Can UL still be used in UniApp?

UniApp is a cross-platform development framework. Developers can use a set of codes to develop applications for multiple platforms such as WeChat mini-programs, Alipay mini-programs, H5, and App. UniApp provides many components to develop applications conveniently and quickly, among which the UL component is a commonly used list component.

However, recently some developers have discovered that when using UL components, warning prompts will appear in some small programs. This has aroused everyone's doubts: Can UL in UniApp still be used?

UL component

The UL component is a list component in the UniApp framework, used to present data in the form of a list. Display data through scrolling, supporting functions such as adding headers, bottoms, scrolling loading, pull-down refresh, etc. The use of the UL component is very simple. You only need to pass in the data array and rendering function to render the list. The more common list components include uni-list and uni-grid.

Problem

When using UL components, the following warning prompt will appear in some small programs:

Unknown custom element:

- did you register the component correctly? For recursive components, make sure to provide the "name" option.

This is because in the applet, UL components are not supported and have not been registered. If UL components are used in the page, the mini program will prompt this warning.

Solution

Now that there is a problem that UL components cannot be used, how to solve it?

1. Replace with other components

According to the documentation, UL components can be replaced with uni-list or uni-grid components. Both components are list components in the UniApp framework, similar to UL. Therefore, UL components can be directly replaced with uni-list or uni-grid components to achieve the same effect.

2. Custom components

In addition to choosing ready-made components to replace UL, developers can build a UL component by themselves. The steps to customize components are as follows:

1) Create a directory named ul, and create the index.vue file in the directory.

2) Write the code of the UL component in the index.vue file.

3) Introduce the ul component into the page that needs to use the UL component and use it.

Finally, it should be noted that the above two solutions can be used at the same time. If you need to use the same list component on multiple platforms, you can customize a UL component and encapsulate the uni-list or uni-grid component into the custom UL component. This allows the same component to be used on multiple platforms.

Summary

In the UniApp framework, when using UL components, warning prompts will appear in some small programs. The solution can be to replace the UL component with a uni-list or uni-grid component, or it can be solved by customizing the component. Developers can choose appropriate solutions based on actual needs.
