Functions

This topic describes how Optimizely Web Experimentation's (fka Optimizely X) various functions differ from Optimizely Classic.

Activate

_Available in Optimizely Web Experimentation: Yes, but in a different format.

Classic format:

window["optimizely"].push(["activate"]);

Optimizely Web Experimentation format:

window["optimizely"].push({
  "type": "activate"
});

In Optimizely Classic, the activate function was used to activate all manually activated experiments. In Optimizely Web Experimentation, activation happens at the page level.

Due to the different nature of the activate function, the activate function as it was available in Optimizely Classic does not work for Optimizely Web Experimentation. Instead, there is a new function in Optimizely Web Experimentation for window["optimizely"].push({type: "activate"});. The function differs from the activate function in Optimizely Classic but has the same goal. The difference is that the entire Optimizely execution cycle is (re)activated.

You can read more about the new activate method here.

Activate a single experiment

Available in Optimizely Web Experimentation: Yes, but in a different format.

Classic format:

window["optimizely"].push(["activate", experimentId]);

Optimizely Web Experimentation format:

window["optimizely"].push({
  "type": "page",
  "pageName": "watchedVideo",
});

In Optimizely Classic, the activate function was used to activate one manually activated experiment. In Optimizely Web Experimentation, activation happens at the page level. By activating a page, all associated experiments and campaigns are activated.

In Optimizely Web Experimentation, you can manually activate a page with the Page function.

Activate SiteCatalyst with sVar

Available in Optimizely Web Experimentation: Yes

Classic format:

window["optimizely"].push(["activateSiteCatalyst", {"sVariable": mySVar}]);

Optimizely Web Experimentation format:
