JavaScript Loader (Deprecated)

WARNINGThe JavaScript loader is a deprecated method of integrating widgets on a website. The loader will continue to work, but you should use the Web Widget SDK instead.

Once you’ve generated a URL, you can pass that information on to a JavaScript loader provided by MX. This loader allows you to further configure your Connect Widget, including the size as well as all the supported configuration options, inside the config object. It also allows you to listen for event messages that indicate loading or a successful member creation.

WARNINGThe event messages handled by onEvent below allow partners to take action in their own codebase in response to events triggered within the Connect Widget’s UI. They are intended specifically to allow a partner’s code and the widget’s UI to work in concert over a single session, not to give canonical information on the state of a member or other information available by request to the appropriate endpoint, e.g., read member connection status.

Example

<script src="https://atrium.mx.com/connect.js"></script>
/**
 * The reference to "atrium" is a holdover from a legacy API.
 * Nevertheless, this is still the correct source for the widget loader
 * even in the context of the Platform API.
 */

<script>
var mxConnect = new window.MXConnect({
  id: "connect-widget",
  iframeTitle: "Connect",
  /**
   * Callback that for handling all events within Connect.
   * Only called in  ui_message_version 4 or higher.
   *
   * The events called here are the same events that come through post
   * messages.
   */
  onEvent: function (type, payload) {
    console.log("onEvent", type, payload);
  },
  targetOrigin: "*",
})
</script>
