一、用到的技術(shù)
1弛随、技術(shù)棧
react: ^16.14.0
react-dom:^17.0.0
react-quill: ^1.3.5 富文本編輯器
react-router: ^4.3.1
react-dev-inspector：^1.1.1 這個(gè)包允許用戶通過簡(jiǎn)單的點(diǎn)擊直接從瀏覽器 React 組件跳轉(zhuǎn)到本地 IDE 代碼
2、UI組件
Ant Design --------------------------用到版本： antd: 4.15.1

二墨林、用法總結(jié)
1敬惦、富文本
這里有個(gè)坑谣膳，如果和自定義下拉選項(xiàng)一起使用，得下拉框渲染完之后才能渲染富文本組件，不然會(huì)報(bào)錯(cuò),加不了必填項(xiàng)
import ReactQuill,{ Quill } from 'react-quill';
import QuillEmoji from 'quill-emoji'
import 'quill-emoji/dist/quill-emoji.css'
import 'react-quill/dist/quill.snow.css'
Quill.register({
'modules/emoji-toolbar': QuillEmoji.ToolbarEmoji,
// 'modules/emoji-textarea': QuillEmoji.TextAreaEmoji,
'modules/emoji-shortname': QuillEmoji.ShortNameEmoji
})
const modules={
toolbar:{
container:[
[{ 'size': ['small', false, 'large', 'huge'] }], // custom dropdown
[{ 'font': [] }],
[{ 'header': 1 }, { 'header': 2 }], // custom button values
['bold', 'italic', 'underline', 'strike'], // toggled buttons
[{ 'align': [] }],
[{ 'indent': '-1' }, { 'indent': '+1' }], // outdent/indent
[{ 'direction': 'rtl' }], // text direction
[{ 'script': 'sub' }, { 'script': 'super' }], // superscript/subscript
['blockquote', 'code-block'],
[{ 'list': 'ordered' }, { 'list': 'bullet' }],
[{ 'color': [] }, { 'background': [] }],
['emoji', 'image', 'video', 'link'],
['clean']
],
handlers: {
image: ()=>imageHandler()
}
},
'emoji-toolbar': true,
// 'emoji-textarea': true,
'emoji-shortname': true,
}
//自定義上傳圖片格式
const imageHandler = () => {
const quillEditor = ref.current?.getEditor()
const input = document.createElement('input')
input.setAttribute('type', 'file')
input.setAttribute('accept', 'image/*')
input.click()
input.onchange = async () => {
const file = input.files[0]
const formData = new FormData()
formData.append('quill-image', file)
const code=218
const link=await upload(file,code)//把base64格式轉(zhuǎn)換為正常url路徑格式,自定義方法
const range = quillEditor?.getSelection()
quillEditor.insertEmbed(range.index, 'image', link)
}
}
{
onselect.length>0&&//如果和自定義下拉選項(xiàng)一起使用溉委，得下拉框渲染完之后才能渲染富文本組件鹃唯，不然會(huì)報(bào)錯(cuò)
<div className={styles.box}>
<Form.Item
label="文章詳情"
name="articleContent"
readonly={detailData?.id&&detailData?.edtil}
// rules={[{ required: true, message: '請(qǐng)?jiān)O(shè)置文章詳情!' }]}
>
<ReactQuill modules={modules} ref={ref}/>
</Form.Item>
<div className={styles.mark}>*</div>

}
1.1、base64轉(zhuǎn)url路徑upload方法
import OSS from 'ali-oss';
import request from '@/utils/request';
const getConfig = (params = {}, options = {}) => {
return request('/auth/goods/product/getOssConfig', {
method: 'POST',
data: params,
...options
});
}
const getImageSize = (file) => {
return new Promise((resolve) => {
const reader = new FileReader()
reader.readAsDataURL(file)
reader.onload = (theFile) => {
const image = new Image()
image.src = theFile.target.result
image.onload = function () {
const { width, height } = this;
resolve({ width, height })
}
}
});
}
let ossConfig = null;
let codeTemp = null
const upload = async (file, code) => {
if (code !== codeTemp) {
ossConfig = null
}
codeTemp = code;
if (!ossConfig) {
const res = await getConfig({ code });
ossConfig = res?.data?.records
}
const client = new OSS({
region: `oss-${ossConfig.regionId}`,
accessKeyId: ossConfig.credentials.accessKeyId,
accessKeySecret: ossConfig.credentials.accessKeySecret,
stsToken: ossConfig.credentials.securityToken,
bucket: ossConfig.uploadInfo.bucket,
})
return new Promise((resolve) => {
client.put(`${ossConfig.uploadInfo.dir}/${file.uid}-y_g-${file.name}`, file).then(res => {
if (file.type.indexOf('image') !== -1) {
getImageSize(file).then(size => {
resolve(`${res.url}?imgHeight=${size.height}&imgWidth=${size.width}`)
})
} else {
resolve(res.url);
}
}).catch(err => {
ossConfig = null;
// return upload(file, dirName)
console.log('上傳失敯旰啊：', err)
})
})
}
export default upload;
2坡慌、上傳圖片右邊添加圖片描述不影響Form表單提交的方法
企業(yè)微信截圖_16451702601132.png
const FromWrap = ({ value, onChange, content, right }) => (
<div style={{ display: 'flex' }}>
<div>{content(value, onChange)}</div>
<div style={{ flex: 1, marginLeft: 10, minWidth: 180 }}>{detailData?.id&&detailData?.edtil?null:right(value)}</div>
</div>
)
<Form.Item
label="封面圖片"
name="coverPicture"
rules={[{ required: true, message: '請(qǐng)上傳圖片!' }]}
readonly={detailData?.id&&detailData?.edtil}
>
<FromWrap
content={(value, onChange) => <Upload multiple value={value} onChange={onChange} maxCount={1} accept="image/*" size={(1*1024)/2} />}
right={(value) => {
return (
<dl>
<dt>圖片要求</dt>
<dd>1.圖片大小500kb以內(nèi)</dd>

<dd>3.圖片格式png/jpg/gif</dd>
