Year setting in jquery

With the rapid development of the Internet, web development has become more and more important. Among them, using JavaScript libraries is a good choice for developers because they provide a simple and easy-to-use method to implement common web functions and user interface interaction effects. Among them, jQuery is one of the most popular JavaScript libraries, which is widely used to handle DOM operations and event handling.

In web applications, date and time are essential elements, and it is often necessary to obtain the user's current year for various data display and calculations. In this article, we will learn how to set and get the year using jQuery.

1. Get the current year

To get the current year, we can use JavaScript’s Date object.

First, we need to create a new Date object:

var date = new Date();

Then, we can use the getFullYear() method to get the current year:

var year = date.getFullYear();

Use the console.log() function to output the year:

console.log(year);

The complete code is as follows:

var date = new Date();
var year = date.getFullYear();
console.log(year);

2. Set the year

Setting the year is a simple matter. We only need to use the setFullYear() method.

For example, if we want to set the current year to 2050, we can write:

var date = new Date();
date.setFullYear(2050);

Then, we can use the getFullYear() method to confirm whether the year has been set Set to 2050:

var year = date.getFullYear();
console.log(year);

The complete code is as follows:

var date = new Date();
date.setFullYear(2050);
var year = date.getFullYear();
console.log(year);

3. Get the specified year

If we need to get the data of a specified year, You can use the new Date() constructor to create a new Date object.

For example, if we want to get the data in 2022, we can write like this:

var date = new Date("2022-01-01");
var year = date.getFullYear();
console.log(year);

This code will create a new Date object with the date of January 1, 2022, and then use getFullYear()Method to get the year. The output should be 2022.

The complete code is as follows:

var date = new Date("2022-01-01");
var year = date.getFullYear();
console.log(year);
