Vue component development: implementation of rich text editor

With the rapid development of the Internet, rich text editor has become an indispensable part of modern web applications . The rich text editor provides richer editing functions, allowing users to easily modify text styles, insert pictures, create links, etc.

In Vue.js, we can use various plug-ins and libraries to implement rich text editors. This article will introduce a rich text editor developed using Vue.js and Quill.js libraries.

Quill.js is a JavaScript-based rich text editor library that provides many rich editing functions and works well with Vue.js. To start using Quill.js, we first need to install it:

npm install quill

Then, introduce Quill.js in our Vue component and create a custom rich text editor component.

<template>
  <div>
    <div ref="editor" :class="{'ql-toolbar': mode === 'full'}"></div>
    <div v-html="content"></div>
  </div>
</template>

<script>
import Quill from 'quill';

export default {
  props: {
    mode: { // 编辑模式，'full'表示完整编辑器，'view'表示只读视图
      type: String,
      default: 'full'
    },
    content: { // 编辑器内容
      type: String,
      default: ''
    }
  },
  mounted() {
    this.initEditor();
  },
  methods: {
    initEditor() {
      this.editor = new Quill(this.$refs.editor, {
        theme: 'snow', // 主题样式
        readOnly: this.mode === 'view', // 是否只读
        placeholder: '请输入内容...', // 占位符
        modules: { // 配置模块
          toolbar: [
            ['bold', 'italic', 'underline', 'strike'], // 文本样式
            ['link', 'image', 'video'], // 插入链接、图片、视频
            [{ 'align': [] }] // 文本对齐
          ]
        }
      });

      this.editor.setContents(this.editor.clipboard.convert(this.content));
    }
  }
};
</script>

In the above code, we create a Vue component named <RichTextEditor>, which accepts two properties: mode and content. The mode attribute specifies the editor mode, which can be 'full' for a complete editor or 'view' for a read-only view. The content attribute is used to pass the content of the editor.

In the mounted hook function of the component, we call the initEditor method to initialize the editor. In this method, we use new Quill to create a Quill instance and pass in a DOM element as the container of the editor. Obtain the reference of the DOM element through this.$refs.editor.

When initializing the editor, we can configure various parameters, such as theme style, read-only, placeholder text and toolbar settings, etc. In the above code, we use a default toolbar configuration, which includes commonly used text styles, inserting links, inserting pictures, adjusting text alignment, etc.

Finally, set the content of the editor by calling the this.editor.setContents method and convert this.content into a format acceptable to the Quill editor.

In order to use the rich text editor component, we can introduce and pass the corresponding properties in the parent component.

<template>
  <div>
    <rich-text-editor mode="full" v-model="content" />
  </div>
</template>

<script>
import RichTextEditor from '@/components/RichTextEditor.vue';

export default {
  components: {
    RichTextEditor
  },
  data() {
    return {
      content: '' // 编辑器内容
    };
  }
};
</script>

In the above code, we introduced the <richtexteditor></richtexteditor> component in the parent component and used the v-model directive to bidirectionally bind contentproperty to get the editor's content in the parent component.

Through the above steps, we have successfully implemented a rich text editor component based on Vue.js and Quill.js. We can use this component in the parent component as needed, and flexibly adjust the toolbar configuration and editor style to meet business needs.

Summary:

In this article, we introduced how to use the Vue.js and Quill.js libraries to develop a rich text editor. Using Quill.js can provide rich editing functions and integrate well with Vue.js. We created a custom rich text editor component and explained the implementation details inside the component. I hope this article will help you understand and implement a rich text editor.
