How to create a dynamic text editor using HTML, CSS and jQuery

In the current digital era, text editors are indispensable in our daily life and work One of the few tools. Whether we are writing articles, coding or taking notes, a useful text editor can greatly improve our efficiency and comfort. This article will introduce how to use HTML, CSS and jQuery to create a dynamic text editor, and provide some specific code examples for your reference.

HTML Structure

First, we need to create a basic HTML structure. The following is a simple HTML frame that can be used as a container for a text editor:

<!DOCTYPE html>
<html>
  <head>
    <title>动态文本编辑器</title>
    <link rel="stylesheet" type="text/css" href="style.css">
  </head>
  <body>
    <div id="editor">
      <textarea id="textArea"></textarea>
    </div>

    <script src="jquery.min.js"></script>
    <script src="script.js"></script>
  </body>
</html>

Copy after login

In this HTML structure, we use a <div> element as a container for the text editor Container, which contains a <textarea> element for user input text. At the same time, we set an id as "editor" for this <div> element for subsequent CSS styling and jQuery operations.

CSS Style

Next, we need to add some CSS styles to beautify our text editor. The following is a basic CSS style example:

#editor {
  width: 800px;
  height: 400px;
  margin: 0 auto;
  padding: 10px;
  border: 1px solid #ccc;
  background-color: #fff;
}

textarea {
  width: 100%;
  height: 100%;
  padding: 5px;
  font-size: 14px;
  border: none;
  outline: none;
  resize: none;
}

Copy after login

In this CSS style, we set some basic styles for the text editor container and input box, including width, height, border, background color, etc. You can also customize it according to your needs.

jQuery Operation

Finally, we need to use jQuery to achieve some dynamic effects and functions. The following is a simple jQuery operation example:

$(document).ready(function() {
  // 当文本输入框中的内容发生变化时
  $('#textArea').on('input', function() {
    var text = $(this).val(); // 获取文本输入框的内容
    $('#editor').prepend('<p>' + text + '</p>'); // 在编辑器中添加一行文本
  });
});

Copy after login

In this jQuery operation, we use $(document).ready() to ensure that the page is loaded before executing our operation . When the content in the text input box changes, we use the $('#textArea').on('input', function() { ... }) function to listen to the input event of the input box . In the event handler function, we obtain the content of the input box through $(this).val(), and use $('#editor').prepend('<p>' text '</p>')Add the content of the input box as a line of text to the editor.

With the above HTML structure, CSS styles and jQuery operations, we can create a simple dynamic text editor. When the user enters content in the input box, the input content will be added to the text editor in real time.

Of course, the above example is just a basic implementation. You can extend and modify it according to your own needs, and add more functions and styles, such as saving text, inserting pictures, etc.
