defaultOptions is a static method that the UI component class supports. The following code demonstrates how to specify default properties for all instances of the Tabs UI component in an application executed on the desktop.

jQuery

JavaScript

DevExpress.ui.dxTabs.defaultOptions({ 
    device: { deviceType: "desktop" },
    options: {
        // Here go the Tabs properties
    }
});

Angular

TypeScript

import Tabs, { Properties } from "devextreme/ui/tabs";
// ...
export class AppComponent {
    constructor () {
        Tabs.defaultOptions<Properties>({
            device: { deviceType: "desktop" },
            options: {
                // Here go the Tabs properties
            }
        });
    }
}

Vue

<template>
    <div>
        <DxTabs id="tabs1" />
        <DxTabs id="tabs2" />
    </div>
</template>
<script>
import DxTabs from "devextreme-vue/tabs";
import Tabs from "devextreme/ui/tabs";

Tabs.defaultOptions({
    device: { deviceType: "desktop" },
    options: {
        // Here go the Tabs properties
    }
});

export default {
    components: {
        DxTabs
    }
}
</script>

React

import dxTabs from "devextreme/ui/tabs";
import Tabs from "devextreme-react/tabs";

dxTabs.defaultOptions({
    device: { deviceType: "desktop" },
    options: {
        // Here go the Tabs properties
    }
});

export default function App() {
    return (
        <div>
            <Tabs id="tabs1" />
            <Tabs id="tabs2" />
        </div>
    )
}

You can also set rules for multiple device types:

jQuery

JavaScript

const devicesConfig = [
    { deviceType: 'desktop' },
    { deviceType: 'tablet' },
    { deviceType: 'phone' },
];

devicesConfig.forEach(deviceConfig => {
    DevExpress.ui.dxTabs.defaultOptions({ 
        device: deviceConfig,
        options: {
            // Here go the Tabs properties
        }
    });
});

Angular

TypeScript

import Tabs, { Properties } from "devextreme/ui/tabs";
// ...
export class AppComponent {
    constructor () {
        const devicesConfig = [
            { deviceType: 'desktop' },
            { deviceType: 'tablet' },
            { deviceType: 'phone' },
        ];

        devicesConfig.forEach(deviceConfig => {
            Tabs.defaultOptions<Properties>({
                device: deviceConfig,
                options: {
                    // Here go the Tabs properties
                }
            });
        });
    }
}

Vue

<template>
    <div>
        <DxTabs />
    </div>
</template>
<script>
import DxTabs from "devextreme-vue/tabs";
import Tabs from "devextreme/ui/tabs";

const devicesConfig = [
    { deviceType: 'desktop' },
    { deviceType: 'tablet' },
    { deviceType: 'phone' },
];

devicesConfig.forEach(deviceConfig => {
    Tabs.defaultOptions({
        device: deviceConfig,
        options: {
            // Here go the Tabs properties
        }
    });
});

export default {
    components: {
        DxTabs
    }
}
</script>

React

import dxTabs from "devextreme/ui/tabs";
import Tabs from "devextreme-react/tabs";

const devicesConfig = [
    { deviceType: 'desktop' },
    { deviceType: 'tablet' },
    { deviceType: 'phone' },
];

devicesConfig.forEach(deviceConfig => {
    dxTabs.defaultOptions({
        device: deviceConfig,
        options: {
            // Here go the Tabs properties
        }
    });
});

export default function App() {
    return (
        <div>
            <Tabs />
        </div>
    )
}

dispose()

Disposes of all the resources allocated to the Tabs instance.

jQuery

After calling this method, remove the DOM element associated with the UI component:

JavaScript

$("#myTabs").dxTabs("dispose");
$("#myTabs").remove();

Angular

Use conditional rendering instead of this method:

app.component.html

<dx-tabs ...
    *ngIf="condition">
</dx-tabs>

Vue

Use conditional rendering instead of this method:

App.vue

<template>
    <DxTabs ...
        v-if="condition">
    </DxTabs>
</template>

<script>
import DxTabs from 'devextreme-vue/tabs';

export default {
    components: {
        DxTabs
    }
}
</script>

React

Use conditional rendering instead of this method:

App.js

import React from 'react';

import Tabs from 'devextreme-react/tabs';

function DxTabs(props) {
    if (!props.shouldRender) {
        return null;
    }

    return (
        <Tabs ... >    
        </Tabs>
    );
}

class App extends React.Component {
    render() {
        return (
            <DxTabs shouldRender="condition" />
        );
    }
}
export default App;

Return Value:

HTMLElement | jQuery

An HTML element or a jQuery element when you use jQuery.

getInstance(element)

Gets the instance of a UI component found using its DOM node.

Parameters:

element:

Element

jQuery

The UI component's container.

Return Value:

Object

The UI component's instance.

getInstance is a static method that the UI component class supports. The following code demonstrates how to get the Tabs instance found in an element with the myTabs ID:

// Modular approach
import Tabs from "devextreme/ui/tabs";
...
let element = document.getElementById("myTabs");
let instance = Tabs.getInstance(element) as Tabs;

// Non-modular approach
let element = document.getElementById("myTabs");
let instance = DevExpress.ui.dxTabs.getInstance(element);
