Vue3 vite中使用‘quill editor’无法绑定数据模型（前端开发初学者）

Question

这是我的代码案例研究：

1. 依赖关系

   "dependencies": {
   "@vueup/vue-quill": "^1.2.0",
   "element-plus": "^2.6.3",
   "quill": "^1.3.7",
   "vue": "^3.4.21"

2.index.vue(路径[src/compents/Editor/index.vue])

1. 我做了以下尝试： 根据检索到的预解，在标签中添加或修改属性'v mode' 'or': value='', 'v mode: content=' '。启动项目后，在页面输入框中输入‘title’，在富文本编辑器中输入‘titletest’，点击提交按钮和重置按钮。同时，打开浏览器的控制台面板。提交按钮的结果为结果1；重置按钮的结果如结果2

结果1：

11111->title
22222->

结果2：

11111->
22222->

2. 我的预期结果： 页面加载时，输入框中加载了我的editorContent.titl属性值，富文本框中显示了我的editorContent.content， 点击提交后，我的内容就可以通过富文本框内容来赋值了。点击重置按钮后，我清除了我的数据模型的值，同时清除了输入框和富文本框内容，达到了和输入框一样的数据双向绑定效果

Answer 1

Quill 不支持 Vue，但可以在 vue 中使用 JS。您可以监听 Quill 编辑器的“text-change”事件来更新变量的值。请参阅下面的代码，其中已实现此功能。

https://codepen.io/Wimmie13/pen/GRLQwoz

<template>
  <div>
    <div ref="editorElement" style="min-height: 150px" />
    <div>
      <strong>Current value is:</strong>
      {{ value }}
    </div>
  </div>
</template>

<script setup>
import Quill from "https://esm.sh/quill";
import { ref, onMounted } from "vue";

const value = ref("<h3>This is my title</h3><p>Some content</p>");
const editorElement = ref(null);

onMounted(() => {
  // Set the content for the editor
  editorElement.value.innerHTML = value.value;

  // Create the Quill editor
  const quill = new Quill(editorElement.value, {
    bounds: ".content-wrapper",
    modules: {
      toolbar: true
    },
    theme: "snow"
  });

  // Set the quill content to the value variable
  quill.on("text-change", function () {
    value.value = quill.root.innerHTML;
  });
});
</script>

<style>
@import "https://cdn.jsdelivr.net/npm/[email protected]/dist/quill.base.css";
@import "https://cdn.jsdelivr.net/npm/[email protected]/dist/quill.snow.css";
</style>
