After we initialize Messages we have its initialized instance in variable (like messages variable in example above) with helpful methods and properties:

messages.paramsObject with passed initialization parameters
messages.elMessages container HTML element (<div class=”messages”>)
messages.$elDom7 element with messages HTML element
messages.messagesArray with messages
Methods
messages.showTyping(message)Show typing message indicator

  • message - object - parameters of message to add. Required.
  • method - string - (append or prepend) dictates to add new message in the end or in the beginning of messages container. Optional, if not specified, then it will add message depending on newMessagesFirst parameter
  • animate - boolean - (by default true) You may pass here false and message will be added immediately without any transiton and scrolling animation. Optional.
  • Method returns Messages instance

Messages Events

Messages will fire the following DOM events on messages element and events on app and messages instance:

DOM Events

EventTargetDescription
messages:beforedestroyMessages Element<div class=”messages”>Event will be triggered right before Messages instance will be destroyed

App and Messages Instance Events

Messages instance emits events on both self instance and app instance. App instance events has same names prefixed with messages.

EventTargetArgumentsDescription
beforeDestroymessages(messages)Event will be triggered right before Messages instance will be destroyed
messagesBeforeDestroyapp

Messages Auto Initialization

If you don’t need to use Messages API and your Messages is inside of the page and presented in DOM on moment of page initialization then it can be auto initialized with just adding additional messages-init class to messages element, and all required parameters can be passed using data- attributes:

  1. <div class="messages messages-init" data-new-messages-first="true">
  2.   ...
  3. </div>

Parameters that used in camelCase, for example newMessagesFirst, in data- attributes should be used in kebab-case as data-new-messages-first
