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.
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.$mount()
Here, we introduce the Vue Router plug-in and assign it to the router
object. Then, when instantiating the Vue application, inject the router
object into the Vue instance, making it available throughout the application.
UniApp provides two methods uni.navigateTo
and uni.redirectTo
to achieve page jump change. uni.navigateTo
is used to jump to a new page and retain the status of the original page, while uni.redirectTo
is used to directly replace the current page.
The following is an example that demonstrates how to use routing for page jumps in UniApp:
// 在A页面中跳转到B页面 uni.navigateTo({ url: '/pages/B' }) // 在B页面中跳转到C页面 uni.navigateTo({ url: '/pages/C' }) // 在C页面中跳转到D页面,并关闭C页面 uni.redirectTo({ url: '/pages/D' })
In this example, we use uni on pages A, B and C respectively. navigateTo
performs page jump and jumps to pages B, C and D respectively. In the C page, we also use the uni.redirectTo
method to close the C page and jump to the D page.
Sometimes, we need to pass parameters between routes. UniApp provides two ways to implement route parameter passing: through query parameters and through params parameters.
Using query parameters, you can add parameters to the url when jumping, as shown below:
uni.navigateTo({ url: '/pages/B?id=1&name=example' })
On the page that receives parameters, you can pass this.$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!
