Convert jquery string timestamp into

Date and Time

jQuery is a widely used Javascript library that makes Javascript development easier and more portable. In web development, it is often necessary to convert string timestamps into dates and times, because the format of string timestamps does not conform to the way humans are used to expressing time and date.

This article will introduce how to use jQuery to convert a string timestamp into date and time format.

1. Definition of timestamp

A timestamp is a way for computers to store time. It is the number of seconds that have passed since January 1, 1970. Therefore, the larger the value of a timestamp, the closer the time represented is to the present. Timestamps are usually expressed as integers or decimals.

2. Convert timestamp to date and time format

Sometimes, the timestamp format of a string does not meet our needs and needs to be converted to date and time The format of the time. The following is a method to convert timestamps into date and time:

2.1 Using JavaScript’s Date object

JavaScript’s Date object supports converting timestamps into date and time formats. Just pass the timestamp as a parameter to the Date object.

var timestamp = 1609459200;
var date = new Date(timestamp * 1000);
console.log(date.toLocaleDateString()); // "1/1/2021"
console.log(date.toLocaleTimeString()); // "12:00:00 AM"

The above code converts the timestamp into the date and time format in the current time zone, and presents it through the toLocaleDateString() and toLocaleTimeString() methods.

It should be noted that the JavaScript Date object treats the timestamp as the number of milliseconds since January 1, 1970, and the timestamp is expressed in seconds, so the timestamp needs to be multiplied Take 1000.

2.2 Using the jQuery plugin moment.js

moment.js is a popular JavaScript date and time processing library that simplifies the processing of common operations. Use moment.js to convert timestamps into date and time formats faster and more directly. The following is the moment.js code that converts a timestamp into date and time format:

var timestamp = 1609459200;
var date = moment.unix(timestamp);
console.log(date.format('MM/DD/YYYY')); // "01/01/2021"
console.log(date.format('HH:mm:ss A')); // "12:00:00 AM"

The above code uses the Unix() method of moment.js to convert the timestamp into a Unix timestamp, and then uses .format() Method formats the date and time into the desired string format.

3. Summary

This article introduces how to convert a string timestamp into date and time format. Using JavaScript's Date object or the moment.js library can help us process date and time formats faster. We can use these methods to easily convert timestamps into more humane date and time formats, making the data easier to understand and use.
