Question

我正在尝试将daysLeft变量传递给Google跟踪代码管理器数据层，但它无法正常工作。如果我使用这个;

 var newname = 'daysLeft';

它会触发标记，但在报告中显示为daysLeft。如果我尝试使用

触发标记

 var newname = daysLeft;

标签不起作用。

        <script type="text/javascript">
    var today = new Date(); // Get todays date.
    var bookedDate = new Date('June 29, 2014'); // Fill this with the date of the booking in this format - June 29, 2013.
    var msPerDay = 24 * 60 * 60 * 1000 ; // Work out the number of milliseconds in a day.
    var timeLeft = (bookedDate.getTime() - today.getTime()); // Booked date minus todays tate, returned in milliseconds.
    var e_daysLeft = timeLeft / msPerDay; // Divide millieseconds left untill booking by the number of milliseconds in a day.
    var daysLeft = Math.floor(e_daysLeft); // Round the total down to the nearest integer.

    var newname = daysLeft;

    dataLayer = [{'event' : 'newname' }];

Answer 1

由于某种原因，dataLayer不会传递整数。

我必须先用

将其转换为字符串

daysLeft.toString();

为什么变量未传递到Google跟踪代码管理器的数据层
