History in Vue Document editor component
11 Jun 20242 minutes to read
Document Editor tracks the history of all editing actions done in the document, which allows undo and redo functionality.
Enable or disable history
Inject the EditorHistory
module in your application to provide history preservation functionality for DocumentEditor
. Refer to the following code example.
<template>
<div id="app">
<ejs-documenteditor ref="documenteditor" :enableEditor='true' :isReadOnly='false' :enableEditorHistory='true'
style="width: 100%;height: 100%;"></ejs-documenteditor>
</div>
</template>
<script setup>
import { DocumentEditorComponent as EjsDocumenteditor, Editor, Selection, EditorHistory } from '@syncfusion/ej2-vue-documenteditor';
import { provide } from 'vue';
provide('DocumentEditor', [Editor, Selection, EditorHistory]);
</script>
<style>
@import "../node_modules/@syncfusion/ej2-vue-documenteditor/styles/material.css";
</style>
<template>
<div id="app">
<ejs-documenteditor ref="documenteditor" :enableEditor='true' :isReadOnly='false' :enableEditorHistory='true'
style="width: 100%;height: 100%;"></ejs-documenteditor>
</div>
</template>
<script>
import { DocumentEditorComponent, Editor, Selection, EditorHistory } from '@syncfusion/ej2-vue-documenteditor';
export default {
components: {
'ejs-documenteditor': DocumentEditorComponent
},
data: function () {
return {
};
},
provide: {
DocumentEditor: [Editor, Selection, EditorHistory]
}
}
</script>
<style>
@import "../node_modules/@syncfusion/ej2-vue-documenteditor/styles/material.css";
</style>
You can enable or disable history preservation for a Document Editor instance any time using the enableEditorHistory
property. Refer to the following sample code.
this.$refs.documenteditor.enableEditorHistory = false;
Undo and redo
You can perform undo and redo by CTRL+Z
and CTRL+Y
keyboard shortcuts. Document Editor exposes API to do it programmatically.
To undo the last editing operation in Document Editor, refer to the following sample code.
this.$refs.documenteditor.ej2Instances.editorHistory.undo();
To redo the last undone action, refer to the following code example.
this.$refs.documenteditor.ej2Instances.editorHistory.redo();
Stack size
History of editing actions will be maintained in stack, so that the last item will be reverted first. By default, Document Editor limits the size of undo and redo stacks to 500 each respectively. However, you can customize this limit. Refer to the following sample code.
this.$refs.documenteditor.ej2Instances.editorHistory.undoLimit = 400;
this.$refs.documenteditor.ej2Instances.editorHistory.redoLimit = 400;
