React中使用Vditor自定义图片详解

npm install vditor -s

import Vditor from "vditor";

import "vditor/src/assets/scss/index.scss";

export default class Vditor extends Component {
 constructor(props) {
   super(props);
   this.state = {
    editValue: ""
   };
 }
 compOnentDidMount= () => {
  //组件挂载完成之后调用 注意一定要在组件挂载完成之后调用 否则会找不到注入的DOM
  this.createVidtor({ value: this.state.editValue });
 }
 //创建编辑器 下面会详解
 createVidtor = params => {
   let { value } = params;
   value = value &＃63; value : " ";
   let that = this;
   const vditor = new Vditor("vditor", {
     height: 800,
     mode: "ir", //及时渲染模式
     placeholder: "React Vditor",
     toolbar: [
       "emoji",
       "headings",
       "bold",
       "italic",
       "strike",
       "link",
       "|",
       "list",
       "ordered-list",
       "check",
       "outdent",
       "indent",
       "|",
       "quote",
       "line",
       "code",
       "inline-code",
       "insert-before",
       "insert-after",
       "|",
       "upload",
       "table",
       "|",
       "undo",
       "redo",
       "|",
       "fullscreen",
       "edit-mode",
       {
         name: "more",
         toolbar: [
           "both",
           "code-theme",
           "content-theme",
           "export",
           "outline",
           "preview",
           "devtools",
           "info",
           "help"
         ]
       },
       "|",
       {
         hotkey: "&＃8984;-S",
         name: "save",
         tipPosition: "s",
         tip: "保存",
         className: "right",
         icon: `

获取值

saveDoc = () => {
 //在初始化时已经把vditor赋值到this对象上 可直接通过getValue方法获取当前编辑器的值
  let mdValue = this.vditor && this.vditor.getValue();
 //获取完值业务保存就行 这里不再详细写本人的保存方法了
 ...
}

赋值

let { value } = params;
value = value &＃63; value : " ";
//如果是空值的话 最好给一个空格 以免编辑器初始化时报错
const vditor = new Vditor("vditor", {
 // value: value,
 after() {
   vditor.setValue(value);
 }
});
//tip：虽说官方也提供value直接赋值 但是在React里面不生效，就需要在after里面去调用setValue来完成赋值

自定义图片上传

const vditor = new Vditor("vditor", {
 upload: {
   accept: "image/*",
   multiple: false,
   filename(name) {
     return name
       .replace(/[^(a-zA-Z0-9\u4e00-\u9fa5\.)]/g, "")
       .replace(/[\&＃63;\\/:|<>\*\[\]\(\)\$%\{\}@~]/g, "")
       .replace("/\\s/g", "");
   },
   handler(files) {
     function callback(path) {
       let name = files[0] && files[0].name;
       let succFileText = "";
       if (vditor && vditor.vditor.currentMode === "wysiwyg") {
         succFileText += `\n `;
       } else {
         succFileText += ` \n![${name}](${path})`;
       }
       document.execCommand("insertHTML", false, succFileText);
     }
     that.handleImageUpload(files, callback);
   },
   url(files, callback) {
     that.handleImageUpload(files, callback);
   }
 }
});
//此接口里面调用的是自己的图片上传 业务方自行实现
handleImageUpload = (file, callback) => {
  const reader = new FileReader();
  let formdata = new FormData();
  formdata.append("files", file[0]);
  reader.Onload= () => {
    // setTimeout 模拟异步上传图片
    // 当异步上传获取图片地址后，执行callback回调（参数为imageUrl字符串），即可将图片地址写入markdown
    new Promise(resolve => {
      this.props.dispatch({
        type: "docManager/imageUpload",
        payload: { resolve, username: myInfo.userId, formdata }
      });
    }).then(res => {
      let imgurl = res.result.path;
      callback(imgurl);
    });
  };
  reader.readAsDataURL(file[0]);
};




  

    

      
参数
      
说明
    
  
  

    

      
accept
      
接收文件类型（我这边只做了图片上传）
    
    

      
multiple
      
是否多选
    
    

      
filename
      
格式化文件名
    
    

      
handler
      
点击数触发方法
    
    

      
url
      
配置此方法时可实现图片粘贴并上传
    
  



上传完成后接口返回的CDN地址

上传完成后处理

handler(files) {
  function callback(path) {
    let name = files[0] && files[0].name;
    let succFileText = "";
    //上传完成获取当前编辑器模式 根据不同模式拼接不同的展示标签
    if (vditor && vditor.vditor.currentMode === "wysiwyg") {
      succFileText += `\n `;
    } else {
      succFileText += ` \n![${name}](${path})`;
    }
    //拼接完直接插入到鼠标选中位置
    document.execCommand("insertHTML", false, succFileText);
  }
  that.handleImageUpload(files, callback);
}
