Negotiate Button

The lens-negotiate-button component allows users to initiate a data request. It becomes active when one or more (site/data sources) are selected. Depending on the configuration, it either dispatches a general event or starts a negotiation through the BBMRI-ERIC Negotiator service. The button is disabled by default when no data source is selected. It fires a global lens-negotiate-triggered event when clicked.

Optionally integrates with the BBMRI-ERIC Negotiator when type is set to "Negotiator".

Props

Prop	Type	Default	Description
`title`	`string`	`"Request Data"`	The label shown on the button.
`type`	`string`	`""`	Determines the negotiation behavior. Use `"Negotiator"` to enable integration with BBMRI-ERIC.

Behavior

The button is disabled when no data sources are selected (datarequestsStore is empty).

Clicking the button always triggers a global browser event:

window.dispatchEvent(new CustomEvent("lens-negotiate-triggered"));

If type is "Negotiator", the internal bbmriNegotiate() function is also called, passing the current data request list.

Usage

<lens-negotiate-button type="Negotiator"></lens-negotiate-button>

Or with a custom label:

<lens-negotiate-button
    type="Custom"
    title="Start Request"
></lens-negotiate-button>
