How to convert seconds into 'hours, minutes and seconds' format in vue

Apr 07, 2023 am 09:29 AM

Vue.js is one of the more popular front-end frameworks at present. It provides a lot of basic components and tool libraries to facilitate developers to quickly build reusable web applications. In Vue.js, we sometimes need to convert seconds into a format such as "hours, minutes and seconds", which requires the use of formatting time techniques.

1. Using the Date library

In Vue.js, formatting time into the required string is a common requirement. Here, we can use JavaScript's native Date library to achieve this.

The specific steps are as follows:

1. Convert seconds to milliseconds

First, we need to convert the given number of seconds into milliseconds, which can be done by multiplying Do it with 1000.

let time = 1234; // 1234秒
let ms = time * 1000; // 1234000毫秒
Copy after login

2. Construct a Date object

Then, we can use the Date constructor to create a new Date instance.

let time = 1234; // 1234秒
let ms = time * 1000; // 1234000毫秒
let date = new Date(ms);
Copy after login

3. Formatting time

Finally, we can use the methods on the Date prototype to format the time, such as using the getFullYear method to get the year, the getMonth method to get the month, the getDay method to get the date, etc. wait.

For converting seconds into hours, minutes and seconds format, we can implement it as follows:

let time = 1234; // 1234秒
let ms = time * 1000; // 1234000毫秒
let date = new Date(ms);

let hour = date.getHours();
let minute = date.getMinutes();
let second = date.getSeconds();

let formatTime = `${hour.toString().padStart(2, '0')}:${minute.toString().padStart(2, '0')}:${second.toString().padStart(2, '0')}`;

console.log(formatTime); // "00:20:34"
Copy after login

In the above example, we obtain the hours and minutes of the time through the getHours, getMinutes and getSeconds methods and seconds, and use the padStart function to set them to two digits.

2. Use day.js

Day.js is a lightweight JavaScript date parsing and formatting library. It is very suitable for rapid development in Vue.js projects.

Using Day.js to format time is very simple. We can do it through the following steps:

1. Install Day.js

First, in the Vue.js project Install Day.js in . You can use the npm package manager to install:

npm install dayjs
Copy after login

or use CDN to introduce the Day.js library file:

<script src="https://cdn.jsdelivr.net/npm/dayjs"></script>
Copy after login

2. Import Day.js

in Vue. Import Day.js into the js component and bind it to the component's data:

import dayjs from 'dayjs';

export default {
  data() {
    return {
      dayjs: dayjs,
      time: 1234
    };
  }
}
Copy after login

3. Formatting time

Finally, we can use the format function provided by Day.js Format time.

<template>
  <div>
    {{dayjs(time * 1000).format('HH:mm:ss')}}
  </div>
</template>
Copy after login

In the above example, we created a Day.js instance through the dayjs function, took the time that needs to be formatted as a parameter of its constructor, and used the format function to convert it into the required format. (in this case "HH:mm:ss").

Conclusion

In general, formatting time in Vue.js is very simple. We can use the native Date library or the third-party library Day.js to achieve it. The methods introduced here are only two of them. You can choose the appropriate method to implement according to your actual needs.
