Convert milliseconds to hours, minutes and seconds with jquery

Today, we will explore how to convert milliseconds to hours, minutes and seconds format using jQuery. Since many programs and applications need to work with time formats, converting milliseconds into a readable hour, minute, and second format is often necessary.

In this tutorial, we will use jQuery and JavaScript to achieve this goal. We will create a custom function that will accept milliseconds and convert them to hour minutes seconds format.

First, let’s look at the formula for converting milliseconds:

var milliseconds = 1000;
var seconds = 60;
var minutes = 60;
var hours = 24;
var days_to_milliseconds = 86400000;

var current_time_in_milliseconds = new Date().getTime();
var time_difference_in_milliseconds = current_time_in_milliseconds - start_time_in_milliseconds;

var seconds_since_start = Math.floor(time_difference_in_milliseconds / milliseconds);
var minutes_since_start = Math.floor(seconds_since_start / seconds);
var hours_since_start = Math.floor(minutes_since_start / minutes);
var days_since_start = Math.floor(hours_since_start / hours);

// Display the result in the console
console.log(days_since_start + ' days, ' + hours_since_start % 24 + ' hours, ' + minutes_since_start % 60 + ' minutes, and ' + seconds_since_start % 60 + ' seconds since start.');

Now let’s apply this formula to our jQuery function to convert milliseconds:

function millisecondsToTime(ms) {
  var milliseconds = 1000;
  var seconds = 60;
  var minutes = 60;
  var hours = 24;
  var days_to_milliseconds = 86400000;

  var time_difference_in_milliseconds = ms;

  var seconds_since_start = Math.floor(time_difference_in_milliseconds / milliseconds);
  var minutes_since_start = Math.floor(seconds_since_start / seconds);
  var hours_since_start = Math.floor(minutes_since_start / minutes);
  var days_since_start = Math.floor(hours_since_start / hours);

  // Format the result
  var result = '';
  if (days_since_start > 0) {
    result += days_since_start + '天 ';
  }
  if (hours_since_start > 0) {
    result += hours_since_start % 24 + '小时 ';
  }
  if (minutes_since_start > 0) {
    result += minutes_since_start % 60 + '分钟 ';
  }

  // Add the seconds
  result += seconds_since_start % 60 + '秒';

  return result;
}

In the above function, we created variables for each time unit and used the floor function to round the time difference to the nearest integer. We then calculated the amount of each time unit based on the time difference and added it to the result string as needed.

Now we just need to pass the required number of milliseconds to our custom function and it will return the converted formatted time string. Our function can be called like this:

var milliseconds = 500000; // This is the number of milliseconds we want to convert
var time_string = millisecondsToTime(milliseconds);
console.log(time_string); // Outputs "8分钟 20秒"

In the above code, we passed 500000 milliseconds to our custom function and assigned the returned string to a variable. Finally, we output the resulting string in the console, which will read "8 minutes and 20 seconds".

Summary

In this article, we showed you how to convert milliseconds into a readable hour, minute, and second format using jQuery and JavaScript. By writing a custom function and rounding the time difference to the nearest integer, we can create a formatted time string. This method can be used in many applications and programs, especially those that require processing time.
