A brief analysis of how UniApp jumps to other pages

UniApp is a development tool based on the Vue.js framework launched by DCloud. It can achieve the effect of writing once and running on multiple terminals. Developers can use UniApp to quickly build a cross-platform application. During the UniApp development process, it is often necessary to jump between pages. This article will introduce how to jump to other pages in UniApp.

1. Jump using the name of the page

In UniApp, you can jump by using the name of the page. Suppose we have a page named home, you can use the following code to jump from the current page to the home page:

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

Among them, the uni.navigateTo() method is used. In the url parameter, you need to specify the path of the page to be jumped, starting with /pages/, followed by the path of the page. It can be found that the name of the page is actually specified directly.

2. Jump using parameters

In addition to directly specifying the page name to jump, you can also jump with parameters. Suppose we want to jump to a page named detail and need to pass an id parameter, we can use the following code to achieve this:

uni.navigateTo({
  url: '/pages/detail/detail?id=123'
});

In the url parameter, the form of ?id=123 is used to pass it parameter. In the detail page, you can get the passed parameter value by getting the query parameter:

export default {
  onLoad(options) {
    const id = options.id;
    // 其他逻辑代码
  }
}

Use options.id to get the passed id parameter value.

3. Use uni-app’s built-in page routing component to jump

Uni-App provides a built-in page routing component to facilitate page jump processing. We can use the uni-navigation component, which can achieve the following functions:

• can jump to a new page according to the URL;
• can switch pages when the URL changes;
• Can handle the browser's forward and back buttons so that users can use our application just like a regular browser.

The usage method is as follows:

<uni-navigation>
  <uni-nav-bar></uni-nav-bar>
  <uni-tab-bar></uni-tab-bar>
  <uni-page-view>
    <!-- 这里放置页面内容 -->
  </uni-page-view>
</uni-navigation>

In this way, the content of the page can be completely displayed, and it also has the function of routing component.

4. Use the built-in jump method of uni-app

Uni-App also provides other built-in jump methods, such as uni.switchTab(), uni.reLaunch() , uni.navigateBack(), etc. These methods will be more practical in specific business scenarios and can be used as needed.

Summary:

The above is how UniApp jumps to other pages. I believe that through the introduction of this article, everyone has a deeper understanding of UniApp's jump method. In actual development, different business scenarios require different jump methods. Therefore, developers must flexibly use these jump methods according to the actual situation to achieve a good application experience.
