How to use uniapp to implement the login video function

With the development of mobile Internet, APP has become an indispensable part of people's lives. As the number of APPs continues to increase, user login has become an essential task in APP development. How to make the APP login page more personalized and increase user experience has become a more important topic. This article will introduce how to use uniapp to implement the login video function and add more interactivity and dynamics to the APP.

1. Introduction to uniapp

Uniapp is a cross-platform application framework developed by DCloud based on vue.js. It supports compilation to iOS and Android platforms, and can also be compiled to applets and H5 on the platform. In uniapp, you can use the development mode of vue.js, use scss to write styles, and use the uni-ui component library to achieve rich interface effects.

2. Implementation of login video

1. Prepare materials

Firstly, you need to prepare a background video material for the login page. You can usually use videos in MP4 format. We can search for free video materials online, or find a photographer or video production company to customize them. In addition, we also need to prepare a static image as the video cover so that it can be displayed when the video loads.

2. Page structure design

In uniapp, the page is composed of .vue files. We use the video tag to load the video in a new .vue file, and set the autoplay attribute of the video tag to true to automatically play the video. At the same time, a poster attribute needs to be set in the video tag to point to the path of the cover image we prepared. The complete video tag code is as follows:

In addition, in order To make the page more dynamic, we can also set a div element above the video tag to display the APP name, login button and other page elements. For example:

APP name

> ;

Login

3. Implement page style

In the two tags above, we have set up video and page elements. Next, we need to adjust the style according to needs to make the page beautiful, while ensuring that elements such as the APP name and login button will not be blocked. Occlusion.

Here we use the uni-ui component library to achieve style adjustment. The following are some components that may be used:

• uni-icons (used to display icons)
• uni-popup (used for pop-up layer effects)
• uni -nav-bar (for title bar effect)

4. Implement interaction

Finally, we need to add some JavaScript logic code to make the interface have better interactive effect. For example, when the user clicks the "Login" button, a pop-up box should appear to prompt the user whether the login information is correct. We can use the uni-popup component to achieve this function. The sample code is as follows:

Login

{{popupText}}

<button>是</button>
<button>否</button>

Among them, the @click event of the button label is bound to the showPopup method; the v of the uni-popup component -model is bound to the show variable, indicating whether to display the pop-up box; the value of pop-up-text can be changed according to the actual situation.

3. Summary

This article mainly introduces the method of using uniapp to achieve the video effect of the login page, including material production, page structure design, style adjustment and interaction logic implementation. By adding a video element, paired with other elements, you can make your landing page more lively and engaging.
