引言：
在Vue项目的开发过程中，经常需要使用富文本编辑器来处理用户的输入内容。Tinymce 是一个功能强大且易于使用的富文本编辑器，它支持大多数常见的文本编辑功能，并且可以通过插件进行扩展。本文将详细介绍如何在Vue项目中使用Tinymce富文本编辑器。
一、 开始
官网文档：https://www.tiny.cloud/docs/
中文文档：http://tinymce.ax-z.cn/
社区版及开发版官方最新打包地址：https://www.tiny.cloud/get-tiny/self-hosted/
汉化包：http://tinymce.ax-z.cn/static/tiny/langs/zh_CN.js
二、快速开始
1、安装Tinymce
首先，在Vue项目的根目录下打开终端，运行以下命令来安装Tinymce：
npm install tinymce
上述命令会下载并安装Tinymce的依赖到你的项目中。
三、封装成Vue组件
1、文件结构
2、index.vue
<template><div :class="{ fullscreen: fullscreen }" class="tinymce-container" :style="{ width: containerWidth }"><textarea :id="tinymceId" class="tinymce-textarea" /></div>
</template><script>

}
</style>3、dynamicLoadScript.js
//dynamicLoadScript.js 动态导入tinymce.js脚本
let callbacks = []function loadedTinymce() {// to fixed https://github.com/PanJiaChen/vue-element-admin/issues/2144// check is successfully downloaded scriptreturn window.tinymce
}const dynamicLoadScript = (src, callback) => {const existingScript = document.getElementById(src)const cb = callback || function () {}if (!existingScript) {const script = document.createElement('script')script.src = src // src url for the third-party library being loaded.script.id = srcdocument.body.appendChild(script)callbacks.push(cb)const onEnd = 'onload' in script ? stdOnEnd : ieOnEndonEnd(script)}if (existingScript && cb) {if (loadedTinymce()) {cb(null, existingScript)} else {callbacks.push(cb)}}function stdOnEnd(script) {script.onload = function () {// this.onload = null here is necessary// because even IE9 works not like othersthis.onerror = this.onload = nullfor (const cb of callbacks) {cb(null, script)}callbacks = null}script.onerror = function () {this.onerror = this.onload = nullcb(new Error('Failed to load ' + src), script)}}function ieOnEnd(script) {script.onreadystatechange = function () {if (this.readyState !== 'complete' && this.readyState !== 'loaded') returnthis.onreadystatechange = nullfor (const cb of callbacks) {cb(null, script) // there is no way to catch loading errors in IE8}callbacks = null}}
}export default dynamicLoadScript4、plugin.js
// Any plugins you want to use has to be imported
// Detail plugins list see https://www.tinymce.com/docs/plugins/
// Custom builds see https://www.tinymce.com/download/custom-builds/const plugins = ['advlist anchor autolink autosave code codesample colorpicker colorpicker contextmenu directionality emoticons fullscreen hr image imagetools insertdatetime link lists media nonbreaking noneditable pagebreak paste preview print save searchreplace spellchecker tabfocus table template textcolor visualblocks visualchars wordcount']export default plugins5、toolbar.js
// Here is a list of the toolbar
// Detail list see https://www.tinymce.com/docs/advanced/editor-control-identifiers/#toolbarcontrolsconst toolbar = ['searchreplace bold italic underline strikethrough alignleft aligncenter alignright outdent indent blockquote undo redo removeformat subscript superscript code codesample hr bullist numlist link image charmap preview anchor pagebreak insertdatetime media table emoticons forecolor backcolor fullscreen','formatselect fontselect fontsizeselect'
]export default toolbar四、使用Tinymce组件
<template><TinyMceref="tiny"v-model="mdlValue.fullText":toolbar="toolbar"height="400px":menubar="''"></TinyMce>
</template>
<script>
import TinyMce from '../Tinymce/index'
export default {components:{TinyMce },data(){toolbar: ['searchreplace bold italic underline strikethrough alignleft aligncenter alignright outdent indent blockquote undo redo removeformat subscript superscript code codesample hr bullist numlist link image charmap preview insertdatetime emoticons forecolor backcolor','formatselect fontselect fontsizeselect'],}
}
</script>
五、业务逻辑实现
1、添加页面只读模式，解决方案（readonly: true）：
通过查文档可以知道 readonly: true 可以配置Tinymce是否只读，然后把他封装到我们的组件里
- a、在组件中添加props
- b、在组件初始化的时候添加该配置
- c、使用组件时传参
2、数据处理：传数据给后端需要进行base64加密，但是会把标签尖括号变成中文，导致回显时错误，解决方案：
- a、保存时转码之后再加密：
this.fullText = Base64.encode(this.fullText.replace(/</g, '<').replace(/>/g,'>'))
- b、回显时解密再转码
this.fullText = Base64.decode(data.fullText).replace(/</g, '<').replace(/>/g, '>'))
3、打开页面时会出现Tinymce还未实例化的情况，页面展示空白，解决方案：
-
a、给Tinymce组件绑定**
key** 值
-
b、在使用
Tinymce组件的页面的mouted去实例化
