Does the page that uniapp jumps to need to be configured?

With the development of mobile Internet, more and more people have begun to develop mobile applications. One of the most commonly used cross-platform development frameworks is uniapp. However, many developers have a question when using uniapp: Do the jump pages need to be configured? This article will introduce in detail the configuration issues related to the uniapp jump page.

First of all, you need to understand what uniapp is and its jump mechanism.

uniapp is a cross-platform application development framework developed based on Vue.js. It uses a development method called "plug-in-based architecture" (plug-in development), which can simultaneously transform the same code into applications on multiple platforms such as WeChat mini-programs, Alipay mini-programs, H5, and App.

In uniapp, page jumps are divided into two situations: intra-page jumps and cross-page jumps.

Intra-page jumps are usually implemented using Vue.js routing, and jumps between pages can be achieved through routing files.

For example, the routing in the following code defines two pages, namely "/index" and "/detail", and can be jumped through routing in the page.

const routes = [
  {
    path: '/index',
    component: Index
  },
  {
    path: '/detail',
    component: Detail
  },
]

Cross-page jumps are usually implemented using the API provided by uniapp. It includes the following three methods:

• realize page jump through navigateTo;
• realize page redirection through redirectTo;
• realize bottom tab switching through switchTab.

Now back to the question: Does the jump page need to be configured?

For intra-page jumps, you only need to define the page path in the routing file to achieve jumps between pages. No other special configuration is required. However, for cross-page jumps, the following two aspects of configuration are required.

1. Configure page path

In uniapp, each page needs to be defined through the Page() function. The path path of the page can be set in the configuration item of this function, for example:

export default {
  // 定义页面路径
  path: '/detail',
  data() {
    return {
      ...
    }
  }
  ...
}

At this time, the page jump can be realized through the API, for example:

uni.navigateTo({
  url: '/pages/detail/detail'
})

It should be noted that the path must Written in the form of /pages/detail/detail, where "/pages" is a fixed path prefix.

2. Configuring the manifest.json file

In addition to setting the path in the page, configuration is also required in the manifest.json file.

Manifest.json is the configuration file of the uniapp project, which is used to specify the global configuration of the application, including page path, App icon, startup page, etc. In this file, you can set the "pages" array to configure all page paths:

{
  "pages": [
    {
      "path": "pages/index/index",
      "style": {}
    },
    {
      "path": "pages/detail/detail",
      "style": {}
    }
  ],
  ...
}

It should be noted that when configuring pages, it also needs to be written in the form of /pages/index/index.

To summarize, the page that uniapp jumps to requires path configuration and manifest.json file configuration. Through these two steps, you can jump and navigate between pages.

In addition, it should be noted that the uniapp page path and manifest.json file configuration are very important. You must check carefully to ensure that all paths are correct. Otherwise, there will be a situation where the jump cannot be made.

In general, uniapp is a very convenient and efficient cross-platform application development framework. Whether you are jumping within a page or across pages, you need to configure the path and carefully check the manifest.json file configuration. Only in this way can the normal operation of the application be guaranteed.
