With the popularity of web applications, more and more websites require interactive and editable functions. One way to achieve interactivity and editability is to use a JavaScript library such as jQuery. jQuery is a lightweight JavaScript library that makes front-end web development easier and more efficient. In this article, we will introduce how to use jQuery to implement drag-and-drop editable modules.

1. Create HTML layout

Before using jQuery to implement a draggable editable module, you first need to create an HTML layout. Here is a simple HTML layout for displaying a draggable editable module:

<div class="draggable">
  <div class="content">
    <p>这是一个可编辑模块</p>
    <p>这里可以编辑内容</p>
  </div>
</div>

Copy after login

Please note that we added the class on the

tag ="draggable" to use jQuery to turn it into a draggable module.

2. Add jQuery code

The next step is to add jQuery code to the HTML. Using jQuery, we can easily grab the draggable module and add draggable and editable functionality to it. The following is a sample jQuery code:

$(function() {
  $(".draggable").draggable();
  $(".draggable").attr("contenteditable", "true");
});

Copy after login

In the above code, we use the draggable() method of jQuery UI to make elements of the .draggable class can be dragged . We also set the contenteditable attribute to true using the attr() method to make the element editable.

3. Beautify the editable module

After adding draggable and editable functions, we can beautify the editable module by adding styles. The following are some basic CSS styles for beautifying elements of the .draggable class:

.draggable {
  border: 1px solid #ccc;
  background-color: #ececec;
  padding: 10px;
  width: 200px;
  height: 100px;
}

Copy after login

The above code sets the border and background color of the .draggable class element , padding, width and height.

4. Complete sample code

The following is the complete sample code, including HTML and jQuery code:

<!DOCTYPE html>
<html>
<head>
  <meta charset="UTF-8">
  <title>可拖拽可编辑模块</title>
  <style>
    .draggable {
      border: 1px solid #ccc;
      background-color: #ececec;
      padding: 10px;
      width: 200px;
      height: 100px;
    }
  </style>
  <script src="https://code.jquery.com/jquery-3.5.0.min.js"></script>
  <script src="https://code.jquery.com/ui/1.12.1/jquery-ui.min.js"></script>
  <script>
    $(function() {
      $(".draggable").draggable();
      $(".draggable").attr("contenteditable", "true");
    });
  </script>
</head>
<body>
  <div class="draggable">
    <div class="content">
      <p>这是一个可编辑模块</p>
      <p>这里可以编辑内容</p>
    </div>
  </div>
</body>
</html>

Copy after login

In this example, we import jQuery and jQuery UI libraries HTML page, and use jQuery code to turn elements of the .draggable class into draggable and editable modules.
