毕业涉及中使用到了富文本框,所以学习使用了wangeditor富文本框,现进行总结
1.安装
npm install @wangeditor/editor --save
npm install @wangeditor/editor-for-vue@next --save
2.配置wangeditor组件(src/components/wangeditor.vue)文章来源:https://www.toymoban.com/news/detail-609410.html
<template>
<div style="border: 1px solid #ccc">
<Toolbar
style="border-bottom: 1px solid #ccc"
:editor="editorRef"
:defaultConfig="toolbarConfig"
:mode="mode"
/>
<Editor
style="min-height: 250px; overflow-y: hidden;"
v-model="valueHtml"
:defaultConfig="editorConfig"
:mode="mode"
@onCreated="handleCreated"
/>
</div>

//script标签中引入

export default {
components: { Editor, Toolbar },
setup(props,{emit}) {
emits: ['select']
// 编辑器实例,必须用 shallowRef
const editorRef = shallowRef()
// 内容 HTML
const valueHtml = ref('')
//配置功能栏
let toolbarConfig = {
toolbarKeys: [

const uploadImageList = ref([])
const saveImageList = ref([])
//上传本地图片
function update(file,insertFn) {
let formData = new FormData()
formData.append('file', file)
axios.post('http://localhost:8080/api/file/upload',formData,{

}
//编辑器配置
let editorConfig = {
placeholder: '请输入内容...',
// 所有的菜单配置,都要在 MENU_CONF 属性下
MENU_CONF: {
insertImage:{
onInsertedImage: getOnInsertedImage()
},
// 配置上传图片
uploadImage: {
customUpload: update
}
}
}
// 组件销毁时,也及时销毁编辑器
onBeforeUnmount(() => {

return JSON.parse(JSON.stringify(obj));

console.log('created', editor)
}

//当编辑器的内容发生变化时,把值传给父组件
emit('select', valueHtml.value)
})
const handleChange = (editor) => { console.log('change:', editor.children) }
const handleDestroyed = (editor) => { console.log('destroyed', editor) }
const handleFocus = (editor) => { console.log('focus', editor) }
const handleBlur = (editor) => { console.log('blur', editor) }
const customAlert = (info, type) => { alert(`【自定义提示】${type} - ${info}`) }
const customPaste = (editor, event, callback) => {
console.log('ClipboardEvent 粘贴事件对象', event)
// const html = event.clipboardData.getData('text/html') // 获取粘贴的 html
// const text = event.clipboardData.getData('text/plain') // 获取粘贴的纯文本
// const rtf = event.clipboardData.getData('text/rtf') // 获取 rtf 数据(如从 word wsp 复制粘贴)
// 自定义插入内容
editor.insertText('xxx')
// 返回 false ,阻止默认粘贴行为
event.preventDefault()
callback(false) // 返回值(注意,vue 事件的返回值,不能用 return)
// 返回 true ,继续默认的粘贴行为
// callback(true)
}
//父组件调用子组件的方法清空编辑器内容
const abc =function (){
valueHtml.value = ''
}
//暴露该方法,defineExpose要引入
defineExpose({
abc
})
return {
editorRef,
valueHtml,
mode: 'default', // 或 'simple'
toolbarConfig,
editorConfig,
handleCreated,
handleChange,
handleDestroyed,
handleFocus,
handleBlur,
customAlert,
customPaste,
abc,
};
}
}
3.父组件中文章来源地址https://www.toymoban.com/news/detail-609410.html
//引入
import WangEditor from '../../../components/WangEditor.vue'
//注册
components: {
WangEditor
},
<a-form-model-item :wrapper-col="{ offset: 2, span: 24 }" name="introduction">
<div>课程介绍:</div><br>
<WangEditor
class="WangEditor"
@select="getRich"
ref="childrenRef"
/>
</a-form-model-item>
//当编辑器的内容更新时,获取该值
const getRich = function (value){
state.introduction = value
console.log(value)
}
//获取dom元素
const childrenRef = ref(null)
······
//调用子组件的方法清空编辑器内容
childrenRef.value.abc()
