安裝

npm install vditor -s

引用

導入依賴包

import Vditor from "vditor";

導入樣式

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

使用示例

export default class Vditor extends Component {
 constructor(props) {
   super(props);
   this.state = {
    editValue: ""
   };
 }
 componentDidMount = () => {
  //組件掛載完成之后調用 注意一定要在組件掛載完成之后調用 否則會找不到注入的DOM
  this.createVidtor({ value: this.state.editValue });
 }
 //創建編輯器 下面會詳解
 createVidtor = params => {
   let { value } = params;
   value = value ? value : " ";
   let that = this;

}

功能使用

新建對象

const vditor = new Vditor("vditor", ...option);

新建對象時第一個參數ID，要對應上再render里面注入的ID

option參數

tip：只列舉一下常用參數，其他的參數請參照官方API

參數	說明
height	配置編輯器高度
mode	編輯器模式 wysiwyg：所見即所得2 ir:及時渲染 sv：分屏模式
placeholder	占位符
toolbar	工具欄

Tip：如果要自定義工具欄的話，一定要加上默認的工具欄，不然只展示自定義的了

默認工具欄

tip：此為源碼里面copy 不用更改可直接使用，官方已定義好了快捷鍵和功能

toolbar: [
      "emoji",
      "headings",
      "bold",
      "italic",
      "strike",
      "link",
      "|",
      "list",
      "ordered-list",
      "check",
      "outdent",
      "indent",
      "|",
      "quote",
      "line",
      "code",
      "inline-code",
      "insert-before",
      "insert-after",
      "|",
      "upload",
      "record",
      "table",
      "|",
      "undo",
      "redo",
      "|",
      "fullscreen",
      "edit-mode",
      {
        name: "more",
        toolbar: [
          "both",
          "code-theme",
          "content-theme",
          "export",
          "outline",
          "preview",
          "devtools",
          "info",
          "help",
        ],
      }]

對應工具欄展示：

React中使用Vditor自定義圖片詳解

自定義按鈕

let that = this;
const vditor = new Vditor("vditor", {
  toolbar: [
    {
      hotkey: "?-S",
      name: "save",
      tipPosition: "s",
      tip: "保存",
      className: "right",
      icon: `<img style="height: 16px" src="https://img.58cdn.com.cn/escstatic/docs/imgUpload/idocs/save.svg"/>`,
      click() {
        that.saveDoc();
      }
    },
    {
      hotkey: "",
      name: "publish",
      tipPosition: "s",
      tip: "發布文章",
      className: "right",
      icon: `<img style="height: 16px" src="https://img.58cdn.com.cn/escstatic/docs/imgUpload/idocs/publish.svg"/>`,
      click() {
        that.publishDoc();
      }
    }
  ]
});
//tip：在調用本類封裝的方法時提前把this賦值給其他方法內的變量，在Vditor內部改變了this指向

參數	說明
hotkey	熱鍵配置
name	功能區分（唯一性）
tip	懸浮提示
className	UI展示 right靠右
icon	按鈕圖標
click	點擊事件

示例：

React中使用Vditor自定義圖片詳解

獲取值

saveDoc = () => {
 //在初始化時已經把vditor賦值到this對象上 可直接通過getValue方法獲取當前編輯器的值
  let mdValue = this.vditor && this.vditor.getValue();
 //獲取完值業務保存就行 這里不再詳細寫本人的保存方法了
 ...
}

賦值

let { value } = params;
value = value ? value : " ";
//如果是空值的話 最好給一個空格 以免編輯器初始化時報錯
const vditor = new Vditor("vditor", {
 // value: value,
 after() {
   vditor.setValue(value);
 }
});
//tip：雖說官方也提供value直接賦值 但是在React里面不生效，就需要在after里面去調用setValue來完成賦值

自定義圖片上傳

const vditor = new Vditor("vditor", {
 upload: {
   accept: "image/*",
   multiple: false,
   filename(name) {
     return name
       .replace(/[^(a-zA-Z0-9u4e00-u9fa5.)]/g, "")
       .replace(/[?\/:|<>*[]()$%{}@~]/g, "")
       .replace("/\s/g", "");
   },
   handler(files) {
     function callback(path) {
       let name = files[0] && files[0].name;
       let succFileText = "";
       if (vditor && vditor.vditor.currentMode === "wysiwyg") {
         succFileText += `
 <img       } else {
         succFileText += ` 
![${name}](${path})`;
       }
       document.execCommand("insertHTML", false, succFileText);
     }
     that.handleImageUpload(files, callback);
   },
   url(files, callback) {
     that.handleImageUpload(files, callback);
   }
 }
});
//此接口里面調用的是自己的圖片上傳 業務方自行實現
handleImageUpload = (file, callback) => {
  const reader = new FileReader();
  let formdata = new FormData();
  formdata.append("files", file[0]);
  reader.onload = () => {
    // setTimeout 模擬異步上傳圖片
    // 當異步上傳獲取圖片地址后，執行callback回調（參數為imageUrl字符串），即可將圖片地址寫入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]);
};

參數	說明
accept	接收文件類型（我這邊只做了圖片上傳）
multiple	是否多選
filename	格式化文件名
handler	點擊數觸發方法
url	配置此方法時可實現圖片粘貼并上傳

上傳完成后處理

handler(files) {
  function callback(path) {
    let name = files[0] && files[0].name;
    let succFileText = "";
    //上傳完成獲取當前編輯器模式 根據不同模式拼接不同的展示標簽
    if (vditor && vditor.vditor.currentMode === "wysiwyg") {
      succFileText += `
 <img    } else {
      succFileText += ` 
![${name}](${path})`;
    }
    //拼接完直接插入到鼠標選中位置
    document.execCommand("insertHTML", false, succFileText);
  }
  that.handleImageUpload(files, callback);
}
