Pattern Match

RTP provides a utility function that checks whether a pattern matches a string. The utility returns a match result synchronously and cannot be used asynchronously.

You must be a Web Personalization customer and have the RTP tag deployed on your site before using the User Context API.

Usage

rtp.checkPattern(check_against, pattern);

Examples

This example sets a custom variable at index 1 when the current page URL ends with “productA”.

if (rtp.checkPattern(window.location.href, '%productA')) {
    rtp('set', 'custom1', 'productA');
}

In the following example, the current URL path is ‘/products/productB’. The example checks whether the path contains “products” and then sets a custom variable.

var currentURLPath = '/products/productB';
if (rtp.checkPattern(currentURLPath, '%products%')) {
    rtp('set', 'custom1', 'products');
}
