uniapp packaged h5 cannot browse the specified page

With the continuous popularity of mobile Internet, application development is also developing in the direction of multi-platform and cross-terminal. In order for applications to run on different platforms, developers need to use some cross-platform development frameworks. One of the more popular frameworks is uniapp.

Uniapp is a cross-platform development framework developed based on vue. It can generate applications for multiple platforms such as mini programs, H5, and App at the same time, greatly improving development efficiency. However, some developers will encounter some problems when using uniapp to package H5, such as H5 being unable to browse the specified page. So, what exactly causes this problem?

First of all, we need to understand the page routing management mechanism of uniapp. In uniapp, jumps between pages are not implemented directly through URLs, but through the routing table defined by uniapp. This routing table defines the path of each page, the method to be executed by the page, and so on. When the application is running, uniapp will dynamically load the corresponding page according to the routing table, thereby realizing jumps between pages.

So, when H5 cannot browse the specified page, it is most likely caused by incorrect routing configuration. For example, when configuring the routing table, developers may overlook some small details, such as path case sensitivity or the direction of path slashes, which may cause routing to not work properly. In addition, there are some extension libraries or components that may affect routing, so we also need to pay attention to these issues.

There are many ways to solve this problem, and different methods are adopted according to different situations. Next, let’s discuss some common solutions:

The first method is to check the routing table configuration of uniapp. If H5 cannot browse the specified page, first check whether the routing table configuration is correct. For example, whether the path is case-sensitive, whether the path ends with a slash, etc. In addition, you can also use the routing jump API provided by uniapp for debugging to see if the page can jump successfully. If the jump is successful, it means that the routing table is configured correctly and the problem is not here.

The second method is to check whether extension libraries or components are used. Some extension libraries or components may affect routing, so we need to check whether these libraries or components are used. If used, you can try to remove these libraries or components for testing to see if the problem can be solved.

The third method is to use Chrome’s debugging tools. The Chrome browser provides a wealth of debugging tools that can help us find the problem. For example, you can view the console output of the web page, network requests, etc. to find the source of the problem. At the same time, Chrome also provides some debugging tools (such as Elements tools) that can help us check HTML, CSS, etc., to find problems.

In short, if you encounter the problem that H5 cannot browse the specified page and still cannot solve it after trying the above methods, you may consider seeking help from the uniapp official or the community. Because the root cause of the problem may be very complex, it needs to be investigated through a variety of methods and tools to find the final solution.
