWidth: 0
  }
}

(2) In the created life cycle of Vue, use the window size event to update the value of the screen width.

created() {
  window.addEventListener('resize', this.handleResize);
  this.handleResize();
},
methods: {
  handleResize() {
    this.screenWidth = window.innerWidth;
  }
}

(3) Use calculated properties to dynamically calculate the content to be displayed based on the screen width.

computed: {
  showContent() {
    return this.screenWidth <= 768 ? '移动端展示内容' : 'PC端展示内容';
  }
}

After the above steps are completed, the page will automatically update the display content according to the screen width, realizing responsive design.

The comprehensive example code is as follows:

The above code example demonstrates how to use Vue for multi-terminal adaptation and responsive design. Mobile adaptation can be achieved using the flexible.js library, and the responsive design of Vue can automatically update the status of the page according to different devices and user operations. The combination of these technologies can help us better adapt to different devices and platforms and provide a better user experience.
