uniapp editor富文本编辑器，h5富文本编辑器封装成插件

公司业务需求，需要在h5实现富文本编辑功能。uniapp的editor可以实现富文本编辑，但是editor只有编辑框，没有给文本设置样式的工具栏。于是自己组装了一个。效果如下图，实现了文本的字体、颜色、加粗、斜体、下划线、删除线、对齐方式、有序/无序/列表、插入图片、返回、撤销、清空等常见功能。
用到的插件：color-picker(颜色选择插件，插件市场下载)、editor(uniapp自带，无需下载)。
封装插件名称：editor-rich
插件使用：
<view class="editor">
<EditorContext id="editor" :readOnly="false" maxlength="3000" :values="subjectContent" @changes="saveContens">
</EditorContext>
<text>已输入{{stepCount}}/3000</text>
</view>
// 首先要在引用页面引入插件
import EditorContext from '@/components/editor-rich/editor-rich.vue';
// 保存输入的内容
saveContens(e) {
this.subjectContent = e.html;
this.stepCount = e.length;
}
插件代码：
