在另一个GTM JavaScript变量中返回GTM JavaScript变量(数组)的总和(Return total of a GTM JavaScript variable (array) in another GTM JavaScript variable)

这是我在这个网站上的第一个问题,我很好奇是否有人可以帮助我。 在Google跟踪代码管理器中,我尝试使用一些jQuery设置自定义JavaScript变量,该变量应返回特定数组中的所有产品价格的总量。

在下面的代码中,我返回增强型电子商务数据图层中的所有产品价格。 在GTM中,我将此变量称为“{{product price}}”。

function() {

var itemsInC = {{ecommerce.checkout.products}};

itemsincart = [];

for (var i = 0;i < itemsInC.length;i++) {

          priceincart.push(itemsInC[i].price);

    }

return priceincart;

}

上面的代码实际工作,例如返回一个值,如:['9.99','21 .95','34 .99']。

在第二段代码中,我尝试总结GTM变量“{{product price}}”中所有返回值的总和。 但是,下面的代码无法正常工作。 我怎样才能在下面的脚本中返回上面脚本的总值?

这是我迄今创建的:

function() {

    var total = $("{{product price}}").each(function() {

                0 += parseInt($(this).val(), 10);

    }

return total;

}

提前致谢!

亲切的问候,


This is my very first question on this website, I am curious if someone could help me out. In Google Tag Manager I tried to set up a custom JavaScript variable with some jQuery that should return the total amount of all product prices within a specific array.

In the code below I return all product prices within an Enhanced Ecommerce dataLayer. In GTM, I have called this variable "{{product price}}".

function() {

var itemsInC = {{ecommerce.checkout.products}};

itemsincart = [];

for (var i = 0;i < itemsInC.length;i++) {

          priceincart.push(itemsInC[i].price);

    }

return priceincart;

}

The code above actually works and for example returns a value like: ['9.99', '21.95', '34.99'].

In the second piece of code I try to sum up the total of all returned values in the GTM variable "{{product price}}". However, the code below doesn't work properly. How could I return the total value of the script above in the script below?

This is what I created so far:

function() {

    var total = $("{{product price}}").each(function() {

                0 += parseInt($(this).val(), 10);

    }

return total;

}

Thanks in advance!

Kind regards,

最满意答案

这是因为Heroku在严格模式之外使用的Node版本中尚不支持块范围声明( letconst )。

所以有两个选择:

  • 添加"use strict"; 在您的文件的开头
  • 使用var而不是let

That is because Block-scoped declarations (let, const) are not yet supported in the Node version Heroku is using outside of strict mode.

So two options:

  • Add "use strict"; at the beginning of your file
  • Use var and not let.
