How to use Layui to implement the collapsible schedule function

Layui is a popular front-end UI framework that is easy to use and has a beautiful interface. Foldable is a common way to implement schedule functions, which can display more schedule information in an orderly and concise manner. This article will introduce how to use Layui to implement the collapsible scheduling function and provide specific code examples.

1. Preparation

First, we need to ensure that the Layui framework has been introduced correctly. It can be introduced through CDN, or you can download the local version and introduce it into the page.

2. HTML structure

In HTML, we need to define a basic container to contain the schedule content. Typically a list (

or

) can be used to hold schedule items (
1. ).

   <div class="schedule-container">
     <ul class="schedule-list">
       <li class="schedule-item">
         <div class="schedule-header">2022-01-01</div>
         <div class="schedule-content">
           <p>日程内容1</p>
           <p>日程内容2</p>
         </div>
       </li>
       <li class="schedule-item">
         <div class="schedule-header">2022-01-02</div>
         <div class="schedule-content">
           <p>日程内容3</p>
         </div>
       </li>
       <!-- 其他日程项 -->
     </ul>
   </div>

   3. CSS styles

   In order to achieve the collapsible effect, we need to define some styles to control the display and hiding of elements.

   .schedule-container {
     width: 300px;
   }
   
   .schedule-list {
     list-style: none;
     padding: 0;
     margin: 0;
   }
   
   .schedule-item {
     margin-bottom: 10px;
   }
   
   .schedule-header {
     padding: 10px;
     background-color: #f2f2f2;
     cursor: pointer;
   }
   
   .schedule-content {
     padding: 10px;
     display: none;
   }

   4. JavaScript code

   In JavaScript, we need to use Layui's modular loading function to introduce element selectors, element operations and event modules respectively.

   layui.use(['jquery', 'element', 'form'], function($) {
     var element = layui.element;
     
     // 打开折叠项
     $('.schedule-header').on('click', function() {
       $(this).siblings('.schedule-content').slideToggle();
       element.render('collapse');
     });
     
     // 折叠全部项
     $('.btn-collapse-all').on('click', function() {
       $('.schedule-content').slideUp();
       element.render('collapse');
     });
     
     // 展开全部项
     $('.btn-expand-all').on('click', function() {
       $('.schedule-content').slideDown();
       element.render('collapse');
     });
   });

   In the above code, we use Layui's modular loading method and control the display and hiding of elements through JQuery selectors and events. When clicking the .schedule-header element, use the slideToggle() method to switch the display state of the .schedule-content element, and use element.render ('collapse')Update the collapse style. In addition, we also provide two buttons for collapsing and expanding all schedule items.

   5. Effect Demonstration

   The above code implements the collapsible schedule function. Click the schedule title to expand or collapse the corresponding content, and it also has global folding and expanding buttons.

   After introducing the above code, we can demonstrate the effect in the following ways:

   1. Click on the schedule title to expand or collapse the corresponding content;
   2. Click " Click the "Collapse All" button to collapse all schedule content;
   3. Click the "Expand All" button to expand all schedule content.

   6. Summary

   Through the above steps, we successfully used Layui to implement the foldable schedule function. By properly laying out the HTML structure, defining styles and writing JavaScript code, we can achieve a more elegant and easy-to-use user interface. I hope this article will be helpful to you when developing with Layui.
