访问先前存储的访客级自定义变量 [英] Access previously stored Visitor-level custom variable

问题描述

在Google Analytics中，访问者级别的自定义变量存储在Cookie中。

我只想将一些数据存储在GA自定义变量中之前没有数据存储在此插槽中，即从不覆盖访问者级自定义变量。

有没有什么办法可以做到这一点，无论是通过测试是否已经存储了一些数据，或者通过检索存储值？

没有 _getCustomVar ，但是任何方式，我可以做一些相当的事情，而不是黑客入我自己的cookie？

_getVisitorCustomVar（index）

例如：

  _gaq.push（function （）{
 var pageTracker = _gat._getTrackerByName（）; //获取默认的跟踪器
 var visitorCustomVar1Value = pageTracker._getVisitorCustomVar（1）; 
}）; 
  

它只适用于Visitor级别的自定义var，因为这是GA cookie中唯一存储的客户端大小 __ utmz 。但是，这正是你想要的我猜。

如果你想查看是否已经设置了非访客级定制变量，那么你需要当您将自定义var设置为可以稍后检索时，自己编写存储单独cookie的逻辑。但它应该是一个简单的事情，并且可能比侵入私有cookie更好。

In Google Analytics, Visitor-level custom variables are stored in cookies.

I'm looking to store some data in a GA custom variable only if no data has been stored in this slot before, i.e. never overwrite visitor-level custom variables.

Is there any way I can do that, either by testing whether some data has already been stored, or by retrieving the stored value?

There's no _getCustomVar, but is there any way I can do something equivalent without "hacking" into the cookies myself?

解决方案

There is _getVisitorCustomVar(index).

eg:

_gaq.push(function() {
  var pageTracker = _gat._getTrackerByName(); // Gets the default tracker.
  var visitorCustomVar1Value = pageTracker._getVisitorCustomVar(1);
});

It only works for Visitor level custom var because that's the only one stored client size in the GA cookie __utmz. But that's exactly what you are looking for I guess.

If you want to see if a non-visitor level custom var that has already been set, then you would need to write the logic yourself storing a separate cookie when you set the custom var to be able to retrieve later. But it should be a simple thing and probably better idea than hacking into proprietary cookies.
