$.getJSON("api/times", function(times) {
var time1 = times.departure; // 14:36:30 (string)
var minutesToAdd = parseInt(times.minutesToAdd); // 6
var total = "?"; // How can I add minutesToAdd to time1?
});
I need to manipulate the time1 variable in order to add the value of minutesToAdd to it. The initial value of time1 is retrieved from a MySQL database and obtained through an API that provides the data in JSON format. What would be the best approach to achieve this?
Here's a helpful suggestion for you:
In order to work with dates and times in JavaScript, it's important to include a demo date along with the time. This will allow you to create a date object that can be manipulated as needed. By using the getTime() method, you can retrieve the time in milliseconds.
var newDateObj = new Date("01/01/13 14:36:30"); // '01/01/13' is just an example date
alert(newDateObj)
var date = new Date(newDateObj.getTime() + 5*60000);
alert(date) // Use date.getTime() to get the time value
If you prefer not to utilize Date, consider using the split function to extract the three components of your time string. Then proceed by adding the specified minutes while ensuring not to exceed 59 minutes (and also verifying that the hours do not go over 23 if deemed necessary):
$.getJSON("api/times", function(times) {
var time1 = times.departure; // 14:36:30 (string)
var minutesToAdd = parseInt(times.minutesToAdd);
var time = time1.split(':');
time[1] += minutesToAdd;
if (time[1] >= 60) {
time[1] = 0;
time[0]++; // You may want to validate this against 24
}
var total = time.join(':'); // This is equivalent to "time[0]+':'+time[1]+':'+time[2]"
});`
