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:
步骤 1: 安装 wangeditor
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
步骤 2: 引入 wangeditor 到您的组件
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';
步骤 3: 创建编辑器实例和响应式数据
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 }; }, };
步骤 4: 在模板中添加编辑器容器
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>
步骤 5: 配置 wangeditor(可选)
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 }
步骤 6: 获取编辑器内容(可选)
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()); };
步骤 7: 清理资源
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(); });
