How to create elements in uniapp

UniApp is a cross-platform application development framework that supports development once but can run on multiple platforms (H5, iOS, Android, etc.). In UniApp, creating elements is to use components or tags in templates. This article will introduce how to create elements in UniApp.

1. Basic concepts

In UniApp, elements refer to components or labels used to build interfaces. A component is a reusable UI unit encapsulated by UniApp. Compared with labels, it is more powerful and flexible.

2. Method of creating elements

1. Use components

①Built-in components

UniApp provides many built-in components, such as buttons, input boxes, icons and more. Developers only need to use these components in templates to create corresponding elements, such as:

Here, , are the built-in components of UniApp. You can create corresponding elements by using them in the template.

In addition to these basic components, UniApp also provides a wealth of extension components and plug-ins to meet the different needs of developers.

②Custom components

If the built-in components cannot meet the needs, developers can encapsulate custom components according to their own needs. Creating a custom component requires the following steps:

1. Create a directory under the components directory of the project and name the directory the name of the custom component.

2. Create a vue file in this directory, which is the code of the custom component.

3. Write the template, style and logic of the custom component in the vue file.

4. Use custom components in the template, for example:

Copy after login

The here is our custom component, used in the template It can create the corresponding element.

2. Use tags

In addition to using components, developers can also directly use HTML tags to create elements, for example:

Copy after login

Here and

are ordinary HTML tags. You can create corresponding elements by using them in templates. However, it should be noted that when using tags to create elements, you cannot use some special attributes of HTML tags, such as class, style, etc., because these attributes will have some differences in UniApp .

3. Summary

The above is the method of creating elements in UniApp. Use built-in components to quickly build basic page elements, while custom components can further meet developer needs. At the same time, developers can also use HTML tags to create elements, but they need to be careful to avoid using some special attributes. Mastering these methods can allow developers to create page elements more flexibly and efficiently and improve development efficiency.
