How to solve the problem that the uniapp soft keyboard does not close automatically

With the development of mobile Internet, the use of frameworks and tools to quickly develop APPs has become mainstream. As a cross-platform development framework, uniapp plays an irreplaceable role in development. It can support multiple platforms and has convenience It has the advantages of fast speed and high code reuse rate. In uniapp development, the use of soft keyboard is very common. However, sometimes developers will encounter the problem that the soft keyboard does not close automatically, which will lead to a poor user experience when using the APP. This article will introduce how to solve the problem of uniapp The soft keyboard does not close automatically.

The soft keyboard does not close automatically There can be many reasons, and we can analyze it from the following aspects:

① Compatibility issues between keyboard and input box.

In some cases, the keyboard is not compatible with the input box, causing the keyboard to fail to close automatically.

② Software version problem.

Different software versions may have compatibility issues, in which the soft keyboard may not close automatically.

③ Code problem.

The code implementation is incorrect, resulting in the inability to close the soft keyboard.

2. Solution effect

Using the blur() or focus() method can solve the problem of the soft keyboard not automatically closing, but in some cases, the user needs to manually The operation is not intelligent enough. The use of special plug-ins can effectively solve the problem of the soft keyboard not automatically closing, and more situations have been taken into account when using it, which can better improve the user experience.

4. Summary

Not automatically closing the soft keyboard is one of the common problems in mobile APP development. For users, the operating experience in this case is not good. In uniapp, we can solve this problem by calling the blur() or focus() method, or we can use a special plug-in to solve this problem. To improve the user experience of mobile APP, the normal use of soft keyboard is indispensable. We need to constantly find solutions to make APP more humane and friendly, so as to better meet the needs of users.
