jquery gtm transfer time

Each website has its own unique operational needs and data tracking and analysis needs, so whether it is Google Tag Manager (Google Tag Manager, abbreviated as GTM) or jQuery, they are indispensable tools in the website optimization process. And today, we will teach you how to convert time format through jQuery GTM.

First of all, jQuery is an excellent JavaScript framework that can help website developers reduce the amount of code and improve efficiency during the development process. In this article, we will lead you to use jQuery method to solve the problem of time format conversion.

Whether it is to display time and date on a web page or to use timestamps as data tracking indicators in GTM, we need to standardize and convert the time format. Therefore, let's take a look at how to use jQuery and GTM to quickly convert time formats.

1. Common time formats

Before dealing with time formats, we must know some common time formats. The following are several common time formats:

1. yyyy-MM-dd：Year-Month-Day
2. yyyy/MM/dd：Year/Month/Day
3. HH:mm:ss：Hour:Minute:Second
4. yyyy-MM-dd HH:mm:ss：Year-Month-Day Hour:Minute:Second
5. yyyyMMddHHmmss：Year-month-Day-Hour-Minute-Second

If the website developer wants To display these times on a web page, you need to convert them into a specified format, such as "yyyy year MM month dd day", etc. In GTM, you need to convert the time into Unix timestamp, UTC time and other formats.

2. Use jQuery to get the time

In jQuery, we can use the Date object to get the current time. The method is as follows:

var date = new Date(); // 获取当前时间
var year = date.getFullYear(); // 获取当前年份，例如2021
var month = date.getMonth(); // 获取当前月份，从0开始，例如0表示1月，11表示12月
var day = date.getDate(); // 获取当前天数，例如1~31
var hours = date.getHours(); // 获取当前小时数，例如0~23
var minutes = date.getMinutes(); // 获取当前分钟数，例如0~59
var seconds = date.getSeconds(); // 获取当前秒数，例如0~59

3. Use jQuery to format the time

In jQuery, we can use the .format() method to format the time as follows:

var date = new Date();
var year = date.getFullYear();
var month = date.getMonth()+1; //月份从0到11，需要加1
var day = date.getDate();
var hours = date.getHours();
var minutes = date.getMinutes();
var seconds = date.getSeconds();

var formatTime = year + '-' + month + '-' + day + ' ' + hours + ':' + minutes + ':' + seconds;

The above method can format the current time into "yyyy-MM-dd HH:mm:ss " format.

4. Use jQuery to implement Unix timestamp

In GTM, the Unix timestamp refers to the number of seconds that have elapsed from January 1, 1970 to the present. Therefore, if you need to convert the current time to a Unix timestamp, you can use the following jQuery code to achieve it:

var date = new Date();
var unixTime = date.getTime() / 1000; //获取1970年1月1日0时0分0秒到当前时间的秒数

5. Use jQuery to implement UTC time

In GTM, UTC time does not mean Universal Time taking into account the effects of daylight saving time. The following is the jQuery code to convert the current time to UTC time:

var date = new Date();
var utcTime = date.toISOString(); //获取当前时间的UTC时间

The above method can convert the current time to the format of "yyyy-MM-ddTHH:mm:ss.sssZ", where T represents the time separator , Z represents the UTC time zone identifier.

6. Summary

Through the above introduction, we can see that using jQuery and GTM to quickly format and convert time formats can greatly improve the efficiency of developers and facilitate data tracking and analyze. I hope this article can help website developers better understand and use jQuery and GTM to achieve better website optimization.
