vue 使用vue-quill-editor 富文本添加源码模式，查看源码功能和表格功能

news2024/11/10 5:05:06

今天接到个需求，在富文本中增加查看源码和增加表格功能，感觉这种功能手拿把掐，但是奈于平时沉迷于移动端有段时间没写pc了，看了下官方感觉一个头两个大，于是在茫茫文档中各种借鉴（抄袭）完成了功能

1.源码功能相对来说比较简单就是自定义工具栏

options: {
 theme: 'snow',
 modules: {
  toolbar: {
     container: [
	  ['bold', 'italic', 'underline', 'strike'], // 加粗 斜体 下划线 删除线
  	  ['blockquote', 'code-block'], // 引用  代码块
	  [{ header: 1 }, { header: 2 }], // 1、2 级标题
	  [{ list: 'ordered' }, { list: 'bullet' }], // 有序、无序列表
	  [{ script: 'sub' }, { script: 'super' }], // 上标/下标
	  [{ indent: '-1' }, { indent: '+1' }], // 缩进
	  [{ direction: 'rtl' }], // 文本方向
	  ['link', 'image', 'video'], // 链接、图片、视频
	  [{ align: [] }], // 添加居中按钮
	  [{ color: [] }], // 文字颜色按钮
	  ['sourceEditor'],//新添加源码的工具
	 ]
   }
 }
}

在handlers中添加事件

handlers: {
     sourceEditor: function () {     //添加工具方法
       const reg = /\<br\>/g,
         container = this.container,
         firstChild = container.nextElementSibling.firstChild;
       if (!this.shadeBox) {
         let shadeBox = this.shadeBox = document.createElement('div');
         shadeBox.style.cssText = 'position:absolute; top:0; left:0; width:100%; height:100%; background:rgba(0,0,0,0.5); cursor:pointer';
         container.style.position = 'relative';
         shadeBox.addEventListener('click', function () {
           this.style.display = 'none';
           firstChild.innerHTML = firstChild.innerText.trim();
         }, false);
         container.appendChild(shadeBox);
         let innerHTML = firstChild.innerHTML;
         innerHTML = innerHTML.replace(reg, '');
         firstChild.innerText = innerHTML;
       } else {
         let innerHTML = firstChild.innerHTML;
         innerHTML = innerHTML.replace(reg, '');
         firstChild.innerText = innerHTML;
         this.shadeBox.style.display = 'block';
       }
     }
   },

在mounted中增加显示图标

mounted() {
this.$el.querySelector(
  '.ql-sourceEditor'
 ).innerHTML = `<i class="el-icon-edit"></i>`
}

效果图
在这里插入图片描述

增加表格功能

1.将quill的版本升级到2.0 切记切记切记

npm install quill@2.0.0-dev.4

2.将富文本封装成一个子组件（和查看源码的代码一起，太懒了懒得拆分讲解）

  <div>
    <div class="editor"></div>
  </div>
 
</template>

3.在父组件中用

<template>
  <div>
	  <editor-quill
	   ref="myQuillEditor"
	   v-model="content"
	   class="my-quill-editor"
	   />
 </div>
</template>
<script>
import editorQuill from '../editorQuill'
export default {
  components: {
    editorQuill,
  },
  data() {
    return {
       content:''
    }
  }
}
</script>
