Coveo Breadcrumb Component (CoveoBreadcrumb)

The Breadcrumb component displays a summary of the currently active query filters.

For example, when the user selects a Facet value, the breadcrumbs display this value.

The active filters are obtained by the component by firing an event in the Breadcrumb component.

All other components having an active state can react to this event by providing custom bits of HTML to display inside the breadcrumbs.

Thus, it is possible to easily extend the Breadcrumb component using custom code to display information about custom states and filters.

See BreadcrumbEvents for the list of events and parameters sent when a Breadcrumb component is populated.

    Also triggers a new query and logs the breadcrumbResetAll event in the usage analytics.

    Returns void

debugInfo

  • debugInfo(): any

disable

  • disable(): void
  • Disable the component. Normally this means that the component will not execute handlers for the framework events (query events, for example). Components are enabled by default on creation.

    Returns void

drawBreadcrumb

  • drawBreadcrumb(breadcrumbs: IBreadcrumbItem[]): void
  • Draws the specified breadcrumb items.

    Parameters

    • breadcrumbs: IBreadcrumbItem[]

      The breadcrumb items to draw.

    Returns void

enable

  • enable(): void
  • Enable the component. Normally this means that the component will execute handlers for the framework events (query events, for example). Components are enabled by default on creation.

    Returns void

getBindings

getBreadcrumbs

  • getBreadcrumbs(): IBreadcrumbItem[]

Static get

  • get(element: HTMLElement, componentClass?: any, noThrow?: boolean): BaseComponent
  • Get the bound component to the given HTMLElement. Throws an assert if the HTMLElement has no component bound, unless using the noThrow argument.
    If there is multiple component bound to the current HTMLElement, you must specify the component class.

    Parameters

    • element: HTMLElement

      HTMLElement for which to get the bound component.

    • Optional componentClass: any

      Optional component class. If the HTMLElement has multiple components bound, you must specify which one you are targeting.

    • Optional noThrow: boolean

      Boolean option to tell the method to not throw on error.

    Returns BaseComponent
