google-analytics - cxApi.cxApi.getChosenVariation()仅返回cxApi.NO_CHOSEN_VARIATION

我执行以下操作-（XXXXX代表我的实验ID），如此处所述-https://developers.google.com/analytics/devguides/collection/gajs/experiments#cxjs-load

<!-- Google analytics Experiment-->
        <script src="//www.google-analytics.com/cx/api.js?experiment=XXXXX"></script>

<script>
   var variationExperiment = cxApi.chooseVariation('XXXXX');
   cxApi.setChosenVariation(variationExperiment,'XXXXX');
   console.log(variationExperiment); // gives 0 or 1 according the google decision
   console.log(cxApi.getChosenVariation('XXXXX')); // always returns -1 , mean cxApi.NO_CHOSEN_VARIATION
</script>

即使我以前做过console.log(cxApi.getChosenVariation('XXXXX'))，-1也只返回cxApi.setChosenVariation(variationExperiment,'XXXXX')。

这说明什么？我的google-analytics加载是否失败？

最佳答案

choiceVariation不允许使用任何参数。它使用脚本加载中的实验。
