Commands

Commands are instructions issued by the parent window to the iframed flipbook. Commands can be invoked by calling magic methods, which can be accessed directly from the API instance.

Overview

Commands are issued from the parent window (your website) to the JavaScript API. The API then relays the command via window.postMessage() to the iframed flipbook.

Flipbook-related commands

updateEventSettings

It is possible to dictate how the iframed flipbook should handle events when they have been triggered. The method accepts a single argument that is an object containing the following keys, which references events that the v2 Flipbook API listens to:

• onBasketClick
• onItemAdd

The keys should contain an object of the following format: { preventDefault: <boolean> }, where <boolean> is true or false. When preventDefault is set to true, the flipbook will skip the default action associated with each event. If set to false, the default action will be performed.

Event	Default action taking place in the flipbook
onBasketClick	Opens the shop basket
onItemAdd	Adds the item to the shop basket. Triggered by any enrichment that adds a shop item (e.g. shop variant menu).

An example use:

// Disable opening of shop basket AND adding shop items
iPaperAPI.updateEventSettings({
	onBasketClick: { preventDefault: true },
	onItemAdd: { preventDefault: true }
});

Publication-related commands

goToPage

Navigate to a specific page: the page number is to be provided as the one and only argument of the function. For example:

iPaperAPI.goToPage(4);

goToPreviousPage

Go to the previous spread (if flipbook has a spread-based layout), or the previous page (if flipbook has a page-based layout). This method accepts no arguments:

iPaperAPI.goToPreviousPage();

goToNextPage

Go to the next spread (if flipbook has a spread-based layout), or the next page (if flipbook has a page-based layout). This method accepts no arguments:

iPaperAPI.goToNextPage();

Shop-related commands

addItem

Programmatically adds a custom item to the basket. This method accepts a single argument, consisting of properties of the shop item entity.

Property	Type	Description
title	string	Shop item title
description	string	Shop item description
productID	string	Shop item product ID
originPage	number	Page number where the shop item is located
price	number	Shop item price
quantity	number	Number of items added

Example use:

iPaperAPI.addItem({
    title: 'My product',
    description: 'Product description',
    productID: 'PROD-25B',
    price: '29.95',
    originPage: 6,
    quantity: 1
});

Advanced use

If you are accustomed to the .trigger() regime (such as that implemented in JQuery), you can also use it as such:

iPaperAPI.trigger('goToPage', 4);

Refer to Event listeners and command triggers on the advanced usage page for a wholesome example.
