API Reference

Data

Returns an object exposing the static data fields. These fields are the same for all visitors on all page loads until you modify your project.

📘

Note

optimizely.get("data") is a performance-intensive operation; as such you should use it sparingly. For example, if you need to get multiple pieces of data in the same function, call it once and reuse that reference:

var data = optimizely.get('data');
var experiment = data.experiments[myExperimentId];
var firstAudience = data.audiences[experiment.audienceIds[0]];

Syntax

data = window["optimizely"].get("data");

Parameters

ParameterChild AttributeDescription
data
string
N/AThe argument indicating to get data information. Required.

Description

A function to get the data object. The data object contains the fields of the objects you've created using the Optimizely UI or REST API. For example, if you create a new experiment using an audience, page and event, then you can expect to find all of those objects in the data object that's returned from this function.
