I am beginner using bootstrap PDO and php. javascript How can I compare 2 date like image below.

CodePudding user response：

It depens on when/where u want to compare them. While filling out the form will require JS/Jquery. After submitting requires PHP.

In PHP it should work like this:

$date1 = "2022-02-02";
$date2 = "2021-01-01";
$dateTime1 = strtotime($date1);
$dateTime2 = strtotime($date2);

if ($dateTime1 > $dateTime2){
   echo "$date1 is latest than $date2";
}else{
   echo "$date1 is older than $date2";
}

PHP manual strtotime().

For JQuery use this thread.

To compare dates you can use the .toString() method:

const d1 = new Date('2019-06-01');
const d2 = new Date('2018-06-01');
const d3 = new Date('2019-06-01');

console.log(d1.toString() === d2.toString()); // false
console.log(d1.toString() === d3.toString()); // true
