Javascript:setInterval()函数中的变量的计数增加5 [英] Javascript: Increment count by 5 for a variable inside a setInterval() function

问题描述

我正在尝试使用 Google Analytics(分析)事件来跟踪时间在网站上的花费更为准确(无需依赖访问网站上另一个页面之间的时间间隔).我正在使用setInterval()连续每5秒触发一次GA.如何正确增加与GA事件数据一起发送所经过的秒数?

I'm trying to use Google Analytics events to track time spent on site more accurately (without relying on delta time between visits to another page on site). I'm using setInterval() to continuously trigger that GA even every 5 seconds. How do I properly increment seconds elapsed to send along with the GA event data?

  var count = 0;
  setInterval(function(){
    // increment "count" by 5 each time setInterval is run
    ga('send', 'event', 'time', 'tracking', 'seconds', count);
  }, 5000);

推荐答案

  var count = 0;
  setInterval(function(){
    // increment "count" by 5 each time setInterval is run
    count+=5; //is this what you need?
    ga('send', 'event', 'time', 'tracking', 'seconds', count);
  }, 5000);
