flatpickr $input._flatpicker from jquery input

Question

I use jquery in my project and I am putting the date drop down in place with flatpickr. I need to grab the existing instance of flatpickr from my date input, but using jquery it doens't work. I am looking for the answer on getting the flatpickr instance from an input that is using jquery.

function flatpickrMinDate($openDate, $closeDate) {
    const fp = $closeDate._flatpickr;
    if (fp === null || fp === undefined) return;
    fp.set('minDate', $openDate.value);
}

// this works

flatpickrMinDate(document.querySelector("#dateOpen"), document.querySelector("#dateClosed"));

// with jquery, the following does not work

flatpickrMinDate($("#dateOpen"), $("#dateClosed"));

in flatpickrMinDate, $closeDate._flatpickr returns undefined. It should return a flatpickr instance, but it returns undefined instead.

When using jQuery, you need to extract the DOM elements from the jQuery objects before passing them to the function. Use one of these methods to extract the element:

flatpickrMinDate($("#dateOpen").get(0), $("#dateClosed").get(0));

or

flatpickrMinDate($("#dateOpen")[0], $("#dateClosed")[0]);
