How to solve the problem that the page in uniapp keeps refreshing

In Uniapp development, it is a common situation that the page keeps refreshing, which can easily cause poor user experience and affect the use of the application. So, how do we solve this problem?

The author will explain from the following aspects to help you solve the problem of page refreshing in uniapp.

1. Debugging Tool

When the page keeps refreshing, we can first use the debugging tool to troubleshoot the code. Open the "Network" tab in the browser console to view the status of network requests and check whether there are continuous network requests being sent.

If there are network requests that are constantly being sent, you can check the URL of the request to determine which request is being sent continuously and troubleshoot.

At the same time, you can also check whether there is an error message output on the "Console" tab of the console to find the problem.

2. Data request

In uniapp development, asynchronous request for data is a common operation. When the obtained data is not displayed as expected, it may cause the page to be constantly refreshed.

We can use "console.log" to output data when requesting data to see whether the data meets expectations. If the data is incorrect, you can troubleshoot the problem by checking the code of the data interface or the correctness of the backend server data.

You can also use the life cycle function of Vue.js to render the page after the data request is completed to avoid page refresh caused by asynchronous loading of data.

3. Function call

When the function is continuously called, it will also cause the page to be constantly refreshed. Therefore, we need to find which function is called repeatedly and optimize accordingly.

You can use the Vue.js developer tool plug-in to view the function call stack and determine which function is called repeatedly.

At the same time, you can also add some restrictions in the code to control the call of the function, such as setting a variable to determine whether the function has been called.

4. Script introduction

When multiple script files are introduced, there may be conflicts between the script files, causing the page to be constantly refreshed. Therefore, we need to check whether there are any problems with the script introduction and make adjustments accordingly.

You can use debugging tools to check whether there are interdependencies between imported script files, and check whether there are conflicts in imported script files.

In addition, before the page is rendered, the script loading can be placed before other resource files to avoid page refresh due to incomplete loading of the script file.

To sum up, the problem of page refreshing in uniapp can be checked and troubleshooted from the aspects of debugging tools, data requests, function calls and script introduction. By properly adjusting the code, we can effectively solve this problem and improve the application experience.
