DynamicPricing.js reference

Reference documentation for the DynamicPricing.js library
This page documents the scripts, element attributes and functions available in Digital River's browser-side DynamicPricing.js library.
For details on how to use this library with Prebuilt Checkout, refer to Setting up local pricing.

Local pricing script

On each html page that contains price elements, you must have a script with an id of DR-Dynamic-Pricing.
With the exception of the script's attributes, the following code must remain unaltered:
<script id="DR-Dynamic-Pricing">
(function () {
var s = document.createElement('script');
s.type = 'text/javascript';
s.async = true;
s.setAttribute('data-dr-apiKey', 'YOUR_PUBLIC_API_KEY')
// optional - defaults to 'DR-currencySelector'
s.setAttribute('data-dr-currency-selector', 'currency-selector');
// optional - defaults to browser language
s.setAttribute('data-dr-default-country', 'FR');
s.src = '';

Script attributes

In the local pricing script, the following attributes are configurable:


You're required to set data-dr-apiKey and the value you pass must be your public API key.


You can optionally set data-dr-currency-selector. If you do, a DOM element whose id is the same value as data-dr-currency-selector needs to be on the page.
The default value is DR-currencySelector.
For more details, refer to Specify a local pricing selector element.


You can use the optional data-dr-default-country attribute to help determine which country is selected by default when a page loads. By extension, this also determines the selected currency.
The value you pass must be a two-letter Alpha-2 country code as described in the ISO 3166 international standard.
When the page loads and the local pricing script executes, it first looks for the user's country in cookies, next in data-dr-default-country, and then in the browser's default language settings. If those searches aren't successful, your account's base country is used.
Once a value is located, DynamicPricing.js makes a call to determine that country's default currency. The local pricing selector's drop-down menus then display these country and currency values. Additionally, your price elements are denoted in this currency.

Local pricing selector

The local pricing selector allows customers to select a country-currency combination while shopping on your site.
The selector's country drop-down displays all of your supported countries.
When customers choose a different country, the selector's currency drop-down displays that country's default currency. If you set up your account so that all transactions in the selected country must be conducted in a default currency, then only that option is available. Otherwise, all the currencies saved to your account are presented as options.
To configure the local pricing selector, you'll need to (1) designate a DOM element and (2) apply a stylesheet.

Specify a local pricing selector element

You need to include a DOM element that renders the local pricing selector. The element can be added to header, footer, body, and other HTML tags.
The element's id must be (1) DR-currencySelector or (2) the value you assign data-dr-currency-selector.
If you don't set data-dr-currency-selector, then id of the selector element must be DR-currencySelector
<div id="DR-currencySelector">
If you set data-dr-currency-selector, then id of the selector element must be that same value.
s.setAttribute('data-dr-currency-selector', 'currency-selector');
<div id="currency-selector">

Style the local pricing selector

To style the local pricing selector, add the following link.
<link href="" rel="stylesheet"/>
Alternatively, you can override this stylesheet with your own.

Price elements

Each DOM element on your site that displays pricing information must have a data-dr-original-price attribute. These represent your base prices. Make sure the values you pass don't contain a currency symbol or any whitespaces.
<div data-dr-original-price="199.99"></div>
When populating your data-dr-original-price attributes, retrieve data from a price list that is associated with your account's base country and base currency.
To retrieve your base country and currency, pass your public API key in the header of a GET /dynamic-pricing/country-currency request.
Also, depending on your account's tax configurations, make sure that your data-dr-original-price values are either tax inclusive or tax exclusive. For details, contact your Digital River representative.
When the local pricing script executes or customers modify currency and/or country in the selector, DynamicPricing.js makes a call to get country-currency specific data, and then checks whether the country is both supported by Digital River and setup to allow variable pricing. If these conditions are met, DynamicPricing.js applies a conversion factor and a rounding function to each data-dr-original-price on the page, implements currency formatting rules and then displays the converted, formatted value in the DOM element's innerHTML and adds data-dr-converted-price and data-dr-formatted-price to the element's attributes.
<div class="price" data-dr-original-price="199" data-dr-currency="EUR" data-dr-country="FR" data-dr-converted-price="230.00" data-dr-formatted-price="230,00 €">230,00 €</div>

Getting country and currency

The local pricing script creates the digitalRiverPricing object which exposes getCountry() and getCurrency().


Call digitalRiverPricing.getCountry() to get the country that is selected in the local pricing selector.
The returned value is formatted as an Alpha-2 country code.


Call digitalRiverPricing.getCountry() to get the currency that is selected in the local pricing selector.
The returned value is formatted as a three-letter alphabetic code that conforms to the ISO 4217 standard.
