在vue中使用wangeditor

在vue中使用wangeditor

wangeditor是一个轻量级富文本编辑器可见网址

一、v4版本使用

创建一个config.js文件：

export default {
    menus: [
        "head",
        "bold",
        "fontSize",
        // "fontName",
        "italic",
        "underline",
        '|',
        "strikeThrough",
        "indent",
        "lineHeight",
        "foreColor",
        "backColor",
        "link",
        '|',
        "list",
        // "todo",
        "image",
        "justify",
        // "quote",
        // "table",
        '|',
        "code",
        "splitLine",
        "undo",
        "emoticon",
        "redo",
    ],
    colors: ["#000000", "#eeece0", "#1c487f", "#4d80bf", "#f7acbc", "#5f5d46", "#deab8a", "#fedcbd", "#f0dc70", "#ef5b9c", "#7fb80e", "#d71345", "#aa363d", "#cbc547", "#0c212b", "#8a8c8e"],
    initEmotions: {
        title: "笑脸", // tab 的标题
        type: "emoji", // 'emoji' / 'image'
        content: "                                      ☹                                                         ☠             ".split(
            /\s/
        ),
    },
}

创建一个vue文件：

<template>
  <div class="ED">
    <div ref="editor" :id="id"></div>
  </div>
</template>
<script>
import {
  onMounted,
  defineComponent,
  onBeforeUnmount,
  ref,
  reactive,
  watchEffect,
} from "vue";

// 引入wangeditor组件
import WangEditor from "wangeditor";
// 引入代码高亮组件
// import hljs from "highlight.js";
import config from "./config.js";
export default defineComponent({
  name: "Wangeditor",
  props: {
    contentHtml: {
      type: String,
      default: "",
    },
    id: {
      type: String,
      default: "editor",
    },
  },
  components: { Dialog, ImageList },
  setup(props, content) {
    const state = reactive({
      editorData: "",
      menus: config.menus,
      initEmotions: config.initEmotions,
      colors: config.colors,
      dialogVisible: false,
      isShow: false,
      show: false,
    });
    // 获取编辑器实例html
    const editor = ref();
    // 编辑器实例对象
    let instance = "";
    onMounted(() => {
      // 编辑器实例对象
      instance = new WangEditor(editor.value);
      //   instance = new WangEditor("#" + props.id);
      instance.config.colors = state.colors;
      let emotionsLis = [];
      emotionsLis.push(state.initEmotions);
      instance.config.emotions = emotionsLis;
      // 自定义菜单
      instance.config.menus = state.menus;

      // 代码高亮
      // instance.highlight = hljs;
      // 开启本地上传图片(这是后端上传链接)
      //   instance.config.uploadImgServer = "/upload-img";
      // 限制上传图片格式
      //   instance.config.uploadImgAccept = ["jpg", "jpeg", "png", "gif", "bmp"];
      // 开启本地上传视频(这是后端上传链接)
      // instance.config.uploadVideoServer = "/api/upload-video";
      // 设置编辑器高度
      instance.config.height = 500;
      // 设置编辑器页面层级
      instance.config.zIndex = 10;
      // 设置编辑器placeholder
      instance.config.placeholder = "请输入您的文字！";
      // 忽略粘贴内容中的图片
      instance.config.pasteIgnoreImg = true;
      instance.config.customUploadImg = (files, insert) => {
        console.log(files);
        // 这里用自己的上传方式上传图片
        insert("");
      };
      //  let changeRadio = (data) => {
      //   console.log(data);
      // };
      Object.assign(instance.config, {
        // wangeditor 值发生变化的时候
        onchange() {
          // 将值instance.txt.html() 传递至父组件
          // console.log(instance.txt.html());
          content.emit("update:contentHtml", instance.txt.html());
        },

        // 上传网络图片回调
        // linkImgCallback(src) {
        //   console.log("图片 src ", src);
        // },
        // 上传网络视频回调
        onlineVideoCallback(video) {
          // 自定义回调内容，内容成功插入后会执行该函数
          console.log("插入视频内容", video);
        },
      });
      instance.create();

      // 设置富文本编辑器的页面内容，父组件传递的

      instance.txt.html(props.contentHtml);

      function initData() {
        instance.txt.html(props.contentHtml);
      }

      watchEffect(initData);
    });
    //  页面卸载
    onBeforeUnmount(() => {
      instance.destroy();
      instance = null;
    });
    return {
      editor,
    };
  },
});
</script>

二、v5版本使用

代码如下（示例）：

<template>
  <div style="border: 1px solid #ccc">
    <Toolbar
      :editorId="id"
      style="border-bottom: 1px solid #ccc"
      :editor="editorRef"
      :mode="mode"
      :defaultConfig="toolbarConfig"
    />
    <Editor
      :editorId="id"
      style="min-height: 500px"
      v-model="valueHtml"
      :defaultConfig="editorConfigNew"
      @onChange="handleChange"
      :mode="mode"
      @onCreated="handleCreated"
      @onFocus="handleFocus"
      @customPaste="customPaste"
    />
  </div>
</template>

<script>
import "@wangeditor/editor/dist/css/style.css"; // 引入 css
import {
  defineComponent,
  onBeforeUnmount,
  ref,
  shallowRef,
  onMounted,
} from "vue";
import { Editor, Toolbar } from "@wangeditor/editor-for-vue";
export default defineComponent({
  props: {
    contentHtml: {
      type: String,
      default: "",
    },
    id: {
      type: String,
      default: "editor",
    },
  },
  components: { Editor, Toolbar },
  setup(props, content) {
    // 编辑器实例，必须用 shallowRef
    const editorRef = shallowRef();
    const editor = shallowRef();

    // 内容 HTML
    const valueHtml = ref("");

    const toolbarConfig = {
      // excludeKeys: ["uploadVideo", "uploadImage", "fullScreen"],
      excludeKeys: ["uploadVideo", "fullScreen"],
    };
    const editorConfigNew = { placeholder: "请输入内容...", MENU_CONF: {} };
    editorConfigNew.MENU_CONF["uploadImage"] = {
      // 自定义上传
      async customUpload(file, insertFn) {
        // file 即选中的文件
        // 自己实现上传，并得到图片 url alt href
        // 最后插入图片
        // insertFn(url, alt, href);
        // console.log(file)
        insertFn(
          ""
        );
      },
    };
    // editorConfig.MENU_CONF["uploadImage"] = {
    //   // 自定义选择图片
    //   customBrowseAndUpload(insertFn) {
    //     // 自己选择文件
    //     // 自己上传文件，并得到图片 url alt href
    //     // 最后插入图片
    //     insertFn(url, alt, href);
    //   },
    // };
    // 组件销毁时，也及时销毁编辑器
    onBeforeUnmount(() => {
      const editor = editorRef.value;
      if (editor == null) return;
      editor.destroy();
    });

    const handleCreated = (editor) => {
      // console.log("created", editor.getAllMenuKeys());
      // console.log("created", editor);
      editorRef.value = editor;
    };

    const handleChange = () => {
      const editor = editorRef.value; // 获取 editor ，必须等待它渲染完之后
      if (editor == null) return;
      content.emit("update:contentHtml", editor.getHtml());
    };
    const handleFocus = () => {};
    const customPaste = (editor, event, callback) => {
      let text = event.clipboardData.getData();
      // 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(text);
      // 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)
    };

    onMounted(() => {});
    const insertText = (val) => {
      const editor = editorRef.value;
      if (editor == null) return;
      editor.dangerouslyInsertHtml(val);
    };
    return {
      editorRef,
      valueHtml,
      mode: "default", // 或 'simple','default'
      toolbarConfig,
      editorConfigNew,
      handleCreated,
      handleChange,
      handleFocus,
      customPaste,
      editor,
      insertText,
    };
  },

  data() {
    return {};
  },
  methods: {},
});
</script>
<style lang="scss" scoped>
</style>
