Properties

currentConversation
: ConversationData | null

The conversation currently shown in the UI.

This field is null when the UI does not currently show a conversation (eg because null was passed to select or the selected conversation could not be found).

messageField
: MessageField

Encapsulates the message entry field tied to the currently selected conversation.

createHtmlPanel

chatbox.createHtmlPanel(options): Promise<HtmlPanel>
Puts custom HTML just above the message field.

Using HTML Panels, you can extend TalkJS UIs to have anything from credit card payments to lead collection forms, or, for instance, to show the product details of a marketplace transaction between your users. See our HTMLPanels documentation for more info.

Parameters

interface HtmlPanelOptions
conversation (optional)
: Conversation | ConversationBuilder | string

Either a Conversation object (as returned from getOrCreateConversation) or the id field of a conversation (which you may have stored in your database). If given the HTML panel called will only show up for that conversation.

height (optional)
: number

Optional, defaults to 100 (px).

show (optional)
: boolean

Optional, defaults to true. Set false if you don't want the HTML panel to be shown after createHtmlPanel is called. You can change the visibility of the HTML panels by calling .hide() or .show() on the HtmlPanel instance returned by createHtmlPanel's promise.

url
: string

Required. URL you want to load inside the HTML panel. Url can be absolute ("https://www.example.com/register-form.html") or relative ("register-form.html"). We recommend using same origin pages to have better control of the page. Learn more about HTML Panels and same origin pages here.

Returns

Promise<HtmlPanel>

destroy

chatbox.destroy()
Destroys the chatbox and removes it from the DOM

Destroys the chatbox, removes it from the DOM and removes all event listeners it has running. Call this before removing the chatbox container from the DOM.

Parameters

None.

Returns

void

mount

chatbox.mount(container): Promise<void>
Renders the Chatbox UI inside a DOM element on your page.

The container element specified by container must either be a DOM Element (as returned by e.g. document.getElementById) or a JQuery object with a single element.

Parameters

container
: HTMLElement | null

Returns

Promise<void>

onBlur

chatbox.onBlur(handler): Subscription
Triggers when focus moves out of the chat UI.

Emits an event when the user clicks/taps anywhere outside the chat UI.

Parameters

handler
: () => void

Returns

Subscription

onCustomMessageAction

chatbox.onCustomMessageAction(action, handler): Subscription
Triggers when a user launches a custom action within the TalkJS UI.

To set up a custom action, you need to create it in the role editor. If an action is allowed on a particular message, it'll show up in that message's action menu. The name you specify when setting up the action, is also the name you should pass in here (case sensitive). The event you get contains information about the message on which the action was called, including its ID, so you can look it up later via our REST API.

Parameters

action
: string

the action you want to listen for

handler
: (event: MessageActionEvent) => void

the handler to be called

Returns

Subscription

a subscription you can use to unsubscribe.

onFocus

chatbox.onFocus(handler): Subscription
Triggers when the chat UI is focussed.

Parameters

handler
: () => void

Returns

Subscription

onKeydown

chatbox.onKeydown(handler): Subscription
Triggers a KeyEvent when the user presses a key.

See onKeyup for more details.

Parameters

handler
: (event: KeyEvent) => void

Returns

Subscription

onKeyup

chatbox.onKeyup(handler): Subscription
Triggers a KeyEvent when the user releases a key.

This event is only emitted when ChatboxOptions​.captureKeyboardEvents is enabled. In that case, it is emitted for every keypress, including regular letters typed into text fields.

Note that there's a notorious system limitation on macOS: metaKey is not set in keyup events when hitting keystrokes (eg Cmd+p). Consider using onKeydown if you need to support Cmd.

event.isInputFocused is true when a TalkJS input area is focused (eg the message field, the search box, or adjacent buttons). When this is the case, keypresses are likely to cause changes inside the chat UI. We recommend that you discard these events except when implementing global shortcuts that should take effect regardless of whether the user is typing a message or otherwise interacting with the chat UI using the keyboard.

Note: by design, the TalkJS UI does not handle special multi-key shortcuts other than those provided by the user's device (eg ctrl+v for paste). This means that it is usually safe to assign special behavior to unused keyboard shortcuts with one or more modifier keys (like alt, shift or ctrl), even when isInputFocused is true.

All other event fields are the same as the corresponding fields in the browser's KeyboardEvent.

Example

myChatbox.onKeyup(event => {
if(event.shiftKey || event.altKey || event.metaKey) {
return;
}
// let the 1 key switch to our app's main panel, except if the user is typing
if(!event.isInputFocused && event.key === "1") {
myApp.selectMainPanel();
}
// quit if the user hits ctrl+q, irrespective of whether they're typing.
if(event.ctrlKey && event.key === "q") {
myApp.quit();
}
});

Parameters

handler
: (event: KeyEvent) => void

Returns

Subscription

onSendMessage

chatbox.onSendMessage(handler): Subscription
Triggers when the user sends a message using the TalkJS UI

Parameters

handler
: (event: SendMessageEvent) => void

Returns

Subscription

onTranslationToggled

chatbox.onTranslationToggled(handler): Subscription
Triggers when the user toggles message translation in the TalkJS UI.

Parameters

handler
: (event: TranslationToggledEvent) => void

Returns

Subscription

select

This method has 2 overloads
chatbox.select(conversation)
Switches the active conversation the conversation.

conversation can be either a ConversationBuilder object or a TalkJS conversation id. Passing null means that the conversation will be de-selected in the UI and the message list will disappear. Passing undefined means that the last conversation (or "no chats yet" page if there are no other conversations) will be rendered in the message list component.

Parameters

conversation
: string | Conversation | ConversationBuilder | null | undefined

Returns

void
chatbox.select(conversation, params)
Switches the active conversation the conversation.

conversation can be either a ConversationBuilder object or a TalkJS conversation id. Passing null means that the conversation will be de-selected in the UI and the message list will disappear. Passing undefined means that the last conversation (or "no chats yet" page if there are no other conversations) will be rendered in the message list component.

Parameters

conversation
: string | Conversation | ConversationBuilder | null | undefined
params (optional)
: { asGuest?: boolean }

Selection parameters. asGuest can be used to select the conversation as a guest, with limited functions

Returns

void

sendFile

chatbox.sendFile(file): Promise<void>
Upload a file attachment to the currently active conversation.

The behaviour of this method is similar to if the user clicked the attachment button, in that the confirmation dialog is shown to the user.

Ensure that the File object's name property has an appropriate file extension.

Parameters

file
: File

The File object to be uploaded.

Returns

Promise<void>

sendLocation

chatbox.sendLocation(): Promise<void>
Send the user's current location to the currently active conversation.

The behaviour of this method is identical to the user clicking the location button in message field i.e the confirmation dialog is shown.

Note: If the user had not previously granted location access to your website, calling this method will trigger the browser's popup asking them for permission to access their location. The user's location will only be shared if they allow.

Parameters

None.

Returns

Promise<void>

setHighlightedWords

chatbox.setHighlightedWords(words)
Highlights certain words in messages

The TalkJS search feature includes the ability to highlight certain words in messages. Call this method to highlight certain words without having the user invoke the search feature. Call again with an empty array to disable highlighting.

Note: like the search feature, this option only works on the Growth plan and up.

Also see ChatboxOptions​.highlightedWords

Parameters

words
: string[]

Returns

void

setMessageFilter

chatbox.setMessageFilter(filter)
Used to control which messages are shown in the message list

Lets you filter messages depending on a type, origin or custom message attributes.

Note: Messages are only filtered in the message list. The inbox UI's conversation feed will always show the last message sent to the conversation, regardless of the message filter set.

See MessagePredicate for all available options.

Example

// only show messages sent by users with role "admin"
chatbox.setMessageFilter({
sender: {
role: ["==", "admin"],
}
});

Parameters

A predicate object that controls which messages are shown.

Returns

void

setPresence

chatbox.setPresence(params)
Sets metadata for the current session.

Parameters

params
: { visible?: boolean custom?: {[key: string]: string }}

Object with presence parameters.

- visible manually sets the information about the visibility of TalkJS. This is useful when TalkJS is hidden with CSS. TalkJS will assume that UIs marked visible: false cannot be seen, and thus messages arriving on this UI will not be marked as read until you set visible to true again.

- custom is an additional parameter to store the custom fields, that you may want to use in the REST API call.

Returns

void

setTranslationEnabledDefault

chatbox.setTranslationEnabledDefault(boolean | "auto")
Enable/disable translation by default.

This setting is applied to any conversation for which you haven't set a specific value.

Parameters

enabled
: boolean | "auto"

Whether conversations should be translated by default or not. Pass "auto" to enable translation for conversations with users with different locales.

Returns

void

setTranslationEnabledForConversation

chatbox.setTranslationEnabledForConversation(conversation, enabled)
Enable or disable translation for a conversation.

Parameters

conversation
: string | ConversationBuilder

The conversation for which this should be set. If not specified, the setting will be applied to the currently selected conversation.

enabled
: boolean

Whether translation should be enabled

Returns

void
