Tinymce官方提供了丰富的插件,足以知足关于通常富文本的需求,也能够经过进一步的配置,让其更符合实际的业务场景。可是,若是这还知足不了你的需求,想进一步的定制化呢?css
Tinymce提供了丰富的接口,用以编写自定义的插件。而且,官方的插件源码也很是清晰易懂,在写本身的插件的时候,能够作一个详细的参考。html
其实编写一个插件很简单,只须要作3件事情。node
由于公司这边的业务要求时,开发一个功能与微信公众号文章编辑器基本功能对称的富文本编辑器。而微信编辑器有一个设置行高的功能,Tinymce官方没有提供,虽然能够经过配置格式化样式进行简单的开发,但为了统一体验,就仿照微信编辑器在工具栏新增了一个能够设置行距的按钮。api
import Tinymce from 'tinymce'
Tinymce.PluginManager.add('lineheight', function (editor) {
// 执行方法
const actionFunction = function (editor, val) {
const value = val || editor.getParam('lineheight_default_value', 1.5)
editor.formatter.apply('lineheight', { value })
}
// 命令
editor.addCommand('mceLineHeight', function (ui, value) {
actionFunction(editor, value)
})
// toolbar 按钮 图标
editor.ui.registry.addIcon('lineheight', ` <svg xmlns="http://www.w3.org/2000/svg" width="24" height="24" viewBox="0 0 24 24"> <path d="M5,5 L19,5 L19,7 L5,7 L5,5 Z M13,9 L19,9 L19,11 L13,11 L13,9 Z M13,13 L19,13 L19,15 L13,15 L13,13 Z M5,17 L19,17 L19,19 L5,19 L5,17 Z M11.07,11.46 L8.91,9.84 L6.75,11.46 L5.79,10.18 L8.43,8.2 C8.71444444,7.98666667 9.10555556,7.98666667 9.39,8.2 L12.03,10.18 L11.07,11.46 Z M8.91,14.16 L11.07,12.54 L12.03,13.82 L9.39,15.8 C9.10555556,16.0133333 8.71444444,16.0133333 8.43,15.8 L5.79,13.82 L6.75,12.54 L8.91,14.16 Z" id="行间距"></path> </svg> `)
// toolbar 按钮功能
editor.ui.registry.addSplitButton('lineheight', {
tooltip: '行间距',
// 图标

// 初始化
onSetup (api) {
editor.formatter.register({
lineheight: {

fetch (callback) {
const items = [

这个插件只是对当前内容的一种格式化。比较简单。微信
插件必定要在tinymce
引入以后,实例初始化以前引入。若是插件出现重名,会优先使用本身项目中的插件。换言之,初始化的时候,会先找已注册的插件,没有找到的话,会根据配置,去相对路径取插件文件。app
import Tinymce from 'tinymce'
import './plugins/lineheight'
Tinymce.init({
selector: '.textarea',
plugins: ['lineheight']
})

由于编辑器自带的插件不能知足业务需求,因此本身写了一个预览插件。cors

const Settings = {
getContentStyle (editor) {
return editor.getParam('content_style', '')

shouldUseContentCssCors (editor) {
return editor.getParam('content_css_cors', false, 'boolean')

getBodyId (editor) {
let bodyId = editor.settings.body_id || 'tinymce'

这个插件根据编辑器官方的预览插件改写而成,定制化了一些样式。如前所述,由于与官方插件重名,因此官方的插件文件将再也不会被加载。这个插件比行高插件稍微复杂了点,可是它没有对内容进行改动。dom
