jQuery Popup - Keyboard Support

An end user can use the following keys to interact with the UI component.

Key Action
↑ → ↓ ← Drags the popup when it is focused and dragEnabled is true.
Esc Closes the popup.

You can implement a custom handler for a key using the registerKeyHandler(key, handler) method.

jQuery
JavaScript
function registerKeyHandlers () {
    const popup = $("#popupContainer").dxPopup("instance");
    popup.registerKeyHandler("backspace", function(e) {
        // The argument "e" contains information on the event
    });
    popup.registerKeyHandler("space", function(e) {
        // ...
    });
}
Angular
TypeScript
import { ..., ViewChild, AfterViewInit } from '@angular/core';
import { DxPopupModule, DxPopupComponent } from 'devextreme-angular';
// ...
export class AppComponent implements AfterViewInit {
    @ViewChild(DxPopupComponent, { static: false }) popup: DxPopupComponent;
    // Prior to Angular 8
    // @ViewChild(DxPopupComponent) popup: DxPopupComponent;

    ngAfterViewInit () {
        this.popup.instance.registerKeyHandler('backspace', function(e) {
            // The argument "e" contains information on the event
        });
        this.popup.instance.registerKeyHandler('space', function(e) {
            // ...
        });
    }
}
@NgModule({
    imports: [
        // ...
        DxPopupModule
    ],
    // ...
})
Vue
<template>
    <DxPopup :ref="myPopupRef" />
</template>
<script>
import 'devextreme/dist/css/dx.common.css';
import 'devextreme/dist/css/dx.light.css';

import DxPopup from 'devextreme-vue/popup';

const myPopupRef = 'my-popup';

export default {
    components: {
        DxPopup
    },
    data() {
        return {
            myPopupRef
        }
    },
    computed: {
        popup: function() {
            return this.$refs[myPopupRef].instance;
        }
    },
    mounted: function() {
        this.popup.registerKeyHandler('backspace', function(e) {
            // The argument "e" contains information on the event
        });
        this.popup.registerKeyHandler('space', function(e) {
            // ...
        });
    }
}

React
App.js
import React from 'react';

    }

    render() {
        return (
            <Popup ref={this.popupRef} />
        );
    }
