How does uniapp implement the function of jumping to the second-level page?

Uni-app is a cross-end development framework, and it is very popular. Using the Uni-app development project, you can localize, compile and package the developed applications on multiple platforms (such as Android, Apple, and web pages) to achieve cross-platform operation. For example, you can jump to a sub-second page in Uni-app.

Regarding jumping to sub-secondary pages, we need to understand several concepts. First, we need to clarify what a page is. In Uni-app, page refers to switching between views, and each view is a separate page. At the same time, you need to know that routing in Uni-app is very important.

Therefore, when Uni-app jumps to the sub-secondary page, we need to use route jump. We can use Vue Router's $route to jump on the current page:

router.push({ path: '/child1/grandchild1' })

This statement jumps through push Go to the second-level sub-page. "/child1/grandchild1" here refers to the path of the second-level child page. It should be noted that the path here should be a complete path, not a relative path. So, you should use "/" as the root of the path.

In addition, it should be noted that in Uni-app, due to differences between different platforms, the routing methods are not exactly the same. For example, if you want to jump to a second-level child page on the Web, the statement can be written as:

this.$router.push({ path: '/child1/grandchild1' })

It should be noted that programmatic navigation can also be used to jump to sub-secondary pages in Uni-app. The way to introduce routes is the same as above:

import router from '@/router'

Then, you can use programmatic navigation to jump to the sub-secondary page:

router.push('/child1/grandchild1')

Of course, in addition to using routing jumps, depending on the business, you may need to use some other methods, such as passing parameters. In general, jumping to sub-secondary pages is a basic function of Uni-app development. Mastering the jumping method can facilitate development and improve work efficiency.
