How to use Layui to implement drag-and-drop search and filtering functions
Background introduction:
With the rapid development of the Internet, the amount of data continues to grow, how to efficiently Filtering and searching data has become an important issue. Layui is a lightweight front-end UI framework with rich components and plug-ins that can easily implement various functions. This article will introduce how to use Layui to implement a drag-and-drop search and filter function to facilitate users to customize search conditions according to their own needs.
Implementation ideas:
- Use the table component in Layui to display data and add a search bar.
- Use Layui's layer component to implement pop-up windows for user-defined search conditions.
- Use the form component in Layui to generate a search form.
- Use Layui's drag-and-drop component to implement drag-and-drop search and filtering functions.
Specific implementation:
HTML part:

});Summary:
Using Layui components and plug-ins, We can easily implement drag-and-drop search and filter functions. Through pop-up windows and form components, users can customize search criteria. Combined with the table component, we can display data and dynamically search and filter based on the user's filtering conditions. Such a function can greatly improve users' search efficiency and provide a better user experience.
