【VUE+ELEMENT-UI富文本tinymce】
嵌套富文本编辑器tinymce
- 安装tinymce
- 添加组件tinymce
安装tinymce
npm install tinymce -S
npm install @tinymce/tinymce-vue -S
添加组件tinymce
我们将tinymce做成组件形式供所有有需求的页面使用
目录结构如下：
- 在vue项目中src/components目录下新建目录Tinymce组件目录以及在Tinymce目录下创建文本域所需组件目录components
- 新建动态加载脚本文件dynamicLoadScript.js，插件文件plugins.js，工具栏文件toolbar.js，文件上传组件EditorImage.vue和富文本编辑框组件index.vue
- 文件内容如下：
dynamicLoadScript.js
let callbacks = []
function loadedTinymce() {
// to fixed https://github.com/PanJiaChen/vue-element-admin/issues/2144
// check is successfully downloaded script
return 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 = src
document.body.appendChild(script)
callbacks.push(cb)
const onEnd = 'onload' in script ? stdOnEnd : ieOnEnd
onEnd(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 others
this.onerror = this.onload = null
for (const cb of callbacks) {
cb(null, script)
}
callbacks = null
}
script.onerror = function() {
this.onerror = this.onload = null
cb(new Error('Failed to load ' + src), script)
}
}
function ieOnEnd(script) {
script.onreadystatechange = function() {
if (this.readyState !== 'complete' && this.readyState !== 'loaded') return
this.onreadystatechange = null
for (const cb of callbacks) {
cb(null, script) // there is no way to catch loading errors in IE8
}
callbacks = null
}
}
}
export default dynamicLoadScript
plugins.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 textpattern visualblocks visualchars wordcount']
export default plugins
toolbar.js
// Here is a list of the toolbar
// Detail list see https://www.tinymce.com/docs/advanced/editor-control-identifiers/#toolbarcontrols
const 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']

至此tinymce文本域组件创建成功
- 页面引入文本域组件tinymce：
<tinymce ref="tinymce" :width="1000" :height="300" v-model="setMailForm.contentTemplate"></tinymce>
import Tinymce from '@/components/Tinymce'
export default {
components:{
Tinymce
},
data() {
return {
content: 'tinymce文本域内容赋值',
}
}
methods: {
setTinymceContent() {
this.$nextTick(() =>
this.$refs.tinymce.setContent(this.content)
);
}
}
}
