The following code adds a simple Button to your page.

jQuery
HTML
JavaScript
<div id="buttonContainer"></div>
$(function () {
    $("#buttonContainer").dxButton({
        text: "OK",
        onClick: function (e) { 
            DevExpress.ui.notify("The OK button was clicked");
        }
    });
});
Angular
HTML
TypeScript
<dx-button
    text="OK"
    (onClick)="okClicked($event)">
</dx-button>
import { DxButtonModule } from "devextreme-angular";
import notify from "devextreme/ui/notify";
// ...
export class AppComponent {
    okClicked (e) {
        notify("The OK button was clicked")
    }
}
@NgModule({
    imports: [
        // ...
        DxButtonModule
    ],
    // ...
})
Vue
<template>
    <dx-button
        text="Click me"
        @click="okClicked" />
</template>
<script>
import DxButton from "devextreme-vue/button";
import notify from "devextreme/ui/notify";

export default {
    components: {
        DxButton
    },
    methods: {
        okClicked: function(e) {
            notify("The OK button was clicked");
        }
    }
}
</script>
React
import React from 'react';
import { Button } from 'devextreme-react/button';
import notify from 'devextreme/ui/notify';

class App extends React.Component {
    render() {
        return (
            <Button
                text="OK"
                onClick={this.okClicked}
            />
        );
    }

    okClicked(e) {
        notify('The OK button was clicked');
    }
}

export default App;

In the previous code, the click event is handled using the onClick option. Alternatively, you can attach one or several handlers to this event using the on(eventName, eventHandler) method. This approach is more typical of jQuery.

JavaScript
var clickHandler1 = function (e) {
    // First handler of the "click" event
};

var clickHandler2 = function (e) {
    // Second handler of the "click" event
};

$("#buttonContainer").dxButton("instance")
    .on("click", clickHandler1)
    .on("click", clickHandler2);

The appearance of the Button is predefined by its type. Find more on this and other properties that impact the widget appearance in the Customize the Appearance article.
