I'm encountering an issue with validating the specified string obtained from the new Date() Object.
"2020-10-06T14:23:43.964Z"new Date(). My aim is to create something that can handle this scenario, similar to:
const checkDateValidity = (d: Date):boolean => {
if (d instanceof Date || /* validate Date string here */) {
return true
}
return false
}
Here is a helpful solution for you.
Date.prototype.checkValidity = function () {
// This function checks if the date object is valid by comparing the getTime() method
// If it returns 'NaN', it means the date is invalid.
return this.getTime() === this.getTime();
};
After finding the second half of my issue in this post, which provides more detailed information about javascript regex iso datetime
The function I devised is intended to verify whether the input is a Date object instance or a string that matches the output of the Date object.
function checkDateValidity (input) {
if (input instanceof Date) {
return true;
}
return /\d{4}-[01]\d-[0-3]\dT[0-2]\d:[0-5]\d:[0-5]\d\.\d+([+-][0-2]\d:[0-5]\d|Z)/.test(input) ? true : false
}
const date1 = new Date(); // true
const date2 = '2020-10-05'; // false
const date3 = '2020-10-06T14:23:43.964Z'; // true
console.log(checkDateValidity(date1))
console.log(checkDateValidity(date2))
