How to solve uniapp page jump failure

Uniapp is a cross-platform application development framework developed based on the Vue.js framework. It can realize the function of developing Apps and small programs at the same time, and can basically adapt to all mobile devices through a set of codes. In practical applications, we often encounter the problem of uniapp page jump failure. This article will elaborate on this problem.

1. Problem Overview

In uniapp development, page jump is a very common operation. However, sometimes in actual applications we find that after clicking a button or hyperlink, the page does not jump, but stays on the current page, that is, the page jump fails.

2. Problem Troubleshooting

In order to check the reason why the page jump fails, we can follow the following steps:

1. Check whether the jump path in the code is correct. .

2. Check whether any jump function is disabled or conflicts. For example, in some pages created by uni-app, there may be multiple routers, so $Router.xxx needs to be used to jump.

3. Check whether the jump components and events are used correctly. For example, there are multiple jump methods in uni-app. Sometimes we need to use the uni.navigateTo() function to achieve page jump. However, if the uni.switchTab() function is used in the component click event, the page jumps. Transfer invalidated.

4. Check whether the stack of the current page exists. For example, when using the uni.navigateBack() function to return to the previous page, if the previous page does not exist in the stack, the jump fails.

5. Check whether the application has been initialized. If the page jump is performed when the application has not completed initialization, the page jump will fail.

6. Check whether the application’s permissions are disabled. In some cases, application permissions may be disabled. For example, page jumps are not allowed in WeChat applet debugging mode.

3. Solutions

For the above reasons that may cause the page jump to fail, we can adopt the following solutions:

1. Check whether the jump path is correct. , and maintain path consistency.

2. Make sure there is only one router in the application. If you need to use multiple routers, you need to use $Router.xxx to jump.

3. In the component click event, use the correct jump function.

4. Make sure the return page exists in the stack.

5. Make sure the application has been initialized before jumping to the page.

6. Check whether the application’s permissions are disabled.

In addition to the above solutions, we can also use the following techniques to avoid the problem of page jump failure:

1. Try to use the $Router.xxx function instead of the uni.xxx function to page Jump.

2. Before jumping to the page, first determine whether the page has been initialized.

3. During the development process, keep the code concise and comment the code clearly.

4. Summary

In the uniapp development process, page jump is a very common operation. However, when encountering the problem of page jump failure, we need to first investigate the cause of the problem and then take corresponding solutions. Only in this way can we develop high-quality applications and increase their popularity among users.
