Analyzing Varied Date Formats

I'm looking to create a function in AngularJS that checks if a given date is after today:

$scope.isAfterToday= function(inputDate){
    if(inputDate > Date.now().toString()){
        return true;
    } else {
        return false;
    }
}

The issue I am facing is that the inputDate parameter comes in the format "2016-10-12T00:00:00" which is different from the output of the Date.now() function. Is there a simple way to convert between these formats without manually extracting the month, day, and year from each for comparison?

Appreciate any guidance on this matter!

Answer №1

function checkIfAfterToday(input){
    //Find out if the date is after today
    var time = new Date().setHours(0,0,0,0); //Set to midnight of today
    time.setDate(time.getDate() + 1); //Get midnight of tomorrow
    return (new Date(input) > time);
};

You don't need any external library for this task. Comparing Date objects directly is sufficient, and the constructor can handle various date formats as input.

For comparing Date objects, you can utilize standard comparison operators:

<
>
<=
>=

Avoid using == as it compares object references rather than values.

Answer №2

To convert the inputDate into a standard Date object, simply use the following code:

new Date("2016-10-12T00:00:00").getTime(); // this will give you 1476230521000

You can also use new Date().toISOString(); to revert back.

Answer №3

Utilize the Date object to convert your inputDate into a numerical value representing milliseconds for easy comparison.

var convertedInput = new Date(inputDate);

If you want to display the date in a formatted way, there is no built-in method for this. However, converting milliseconds back into a readable date format is relatively straightforward!

var today = new Date();
var day = today.getDate();
var month = today.getMonth() + 1; //Months are zero-based
var year = today.getFullYear();
var datenow = year + "-" + month + "-" + day;
