How to dynamically display the day of the week using Vue.js

With the development of the Internet, front-end technology is constantly being upgraded and updated. As a modern JavaScript framework, Vue.js is used by more and more developers. In Vue.js, we often need to display the current date and time, especially which day of the week it is. This article will introduce how to use Vue.js to dynamically display the day of the week.

1. Get the current date

To get the current date, we need to use the built-in object Date in JavaScript. First, we need to get the current date through the following code.

let today = new Date();

This line of code will create a Date object and assign it to the variable today.

2. Get the current day of the week

To get the current day of the week, we can use the getDay() method of the Date object. This method will return a number between 0 and 6, representing Sunday to Saturday respectively.

let weekday = today.getDay();

At this time, the variable weekday stores a number between 0 and 6.

3. Display the day of the week

Now we can convert the numbers into the corresponding text of the day of the week. In order to achieve this function, we can dynamically generate the day of the week through the calculated property in Vue.js. The following code demonstrates how to display the day of the week using a computed property.

In the above code, we define a calculated attribute weekDay, which automatically generates the day of the week text based on the date of the day. At this time, we only need to use {{ weekDay }} directly in the template to dynamically display which day of the week it is today.

4. Add styles

In order to make our page more beautiful, we can add some styles to the day of the week text. The code below will set the day of the week text to red and make it larger.

Run the above code, you will see that the day of the week corresponding to the current date is dynamically displayed on the page, and the text will be displayed in red and enlarged.
