cxApi.cxApi.getChosenVariation（）仅返回cxApi.NO_CHOSEN_VARIATION

Question

我按照以下说明执行以下操作-（ XXXXX代表我的实验ID） XXXXX : //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>

即使我之前做了cxApi.setChosenVariation(variationExperiment,'XXXXX') console.log(cxApi.getChosenVariation('XXXXX'))仅返回-1 。

这说明什么？ 我的google-analytics加载是否失败？

Answer 1

choiceVariation不允许任何参数。 它使用脚本加载中的实验。
