Secondary Button
The 💠component responsible for the Telegram Mini Apps Secondary Button.
Checking Support
To check if the Secondary Button is supported by the current Telegram Mini Apps version, use the isSupported
method:
import { secondaryButton } from '@telegram-apps/sdk';
secondaryButton.isSupported(); // boolean
import { isSecondaryButtonSupported } from '@telegram-apps/sdk';
isSecondaryButtonSupported(); // boolean
Mounting
Before using this component, it is necessary to mount it to work with properly configured properties. To do so, use the mount
method. It will update the isMounted
signal property.
import { secondaryButton } from '@telegram-apps/sdk';
secondaryButton.mount();
secondaryButton.isMounted(); // true
import {
mountSecondaryButton,
isSecondaryButtonMounted,
} from '@telegram-apps/sdk';
mountSecondaryButton();
isSecondaryButtonMounted(); // true
To unmount, use the unmount
method:
secondaryButton.unmount();
secondaryButton.isMounted(); // false
import {
unmountSecondaryButton,
isSecondaryButtonMounted,
} from '@telegram-apps/sdk';
unmountSecondaryButton();
isSecondaryButtonMounted(); // false
WARNING
This component's properties depend on values from the Mini App and Theme Params components. Specifically, the Secondary Button uses the Mini App's bottomBarBgColor
and some of the Theme Params colors. Make sure to mount these components before using the Secondary Button.
Settings Properties
To update the button properties, use the setParams
method. It accepts an object with optional properties, each responsible for its own button trait.
In turn, calling this method updates such signals as backgroundColor
, hasShineEffect
, isVisible
, isEnabled
, isLoaderVisible
, position
, state
, textColor
and text
.
secondaryButton.setParams({
backgroundColor: '#000000',
hasShineEffect: true,
isEnabled: true,
isLoaderVisible: true,
isVisible: true,
position: 'top',
text: 'My text',
textColor: '#ffffff'
});
secondaryButton.backgroundColor(); // '#000000'
secondaryButton.hasShineEffect(); // true
secondaryButton.isEnabled(); // true
secondaryButton.isLoaderVisible(); // true
secondaryButton.isVisible(); // true
secondaryButton.position(); // 'top'
secondaryButton.text(); // 'My text'
secondaryButton.textColor(); // '#ffffff'
secondaryButton.state();
// {
// backgroundColor: '#000000',
// hasShineEffect: true,
// isActive: true,
// isLoaderVisible: true,
// isVisible: true,
// position: 'top',
// text: 'My text',
// textColor: '#ffffff'
// }
import {
setSecondaryButtonParams,
secondaryButtonBackgroundColor,
secondaryButtonHasShineEffect,
isSecondaryButtonVisible,
isSecondaryButtonEnabled,
isSecondaryButtonLoaderVisible,
secondaryButtonState,
secondaryButtonTextColor,
secondaryButtonText,
secondaryButtonPosition,
} from '@telegram-apps/sdk';
setSecondaryButtonParams({
backgroundColor: '#000000',
hasShineEffect: true,
isEnabled: true,
isLoaderVisible: true,
isVisible: true,
position: 'top',
text: 'My text',
textColor: '#ffffff'
});
secondaryButtonBackgroundColor(); // '#000000'
secondaryButtonHasShineEffect(); // true
isSecondaryButtonEnabled(); // true
isSecondaryButtonLoaderVisible(); // true
isSecondaryButtonVisible(); // true
secondaryButtonPosition(); // 'top'
secondaryButtonText(); // 'My text'
secondaryButtonTextColor(); // '#ffffff'
secondaryButtonState();
// {
// backgroundColor: '#000000',
// hasShineEffect: true,
// isActive: true,
// isLoaderVisible: true,
// isVisible: true,
// position: 'top',
// text: 'My text',
// textColor: '#ffffff'
// }
Tracking Click
To add a button click listener, use the onClick
method. It returns a function to remove the bound listener. Alternatively, you can use the offClick
method.
function listener() {
console.log('Clicked!');
}
const offClick = secondaryButton.onClick(listener);
offClick();
// or
secondaryButton.onClick(listener);
secondaryButton.offClick(listener);
import {
onSecondaryButtonClick,
offSecondaryButtonClick,
} from '@telegram-apps/sdk';
function listener() {
console.log('Clicked!');
}
const offClick = onSecondaryButtonClick(listener);
offClick();
// or
onSecondaryButtonClick(listener);
offSecondaryButtonClick(listener);
