Segmentation

JS segmentation library for split tests

Source JavaScript code

Features

Assigns a visitor to one of the specified segments
The maximum number of segments is 26, like the letters in the Latin alphabet from A to Z
A visitor's belonging to a segment can be specified and can last for a session or a specified number of days

Method

/**
 * Get segment
 * @params {segments_number {integer}, prefix {string}, days {integer}}
 * @returns {string}
*/

segmab({params}, callback);

Parameters

Name	Type	Description
segments_number	interger	Number of segments (from 2 to 26)
prefix	string	Prefix to use several tests at the same time
days	integer	Segment's lifetime (if zero, the segment will be assigned for the duration of the browser session)

Usage

For example, three segments with the prefix "myprefix" were defined. And the segmentation script itself is connected to the "head" as a file.

<!DOCTYPE html>
<html>
    <head>
        <script src="js/segmentator.min.js"></script>
    </head>
    <body>
        ...
    </body>
</html>

Getting the segment value into an external variable:

const segment = segmab({segments_number: 3, prefix: "myprefix", days: 0});
switch(segment) {
    case 'A':
        // something for the segment "A" visitors
        break;
    case 'B':
        // something for the segment "B" visitors
        break;
    case 'C':
        // something for the segment "C" visitors
        break;
    default:
        // if the segment value has been reset
}

Using callback function. For example, to send a segment to Google Analytics:

segmab({segments_number: 3, prefix: "myprefix", days: 0}, segment => {
    ga("set", "dimension1", segment);
});
