Methods

closeApplication

async closeApplication(): Promise<void>

Closes the application slider.

fitWindow

async fitWindow(): Promise<any>

Sets the application frame size according to its content size.

resizeWindow

async resizeWindow(width: number, height: number): Promise<void>

Resizes the application frame to the specified width and height.

resizeWindowAuto

async resizeWindowAuto(
    appNode: null | HTMLElement = null,
    minHeight: number = 0,
    minWidth: number = 0
): Promise<void>

Automatically resizes the document.body of the application frame according to its content size.

getScrollSize

getScrollSize(): { scrollWidth: number, scrollHeight: number }

Returns the internal dimensions of the application frame.

scrollParentWindow

async scrollParentWindow(scroll: number): Promise<void>

Scrolls the parent window to the specified position.

reloadWindow

async reloadWindow(): Promise<void>

Reloads the application page.

setTitle

async setTitle(title: string): Promise<void>

Sets the application page title — the in-layout heading element (#pagetitle) that Bitrix24 renders around your app. It does not change the browser tab title.

The portal handles this command with BX.ajax.UpdatePageTitle(), which rewrites the #pagetitle element. It never calls BX.ajax.UpdateWindowTitle() (the function that assigns document.title), so the browser tab title stays untouched — regardless of the app's domain or placement mode.

To put a title into the browser tab, open the view as a slider with a bx24_title option (see slider.openSliderAppPage):

await $b24.slider.openSliderAppPage({ bx24_title: 'Q1 2025 — John Smith' })

For full, dynamic control of the browser tab title (e.g. telling apart several standalone browser tabs of your app), the app must own the top-level document — i.e. run as a standalone page outside the portal iframe, where you set document.title yourself.

imCallTo

async imCallTo(userId: number, isVideo: boolean = true): Promise<void>

Initiates a call through internal communication.

imPhoneTo

async imPhoneTo(phone: string): Promise<void>

Makes a call to the specified phone number.

imOpenMessenger

async imOpenMessenger(dialogId: number|'chat${number}'|'sg${number}'|'imol|${number}'|undefined): Promise<void>

Opens the messenger window.

imOpenHistory

async imOpenHistory(dialogId: number|'chat${number}'|'imol|${number}'): Promise<void>

Opens the message history window.
