UniApp's tips for implementing route management and page jumps

UniApp shares tips on implementing routing management and page jumps

UniApp is a cross-platform development framework based on Vue.js, which can be used to develop applications for multiple platforms such as iOS, Android and Web. . In UniApp, route management and page jump are very important parts. This article will share some UniApp tips for implementing route management and page jump, and provide code examples for reference.

1. Routing Management

UniApp uses Vue Router to manage routing and provides some common APIs for routing configuration and operation. Before starting to use routing, you need to install and introduce the Vue Router plug-in. In the main.js file, you can configure it like this:

import Vue from 'vue'
import App from './App'
import router from './router'

Vue.config.productionTip = false

App.mpType = 'app'

const app = new Vue({
  ...App,
  router
})
app.$mount()

Here, we introduce the Vue Router plug-in and assign it to the router object. Then, when instantiating the Vue application, inject the router object into the Vue instance, making it available throughout the application.

2. Page jump

UniApp provides two methods uni.navigateTo and uni.redirectTo to achieve page jump change. uni.navigateTo is used to jump to a new page and retain the status of the original page, while uni.redirectTo is used to directly replace the current page.

The following is an example that demonstrates how to use routing for page jumps in UniApp:

// 在A页面中跳转到B页面
uni.navigateTo({
  url: '/pages/B'
})

// 在B页面中跳转到C页面
uni.navigateTo({
  url: '/pages/C'
})

// 在C页面中跳转到D页面，并关闭C页面
uni.redirectTo({
  url: '/pages/D'
})

In this example, we use uni on pages A, B and C respectively. navigateTo performs page jump and jumps to pages B, C and D respectively. In the C page, we also use the uni.redirectTo method to close the C page and jump to the D page.

3. Route parameter passing

Sometimes, we need to pass parameters between routes. UniApp provides two ways to implement route parameter passing: through query parameters and through params parameters.

Using query parameters, you can add parameters to the url when jumping, as shown below:

uni.navigateTo({
  url: '/pages/B?id=1&name=example'
})

On the page that receives parameters, you can pass this.$route. query to get the parameter value, as shown below:

export default {
  mounted() {
    console.log(this.$route.query.id) // 输出1
    console.log(this.$route.query.name) // 输出example
  }
}

To use the params parameter, you need to define the parameter name in the routing configuration, as shown below:

// 在路由配置中定义参数名
{
  path: '/pages/B/:id/:name',
  name: 'B',
  component: B
}

Then, you can pass uni.navigateTo method to pass parameters, as shown below:

uni.navigateTo({
  url: '/pages/B/1/example'
})

On the page receiving parameters, you can get the parameter value through this.$route.params, as follows Display:

export default {
  mounted() {
    console.log(this.$route.params.id) // 输出1
    console.log(this.$route.params.name) // 输出example
  }
}

Through the above examples, we can see the basic operations of routing management and page jump in UniApp. Through the API provided by the Vue Router plug-in, we can easily configure and operate routing, and implement page jumps through the uni.navigateTo and uni.redirectTo methods. At the same time, UniApp also provides a way to pass parameters. You can choose to use query parameters or params parameters to pass parameters as needed.

I hope this article can help everyone better understand and use the routing management and page jump functions in UniApp. If you have other questions about UniApp, you can check UniApp official documentation or refer to other relevant materials. I wish you all good results in UniApp development!
