Detailed explanation of applet jumps: navigateTo and other common jump methods

With the rapid development of WeChat Mini Programs, the jump page has become an important link in the development of Mini Programs. In applets, commonly used jump methods include navigateTo, redirectTo, switchTab, and reLaunchso on. This article will introduce the usage and characteristics of these jump methods in detail.

1. `navigateTo` Method

navigateToIt is one of the most commonly used jumping methods in applets. Its role is to open a new page and preserve the state of the current page. The specific usage is as follows:

wx.navigateTo({
  url: 'pages/detail/detail?id=123',
  success: (res) => {
    console.log('跳转成功');
  },
  fail: (err) => {
    console.error('跳转失败', err);
  }
})

url: The page path to jump to, which can take parameters.
success: The callback function for a successful jump.
fail: Callback function for jump failure.

It should be noted that navigateTothere are restrictions on the jump levels of , and it can only jump to five levels of pages at most.

2. `redirectTo` Method

redirectToSimilar to navigateTo, the difference is that redirectTothe current page is closed and a new page is opened. The usage is as follows:

wx.redirectTo({
  url: 'pages/login/login',
  success: (res) => {
    console.log('跳转成功');
  },
  fail: (err) => {
    console.error('跳转失败', err);
  }
})

After using redirectToto jump, the current page will be destroyed, and you cannot return to this page through the back button.

3. `switchTab` Method

switchTabIt is used to jump to the TabBar page of the applet and close other non-TabBar pages. For example:

wx.switchTab({
  url: 'pages/index/index',
  success: (res) => {
    console.log('跳转成功');
  },
  fail: (err) => {
    console.error('跳转失败', err);
  }
})

It should be noted that switchTabit can only jump to the page with TabBar, and parameters are not allowed.

4. `reLaunch` Method

reLaunchIt is a special jump method, it will close all pages and open a new page. It is often used to restart the applet or jump to the home page of the application. The usage is as follows:

wx.reLaunch({
  url: 'pages/index/index',
  success: (res) => {
    console.log('跳转成功');
  },
  fail: (err) => {
    console.error('跳转失败', err);
  }
})

5. Other jumping methods

In addition to the several jump methods introduced above, the applet also provides some other jump methods, including navigateBack, , navigateToMiniProgramand so on. Select an appropriate jump mode based on actual needs.

Summarize

This article introduces the commonly used jumping methods in applets in detail, including navigateTo, redirectTo, switchTab, reLaunchand so on. Understanding the characteristics and usage of these jump methods can better perform the jump operation between Mini Program pages and improve user experience. During the development process, choose the appropriate redirection method according to specific needs, and pay attention to handling the redirection failure, so as to ensure that users can browse and use the applet normally.
