wangeditor 官网指南
在Vue项目中使用wangeditor
构建富文本编辑器,您需要遵循以下步骤来集成和使用这个流行的编辑器:
首先,您需要在Vue项目中安装wangeditor
。可以通过npm来完成安装:
yarn add @wangeditor/editor # 或者 npm install @wangeditor/editor --save yarn add @wangeditor/editor-for-vue@next # 或者 npm install @wangeditor/editor-for-vue@next --save
在您希望使用富文本编辑器的Vue组件中,引入wangeditor
:
import '@wangeditor/editor/dist/css/style.css';// 引入编辑器的CSS样式 import { onBeforeUnmount, ref, shallowRef, onMounted } from 'vue'; import { Editor, Toolbar } from '@wangeditor/editor-for-vue';
在Vue组件的mounted
生命周期钩子中,创建wangeditor
的实例,并将其绑定到指定的DOM元素上:
export default { components: { Editor, Toolbar }, setup() { // 编辑器实例,必须用 shallowRef,重要! const editorRef = shallowRef(); // 内容 HTML const valueHtml = ref('<p>hello</p>'); // 模拟 ajax 异步获取内容 onMounted(() => { setTimeout(() => { valueHtml.value = '<p>模拟 Ajax 异步设置内容</p>'; }, 1500); }); const toolbarConfig = {}; const editorConfig = { placeholder: '请输入内容...' }; // 组件销毁时,也及时销毁编辑器,重要! onBeforeUnmount(() => { const editor = editorRef.value; if (editor == null) return; editor.destroy(); }); // 编辑器回调函数 const handleCreated = (editor) => { console.log('created', editor); editorRef.value = editor; // 记录 editor 实例,重要! }; const handleChange = (editor) => { console.log('change:', editor.getHtml()); }; const handleDestroyed = (editor) => { console.log('destroyed', editor); }; const handleFocus = (editor) => { console.log('focus', editor); }; const handleBlur = (editor) => { console.log('blur', editor); }; const customAlert = (info, type) => { alert(`【自定义提示】${type} - ${info}`); }; const customPaste = (editor, event, callback) => { console.log('ClipboardEvent 粘贴事件对象', event); // 自定义插入内容 editor.insertText('xxx'); // 返回值(注意,vue 事件的返回值,不能用 return) callback(false); // 返回 false ,阻止默认粘贴行为 // callback(true) // 返回 true ,继续默认的粘贴行为 }; const insertText = () => { const editor = editorRef.value; if (editor == null) return; editor.insertText('hello world'); }; const printHtml = () => { const editor = editorRef.value; if (editor == null) return; console.log(editor.getHtml()); }; const disable = () => { const editor = editorRef.value; if (editor == null) return; editor.disable() }; return { editorRef, mode: 'default', valueHtml, toolbarConfig, editorConfig, handleCreated, handleChange, handleDestroyed, handleFocus, handleBlur, customAlert, customPaste, insertText, printHtml, disable }; }, };
在Vue组件的模板中,添加一个容器元素来承载wangeditor
:
<div style="border: 1px solid #ccc; margin-top: 10px"> <Toolbar :editor="editorRef" :defaultConfig="toolbarConfig" :mode="mode" style="border-bottom: 1px solid #ccc" /> <Editor :defaultConfig="editorConfig" :mode="mode" v-model="valueHtml" style="height: 400px; overflow-y: hidden" @onCreated="handleCreated" @onChange="handleChange" @onDestroyed="handleDestroyed" @onFocus="handleFocus" @onBlur="handleBlur" @customAlert="customAlert" @customPaste="customPaste" /> </div>
wangeditor
提供了多种配置选项,您可以根据需要进行配置。例如,设置编辑器的自定义菜单、上传图片的接口等:
// const editorConfig = { placeholder: '请输入内容...' }; // 初始化 MENU_CONF 属性 const editorConfig = { // JS 语法 MENU_CONF: {}, placeholder: '请输入内容...' // 其他属性... } // 修改 uploadImage 菜单配置 editorConfig.MENU_CONF['uploadImage'] = { server: '/api/upload-image', fieldName: 'custom-field-name' // 继续写其他配置... //【注意】不需要修改的不用写,wangEditor 会去 merge 当前其他配置 }
您可以通过editor.txt.html()
方法获取编辑器的HTML内容,或者通过editor.txt.text()
获取纯文本内容:
const printHtml = () => { const editor = editorRef.value; if (editor == null) return; console.log(editor.getHtml()); };
当组件销毁时,确保释放编辑器资源,避免内存泄漏:
// 组件销毁时,也及时销毁编辑器,重要! onBeforeUnmount(() => { const editor = editorRef.value; if (editor == null) return; editor.destroy(); });
<template> <div> <div> <button @click="insertText">insert text</button> <button @click="printHtml">print html</button> <button @click="disable">disable</button> </div> <div style="border: 1px solid #ccc; margin-top: 10px"> <Toolbar :editor="editorRef" :defaultConfig="toolbarConfig" :mode="mode" style="border-bottom: 1px solid #ccc" /> <Editor :defaultConfig="editorConfig" :mode="mode" v-model="valueHtml" style="height: 400px; overflow-y: hidden" @onCreated="handleCreated" @onChange="handleChange" @onDestroyed="handleDestroyed" @onFocus="handleFocus" @onBlur="handleBlur" @customAlert="customAlert" @customPaste="customPaste" /> </div> <div style="margin-top: 10px"> <textarea v-model="valueHtml" readonly style="width: 100%; height: 200px; outline: none"></textarea> </div> </div> </template> <script> import '@wangeditor/editor/dist/css/style.css'; import { onBeforeUnmount, ref, shallowRef, onMounted } from 'vue'; import { Editor, Toolbar } from '@wangeditor/editor-for-vue'; export default { components: { Editor, Toolbar }, setup() { // 编辑器实例,必须用 shallowRef,重要! const editorRef = shallowRef(); // 内容 HTML const valueHtml = ref('<p>hello</p>'); // 模拟 ajax 异步获取内容 onMounted(() => { setTimeout(() => { valueHtml.value = '<p>模拟 Ajax 异步设置内容</p>'; }, 1500); }); const toolbarConfig = {}; // const editorConfig = { placeholder: '请输入内容...' }; // 初始化 MENU_CONF 属性 const editorConfig = { // JS 语法 MENU_CONF: {}, placeholder: '请输入内容...' // 其他属性... } // 修改 uploadImage 菜单配置 editorConfig.MENU_CONF['uploadImage'] = { server: '/api/upload-image', fieldName: 'custom-field-name' // 继续写其他配置... //【注意】不需要修改的不用写,wangEditor 会去 merge 当前其他配置 } // 组件销毁时,也及时销毁编辑器,重要! onBeforeUnmount(() => { const editor = editorRef.value; if (editor == null) return; editor.destroy(); }); // 编辑器回调函数 const handleCreated = (editor) => { console.log('created', editor); editorRef.value = editor; // 记录 editor 实例,重要! }; const handleChange = (editor) => { console.log('change:', editor.getHtml()); }; const handleDestroyed = (editor) => { console.log('destroyed', editor); }; const handleFocus = (editor) => { console.log('focus', editor); }; const handleBlur = (editor) => { console.log('blur', editor); }; const customAlert = (info, type) => { alert(`【自定义提示】${type} - ${info}`); }; const customPaste = (editor, event, callback) => { console.log('ClipboardEvent 粘贴事件对象', event); // 自定义插入内容 editor.insertText('xxx'); // 返回值(注意,vue 事件的返回值,不能用 return) callback(false); // 返回 false ,阻止默认粘贴行为 // callback(true) // 返回 true ,继续默认的粘贴行为 }; const insertText = () => { const editor = editorRef.value; if (editor == null) return; editor.insertText('hello world'); }; const printHtml = () => { const editor = editorRef.value; if (editor == null) return; console.log(editor.getHtml()); }; const disable = () => { const editor = editorRef.value; if (editor == null) return; editor.disable() }; return { editorRef, mode: 'default', valueHtml, toolbarConfig, editorConfig, handleCreated, handleChange, handleDestroyed, handleFocus, handleBlur, customAlert, customPaste, insertText, printHtml, disable }; }, }; </script>
