Quill modules and the API you can use to customize them are described in the Modules documentation section. For example, the History module, which handles the undo and redo operations, can be customized as follows:
jQuery
$(function() { $("#htmlEditorContainer").dxHtmlEditor({ // ... customizeModules: function(config) { config.history = { delay: 0, maxStack: 5000 }; } }); });
Angular
<dx-html-editor ... [customizeModules]="customizeQuillModules"> </dx-html-editor>
import { Component } from '@angular/core'; @Component({ selector: 'app-root', templateUrl: './app.component.html', styleUrls: ['./app.component.css'] }) export class AppComponent { customizeQuillModules(config) { config.history = { delay: 0, maxStack: 5000 }; } }
import { BrowserModule } from '@angular/platform-browser'; import { NgModule } from '@angular/core'; import { AppComponent } from './app.component'; import { DxHtmlEditorModule } from 'devextreme-angular'; @NgModule({ declarations: [ AppComponent ], imports: [ BrowserModule, DxHtmlEditorModule ], providers: [ ], bootstrap: [AppComponent] }) export class AppModule { }
Vue
<template> <DxHtmlEditor ... :customize-modules="customizeQuillModules" /> </template> <script> import 'devextreme/dist/css/dx.common.css'; import 'devextreme/dist/css/dx.light.css'; import DxHtmlEditor from 'devextreme-vue/html-editor'; export default { components: { DxHtmlEditor }, methods: { customizeQuillModules(config) { config.history = { delay: 0, maxStack: 5000 }; } } } </script>
React
import React from 'react'; import 'devextreme/dist/css/dx.common.css'; import 'devextreme/dist/css/dx.light.css'; import HtmlEditor from 'devextreme-react/html-editor'; class App extends React.Component { render() { return ( <HtmlEditor ... customizeModules={this.customizeQuillModules} /> ); } customizeQuillModules(config) { config.history = { delay: 0, maxStack: 5000 }; } } export default App;
If 3rd-party modules are used in the HtmlEditor, refer to their documentation for information on the API.
